Learning Angular 2: Upgrading to Angular 2 RC5

Angular 2 , Angular 2 Learning , IntelliJ IDE No Comments »

Version 0.0.3 of my GuildRunner sandbox Angular 2 application is now available.  All of the differences between this version and the previous version (minus the updates to the version number and the README file) are changes made to upgrade the application to use Angular 2 RC5 (release candidate 5).

While there were some changes to the router/routing syntax, the biggest change that comes with RC5 is the introduction of Angular modules and the @ngModule decorator.  There is a long documentation page about Angular modules in the official developer guide, but essentially Angular modules allow you to bundle sets of shared injectable dependencies into a single file that provides those dependencies "downstream".


IntelliJ, Angular CLI, and Indexing

Angular CLI , IntelliJ IDE No Comments »

As I started working on my Angular CLI-managed Angular 2 project, I discovered that making code changes while Angular CLI was either serving my application or waiting to re-execute unit tests would cause my IntelliJ IDE to start re-indexing my project files.  Each indexing run took several minutes and during that time IntelliJ was slow to respond to my attempts to edit and interact with the code files.

I solved this performance issue by selecting the "Project Structure" / "Project Settings" menu item, selecting "Modules", and marking the following folders as "Excluded" on the "Source" tab:

  • dist
  • tmp
Those two folders are created and updated by Angular CLI automatically while testing and serving the application: there's no benefit in having the IDE index them.

Learning Angular 2: Creating My First Sandbox Web Application

Angular 2 , Angular 2 Learning , Angular CLI , IntelliJ IDE No Comments »

While there is still a lot out there for me to read regarding Angular 2, I tend to learn by coding and solving problems.  Even though there are a few aspects of Angular 2 that are in flux at this time (like forms), I feel that I can start writing an application without much fear that I'd have to go back and redo things because the API has changed.

So I've created my first "sandbox" Angular 2 application where I can practice writing Angular code and figure out ways to accomplish specific application tasks with Angular 2.  I'm going to keep a copy of the code up on GitHub and release milestones in my development so that I have a historical picture of the development and so I can potentially backtrack and create different solutions to a given problem.  Plus, it will allow anyone to pull down a tagged version on their own machine to look at the code.

My first sandbox is an application called "GuildRunner".  My plan is that it will be an application for managing a fictional collection of trade guilds, and so I can use it to exploring dealing with common application issues like authentication and authorization, data relationships, and searching.  But I wanted to start by simply creating the foundation for the application structure and getting it up and running.


IntelliJ 2016.2 and Angular 2 Support

Angular 2 , IntelliJ IDE 1 Comment »

I realized today that the latest update (version 2016.2) for my IDE of choice - IntelliJ IDEA (Ultimate version) - includes additional support for Angular 2:

  • A collection of live templates for Angular 2 files such as components and services.
  • A better understanding of template syntax.
  • The ability to create a new IntelliJ project via the Angular CLI tool.
So I downloaded and installed the update, but that alone wasn't sufficient to access these new features.  Turns out I had never installed the "AngularJS" plugin (I remember coming across it before, just hadn't installed it).

Once I installed that plugin and restarted IntelliJ, I could select File -> New -> Project from the menu tree, and "AngularJS" (for Angular 1 projects) and "Angular CLI" were new options listed under the "Static Web" project option.  I went ahead and chose "Angular CLI", and IntelliJ invoked the global install of Angular CLI on my laptop and executed the "ng-init" command to create the application structure and foundation files for a new Angular 2 project.

Inside the Angular project, I could create a new component using live templates by creating a new empty TypeScript file, hitting Control/Command-J to insert a live template, typing "ng2-component" until it was the selected template and hitting the Tab key.  The template then lets you tab through the update points in the template so you can enter the directive, template, and component names you want.

Very cool, but I think I would probably end up creating my components using Angular CLI from within the Terminal window in the IDE, because the CLI can generate the full set of files for a given component (the TypeScript file, the template HTML file, the CSS file, and the unit test file).  It also looks like the templates that contain code related to routing need updating.

Still, it's always nice when your IDE adds new features to making your coding a little easier.

Learning Angular 2: Tour of Heroes Tutorial, Lesson 6

The next lesson in the Tour of Heroes tutorial covers an important topic: routing.  I've been looking forward to this particular lesson because I was curious as to how routing would work given the new component-structured architecture.
