WebStorm 2017.3 EAP, 173.2463: multiple JavaScript versions in project, ESLint improvements

Please welcome the second EAP build of WebStorm 2017.3 (173.2463.22).

To get it, update via Toolbox App, or download it here and install side by side with your stable WebStorm version.


Download WebStorm 2017.3 EAP

We started the WebStorm 2017.3 Early Access Program last week. If you’ve missed the announcement, check out this blog post.

Here are the new features you can try in this week’s EAP build (173.2463.22).

Advanced import of ESLint code style rules

Previously, in WebStorm 2017.2, you could only import code style rules that were explicitly written in ESLint JSON configuration files.

Now, it’s also possible to apply rules from more complex configuration files written in JavaScript and YAML, as well as from configurations that use extends. To do so, use the action Apply ESLint code style rules, which is available in the context menu of the config file.

eslint-apply

WebStorm will send a special command to ESLint asking for a full summary of the applied rules in JSON. It will then parse the output and apply the rules to the IDE settings. You will see the list of applied rules in the IDE log.

eslint-log

Please note that this action requires ESLint to be installed in your project. It also means that the import won’t happen automatically, as it happens for the .eslintrc JSON configs.

New Emmet syntax for JSX

Now you can generate JSX tags with Emmet that will have text inside the tag or value in curly braces.

div{Title} will expand into the tag with the content Title, and div{{title}} will expand into the tag with title in the curly braces.

emmet-in-jsx

By the way, the tag{} syntax can also be very useful in HTML and other template files. Continue reading

WebStorm 2017.3 Early Access Preview: new and improved refactorings, better Vue.js support, new REST Client

Today we’re starting the Early Access Program for WebStorm 2017.3, the big update that will be released the end of November 2017.

Toolbox App is the easiest way to get the EAP builds. You can also subscribe to the EAP updates option in the IDE (Preferences | Appearance & Behavior | System Settings | Updates) and get notifications when a new build is available.


Download WebStorm 2017.3 EAP

If you’re not yet familiar with our Early Access Programs, here are some details:

  • Every week we publish a fresh build for the upcoming version of WebStorm.
  • EAP builds provide access to the newest features we’re currently developing.
  • EAP builds are free but expire 30 days after they’re built.
  • You can install an EAP build side-by-side with a stable WebStorm version.
  • We welcome your feedback in our issue tracker, youtrack.jetbrains.com/issues/WEB. Please don’t forget to mention the build number you’re using.

Important: WebStorm EAP builds are not fully tested and may be unstable.

WebStorm 2017.3 is going to bring many significant updates. Here are the highlights of what you can already try in this week’s EAP build (173.2290.2):

New and updated refactorings

Extract type alias in TypeScript

The new Extract type alias refactoring allows you to create an alias for a complex type.

Put the cursor on the type and call the Refactor this popup (Ctrl-T on macOS / Ctrl-Alt-Shift-T on Windows & Linux). Then select Extract Type Alias from the list and name the alias.

extract-type-alias

And if the type is used multiple times, the IDE will spot this and suggest automatically replacing all the instances with the new name. Continue reading

How to configure code completion in full-stack JavaScript projects?

If you’re working on a full-stack JavaScript application in WebStorm, you’ve probably noticed that code completion suggests some Node.js APIs in your client-side code and DOM APIs in the Node.js code. Here’s how to fix that.

What is Library in WebStorm?

All the objects defined in your application are automatically added to the WebStorm completion suggestions, but for adding Node.js and DOM APIs as well as symbols from the project’s dependencies to the code completion WebStorm uses a mechanism called External JavaScript Libraries or just Libraries.

You can see a list of Libraries configured for your project in Preferences | Languages & Frameworks | JavaScript | Libraries.

For every library, you can configure the scope where it works in the project. And that’s exactly what we need!

Configuring HTML and Node.js Core Libraries

The library called HTML contains all DOM APIs and by default is enabled for the whole project (hence the checked icon under Enabled). And so is the Node.js Core library with Node.js APIs (we enabled it before in Preferences | Languages & Frameworks | JavaScript | Node.js and npm).

html-node-libs

Uncheck HTML and Node.js Core libraries to disable them completely for now.

Now click on the Manage Scopes… button to start the configuration. Click + and select the folders with the client-side code – now select HTML library from the drop-down list next to them.

Click + again, select the folders or files with the server-side code and enable Node.js Core library for them.

manage-lib-scope

So now items from the HTML and Node.js Core libraries are resolved and shown in the code completion only in files in these specific project folders.

In the same way, we can configure the scope of the library that is automatically created for the node_modules folder.

For specific files, we can quickly manage the libraries with the Use JavaScript Libraries action in the file context menu in the editor. For example, we can enable Node.js Core library for our webpack configuration files.

enable-lib-for-file

By the way, the IDE inspections can be configured in a similar way using scopes in Preferences | Editor | Inspections.

WebStorm 2017.2 EAP, 172.3198: apply styles from ESLint, TypeScript type info

This week’s WebStorm 2017.2 EAP build (172.3198.20) is now available.

Now you can import some of the code style rules in ESLint configuration files to the IDE. In addition, we’ve improved how type info is shown in TypeScript and added an option to fold all one-line methods and functions in JavaScript and TypeScript.

You can install this WebStorm 2017.2 EAP build via Toolbox App or by downloading it on this page. It can be installed side-by-side with your stable WebStorm version. A patch update from the last week EAP build is also available.

Please share your feedback and report issues in our tracker. Thank you!

Import code style from ESLint configuration

WebStorm now allows you to import ESLint code style rules (we matched 37 ESLint rules) to the IDE’s JavaScript code style settings.

Now if you open an .eslintrc JSON file or package.json with the eslintConfig field, you’ll see the question “Apply code style from ESLint?” at the top of the editor. Click Yes to apply the matched rules to the Project code style scheme.
