NOTE: This library is deprecated and won't accept Pull Requests that include Breaking Changes or new Features. Only bugfixes are accepted. [![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. | lib name | browser implementation | mock implementation | | :-------------: | :-------------------------------------------------------------------------------------------: | :------------------------------------------------------------------------------------: | | assert | [defunctzombie/commonjs-assert](https://github.com/defunctzombie/commonjs-assert) | --- | | buffer | [feross/buffer](https://github.com/feross/buffer) | [buffer.js](https://github.com/webpack/node-libs-browser/blob/master/mock/buffer.js) | | child\_process | --- | --- | | cluster | --- | --- | | console | [Raynos/console-browserify](https://github.com/Raynos/console-browserify) | [console.js](https://github.com/webpack/node-libs-browser/blob/master/mock/console.js) | | constants | [juliangruber/constants-browserify](https://github.com/juliangruber/constants-browserify) | --- | | crypto | [crypto-browserify/crypto-browserify](https://github.com/crypto-browserify/crypto-browserify) | --- | | dgram | --- | --- | | dns | --- | [dns.js](https://github.com/webpack/node-libs-browser/blob/master/mock/dns.js) | | domain | [bevry/domain-browser](https://github.com/bevry/domain-browser) | --- | | events | [Gozala/events](https://github.com/Gozala/events) | --- | | fs | --- | --- | | http | [jhiesey/stream-http](https://github.com/jhiesey/stream-http) | --- | | https | [substack/https-browserify](https://github.com/substack/https-browserify) | --- | | module | --- | --- | | net | --- | [net.js](https://github.com/webpack/node-libs-browser/blob/master/mock/net.js) | | os | [CoderPuppy/os-browserify](https://github.com/CoderPuppy/os-browserify) | --- | | path | [substack/path-browserify](https://github.com/substack/path-browserify) | --- | | process | [shtylman/node-process](https://github.com/shtylman/node-process) | [process.js](https://github.com/webpack/node-libs-browser/blob/master/mock/process.js) | | punycode | [bestiejs/punycode.js](https://github.com/bestiejs/punycode.js) | --- | | querystring | [mike-spainhower/querystring](https://github.com/mike-spainhower/querystring) | --- | | readline | --- | --- | | repl | --- | --- | | stream | [substack/stream-browserify](https://github.com/substack/stream-browserify) | --- | | string\_decoder | [rvagg/string\_decoder](https://github.com/rvagg/string_decoder) | --- | | sys | [defunctzombie/node-util](https://github.com/defunctzombie/node-util) | --- | | timers | [jryans/timers-browserify](https://github.com/jryans/timers-browserify) | --- | | tls | --- | [tls.js](https://github.com/webpack/node-libs-browser/blob/master/mock/tls.js) | | tty | [substack/tty-browserify](https://github.com/substack/tty-browserify) | [tty.js](https://github.com/webpack/node-libs-browser/blob/master/mock/tty.js) | | url | [defunctzombie/node-url](https://github.com/defunctzombie/node-url) | --- | | util | [defunctzombie/node-util](https://github.com/defunctzombie/node-util) | --- | | vm | [substack/vm-browserify](https://github.com/substack/vm-browserify) | --- | | zlib | [devongovett/browserify-zlib](https://github.com/devongovett/browserify-zlib) | --- | ## 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. because bestiejs/punycode. 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). ## License MIT --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://bryan-guner.gitbook.io/my-docs/redux/repos/examples/real-world/node_modules/node-libs-browser.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
