# grunt-contrib-jst > Compile underscore templates to JST file (part of the [grunt-contrib](https://github.com/gruntjs/grunt-contrib) collection). Submitted by [Tim Branyen](/tbranyen). ## Getting Started Install this grunt plugin next to your project's [grunt.js gruntfile][getting_started] with: `npm install grunt-contrib-jst` Then add this line to your project's `grunt.js` gruntfile: ```javascript grunt.loadNpmTasks('grunt-contrib-jst'); ``` [grunt]: https://github.com/cowboy/grunt [getting_started]: https://github.com/cowboy/grunt/blob/master/docs/getting_started.md ### Overview This task compiles Underscore compatible templates into functions that can be concatenated and minified with existing source files. Inside your `grunt.js` file, add a section named `jst`. This section specifies the files to compile and the options passed to [underscore.template](http://underscorejs.org/#template). #### Parameters ##### files ```object``` This defines what files this task will process and should contain key:value pairs. The key (destination) should be an unique filepath (supports [grunt.template](https://github.com/cowboy/grunt/blob/master/docs/api_template.md)) and the value (source) should be a filepath or an array of filepaths (supports [minimatch](https://github.com/isaacs/minimatch)). Note: Values are precompiled to the namespaced JST array in the order passed. ##### options ```object``` This controls how this task (and its helpers) operate and should contain key:value pairs, see options below. #### Options ##### namespace ```string``` The namespace in which the resulting JST templates are assigned to. ##### templateSettings ```object``` The settings passed to underscore when compiling templates. #### Config Examples ``` javascript jst: { compile: { options: { templateSettings: { interpolate : /\{\{(.+?)\}\}/g } }, files: { "path/to/compiled/templates.js": ["path/to/source/**/*.html"] } } } ```
