ucd-theme-tasks

CLI tool for base automation when compiling a UCD frontend.
This package contains all the CLI tasks needed by UCD frontend projects and themes. It is heavily dependent on Snowpack.

Extra Documentation

Installation

1. Require the ucd-theme-tasks package with node.js.

$ npm install ucd-theme-tasks --save-dev

1. Setup configuration files using the init command.

$ npx ucd-theme-tasks init

Upgrading from v3

https://github.com/ucdavis/ucd-theme-tasks/blob/master/docs/upgrade.md

Assumed File Structure

The default file structure assumes that this will be used in a tradition server rendered website such as a CMS like Drupal or Wordpress.

|-- dist/ (js and sass compiles here)
|-- js/
|   |-- main.js
|-- sass/
|   |-- style.scss
|-- package.json
|-- snowpack.config.js

It is also assumed that the site is already served in local development by a tool such as Docker or MAMP. Thus, doing ucd-theme-tasks dev --no-serve will not try to spin up its own server.
If doing a Single Page App (SPA) with a Javascript framework like Vue.js or React then the snowpack.config.js can have its mount changed to whatever suits it best. For reference in configuring a SPA see one of Snowpack's templates https://github.com/snowpackjs/snowpack/tree/main/create-snowpack-app.

CLI Commands

It is recommended to use the locally installed CLI via npx.

A .eslintrc.yml configuration file will be copied to the root of your project automatically when running the ucd-theme-tasks init command.

Sass/Scss Linting

Linting of Sass/Scss files is done via StyleLint.
A .stylelintrc.yml configuration file will be copied to the root of your project automatically when running the ucd-theme-tasks init command.

Configuration

Snowpack

Snowpack is used to compile all code and can be configured with the snowpack.config.js file. https://www.snowpack.dev/reference/configuration

Default Tasks

tasks-config.default.js contains all of the default configuration for controlling the tasks. This file can be referenced for all possible config options. Docs can be found at https://github.com/ucdavis/ucd-theme-tasks/blob/master/docs/config.md

Version 4 removed many of the old configuration options since Snowpack handles

them. Most of the configuration is now about path locations for syncing files across projects.

Pattern Lab

If you are using this package within Pattern Lab then it can build and watch patterns using ucd-theme-tasks patternLab.
