lein-jslint

JSLint is a static code analysis tool used in software development for checking if JavaScript source code complies with coding rules.

lein-jslint is a Leiningen plugin for running javascript code through JSLint.

Pre-requirements

Install NodeJS and NPM (package manager for Node) to install JSHint:

• On Ubuntu: sudo apt-get install nodejs
• On Mac OS X: brew install node

Installation

Install JSLint to use lein-jslint plugin. It could be done in few ways:

• Use NPM to install JSLint globally: npm install jslint -g
• You can also install JSLint in the current directory: npm install jslint
• Use lein-npm plugin: lein npm install
• Use just Leiningen: lein deps

Setup

To enable lein-jslint for your project, put the following in the :plugins vector of your project.clj file:

; Use latest version instead of "X.X.X"
:plugins [[lein-jslint "X.X.X"]]

Configuration

You can specify places, where JS files will be located with: clojure :jslint { :includes ["resources/public/js/*.js" "resources/js/*.js"] }

You can also specify JS files that should be excluded from checking: clojure :jslint { :excludes ["resources/public/lib/*.js"] }

To specify :includes and :excludes options, it is possible to use Glob Patterns.

JSLint rules could be configured with :config parameter: clojure ; It specifies which JSLint options to turn on or off :jslint { :debug true ; To debug processing :config {:predef {"angular" "console" "$"} :nomen true :eqeq true ...}}

You can use both variants to specify keys: string values or keywords.

All available parameters are described in the official documentation here

Hooks

To enable this plugin in compile stage, use the following hook: clojure :hooks [lein-jslint.plugin]

Examples

Detailed example

:jslint {
  :includes ["resources/public/js/*.js"]

  ; This configuration is used by default
  :config {:confusion    true
           :continue     true
           :regexp       true
           :unparam      true
           :vars         true}}

Another example of configuration file: .jslintrc

Example project

Just clone the current repository and try to play with example project for better understanding how to use lein-jslint.
