NUSMods helps you find modules which fit your schedule, plan your ideal timetable, then share it with your friends or export it to various formats.

You will need Node.js and npm, which comes with Node.js.

$ npm install -g grunt
$ npm install
$ grunt coffee:tasks
$ grunt

On Windows, type grunt.cmd instead of grunt.

Start grunt to auto-build NUSMods as you work:

$ grunt watch

Grunt has been configured to watch files under src/ and tasks/ and compile / concatenate them whenever they change - you should not edit /css/*.css and /js/*.js directly.

If you made some changes but grunt watch was not running, compile them using:

$ grunt dev

This will invoke the coffee, less and concat tasks, which is equivalent to what grunt watch does.

If you are not already using some other web server, you can use Grunt's built-in static web server at http://localhost:8000/:

$ grunt server watch

Note: Grunt exits automatically when there are no more tasks to run, so the server task needs to prepended to a long-running task like watch.

To get a complete, minified, production build under dist/:

$ grunt

This invokes grunt's default task, which is equivalent to:

$ grunt download jsify dev clean mkdirs css min denull rev usemin html compress time

The download task automatically downloads the latest module information JSON file from http://nusmods.com/json/mod_info.json if it has been updated. It is executed by default when you run grunt's default task.

The file downloaded is identical to that generated by the crawl task. Crawling takes a considerable amount of time, so this lets you jump straight into development.

For development purposes, you should not need to do the crawling yourself unless you are working on the crawler itself.

To do a complete crawl:

$ grunt crawl

The crawl task caches every page retrieved, and compares the Correct as at timestamp to determine if it should retrieve a fresh set of pages.

It also forces a refresh for pages retrieved more than 2 days ago by default, which can be set by the crawl.maxCacheAge property in grunt.js:

crawl: {
  cachePath: 'cache',
  dest: 'json/mod_info.json',
  maxCacheAge: 2 * 86400 // in seconds
}

To manually force a refresh:

$ grunt crawl:refresh

Crawling NUS Bulletin information is disabled by default as it is not used in NUSMods currently, but to crawl with it enabled:

$ grunt crawl:nusBulletin

Note: This will take a long time.

• PHP for export and URL shortening scripts.
• YOURLS for URL shortening.
• wkhtmltopdf and wkhtmltoimage for pdf and image export. Using the static binaries is suggested, as compiling with all the features of the static build needs a custom patched version of QT, which takes a long time to build.
