Angular 2 is a big upgrade from Angular 1. Now you need to know classes, TypeScript, modules, and on and on. Luckily WebStorm 2016.1 has kept up with all these changes and provides excellent support to help you navigate through all the new features. Come join us as John Lindquist, founder of, walks us through all the new features of WebStorm that can help make your transition to Angular 2 smooth as butter.

We believe that this webinar is going to be interesting for anyone interested in Angular 2 and TypeScript and working in WebStorm and other IntelliJ IDEA-based IDEs.

Code review in JavaScript projects

When was the last time you reviewed someone else’s code or had your own code reviewed? None of us write 100% bug-free code, none of us know absolutely everything, and everybody at some point has had to maintain some truly bewildering code.

Code review is a practice that helps developers help each other write better code, learn, share knowledge, and make maintaining code base easier. Performing regular code reviews in a team makes everybody better at what they do, and results in better software with fewer defects.

However, code review can also be a frustrating process – you’re used to all the power of your IDE, yet when you open up a set of changes in an average code review tool, you can’t leverage any of that. The cognitive load of having to navigate through the code in an unfamiliar way and losing all the context your IDE provides is one of the things that makes developers less keen to perform code reviews.

Luckily, there’s a tool that can help you with that: Upsource.


Upsource provides syntax highlighting for dozens of languages. Teams using JavaScript (including ECMAScript 6 and JSX), HTML and CSS and Java get an additional advantage: having an IntelliJ IDEA core together with its JavaScript support in it, Upsource provides server-side static code analysis just like in your IDE.

Let’s take a look at some Upsource features.

Angular 2 workflow in WebStorm

WebStorm is well-known for its AngularJS 1 support. WebStorm 2016.1 introduces lots of new exciting features in Angular 2 support. Combining that with support for the latest TypeScript and ECMAScript 6 (2015) features, WebStorm can be a great playground for your new Angular 2 applications.

If you’re using Angular 2 RC, please make sure you’re using WebStorm 2016.1.3 or WebStorm 2016.2 for proper support.

In this blog post we’d like to share with you some tips and tricks that we hope you’ll find useful when working on Angular 2 apps in TypeScript in WebStorm. We’ll have a look at:

Disclaimer: This blog post is not intended as a tutorial for getting started with Angular 2. If you’re new to Angular 2, we suggest you to go through the Angular 2 Quickstart first. While Angular 2 is still in Beta, there might be some changes in the framework that can affect the way Angular-specific coding assistance works in WebStorm.

Angular 2 and TypeScript support are also available in IntelliJ IDEA Ultimate, PhpStorm, PyCharm Professional, and RubyMine, all version 2016.1 or above. Make sure that you’ve installed AngularJS plugin: go to Preferences | Plugins – Install JetBrains plugins and search for AngularJS.

Let’s see what you can do with WebStorm!

Installing Angular 2

To make WebStorm understand Angular 2 syntax, we need to have Angular 2 library files in our project.

How to compile TypeScript in WebStorm

TypeScript is getting more and more popular recently, especially for Angular 2 projects.
To help you quickly get started with a new TypeScript project, WebStorm offers a built-in TypeScript compiler that you can use instead of configuring some other build tool. Let’s have a closer look at it!

Once you open a TypeScript file, WebStorm will suggest enabling its built-in TypeScript compiler to compile your code to JavaScript.


If you have a tsconfig.json file in your project, WebStorm will retrieve all the compiler options and project configuration from it and use them automatically.

You can configure the compiler behavior in Preferences | Languages & Frameworks | TypeScript.


For example, you can select Set options manually and specify the required compiling options as a command line arguments. These would then be used instead of the options in a tsconfig.json file (though we recommend using tsconfig.json).

Enabling source maps for debug

If you’d like to debug your TypeScript code using WebStorm or Chrome, make sure you add these two compiler options in the project tsconfig.json file:

"sourceMap": true,
"inlineSources": true

That way TypeScript compiler will generate source map file with inlined sources and when debugging the code the breakpoints set in the TypeScript code will be properly hit.

Using different version of TypeScript compiler

You can configure WebStorm to use a different version of the TypeScript compiler. To do so, click Edit… next to the compiler version in Preferences and specify a path to the TypeScript compiling service (lib folder in the TypeScript package with typescriptServices.js and lib.d.ts files).

Auto compilation on changes

There are two modes in which you can use a built-in TS compiler: it can either compile your code automatically as you write the code (check Track changes option), or you can trigger it manually with Compile All or Compile Current File actions. These actions are available via Find action popup (Cmd-Shift-A) or on the TypeScript Compiler tools window. Or you can assign them to the shortcut of your choice in Preferences | Keymap.


Any errors occurred during compilation would be shown in this tool window and also right in the editor (if you have enabled the Track changes compiler option). Double-click the error message to jump to the source code.

Tip: If you want to see errors from the compiler in the editor without automatically generating compiled files along the way, in your tsconfig.json file specify "compileOnSave": false. This option may be useful if you have some other build tool running the compilation.

Experimental: WebStorm 2016.2 adds experimental integration with the TypeScript internal service that provides code completion and analysis. It might provide more precise results and work faster compared to the WebStorm’s own coding assistance. At the same you will be able to benefit from WebStorm’s refactoring capabilities and more. You can enable that in Preferences | Languages & Frameworks | TypeScript.

Smart code completion for tsconfig.json

WebStorm 2016.1 has greatly improved coding assistance for the tsconfig.json file.
Press Alt-Enter or just start typing to get a list of all properties and their available options.


You can also create a new tsconfig.json file using a template via the New file popup (Cmd-N on OS X and Alt-Insert on Windows and Linux).
