SMC's Liferay Theme Hooks

liferay-theme-hooks offers some packages that are meant to be used in combination with Liferay Theme Tasks in order to make working on a Liferay theme a more modern and pleasurable experience.

In particular we let developers

• write modern CSS and automatically add vendor prefixes through Autoprefixer,
• write modern JavaScript and automatically transpile them with Babel.

These hooks are run for you when the build or deploy tasks are run.

Installation

After you created your theme (for example with the Liferay Theme Generator) you can add our hooks by installing them inside your root folder:

cd my-awesome-theme
# With npm:
npm install --save-dev @smclab/liferay-theme-autoprefixer-hook
npm install --save-dev @smclab/liferay-theme-babel-hook
# Or alternatively with Yarn:
yarn add --dev @smclab/liferay-theme-autoprefixer-hook
yarn add --dev @smclab/liferay-theme-babel-hook

After installing the desired hook add the following to your liferay theme's package.json

{
  "name": "my-awesome-theme",
  // ...the rest of your package.json...
  "liferayTheme": {
    "hookModules": [
      // Here you can choose which hook to keep
      "@smclab/liferay-theme-autoprefixer-hook",
      "@smclab/liferay-theme-babel-hook"
    ]
  }
}

Configuring supported browsers

Both hooks let you specify a list of browsers your project needs to support. The list of features that need to be transpiled/autoprefixed will be automatically retrived so that you can focus on the important stuff!

For doing this we use Browserslist.

The list of browsers you want your theme to support can be defined in the package.json or in a .browserslistrc file in your theme's root direcotry.

If you want, for example, to support all the supported browsers supported by Liferay you can use the following file .browserslistrc

last 1 Chrome versions
last 1 Firefox versions
last 1 Edge versions
ie 9
ie 10
Safari 8
Safari 10

or you can add the following to you liferay theme's package.json

{
  "name": "my-awesome-theme",
  // ...the rest of your package.json...
  "browserslist": {
    "browsers": [
      "last 1 Chrome versions",
      "last 1 Firefox versions",
      "last 1 Edge versions",
      "ie 9",
      "ie 10",
      "Safari 8",
      "Safari 10"
    ],
    "cascade": false
  }
}
