Available in npm as *errno*. * [errno exposed](#errnoexposed) * [Custom errors](#customerrors) ## 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) return 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 heirachies 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 errno = require('errno') var MyError = errno.custom.createError('MyError') // inherits from Error var SpecificError = errno.custom.createError('SpecificError', MyError) // inherits from MyError var OtherError = errno.custom.createError('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. ## Contributors * [bahamas10](https://github.com/bahamas10) (Dave Eddy) - Added CLI ## Copyright & Licence *Copyright (c) 2012 [Rod Vagg](https://github.com/rvagg) ([@rvagg](https://twitter.com/rvagg))* Made available under the MIT licence: Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
