Integration with Flow
Flow is a static type checking system for JavaScript, developed by Facebook. Just a couple of weeks ago Flow became available on Windows and we’re happy to announce that you can now easily use Flow in WebStorm to analyse your code.
Set JavaScript version to Flow in Preferences | Languages & Frameworks | JavaScript and check that the path to your locally or globally installed Flow is set correctly in Preferences | Languages & Frameworks | JavaScript. That’s it!
Now all the files that begin with // @flow are going to be analysed with Flow and the errors are going to be reported right in the editor. If you change a file with a function definition, you don’t need to save it manually to trigger Flow to check its usages, it all works seamlessly.
PostCSS support
Good news for those using PostCSS – an official plugin for the PostCSS support is now available. You can install it via Preferences | Plugins – just search for PostCSS.
WebStorm now provides full-featured support for PostCSS with intelligent code completion, navigation, inspections, configurable code style and auto-formatting, as well as the Rename refactoring for custom selectors and media queries. Read more in the plugin description.
If you write PostCSS code in files with a .css extension, you will need to associate these files with PostCSS in Preferences | Languages & Frameworks | Stylesheets | Dialects to enable PostCSS support.
The following PostCSS plugins are supported: postcss-custom-properties, postcss-apply, postcss-custom-media, postcss-media-minmax, postcss-custom-selectors, postcss-nesting, and postcss-nested.
Smarter Rename for TypeScript
Rename refactoring in TypeScript now works through the inheritance hierarchy.
Now when you want to rename a method in a class, WebStorm will make sure that it’s also renamed in a parent class or in an interface. It also works the other way around: when renaming something in an interface or a parent class descendants are renamed as well.
In addition to that, Go to implementation… now works better for classes and interfaces.
More Angular CLI
Angular CLI commands that allow you to generate components, directives, services, and other blueprints are now available in Angular 2 projects (generated with Angular CLI) right in the New… popup (Cmd-N on OS X or Alt-Insert on Windows and Linux).
Grouped files in Project view
WebStorm now automatically displays generated files grouped with a source file located in the same folder in the Project view, for example, .css and .css.map files will be grouped with a .sass file with the same name. This will also work for some other patterns like .ts – .js – .js.map or .pug – .html.
Generate .editorconfig
You can now generate an .editorconfig file based on the current IDE code style settings. Go to Preferences | Editor | Code style – EditorConfig and hit Export – an .editorconfig file will added to the project root.
Spaces around arrow functions
With a new code style option you can configure adding spaces around arrow operator in JavaScript and TypeScript when reformatting the code or when using Convert to arrow function intention. Check Preferences | Editor | Code style | JavaScript – Spaces – Around operators.
