Using the Theme Generator

While the theme generator can be run anywhere, it's happiest when it's run from an empty directory you'd like to become your theme.

While not a requirement we like to use NVM to manage the version of Node per project.

$3

Create a new directory. Example:

``bash
themes/custom/my_awesome_theme
`

$3

#### 1. Move into the new directory and install Node:

`bash
cd my_awesome_theme
`

`bash
nvm install 16 && node -v > .nvmrc
`

- This will install the latest release of NodeJS v16.

- It will create .nvmrc in the root of your project.

From now on, when working on this theme change into its directory and run nvm use and NVM will switch to the specified version for you.

#### 2. Install dependencies

`bash
npm install -g libnpx
`

#### 3. Generate the theme

Run the generator (Do not change this command):

`bash
npm create yo mc-d10-theme
`

- You should be taken through a series of questions that allow you to pick the best options for your theme.

IMPORTANT: Your theme's machine name should always match the directory name you created above.

More info if you're interested in how this stuff works:

npm create is an alias of npm init and uses npx under the hood. Find out more about npm init.

Note about Drupal 10

If you are building a Drupal 10 theme, make the following updates after your theme has been created:

- Remove node_modules

- Run npm install

About the New Theme

$3

This theme uses Twig namespaces. In order for these to work in Drupal you must install the Components Library module.

$3

The following is supported by your new theme.

- Storybook
- Component-Based Workflow
- ES6+ (With Source Maps)
- Sass
- Image Compression
- Live reloading
- Sass and JavaScript linting

$3

The theme generator allows you to (optionally) add editorial components.

- Accordion Group
- Card List
- Carousel
- Carousel Multi
- CTA
- Embed
- Form
- Gallery
- Hero
- Map
- Newsletter Form
- Promo Banner
- Quote
- Stats
- Side-by-Side
- Text Block
- Video Block

These can include both component and Drupal templates that are added to the appropriate place during theme generation. Your theme.libraries.yml is also updated to include the relevant libraries.

This can also be run within a pre-existing theme using:

`bash
npx yo mc-d10-theme:starter-kit
`

Create new Components

You can also generate base components with the right files in place using:

`bash
npm run generate
`

This is helpful if you are building out a new theme and would like to quickly create lots of new components with the libraries already wired up.

$3

TLDR: Don't do it if you can avoid it.

Optimally we want to gitignore all /.dist files and run npm run build as part of a continuous integration process.

$3

#### Supported Browsers

Change what browsers your theme supports by updating browserslist within package.json. For options take a look at browserslist.

This impacts CSS browser prefixes and JavaScript compiled files.

#### Demo Files

- Swap out screenshot.png with your own theme image.
- Remove or replace the font files in ./src/stories/global/fonts/.
- Change the colors in ./src/stories/global/colors/.

$3

Provided by default are seven npm scripts that point to Gulp tasks. We run gulp through npm scripts.

1. Run the default build task (gulp in this instance) and everything in it.
This is the equivalent to running gulp on the command line with Gulp installed globally.

`bash
npm run build
`

1. Compile Sass and JS.

`bash
npm run compile
`

1. Watch files and run tasks when they change.

`bash
npm run watch
`

1. Compress png and svg assets.

`bash
npm run compress
`

1. Build Storybook style guide.

`bash
npm run storybook
`

1. Lint Sass and JS files.

`bash
npm run lint
`

1. Delete compiled Sass, JS and style guide files from the /dist directory.

`bash
npm run clean
`

$3

`bash
git clone git@github.com:mediacurrent/theme_generator_10.git
`

`bash
cd theme_generator_10
`

Remove generator-mc-d10-theme if you have previously installed it:

_Tip: use npm ls -g -depth=0 to see what global node modules are installed._

`bash
npm uninstall generator-mc-d10-theme -g
`

Use the node version of the generator

`bash
nvm install

nvm use
`

Install the generator's dependencies

`bash
npm install
`

Link your local generator files to npm:

`bash
npm link
`

Now whenever you run yo mc-d10-theme` it'll use your locally cloned mc-d10-theme generator. Any updates done to the generator can be tested in real time.

Break off a feature branch dive right in. After you've got something you'd like to add, push back to the repo and pull request against develop.

$3

To test the changes you've made locally, ensure your new theme uses the same version of node as the generator.
