README.md

node-jshint

A command line interface and npm package for jshint.

Install

To use jshint from any location (for npm v1.x) you need to install using the global (-g) flag.

npm install -g jshint

Usage

jshint -h

You can also require JSHint itself as a module.

var jshint = require('jshint');

Note: If you are using npm v1.x be sure to install jshint locally (without the -g flag) or link it globally.

Text Editor Plugins

  • gedit-node-jshint - Simply use CTRL+J in gedit to run JSHint using node-jshint.
  • vim syntastic - Run node-jshint at each file save.
  • sublime-jshint - F7 or command-B on any .js file. F4 next error line,column. shift-F4 previous error line,column.
  • eclipse-jshint - Run node-jshint at each file save. ## Custom Reporters

Specify a custom reporter module (see example/reporter.js).

--reporter path/to/reporter.js

Use a jslint compatible xml reporter.

--jslint-reporter

Show additional non-error data generated by jshint (unused globals etc).

--show-non-errors

Configuration Options

Note: This behavior described below is very different from versions prior to 0.6.

The CLI uses the default options that come with JSHint.

Only one extra option is unique to node-jshint: globals allows you to define an object of globals that get ignored for every file. To see an example you can look at how whitelisted globals are defined in the jshint code

To have your own configuration apply, there are several methods you can use:

Specify Manually

Setting the --config=/path/to/your/config command line option to specify your own configuration file outside of the directory tree for your project.

Within your Project's Directory Tree

When the CLI is called, and a configuration file isn't specified already, node-jshint will attempt to locate one for you starting in pwd. (or "present working directory") If this does not yield a .jshintrc file, it will move one level up (..) the directory tree all the way up to the filesystem root. If a file is found, it stops immediately and uses that set of configuration.

This setup allows you to set up one configuration file for your entire project. (place it in the root folder) As long as you run jshint from anywhere within your project directory tree, the same configuration file will be used.

Home Directory

If all the methods above do not yield a .jshintrc to use, the last place that will be checked is your user's $HOME directory.

File Extensions

Default extension for files is ".js". If you want to use JSHint with other file extensions (.json), you need to pass this extra extension as an option :

--extra-ext .json

Ignoring Files and Directories

If there is a .jshintignore file in your project's directory tree, (also provided you run jshint from within your project's directory) then any directories or files specified will be skipped over. (behaves just like a .gitignore file)

Note: Pattern matching uses minimatch, with the nocase option. When there is no match, it performs a left side match (when no forward slashes present and path is a directory).

Project Guidelines

  • All tests are passing.
  • No (new) JSHint errors are introduced.
