# node-libs-browser

The node core libs for in-browser usage.

[![dependencies status](http://david-dm.org/webpack/node-libs-browser.png)](http://david-dm.org/webpack/node-libs-browser)

Exports a hash [object] of absolute paths to each lib, keyed by lib names. Modules without browser replacements are `null`.

Some modules have mocks in the `mock` directory. These are replacements with minimal functionality.

## Outdated versions 

### `buffer`

The current `buffer` implementation uses feross/buffer@4.x because feross/buffer@5.x relies on [typed arrays](https://github.com/feross/buffer/commit/5daca86b7cd5d2b8ccb167534d47421029f639e9#commitcomment-19698936).
This will be dropped as soon as IE9 is not a typical browser target anymore.

### `punycode`

The current `punycode` implementation uses bestiejs/punycode.js@1.x because bestiejs/punycode.js@2.x requires modern JS engines that understand `const` and `let`.
It will be removed someday since it has already been [deprecated from the node API](https://nodejs.org/api/punycode.html).
