How to Create an Angular 2.0 Application in Liferay DXP to Fetch the OOTB Advantages?
Intro
There have been years since technology has been instigating innovations forthe civilizations. That’s what we have been relating to something calleddevelopment. And we are now in a century where technology has reached toan extent with such inventions that were unthinkable before. Virtual Realityfor instance is one of the aspects in this case. This is the science which dealswith the facets that actually do not exist!
AngularJS had already been much popular among developers and enhancements of Angular 2.0 have made it even more preferred to create speedy, rich and effective applications. As we know, Angular 2.0 also requires third party tools to leverage security features, Authorization/Authentication etc. With its OOTB functionalities, Liferay DXP can be proved an ideal solution to be used with Angular 2.0 because of many reasons. Few are listed below:
• Liferay comes with more powerful security features as portal setup in terms of creating SPA website using Angular
• Authorization/Authentication will be managed by Liferay, no need to consider that part in Angular
• You can use any RESTful API to load data
• Write RESTful API in portlet and utilize it in angular services to serve CRUD data operations
In this blog, step by step we will create a simple “Hello World” Angular 2.0 App in Liferay DXP Theme. We have classified the blog in three easy steps for simplified understanding.
Prerequisite
• Creation of Liferay theme
• Adding Angular files to Liferay theme
Prerequisite:
• You need to have the basic idea about creating a simple Angular application
• If you are too new to Angular, please find the basic understanding https://angular.io/docs/js/latest/quickstart.html
• You need to have primary knowledge about creating a theme for LiferayDXP
If you are not familiar with Liferay theme creation, pleasefind the primary knowledge at Step by Step Guide to Create Theme for Liferay DXP.
Once you are ready with essential information, we are ready to start our actual work.
Creation of Liferay theme
Create new Liferay Theme “hello-world-theme” and deploy it
• Create blank website “my-website” and create a public page “home”.• Apply newly created “hello-world-theme” to “home” page.• If you observe your code, you will have following structure for your newly
created “hello-world-theme”:
Adding Angular to Liferay theme
1. Now, let’s add Angular files to Liferay theme
• Create new folder “templates” in “src” folder.
• Go to “build” folder and copy “portal_normal.ftl” file and place it in src > templates folder.
Your “src” folder will look like image shown below.
2. Load Node Modules for Angular dependencies
• Go to your “src” folder and create “package.json” file. Paste following code:
• If you want to use latest packages, go to Angular.io, and grab latest package.json file. Go to directory D:\ws\themes\hello-world-theme\src in CMD and run command “npm install”
Now you able to see “node_modules” folder created inside “src” folder.
You have all dependent modules installed in your theme > src > node_modulesfolder.
• 3. Create “App” folder inside “src” folder and create two files app.component.js and app.module.js.
And put below code in app.module.js file:
4. Now we have some files in “App” and “node_modules” folder and the complexity is how to call files from the folders because by default Liferayprovides access only to CSS, JS and Images folder.
• As a solution, we have to create freemarker variables to load files from “App” and “node_modules” folder.
• Open “portal_normal.ftl” from “templates” folder and put below code inside <head> section.
Now we have ${appPath} and ${nodeModules} path available to access files inside these folders.
5. Load libraries and app files into theme. Search for <!– inject:js–><!–endinject –>text in portal_normal.ftl.
• Put the below given code between <!– inject:js–><!– endinject –> comments.
• You will be able to see the files being loaded from ${nodeModules} and ${appPath}folder.
6. It is time to load your angular app now
• Go to <section id=”content”> in portal_normal.ftl and then insert <my-app>Loading…</my-app>
If you observe, your complete portal_normal.ftl code will look as shown below.
Once all above actions are completed, it’s time to build theme and run your App.
• “build” your theme
• “deploy” your theme
• Refresh your browser
And that’s done. Your first Angular 2.0 App in Liferay DXP is ready now.
