If your code runs in Node.js, `util` is built in. If your code runs in the browser, bundlers like [browserify](https://github.com/browserify/browserify) or [webpack](https://github.com/webpack/webpack) also include the `util` module. - -But if none of those apply, with npm do: - -```shell -npm install util -``` - -## Usage - -```javascript -var util = require('util') -var EventEmitter = require('events') - -function MyClass() { EventEmitter.call(this) } -util.inherits(MyClass, EventEmitter) -``` - -## Browser Support - -The `util` module uses ES5 features. If you need to support very old browsers like IE8, use a shim like [`es5-shim`](https://www.npmjs.com/package/es5-shim). You need both the shim and the sham versions of `es5-shim`. - -To use `util.promisify` and `util.callbackify`, Promises must already be available. If you need to support browsers like IE11 that do not support Promises, use a shim. [es6-promise](https://github.com/stefanpenner/es6-promise) is a popular one but there are many others available on npm. - -## API - -See the [Node.js util docs][util]. `util` currently supports the Node 8 LTS API. However, some of the methods are outdated. The `inspect` and `format` methods included in this module are a lot more simple and barebones than the ones in Node.js. - -## Contributing - -PRs are very welcome! The main way to contribute to `util` is by porting features, bugfixes and tests from Node.js. Ideally, code contributions to this module are copy-pasted from Node.js and transpiled to ES5, rather than reimplemented from scratch. Matching the Node.js code as closely as possible makes maintenance simpler when new changes land in Node.js. -This module intends to provide exactly the same API as Node.js, so features that are not available in the core `util` module will not be accepted. Feature requests should instead be directed at [nodejs/node](https://github.com/nodejs/node) and will be added to this module once they are implemented in Node.js. - -If there is a difference in behaviour between Node.js's `util` module and this module, please open an issue! - -## License - -[MIT](./LICENSE) - -[util]: https://nodejs.org/docs/latest-v8.x/api/util.html diff --git a/node_modules/util/package.json b/node_modules/util/package.json deleted file mode 100644 index bda8ea0..0000000 --- a/node_modules/util/package.json +++ /dev/null @@ -1,67 +0,0 @@ -{ - "_from": "util@^0.11.0", - "_id": "util@0.11.1", - "_inBundle": false, - "_integrity": "sha512-HShAsny+zS2TZfaXxD9tYj4HQGlBezXZMZuM/S5PKLLoZkShZiGk9o5CzukI1LVHZvjdvZ2Sj1aW/Ndn2NB/HQ==", - "_location": "/util", - "_phantomChildren": {}, - "_requested": { - "type": "range", - "registry": true, - "raw": "util@^0.11.0", - "name": "util", - "escapedName": "util", - "rawSpec": "^0.11.0", - "saveSpec": null, - "fetchSpec": "^0.11.0" - }, - "_requiredBy": [ - "/node-libs-browser" - ], - "_resolved": "https://registry.npmjs.org/util/-/util-0.11.1.tgz", - "_shasum": "3236733720ec64bb27f6e26f421aaa2e1b588d61", - "_spec": "util@^0.11.0", - "_where": "/home/pruss/Dev/3-minute-website/node_modules/node-libs-browser", - "author": { - "name": "Joyent", - "url": "http://www.joyent.com" - }, - "browser": { - "./support/isBuffer.js": "./support/isBufferBrowser.js" - }, - "bugs": { - "url": "https://github.com/defunctzombie/node-util/issues" - }, - "bundleDependencies": false, - "dependencies": { - "inherits": "2.0.3" - }, - "deprecated": false, - "description": "Node.JS util module", - "devDependencies": { - "airtap": "~0.1.0", - "is-async-supported": "~1.2.0", - "run-series": "~1.1.4", - "tape": "~4.9.0" - }, - "files": [ - "util.js", - "support" - ], - "homepage": "https://github.com/defunctzombie/node-util", - "keywords": [ - "util" - ], - "license": "MIT", - "main": "./util.js", - "name": "util", - "repository": { - "type": "git", - "url": "git://github.com/defunctzombie/node-util.git" - }, - "scripts": { - "test": "node test/node/index.js", - "test:browsers": "airtap test/browser/index.js" - }, - "version": "0.11.1" -} diff --git a/node_modules/util/support/isBuffer.js b/node_modules/util/support/isBuffer.js deleted file mode 100644 index ace9ac0..0000000 --- a/node_modules/util/support/isBuffer.js +++ /dev/null @@ -1,3 +0,0 @@ -module.exports = function isBuffer(arg) { - return arg instanceof Buffer; -} diff --git a/node_modules/util/support/isBufferBrowser.js b/node_modules/util/support/isBufferBrowser.js deleted file mode 100644 index 0e1bee1..0000000 --- a/node_modules/util/support/isBufferBrowser.js +++ /dev/null @@ -1,6 +0,0 @@ -module.exports = function isBuffer(arg) { - return arg && typeof arg === 'object' - && typeof arg.copy === 'function' - && typeof arg.fill === 'function' - && typeof arg.readUInt8 === 'function'; -}
