# Brunch The Brunch task will run your automated frontend tasks. It lives under the `brunch` namespace and has following configurable parameters: ```yaml # grumphp.yml grumphp: tasks: brunch: task: build env: production jobs: 4 debug: false triggered_by: [js, jsx, coffee, ts, less, sass, scss] ``` **task** *Default: build* This option specifies which Brunch task you want to run. This option is set to `build` by default. This means that brunch will run the `build` task. Note that this task should be used to compile your assets. It is also possible to alter code during commit, but this is surely **NOT** recommended! **env** *Default: production* This option specifies in which format you want to compile your assets. E.g: `--env production`. You can specify the env you set up in your brunch config file. **jobs** *Default: 4* This option enables experimental multi-process support. May improve compilation speed of large projects. Try different WORKERS amount to see which one works best for your system. **debug** *Default: false* It enables verbose debug output. **triggered_by** *Default: [js, jsx, coffee, ts, less, sass, scss]* This option will specify which file extensions will trigger the brunch task. By default Brunch will be triggered by altering a front-end file. You can overwrite this option to whatever file you want to use!
