A JSLint server for more expedient linting.

lintnode - a JSLint server for more expedient linting

I was setting up flymake-mode_ with JSLint_, and thinking it was pretty great, but that rhino start-up cost is pretty big for a flymake application. If we just kept JSLint running, wouldn't that be a lot faster?

Then I caught a talk on the node.js_ server, and saw a way.

In my environment, this cuts jslint invocation time in half.

This project also depends on the Express_ framework, with the underscore and haml packages. I recommend installation with npm_ to manage these dependencies.

The jslint.curl script depends on curl, but you can easily reproduce it with any other http client.

.. _flymake-mode: .. _JSLint: .. _node.js: .. _Express: .. _npm:


$ node lintnode/app.js --port 3003 & Express started at http://localhost:3003/ in development mode

$ lintnode/jslint.curl myfilthycode.js

The exit code of jslint.curl is currently not nearly as relevant as the output on standard out. The output should be fully compatible with JSLint's Rhino version__.

.. __:

See the included flymake-jslint.el__.

.. __: flymake-jslint.el

jslint_port may be passed on the node command line with the --port parameter. It defaults to 3003.

jstlint_options can be configured by passing the --exclude option to app.js. e.g.

$ node app.js --exclude nomen,undef


$ node app.js --set maxlen:80,node

Alternatively they can be configured within emacs by setting the variable lintnode-jslint-excludes

For documentation on JSLint's options, see JSLint options_.
