[6a3a178] | 1 | Browser-friendly inheritance fully compatible with standard node.js
|
---|
| 2 | [inherits](http://nodejs.org/api/util.html#util_util_inherits_constructor_superconstructor).
|
---|
| 3 |
|
---|
| 4 | This package exports standard `inherits` from node.js `util` module in
|
---|
| 5 | node environment, but also provides alternative browser-friendly
|
---|
| 6 | implementation through [browser
|
---|
| 7 | field](https://gist.github.com/shtylman/4339901). Alternative
|
---|
| 8 | implementation is a literal copy of standard one located in standalone
|
---|
| 9 | module to avoid requiring of `util`. It also has a shim for old
|
---|
| 10 | browsers with no `Object.create` support.
|
---|
| 11 |
|
---|
| 12 | While keeping you sure you are using standard `inherits`
|
---|
| 13 | implementation in node.js environment, it allows bundlers such as
|
---|
| 14 | [browserify](https://github.com/substack/node-browserify) to not
|
---|
| 15 | include full `util` package to your client code if all you need is
|
---|
| 16 | just `inherits` function. It worth, because browser shim for `util`
|
---|
| 17 | package is large and `inherits` is often the single function you need
|
---|
| 18 | from it.
|
---|
| 19 |
|
---|
| 20 | It's recommended to use this package instead of
|
---|
| 21 | `require('util').inherits` for any code that has chances to be used
|
---|
| 22 | not only in node.js but in browser too.
|
---|
| 23 |
|
---|
| 24 | ## usage
|
---|
| 25 |
|
---|
| 26 | ```js
|
---|
| 27 | var inherits = require('inherits');
|
---|
| 28 | // then use exactly as the standard one
|
---|
| 29 | ```
|
---|
| 30 |
|
---|
| 31 | ## note on version ~1.0
|
---|
| 32 |
|
---|
| 33 | Version ~1.0 had completely different motivation and is not compatible
|
---|
| 34 | neither with 2.0 nor with standard node.js `inherits`.
|
---|
| 35 |
|
---|
| 36 | If you are using version ~1.0 and planning to switch to ~2.0, be
|
---|
| 37 | careful:
|
---|
| 38 |
|
---|
| 39 | * new version uses `super_` instead of `super` for referencing
|
---|
| 40 | superclass
|
---|
| 41 | * new version overwrites current prototype while old one preserves any
|
---|
| 42 | existing fields on it
