Liferay Theme Tasks Build Status

The liferay-theme-tasks module is intended for use with the yeoman generator for Liferay themes.

Available tasks


gulp build

The build task generates the base theme files, compiles sass into css, and zips all theme files into a .war file, ready to be deployed to a Liferay server.


gulp deploy

The deploy initially runs the build task, and once the .war file has been created it deploys to the specified local appserver.

If you want to deploy to a live site, use the --live flag to deploy to a remote server.

gulp deploy --live

Note that the specified server must have the server-manager-web plugin deployed. The --live flag will deploy to the remote server specified in the init task.

If you want to deploy to a different server without changing the default server specified in init, you may use the --url flag.

gulp deploy --live --url

You may also specify your login credentials using the -u/--username and -p/--password flags.

gulp deploy --live -u -p test

Note: the deploy --live task is not currently working for Liferay 7.0 as the server-manager-web plugin has not been migrated to work with OSGi.


gulp extend

The extend task is what allows you to specify what base theme you are extending from. By default, themes created with the theme generator will base off the styled theme.

You first are prompted if you want to extend a Base theme or Themelet, then you will be prompted for where you would like to search for modules. Globally installed npm modules will search npm modules that have been installed on your computer with the -g flag. Selecting npm registry will search for published modules on npm.

Once it gives you the options and you make your selection, it will add any selected modules to your package.json under dependencies and run npm install.


gulp kickstart

The kickstart task allows you to copy the css, images, js, and templates from another theme into the src directory of your own. This allows you to quickly get up and running with a production ready theme.

kickstart is similar to extend. The difference is that kickstarting from another theme is a one time inheritance, while extending from another theme is a dynamic inheritance that applies your src files on top of the base theme on every build.


gulp status

Displays what base theme/themelets your theme is extending.


gulp watch

The watch task allows you to see the changes you make to your theme without a full redeploy.

After invoking the watch task, every time you save any changes to a file in your theme it compiles (if applicable) and copies it directly to your appserver.


gulp init

Prompts user for local and remote appserver information used for deployment purposes (see deploy task).



To register the liferay-theme-tasks you must call the registerTasks method in your theme's gulpfile.js, gulp being the only required parameter.

var gulp = require('gulp');
var liferayThemeTasks = require('liferay-theme-tasks');
    gulp: gulp,



type: string
required: false

The name that will be given to the generated war file. The distName can also be a template which has access to the theme's package.json fields.

    distName: '${name}-${version}',
    gulp: gulp,
// my-theme-1.0.0

Note: in 7.0 changing the war file name will also affect the context path of the theme when using gulp deploy which can result in having multiple versions of your theme deployed at the same time.


type: gulp instance
required: true

A gulp instance for exposing liferay-theme-tasks.


type: function

Allows theme developers to hook and overwrite tasks/sub tasks.

var gulp = require('gulp');
var liferayThemeTasks = require('liferay-theme-tasks');
    gulp: gulp,
    hookFn: function(gulp) {
        gulp.hook('before:build:src', function(done) {
            // Fires before build:src task
        gulp.hook('after:build', function(done) {
            // Fires after build task
        gulp.task('build:base', function(done) {
            // Overwrites build:base task

Note: hook callback function must invoke done argument OR return a stream.


type: string
default: ./build

Determines the destination of built files.


type: string
default: ./dist

Determines the destination of the generated .war file.


type: string
default: ./src

Determines where theme source files are located. If set to anything other than default value, you must manually relocate all files in src directory to new location.


type: array

Specifies a list of PostCSS plugins to run on the compiled CSS after the SASS compilation


type: object

Whatever properties are set in sassOptions get passed to gulp-sass.


The liferayTheme object is located in a theme's package.json file and contains various options that relate to the gulp tasks.

    "name": "my-liferay-theme",
    "version": "1.0.0",
    "main": "package.json",
    "keywords": [
    "liferayTheme": {
        "baseTheme": "styled",
        "templateLanguage": "ftl",
        "version": "7.0"
    "devDependencies": {
        "gulp": "^3.8.10",
        "liferay-theme-deps-7.1": "*",
        "liferay-theme-tasks": "*"


Determines the base theme. This property is set by the extend task.


The name or names of npm modules. These modules must expose a function that follows the same pattern as a hookFn.

If a module is listed in hookModules, it must also be added to the devDependencies of the theme.


Determines the themelets that are implemented by this theme. This property is set by the extend task.


Version of Liferay Portal this theme is intended for.

Additional Theme Dependencies

In order for themes to successfully build, they must declare additional dependencies in their package.json file such as liferay-frontend-theme-unstyled and liferay-frontend-theme-styled.

These additional dependencies are normally included automatically in themes created with the Theme Generator.

If you would like to require specific versions of these dependencies, you can specify them directly in your theme's package.json file.




npm i liferay-theme-tasks
