JSLint : how to use it?

I've understood that JSLint is a great tool for JavaScript development but I've some dark points in my global comprehension of this.

  1. How to use it inside my development environment ? In other words how and when do you run JSLint against your code ? I've seen the Aptana integration but it seems that it doesn't take into account statements like :

    /* jslint nomen: false */

  2. How to work correctly in a client side development environment ? I want JSLint to feel good when parsing calls including objects like "console", "$" or "JQuery".

  3. How to use it on a whole project with multiple files (with no import statement inside of them) ?

I've read to much statement suggesting to copy paste on jslint to sleep correctly, so any answer consisting of configuring the online JSLint form would be considered as irrelevant.

Some one came up with a solution to run it automatically on your project using node.js:

I'm sorry to write this answer which is not really one. The best solution I've found is to use JSHint which is a concurrent to JSLint with some nice extra features :

  • Installation is made easy through NPM with command like (also works for JSLint), NPM is required :

    npm install -g jshint

  • Execution is made easy against a lot of file (doesn't work for JSLint) :

    jshint mycodedirectory

  • Configuration is possible through the --config options, config files look like :

    {
  "curly":true,
  "eqeqeq": true,
  "immed": true,
  "bitwise": true,
  "newcap": true,
  "noempty": true,
  "unused": true,
  "camelcase":true,
  "undef": true,
  "strict": true,
  "trailing": true,
  "maxparams": 7,
  "maxdepth": 5,
  "maxstatements": 50,
  "maxcomplexity": 13
}

This solution works for both browser and server code, it's IDE and OS independent, it can be easily integrated in continuous integration process.

I use (a slightly modified) JSLINT for WSH on Emacs/WinXP. It highlights problematic code right while I am typing:

  • This is of great help not only to enforce the configured coding style, but also to find many JavaScript syntax errors before executing code.

  • It does respect statements such as /* jslint nomen: false */.

  • As you are asking concerning linting code that runs in a browser environment with jQuery, simply use standard JSLint options:

    /*jslint browser: true */
/*global $ */

Just be sure to replace the included JSLint code with the latest version.
