To install it, type:\n\n    $ npm install check-error\n\n### Browsers\n\nYou can also use it within the browser; install via npm and use the `check-error.js` file found within the download. For example:\n\n```html\n<script src=\"./node_modules/check-error/check-error.js\"></script>\n```\n\n## Usage\n\nThe primary export of `check-error` is an object which has the following methods:\n\n* `compatibleInstance(err, errorLike)` - Checks if an error is compatible with another `errorLike` object. If `errorLike` is an error instance we do a strict comparison, otherwise we return `false` by default, because instances of objects can only be compatible if they're both error instances.\n* `compatibleConstructor(err, errorLike)` - Checks if an error's constructor is compatible with another `errorLike` object. If `err` has the same constructor as `errorLike` or if `err` is an instance of `errorLike`.\n* `compatibleMessage(err, errMatcher)` - Checks if an error message is compatible with an `errMatcher` RegExp or String (we check if the message contains the String).\n* `getConstructorName(errorLike)` - Retrieves the name of a constructor, an error's constructor or `errorLike` itself if it's not an error instance or constructor.\n* `getMessage(err)` - Retrieves the message of an error or `err` itself if it's a String. If `err` or `err.message` is undefined we return an empty String.\n\n```js\nvar checkError = require('check-error');\n```\n\n#### .compatibleInstance(err, errorLike)\n\n```js\nvar checkError = require('check-error');\n\nvar funcThatThrows = function() { throw new TypeError('I am a TypeError') };\nvar caughtErr;\n\ntry {\n  funcThatThrows();\n} catch(e) {\n  caughtErr = e;\n}\n\nvar sameInstance = caughtErr;\n\ncheckError.compatibleInstance(caughtErr, sameInstance); // true\ncheckError.compatibleInstance(caughtErr, new TypeError('Another error')); // false\n```\n\n#### .compatibleConstructor(err, errorLike)\n\n```js\nvar checkError = require('check-error');\n\nvar funcThatThrows = function() { throw new TypeError('I am a TypeError') };\nvar caughtErr;\n\ntry {\n  funcThatThrows();\n} catch(e) {\n  caughtErr = e;\n}\n\ncheckError.compatibleConstructor(caughtErr, Error); // true\ncheckError.compatibleConstructor(caughtErr, TypeError); // true\ncheckError.compatibleConstructor(caughtErr, RangeError); // false\n```\n\n#### .compatibleMessage(err, errMatcher)\n\n```js\nvar checkError = require('check-error');\n\nvar funcThatThrows = function() { throw new TypeError('I am a TypeError') };\nvar caughtErr;\n\ntry {\n  funcThatThrows();\n} catch(e) {\n  caughtErr = e;\n}\n\nvar sameInstance = caughtErr;\n\ncheckError.compatibleMessage(caughtErr, /TypeError$/); // true\ncheckError.compatibleMessage(caughtErr, 'I am a'); // true\ncheckError.compatibleMessage(caughtErr, /unicorn/); // false\ncheckError.compatibleMessage(caughtErr, 'I do not exist'); // false\n```\n\n#### .getConstructorName(errorLike)\n\n```js\nvar checkError = require('check-error');\n\nvar funcThatThrows = function() { throw new TypeError('I am a TypeError') };\nvar caughtErr;\n\ntry {\n  funcThatThrows();\n} catch(e) {\n  caughtErr = e;\n}\n\nvar sameInstance = caughtErr;\n\ncheckError.getConstructorName(caughtErr) // 'TypeError'\n```\n\n#### .getMessage(err)\n\n```js\nvar checkError = require('check-error');\n\nvar funcThatThrows = function() { throw new TypeError('I am a TypeError') };\nvar caughtErr;\n\ntry {\n  funcThatThrows();\n} catch(e) {\n  caughtErr = e;\n}\n\nvar sameInstance = caughtErr;\n\ncheckError.getMessage(caughtErr) // 'I am a TypeError'\n```\n","maintainers":[{"name":"chaijs","email":"chaijs@keithcirkel.co.uk"}],"time":{"modified":"2022-06-13T05:55:31.487Z","created":"2016-06-03T15:32:19.225Z","1.0.0":"2016-06-03T15:32:19.225Z","1.0.1":"2016-06-07T09:22:16.414Z","1.0.2":"2016-06-27T21:13:56.593Z"},"homepage":"https://github.com/chaijs/check-error#readme","keywords":["check-error","error","chai util"],"repository":{"type":"git","url":"git+ssh://git@github.com/chaijs/check-error.git"},"contributors":[{"name":"David Losert","url":"https://github.com/davelosert"},{"name":"Keith Cirkel","url":"https://github.com/keithamus"},{"name":"Miroslav Bajtoš","url":"https://github.com/bajtos"},{"name":"Lucas Fernandes da Costa","url":"https://github.com/lucasfcosta"}],"author":{"name":"Jake Luer","email":"jake@alogicalparadox.com","url":"http://alogicalparadox.com"},"bugs":{"url":"https://github.com/chaijs/check-error/issues"},"license":"MIT","readmeFilename":"README.md","users":{"justjavac":true}}
