WebStorm 2017.1 Early Access Preview

Ekaterina Prigara

Today we start the Early Access Preview for WebStorm 2017.1 (EAP). Download WebStorm 2017.1 EAP, build 171.1834.8, here and install it side by side with your current stable WebStorm. No active subscription is required.

Since we released WebStorm 2016.3 a month ago, we’ve mostly focused on fixes, but also managed to add some new features in WebStorm 2017.1 EAP. Many more are coming after the holiday season. Stay tuned!

Better testing experience

Now it’s even easier to run Mocha tests with the new Run icon on the gutter. Click on an icon next to the test or the suit name and select Run or Debug.

Once you’ve run the tests, the icon will show their status – green circles for passed tests, red for failed ones. The run and debug actions will be still available on a click.

You can also re-run tests automatically on changes. To do so, click the Toggle auto-test icon on the left-hand side of the test tool window. You will see how their status changes in the editor, even if you have previously hidden the tool window. This will work both for Mocha and Karma.

Don’t forget that you can also run Mocha tests with a shortcut: place the caret on a test or a suit name and press Ctrl-Shift-R on macOS or Ctrl+Shift+F10 on Windows & Linux.

The new Go to test action (Shift-Cmd-T on macOS or Ctrl+Shift+T on Windows & Linux) lets you quickly navigate from a file to a related test file that follows popular naming conventions, e.g. has a .test., .spec. or _spec. suffix and is located either next to a file or in a test folder.

Integration with the Angular language service

WebStorm adds integration with the Angular language service, developed by the Angular team to improve code analysis and completion for Angular-TypeScript projects.

To enable the service, first, run the following in your project root:

npm install @angular/language-service --save-dev

Important: Due to some limitations of the service, please use it with Angular 2.3.1 or higher and with TypeScript 2.0.10.

WebStorm will start the service together with the TypeScript service. You’ll see all the errors and warnings in your TypeScript and HTML files not only in the editor, but also in the TypeScript tool window.

WebStorm will also add the results provided by the Angular service to code completion, wherever possible. All refactorings are powered by WebStorm.

Faster start with linters

WebStorm has integration with many popular linting tools that allows you to see the errors and warnings from these linters right in the editor.

Now when you open a new project that uses ESLint, TSLint, JSCS, or Stylelint (has it listed in package.json or has a related config file), error highlighting will be enabled automatically. You can always disable that (or enable for your existing project) in Preferences – just search for the name of the linter to get to the right configuration page.

Other noticeable features include:

• Support for emoji in the editor (rendered as color images on macOS and as monochrome characters on Windows and Linux)
• Zero-latency typing is now enabled by default
• Support for do expressions ECMAScript proposal
• WebStorm for Windows now comes with a bundled 64 bit JKD
