+THE WORK (AS DEFINED BELOW) IS PROVIDED UNDER THE TERMS OF THIS CREATIVE
+COMMONS PUBLIC LICENSE ("CCPL" OR "LICENSE"). THE WORK IS PROTECTED BY
+COPYRIGHT AND/OR OTHER APPLICABLE LAW. ANY USE OF THE WORK OTHER THAN AS
+AUTHORIZED UNDER THIS LICENSE OR COPYRIGHT LAW IS PROHIBITED.
+
+BY EXERCISING ANY RIGHTS TO THE WORK PROVIDED HERE, YOU ACCEPT AND AGREE
+TO BE BOUND BY THE TERMS OF THIS LICENSE. TO THE EXTENT THIS LICENSE MAY
+BE CONSIDERED TO BE A CONTRACT, THE LICENSOR GRANTS YOU THE RIGHTS
+CONTAINED HERE IN CONSIDERATION OF YOUR ACCEPTANCE OF SUCH TERMS AND
+CONDITIONS.
+
+1. Definitions
+
+ a. "Adaptation" means a work based upon the Work, or upon the Work and
+ other pre-existing works, such as a translation, adaptation,
+ derivative work, arrangement of music or other alterations of a
+ literary or artistic work, or phonogram or performance and includes
+ cinematographic adaptations or any other form in which the Work may be
+ recast, transformed, or adapted including in any form recognizably
+ derived from the original, except that a work that constitutes a
+ Collection will not be considered an Adaptation for the purpose of
+ this License. For the avoidance of doubt, where the Work is a musical
+ work, performance or phonogram, the synchronization of the Work in
+ timed-relation with a moving image ("synching") will be considered an
+ Adaptation for the purpose of this License.
+ b. "Collection" means a collection of literary or artistic works, such as
+ encyclopedias and anthologies, or performances, phonograms or
+ broadcasts, or other works or subject matter other than works listed
+ in Section 1(f) below, which, by reason of the selection and
+ arrangement of their contents, constitute intellectual creations, in
+ which the Work is included in its entirety in unmodified form along
+ with one or more other contributions, each constituting separate and
+ independent works in themselves, which together are assembled into a
+ collective whole. A work that constitutes a Collection will not be
+ considered an Adaptation (as defined above) for the purposes of this
+ License.
+ c. "Distribute" means to make available to the public the original and
+ copies of the Work or Adaptation, as appropriate, through sale or
+ other transfer of ownership.
+ d. "Licensor" means the individual, individuals, entity or entities that
+ offer(s) the Work under the terms of this License.
+ e. "Original Author" means, in the case of a literary or artistic work,
+ the individual, individuals, entity or entities who created the Work
+ or if no individual or entity can be identified, the publisher; and in
+ addition (i) in the case of a performance the actors, singers,
+ musicians, dancers, and other persons who act, sing, deliver, declaim,
+ play in, interpret or otherwise perform literary or artistic works or
+ expressions of folklore; (ii) in the case of a phonogram the producer
+ being the person or legal entity who first fixes the sounds of a
+ performance or other sounds; and, (iii) in the case of broadcasts, the
+ organization that transmits the broadcast.
+ f. "Work" means the literary and/or artistic work offered under the terms
+ of this License including without limitation any production in the
+ literary, scientific and artistic domain, whatever may be the mode or
+ form of its expression including digital form, such as a book,
+ pamphlet and other writing; a lecture, address, sermon or other work
+ of the same nature; a dramatic or dramatico-musical work; a
+ choreographic work or entertainment in dumb show; a musical
+ composition with or without words; a cinematographic work to which are
+ assimilated works expressed by a process analogous to cinematography;
+ a work of drawing, painting, architecture, sculpture, engraving or
+ lithography; a photographic work to which are assimilated works
+ expressed by a process analogous to photography; a work of applied
+ art; an illustration, map, plan, sketch or three-dimensional work
+ relative to geography, topography, architecture or science; a
+ performance; a broadcast; a phonogram; a compilation of data to the
+ extent it is protected as a copyrightable work; or a work performed by
+ a variety or circus performer to the extent it is not otherwise
+ considered a literary or artistic work.
+ g. "You" means an individual or entity exercising rights under this
+ License who has not previously violated the terms of this License with
+ respect to the Work, or who has received express permission from the
+ Licensor to exercise rights under this License despite a previous
+ violation.
+ h. "Publicly Perform" means to perform public recitations of the Work and
+ to communicate to the public those public recitations, by any means or
+ process, including by wire or wireless means or public digital
+ performances; to make available to the public Works in such a way that
+ members of the public may access these Works from a place and at a
+ place individually chosen by them; to perform the Work to the public
+ by any means or process and the communication to the public of the
+ performances of the Work, including by public digital performance; to
+ broadcast and rebroadcast the Work by any means including signs,
+ sounds or images.
+ i. "Reproduce" means to make copies of the Work by any means including
+ without limitation by sound or visual recordings and the right of
+ fixation and reproducing fixations of the Work, including storage of a
+ protected performance or phonogram in digital form or other electronic
+ medium.
+
+2. Fair Dealing Rights. Nothing in this License is intended to reduce,
+limit, or restrict any uses free from copyright or rights arising from
+limitations or exceptions that are provided for in connection with the
+copyright protection under copyright law or other applicable laws.
+
+3. License Grant. Subject to the terms and conditions of this License,
+Licensor hereby grants You a worldwide, royalty-free, non-exclusive,
+perpetual (for the duration of the applicable copyright) license to
+exercise the rights in the Work as stated below:
+
+ a. to Reproduce the Work, to incorporate the Work into one or more
+ Collections, and to Reproduce the Work as incorporated in the
+ Collections;
+ b. to create and Reproduce Adaptations provided that any such Adaptation,
+ including any translation in any medium, takes reasonable steps to
+ clearly label, demarcate or otherwise identify that changes were made
+ to the original Work. For example, a translation could be marked "The
+ original work was translated from English to Spanish," or a
+ modification could indicate "The original work has been modified.";
+ c. to Distribute and Publicly Perform the Work including as incorporated
+ in Collections; and,
+ d. to Distribute and Publicly Perform Adaptations.
+ e. For the avoidance of doubt:
+
+ i. Non-waivable Compulsory License Schemes. In those jurisdictions in
+ which the right to collect royalties through any statutory or
+ compulsory licensing scheme cannot be waived, the Licensor
+ reserves the exclusive right to collect such royalties for any
+ exercise by You of the rights granted under this License;
+ ii. Waivable Compulsory License Schemes. In those jurisdictions in
+ which the right to collect royalties through any statutory or
+ compulsory licensing scheme can be waived, the Licensor waives the
+ exclusive right to collect such royalties for any exercise by You
+ of the rights granted under this License; and,
+ iii. Voluntary License Schemes. The Licensor waives the right to
+ collect royalties, whether individually or, in the event that the
+ Licensor is a member of a collecting society that administers
+ voluntary licensing schemes, via that society, from any exercise
+ by You of the rights granted under this License.
+
+The above rights may be exercised in all media and formats whether now
+known or hereafter devised. The above rights include the right to make
+such modifications as are technically necessary to exercise the rights in
+other media and formats. Subject to Section 8(f), all rights not expressly
+granted by Licensor are hereby reserved.
+
+4. Restrictions. The license granted in Section 3 above is expressly made
+subject to and limited by the following restrictions:
+
+ a. You may Distribute or Publicly Perform the Work only under the terms
+ of this License. You must include a copy of, or the Uniform Resource
+ Identifier (URI) for, this License with every copy of the Work You
+ Distribute or Publicly Perform. You may not offer or impose any terms
+ on the Work that restrict the terms of this License or the ability of
+ the recipient of the Work to exercise the rights granted to that
+ recipient under the terms of the License. You may not sublicense the
+ Work. You must keep intact all notices that refer to this License and
+ to the disclaimer of warranties with every copy of the Work You
+ Distribute or Publicly Perform. When You Distribute or Publicly
+ Perform the Work, You may not impose any effective technological
+ measures on the Work that restrict the ability of a recipient of the
+ Work from You to exercise the rights granted to that recipient under
+ the terms of the License. This Section 4(a) applies to the Work as
+ incorporated in a Collection, but this does not require the Collection
+ apart from the Work itself to be made subject to the terms of this
+ License. If You create a Collection, upon notice from any Licensor You
+ must, to the extent practicable, remove from the Collection any credit
+ as required by Section 4(b), as requested. If You create an
+ Adaptation, upon notice from any Licensor You must, to the extent
+ practicable, remove from the Adaptation any credit as required by
+ Section 4(b), as requested.
+ b. If You Distribute, or Publicly Perform the Work or any Adaptations or
+ Collections, You must, unless a request has been made pursuant to
+ Section 4(a), keep intact all copyright notices for the Work and
+ provide, reasonable to the medium or means You are utilizing: (i) the
+ name of the Original Author (or pseudonym, if applicable) if supplied,
+ and/or if the Original Author and/or Licensor designate another party
+ or parties (e.g., a sponsor institute, publishing entity, journal) for
+ attribution ("Attribution Parties") in Licensor's copyright notice,
+ terms of service or by other reasonable means, the name of such party
+ or parties; (ii) the title of the Work if supplied; (iii) to the
+ extent reasonably practicable, the URI, if any, that Licensor
+ specifies to be associated with the Work, unless such URI does not
+ refer to the copyright notice or licensing information for the Work;
+ and (iv) , consistent with Section 3(b), in the case of an Adaptation,
+ a credit identifying the use of the Work in the Adaptation (e.g.,
+ "French translation of the Work by Original Author," or "Screenplay
+ based on original Work by Original Author"). The credit required by
+ this Section 4 (b) may be implemented in any reasonable manner;
+ provided, however, that in the case of a Adaptation or Collection, at
+ a minimum such credit will appear, if a credit for all contributing
+ authors of the Adaptation or Collection appears, then as part of these
+ credits and in a manner at least as prominent as the credits for the
+ other contributing authors. For the avoidance of doubt, You may only
+ use the credit required by this Section for the purpose of attribution
+ in the manner set out above and, by exercising Your rights under this
+ License, You may not implicitly or explicitly assert or imply any
+ connection with, sponsorship or endorsement by the Original Author,
+ Licensor and/or Attribution Parties, as appropriate, of You or Your
+ use of the Work, without the separate, express prior written
+ permission of the Original Author, Licensor and/or Attribution
+ Parties.
+ c. Except as otherwise agreed in writing by the Licensor or as may be
+ otherwise permitted by applicable law, if You Reproduce, Distribute or
+ Publicly Perform the Work either by itself or as part of any
+ Adaptations or Collections, You must not distort, mutilate, modify or
+ take other derogatory action in relation to the Work which would be
+ prejudicial to the Original Author's honor or reputation. Licensor
+ agrees that in those jurisdictions (e.g. Japan), in which any exercise
+ of the right granted in Section 3(b) of this License (the right to
+ make Adaptations) would be deemed to be a distortion, mutilation,
+ modification or other derogatory action prejudicial to the Original
+ Author's honor and reputation, the Licensor will waive or not assert,
+ as appropriate, this Section, to the fullest extent permitted by the
+ applicable national law, to enable You to reasonably exercise Your
+ right under Section 3(b) of this License (right to make Adaptations)
+ but not otherwise.
+
+5. Representations, Warranties and Disclaimer
+
+UNLESS OTHERWISE MUTUALLY AGREED TO BY THE PARTIES IN WRITING, LICENSOR
+OFFERS THE WORK AS-IS AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY
+KIND CONCERNING THE WORK, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE,
+INCLUDING, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTIBILITY,
+FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT, OR THE ABSENCE OF
+LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OF ABSENCE OF ERRORS,
+WHETHER OR NOT DISCOVERABLE. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION
+OF IMPLIED WARRANTIES, SO SUCH EXCLUSION MAY NOT APPLY TO YOU.
+
+6. Limitation on Liability. EXCEPT TO THE EXTENT REQUIRED BY APPLICABLE
+LAW, IN NO EVENT WILL LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY FOR
+ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES
+ARISING OUT OF THIS LICENSE OR THE USE OF THE WORK, EVEN IF LICENSOR HAS
+BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+7. Termination
+
+ a. This License and the rights granted hereunder will terminate
+ automatically upon any breach by You of the terms of this License.
+ Individuals or entities who have received Adaptations or Collections
+ from You under this License, however, will not have their licenses
+ terminated provided such individuals or entities remain in full
+ compliance with those licenses. Sections 1, 2, 5, 6, 7, and 8 will
+ survive any termination of this License.
+ b. Subject to the above terms and conditions, the license granted here is
+ perpetual (for the duration of the applicable copyright in the Work).
+ Notwithstanding the above, Licensor reserves the right to release the
+ Work under different license terms or to stop distributing the Work at
+ any time; provided, however that any such election will not serve to
+ withdraw this License (or any other license that has been, or is
+ required to be, granted under the terms of this License), and this
+ License will continue in full force and effect unless terminated as
+ stated above.
+
+8. Miscellaneous
+
+ a. Each time You Distribute or Publicly Perform the Work or a Collection,
+ the Licensor offers to the recipient a license to the Work on the same
+ terms and conditions as the license granted to You under this License.
+ b. Each time You Distribute or Publicly Perform an Adaptation, Licensor
+ offers to the recipient a license to the original Work on the same
+ terms and conditions as the license granted to You under this License.
+ c. If any provision of this License is invalid or unenforceable under
+ applicable law, it shall not affect the validity or enforceability of
+ the remainder of the terms of this License, and without further action
+ by the parties to this agreement, such provision shall be reformed to
+ the minimum extent necessary to make such provision valid and
+ enforceable.
+ d. No term or provision of this License shall be deemed waived and no
+ breach consented to unless such waiver or consent shall be in writing
+ and signed by the party to be charged with such waiver or consent.
+ e. This License constitutes the entire agreement between the parties with
+ respect to the Work licensed here. There are no understandings,
+ agreements or representations with respect to the Work not specified
+ here. Licensor shall not be bound by any additional provisions that
+ may appear in any communication from You. This License may not be
+ modified without the mutual written agreement of the Licensor and You.
+ f. The rights granted under, and the subject matter referenced, in this
+ License were drafted utilizing the terminology of the Berne Convention
+ for the Protection of Literary and Artistic Works (as amended on
+ September 28, 1979), the Rome Convention of 1961, the WIPO Copyright
+ Treaty of 1996, the WIPO Performances and Phonograms Treaty of 1996
+ and the Universal Copyright Convention (as revised on July 24, 1971).
+ These rights and subject matter take effect in the relevant
+ jurisdiction in which the License terms are sought to be enforced
+ according to the corresponding provisions of the implementation of
+ those treaty provisions in the applicable national law. If the
+ standard suite of rights granted under applicable copyright law
+ includes additional rights not granted under this License, such
+ additional rights are deemed to be included in the License; this
+ License is not intended to restrict the license of any rights under
+ applicable law.

+ license. Notwithstanding the foregoing two (2) sentences, if Creative

+ shall have all rights and obligations of Licensor.

+A port of the browser's `btoa` function.
+
+Uses `Buffer` to emulate the exact functionality of the browser's btoa
+(except that it supports some unicode that the browser may not).
+
+It turns binary data __to__ base64-encoded ascii.

+CircularJSON
+============
+
+[](https://github.com/WebReflection/donate)  [](https://travis-ci.org/WebReflection/circular-json) [](https://coveralls.io/github/WebReflection/circular-json?branch=master)
+
+Serializes and deserializes otherwise valid JSON objects containing circular references into and from a specialized JSON format.
+
+- - -
+
+## The future of this module is called [flatted](https://github.com/WebReflection/flatted#flatted)
+
+Smaller, faster, and able to produce on average a reduced output too, [flatted](https://github.com/WebReflection/flatted#flatted) is the new, bloatless, ESM and CJS compatible, circular JSON parser.
+
+It has now reached V1 and it implements the exact same JSON API.
+
+Please note **CircularJSON is in maintenance only** and **[flatted](https://github.com/WebReflection/flatted#flatted) is its successor**.
+
+- - -
+
+### A Working Solution To A Common Problem
+A usage example:
+
+```JavaScript
+var object = {};
+object.arr = [
+ object, object
+];
+object.arr.push(object.arr);
+object.obj = object;
+
+var serialized = CircularJSON.stringify(object);
+// '{"arr":["~","~","~arr"],"obj":"~"}'
+// NOTE: CircularJSON DOES NOT parse JS
+// it handles receiver and reviver callbacks
+
+var unserialized = CircularJSON.parse(serialized);
+// { arr: [ [Circular], [Circular] ],
+// obj: [Circular] }
+
+unserialized.obj === unserialized;
+unserialized.arr[0] === unserialized;
+unserialized.arr.pop() === unserialized.arr;
+```
+
+A quick summary:
+
+ * **new** in version `0.5`, you can specify a JSON parser different from JSON itself. `CircularJSON.parser = ABetterJSON;` is all you need.
+ * uses `~` as a special prefix symbol to denote which parent the reference belongs to (i.e. `~root~child1~child2`)
+ * reasonably fast in both serialization and deserialization
+ * compact serialization for easier and slimmer transportation across environments
+ * [tested and covered](test/circular-json.js) over nasty structures too
+ * compatible with all JavaScript engines
+
+Node Installation & Usage
+============
+
+```bash
+npm install --save circular-json
+```
+
+```javascript
+'use strict';
+
+var
+ CircularJSON = require('circular-json'),
+ obj = { foo: 'bar' },
+ str
+;
+
+obj.self = obj;
+str = CircularJSON.stringify(obj);
+```
+
+There are no dependencies.
+
+Browser Installation & Usage
+================
+
+* Global:
+* AMD:
+* CommonJS:
+
+(generated via [gitstrap](https://github.com/WebReflection/gitstrap))
+
+```html
+
+```
+
+```javascript
+'use strict';
+
+var CircularJSON = window.CircularJSON
+ , obj = { foo: 'bar' }
+ , str
+ ;
+
+obj.self = obj;
+str = CircularJSON.stringify(obj);
+```
+
+NOTE: Platforms without native JSON (i.e. MSIE <= 8) requires `json3.js` or similar.
+
+It is also *a bad idea* to `CircularJSON.parse(JSON.stringify(object))` because of those manipulation used in `CircularJSON.stringify()` able to make parsing safe and secure.
+
+As summary: `CircularJSON.parse(CircularJSON.stringify(object))` is the way to go, same is for `JSON.parse(JSON.stringify(object))`.
+
+API
+===
+
+It's the same as native JSON, except the fourth parameter `placeholder`, which circular references to be replaced with `"[Circular]"` (i.e. for logging).
+
+* CircularJSON.stringify(object, replacer, spacer, placeholder)
+* CircularJSON.parse(string, reviver)
+
+Bear in mind `JSON.parse(CircularJSON.stringify(object))` will work but not produce the expected output.
+
+Similar Libraries
+=======
+
+### Why Not the [@izs](https://twitter.com/izs) One
+The module [json-stringify-safe](https://github.com/isaacs/json-stringify-safe) seems to be for `console.log()` but it's completely pointless for `JSON.parse()`, being latter one unable to retrieve back the initial structure. Here an example:
+
+```JavaScript
+// a logged object with circular references
+{
+ "circularRef": "[Circular]",
+ "list": [
+ "[Circular]",
+ "[Circular]"
+ ]
+}
+// what do we do with above output ?
+```
+
+Just type this in your `node` console: `var o = {}; o.a = o; console.log(o);`. The output will be `{ a: [Circular] }` ... good, but that ain't really solving the problem.
+
+However, if that's all you need, the function used to create that kind of output is probably faster than `CircularJSON` and surely fits in less lines of code.
+
+
+### Why Not {{put random name}} Solution
+So here the thing: circular references can be wrong but, if there is a need for them, any attempt to ignore them or remove them can be considered just a failure.
+
+Not because the method is bad or it's not working, simply because the circular info, the one we needed and used in the first place, is lost!
+
+In this case, `CircularJSON` does even more than just solve circular and recursions: it maps all same objects so that less memory is used as well on deserialization as less bandwidth too!
+It's able to redefine those references back later on so the way we store is the way we retrieve and in a reasonably performant way, also trusting the snappy and native `JSON` methods to iterate.

+
+
+## errno exposed
+
+Ever find yourself needing more details about Node.js errors? Me too, so *node-errno* contains the errno mappings direct from libuv so you can use them in your code.
+
+**By errno:**
+
+```js
+require('errno').errno[3]
+// → {
+// "errno": 3,
+// "code": "EACCES",
+// "description": "permission denied"
+// }
+```
+
+**By code:**
+
+```js
+require('errno').code.ENOTEMPTY
+// → {
+// "errno": 53,
+// "code": "ENOTEMPTY",
+// "description": "directory not empty"
+// }
+```
+
+**Make your errors more descriptive:**
+
+```js
+var errno = require('errno')
+
+function errmsg(err) {
+ var str = 'Error: '
+ // if it's a libuv error then get the description from errno
+ if (errno.errno[err.errno])
+ str += errno.errno[err.errno].description
+ else
+ str += err.message
+
+ // if it's a `fs` error then it'll have a 'path' property
+ if (err.path)
+ str += ' [' + err.path + ']'
+
+ return str
+}
+
+var fs = require('fs')
+
+fs.readFile('thisisnotarealfile.txt', function (err, data) {
+ if (err)
+ console.log(errmsg(err))
+})
+```
+
+**Use as a command line tool:**
+
+```
+~ $ errno 53
+{
+ "errno": 53,
+ "code": "ENOTEMPTY",
+ "description": "directory not empty"
+}
+~ $ errno EROFS
+{
+ "errno": 56,
+ "code": "EROFS",
+ "description": "read-only file system"
+}
+~ $ errno foo
+No such errno/code: "foo"
+```
+
+Supply no arguments for the full list. Error codes are processed case-insensitive.
+
+You will need to install with `npm install errno -g` if you want the `errno` command to be available without supplying a full path to the node_modules installation.
+
+
+## Custom errors
+
+Use `errno.custom.createError()` to create custom `Error` objects to throw around in your Node.js library. Create error hierarchies so `instanceof` becomes a useful tool in tracking errors. Call-stack is correctly captured at the time you create an instance of the error object, plus a `cause` property will make available the original error object if you pass one in to the constructor.
+
+```js
+var create = require('errno').custom.createError
+var MyError = create('MyError') // inherits from Error
+var SpecificError = create('SpecificError', MyError) // inherits from MyError
+var OtherError = create('OtherError', MyError)
+
+// use them!
+if (condition) throw new SpecificError('Eeek! Something bad happened')
+
+if (err) return callback(new OtherError(err))
+```
+
+Also available is a `errno.custom.FilesystemError` with in-built access to errno properties:
+
+```js
+fs.readFile('foo', function (err, data) {
+ if (err) return callback(new errno.custom.FilesystemError(err))
+ // do something else
+})
+```
+
+The resulting error object passed through the callback will have the following properties: `code`, `errno`, `path` and `message` will contain a descriptive human-readable message.

+# prr [](http://travis-ci.org/rvagg/prr)
+
+An sensible alternative to `Object.defineProperty()`. Available in npm and Ender as **prr**.
+
+## Usage
+
+Set the property `'foo'` (`obj.foo`) to have the value `'bar'` with default options (`'enumerable'`, `'configurable'` and `'writable'` are all `false`):
+
+```js
+prr(obj, 'foo', 'bar')
+```
+
+Adjust the default options:
+
+```js
+prr(obj, 'foo', 'bar', { enumerable: true, writable: true })
+```
+
+Do the same operation for multiple properties:
+
+```js
+prr(obj, { one: 'one', two: 'two' })
+// or with options:
+prr(obj, { one: 'one', two: 'two' }, { enumerable: true, writable: true })
+```
+
+### Simplify!
+
+But obviously, having to write out the full options object makes it nearly as bad as the original `Object.defineProperty()` so we can simplify.
+
+As an alternative method we can use an options string where each character represents a option: `'e'=='enumerable'`, `'c'=='configurable'` and `'w'=='writable'`:
+
+```js
+prr(obj, 'foo', 'bar', 'ew') // enumerable and writable but not configurable
+// muliple properties:
+prr(obj, { one: 'one', two: 'two' }, 'ewc') // configurable too
+```
+
+## Where can I use it?
+
+Anywhere! For pre-ES5 environments *prr* will simply fall-back to an `object[property] = value` so you can get close to what you want.
+
+*prr* is Ender-compatible so you can include it in your Ender build and `$.prr(...)` or `var prr = require('prr'); prr(...)`.

+# Worker Farm [](http://travis-ci.org/rvagg/node-worker-farm)
+
+[](https://nodei.co/npm/worker-farm/) [](https://nodei.co/npm/worker-farm/)
+
+
+Distribute processing tasks to child processes with an über-simple API and baked-in durability & custom concurrency options. *Available in npm as worker-farm*.
+
+## Example
+
+Given a file, *child.js*:
+
+```js
+module.exports = function (inp, callback) {
+ callback(null, inp + ' BAR (' + process.pid + ')')
+}
+```
+
+And a main file:
+
+```js
+var workerFarm = require('worker-farm')
+ , workers = workerFarm(require.resolve('./child'))
+ , ret = 0
+
+for (var i = 0; i < 10; i++) {
+ workers('#' + i + ' FOO', function (err, outp) {
+ console.log(outp)
+ if (++ret == 10)
+ workerFarm.end(workers)
+ })
+}
+```
+
+We'll get an output something like the following:
+
+```
+#1 FOO BAR (8546)
+#0 FOO BAR (8545)
+#8 FOO BAR (8545)
+#9 FOO BAR (8546)
+#2 FOO BAR (8548)
+#4 FOO BAR (8551)
+#3 FOO BAR (8549)
+#6 FOO BAR (8555)
+#5 FOO BAR (8553)
+#7 FOO BAR (8557)
+```
+
+This example is contained in the *[examples/basic](https://github.com/rvagg/node-worker-farm/tree/master/examples/basic/)* directory.
+
+### Example #1: Estimating π using child workers
+
+You will also find a more complex example in *[examples/pi](https://github.com/rvagg/node-worker-farm/tree/master/examples/pi/)* that estimates the value of **π** by using a Monte Carlo *area-under-the-curve* method and compares the speed of doing it all in-process vs using child workers to complete separate portions.
+
+Running `node examples/pi` will give you something like:
+
+```
+Doing it the slow (single-process) way...
+π ≈ 3.1416269360000006 (0.0000342824102075312 away from actual!)
+took 8341 milliseconds
+Doing it the fast (multi-process) way...
+π ≈ 3.1416233600000036 (0.00003070641021052367 away from actual!)
+took 1985 milliseconds
+```
+
+## Durability
+
+An important feature of Worker Farm is **call durability**. If a child process dies for any reason during the execution of call(s), those calls will be re-queued and taken care of by other child processes. In this way, when you ask for something to be done, unless there is something *seriously* wrong with what you're doing, you should get a result on your callback function.
+
+## My use-case
+
+There are other libraries for managing worker processes available but my use-case was fairly specific: I need to make heavy use of the [node-java](https://github.com/nearinfinity/node-java) library to interact with JVM code. Unfortunately, because the JVM garbage collector is so difficult to interact with, it's prone to killing your Node process when the GC kicks under heavy load. For safety I needed a durable way to make calls so that (1) it wouldn't kill my main process and (2) any calls that weren't successful would be resubmitted for processing.
+
+Worker Farm allows me to spin up multiple JVMs to be controlled by Node, and have a single, uncomplicated API that acts the same way as an in-process API and the calls will be taken care of by a child process even if an error kills a child process while it is working as the call will simply be passed to a new child process.
+
+**But**, don't think that Worker Farm is specific to that use-case, it's designed to be very generic and simple to adapt to anything requiring the use of child Node processes.
+
+## API
+
+Worker Farm exports a main function and an `end()` method. The main function sets up a "farm" of coordinated child-process workers and it can be used to instantiate multiple farms, all operating independently.
+
+### workerFarm([options, ]pathToModule[, exportedMethods])
+
+In its most basic form, you call `workerFarm()` with the path to a module file to be invoked by the child process. You should use an **absolute path** to the module file, the best way to obtain the path is with `require.resolve('./path/to/module')`, this function can be used in exactly the same way as `require('./path/to/module')` but it returns an absolute path.
+
+#### `exportedMethods`
+
+If your module exports a single function on `module.exports` then you should omit the final parameter. However, if you are exporting multiple functions on `module.exports` then you should list them in an Array of Strings:
+
+```js
+var workers = workerFarm(require.resolve('./mod'), [ 'doSomething', 'doSomethingElse' ])
+workers.doSomething(function () {})
+workers.doSomethingElse(function () {})
+```
+
+Listing the available methods will instruct Worker Farm what API to provide you with on the returned object. If you don't list a `exportedMethods` Array then you'll get a single callable function to use; but if you list the available methods then you'll get an object with callable functions by those names.
+
+**It is assumed that each function you call on your child module will take a `callback` function as the last argument.**
+
+#### `options`
+
+If you don't provide an `options` object then the following defaults will be used:
+
+```js
+{
+ workerOptions : {}
+ , maxCallsPerWorker : Infinity
+ , maxConcurrentWorkers : require('os').cpus().length
+ , maxConcurrentCallsPerWorker : 10
+ , maxConcurrentCalls : Infinity
+ , maxCallTime : Infinity
+ , maxRetries : Infinity
+ , autoStart : false
+}
+```
+
+ * **workerOptions** allows you to customize all the parameters passed to child nodes. This object supports [all possible options of `child_process.fork`](https://nodejs.org/api/child_process.html#child_process_child_process_fork_modulepath_args_options). The default options passed are the parent `execArgv`, `cwd` and `env`. Any (or all) of them can be overridden, and others can be added as well.
+
+ * **maxCallsPerWorker** allows you to control the lifespan of your child processes. A positive number will indicate that you only want each child to accept that many calls before it is terminated. This may be useful if you need to control memory leaks or similar in child processes.
+
+ * **maxConcurrentWorkers** will set the number of child processes to maintain concurrently. By default it is set to the number of CPUs available on the current system, but it can be any reasonable number, including `1`.
+
+ * **maxConcurrentCallsPerWorker** allows you to control the *concurrency* of individual child processes. Calls are placed into a queue and farmed out to child processes according to the number of calls they are allowed to handle concurrently. It is arbitrarily set to 10 by default so that calls are shared relatively evenly across workers, however if your calls predictably take a similar amount of time then you could set it to `Infinity` and Worker Farm won't queue any calls but spread them evenly across child processes and let them go at it. If your calls aren't I/O bound then it won't matter what value you use here as the individual workers won't be able to execute more than a single call at a time.
+
+ * **maxConcurrentCalls** allows you to control the maximum number of calls in the queue—either actively being processed or waiting for a worker to be processed. `Infinity` indicates no limit but if you have conditions that may endlessly queue jobs and you need to set a limit then provide a `>0` value and any calls that push the limit will return on their callback with a `MaxConcurrentCallsError` error (check `err.type == 'MaxConcurrentCallsError'`).
+
+ * **maxCallTime** *(use with caution, understand what this does before you use it!)* when `!== Infinity`, will cap a time, in milliseconds, that *any single call* can take to execute in a worker. If this time limit is exceeded by just a single call then the worker running that call will be killed and any calls running on that worker will have their callbacks returned with a `TimeoutError` (check `err.type == 'TimeoutError'`). If you are running with `maxConcurrentCallsPerWorker` value greater than `1` then **all calls currently executing** will fail and will be automatically resubmitted uless you've changed the `maxRetries` option. Use this if you have jobs that may potentially end in infinite loops that you can't programatically end with your child code. Preferably run this with a `maxConcurrentCallsPerWorker` so you don't interrupt other calls when you have a timeout. This timeout operates on a per-call basis but will interrupt a whole worker.
+
+ * **maxRetries** allows you to control the max number of call requeues after worker termination (unexpected or timeout). By default this option is set to `Infinity` which means that each call of each terminated worker will always be auto requeued. When the number of retries exceeds `maxRetries` value, the job callback will be executed with a `ProcessTerminatedError`. Note that if you are running with finite `maxCallTime` and `maxConcurrentCallsPerWorkers` greater than `1` then any `TimeoutError` will increase the retries counter *for each* concurrent call of the terminated worker.
+
+ * **autoStart** when set to `true` will start the workers as early as possible. Use this when your workers have to do expensive initialization. That way they'll be ready when the first request comes through.
+
+### workerFarm.end(farm)
+
+Child processes stay alive waiting for jobs indefinitely and your farm manager will stay alive managing its workers, so if you need it to stop then you have to do so explicitly. If you send your farm API to `workerFarm.end()` then it'll cleanly end your worker processes. Note though that it's a *soft* ending so it'll wait for child processes to finish what they are working on before asking them to die.
+
+Any calls that are queued and not yet being handled by a child process will be discarded. `end()` only waits for those currently in progress.
+
+Once you end a farm, it won't handle any more calls, so don't even try!
