## node-jslint



Easily use [JSLint][] from the command line.



      jslint bin/jslint.js



## What's New



Added latest jslint, 2018-01-27.



Version 0.12.0 contains the latest jslint-es6



See CHANGELOG.md for detailed change history



## Use the command-line client



### Install (both local and global are supported)



   npm i jslint



### Use the default jslint



    jslint lib/color.js



### Always use the latest jslint



    jslint --edition=latest lib/color.js



### Use a specific edition



For example, edition 2013-02-03 which shipped with node-jslint 0.1.9:



    jslint --edition=2013-02-03 lib/color.js



## Use node-jslint programmatically



### Streams interface



As of node-jslint 0.4.0, a streams interface is exposed.  You can use it in client code like this:



Install as a dependency:



    $ npm install --save jslint



Pull it into your code with require:



    var LintStream = require('jslint').LintStream;



Create and configure the stream linter:



    var options = {

        "edition": "latest",

        "length": 100

    },

        l = new LintStream(options);



Send files to the linter:



    var fileName, fileContents;

    l.write({file: fileName, body: fileContents});



Receive lint from the linter:



    l.on('data', function (chunk, encoding, callback) {

        // chunk is an object



        // chunk.file is whatever you supplied to write (see above)

        assert.deepEqual(chunk.file, fileName);



        // chunk.linted is an object holding the result from running JSLint

        // chunk.linted.ok is the boolean return code from JSLINT()

        // chunk.linted.errors is the array of errors, etc.

        // see JSLINT for the complete contents of the object



        callback();

    });



You can only pass options to the LintStream when creating it.  The `edition` option can be

used to select different editions of JSLint.



The LintStream is in object mode (objectMode: true).  It expects an

object with two properties: `file` and `body`.  The `file` property

can be used to pass metadata along with the file.  The `body` property

contains the file to be linted; it can be either a string or a Buffer.



The LintStream emits `'data'` events containing an object with two properties.

The `file` property is copied from the `file` property that is passed in.  The

`linted` property contains the results of running JSLINT.



### Simple interface



The simple interface provides an edition-aware loader.  This can be used as a frontend to

node-jslint's collection of editions of the JSLINT code.



    var node_jslint = require('jslint'),

        JSLINT = node_jslint.load(edition);



This exposes the same loading interface used in node-jslint, so it supports the special

edition names `default` and `latest` as well as date-based edition names such as `2013-08-26`



As of version 0.5.0, the `load` function also accepts filenames.  To be recognized as a filename,

the argument to load must contain a path-separator character (`/` or `\`) or end with the extension

`.js`.



## Usage examples



Multiple files



    jslint lib/color.js lib/reporter.js



All JSLint options supported



    jslint --white --vars --regexp lib/color.js



Defaults to true, but you can specify false



    jslint --bitwise false lib/color.js



Pass arrays



    jslint --predef $ --predef Backbone lib/color.js



JSLint your entire project



    jslint '**/*.js'



## Using JSLint with a config file



Start with the included `jslint.conf.example` file, name it `jslint.conf` and customize your options

per project or copy it to `$HOME/.jslint.conf` to apply your setting globally
