What’s new in WebStorm

WebStorm 2019.3 comes with 20% faster startup, major enhancements in Vue.js support, even smarter code completion for JavaScript and TypeScript, and a lot of lingering bugs fixed.

Performance

Faster startup

Faster startup

So far, one of the most common performance problems faced by WebStorm users has been the sluggish startup of the IDE. In the last two release cycles, we have devoted a lot of effort to reducing the time that users have had to wait for the welcome screen to show and for the IDE to open projects that are already indexed. As a result, you can now expect WebStorm to handle this 20% faster than previous versions.

Frameworks & Tools

Vue completion for separate files

More advanced code completion for Vue.js

To help you increase the speed of your coding, WebStorm can now autocomplete slot names for you. This works for the slot names defined in the project components and component libraries such as Vuetify, Quasar, and BootstrapVue.

Plus, WebStorm now understands the link between parts of the component located in separate files and delivers accurate completion suggestions for props, data, and methods not defined in a single .vue file.

Quick documentation in Vue.js projects

Quick documentation in Vue.js projects

With WebStorm 2019.3, you can now check out documentation for components and directives defined in Vue.js and some popular component libraries. For this, simply press F1 on the name of a component or directive in your code.

Support for the latest versions of popular technologies

WebStorm 2019.3 comes with support for schematics with Angular 9 and the Plug’n’Play feature from Yarn 2. Plus, it can help you work with key TypeScript 3.7 features: optional chaining, nullish coalescing, and assertion signatures.

Better support for props in React components

For components without propTypes, WebStorm will no longer report an unresolved property for props.something in the component definition if it sees that props are passed in the component usage.

JavaScript & TypeScript

Template language injections

Template language injections

Need to work with a code fragment in a language different from the main language of the file? You can now inject such code fragments into your files, including Pug, Handlebars, and EJS, by pressing Alt-Enter.

Name suggestions for new symbols

Name suggestions for new symbols

As you add new variable and parameter names in JavaScript or TypeScript files, you’ll now get name suggestions based on the names of classes, interfaces, and type aliases defined in the project, standard libraries, and dependencies you’re using.

For new variables, functions, classes, and interfaces, you’ll also get suggestions for names that were already used in the same scope but haven’t yet been defined and are marked as unresolved.

HTML & Style Sheets

Completion for CSS libraries on CDN

Completion for CSS libraries on CDN

If you’re using Bootstrap or another CSS library in your project and you have it linked from a CDN in your HTML file, you can now get completion for the class names from that library, without adding its sources to the project. To enable this, simply press Alt-Enter on the link in the HTML file and select Download library.

Version Control

Reworked UI for cloning projects

Reworked UI for cloning projects

When you clone a project from a version control system, you’ll now see an updated Get from Version Control dialog shown on the welcome screen and the VCS menu.

With this redesign, we mainly wanted to improve the experience of getting projects from GitHub: you can now log in to your GitHub account right from the updated dialog. Once you’ve logged in, you can explore the list of repositories in your account and the organizations you belong to and clone projects to WebStorm right from there.

Pushing changes from any branch

Need to push changes from one branch while working with the other? With the latest update, you no longer need to switch to the branch you want to push changes from – simply select it from the Branches popup and hit Push.

A more streamlined commit process

Now you can make commits right from the Version Control tool window – a separate dialog won’t block the rest of the IDE. For this, tick Commit from the Local Changes without showing a dialog in Preferences/Settings | Version Control | Commit Dialog.

New actions for checking out branches

To resolve a number of usability issues, we replaced a single Checkout as... action with two new ones: a unified Checkout action for remote branches and the New Branch from Selected... action for both remote and local branches.

IDE

Run anything action

New action for running tools and configurations

Need to launch tools like npm and Yarn, open recent projects, or start a run/debug configuration? You can now do it all from one place using the Run Anything action (Ctrl-Ctrl).

Searching in the selection only

Searching in the selection only

With the new In Selection filter (Cmd/Ctrl-F twice), you can find specific pieces of information faster by narrowing down your searches to the selected parts of code in a file.

Unbundling Dart support

Starting with WebStorm 2019.3, the Dart plugin will no longer be bundled. This was done to shorten the release cycles for it – bundled plugins can only be updated together with an update of the entire IDE. So, if you use Dart, you’ll now need to install the same Dart plugin from Preferences/Settings | Plugins.

Enabling global file watchers by default

If you’re using a third-party tool like Prettier for a project and have it configured via a file watcher, it’s likely you may want this configuration to be automatically applied to all the new projects you create. Now you can achieve this by enabling global file watchers by default.

JavaScript & TypeScript

New UI of completion popup

New UI of completion popup

The completion popup got a new, more polished look.

The presentation of completion suggestions in JavaScript and TypeScript became clearer and more consistent. It’s now easier to spot where the symbol is defined and whether it’s part of a standard language API. There’s also a new icon for symbols with multiple definitions.

Smart new intentions

Smart new intentions

With the new Propagate to destructuring intention (Alt-Enter), you can replace an extra variable if it’s possible with another destructuring. To remove a destructuring completely, use the intention action called Replace destructuring with property or index access.

The IDE will now warn you if a boolean expression in a condition has some unnecessary parts and will suggest simplifying it.

Improved Rename refactoring

Improved Rename refactoring

When you rename a symbol in a JavaScript or TypeScript file, the IDE now groups together dynamic usages and, by default, excludes them from the refactoring. This makes the refactoring more accurate and gives you more control over what exactly should be renamed in the Refactoring Preview tool window.

Vue.js

Better support for Vue.js

Better support for Vue.js component libraries

Using Vuetify, BootstrapVue, or Quasar in your Vue.js application? Code completion for components and their props from these and some other Vue component libraries is now more precise. This was made possible by a new approach we’ve adopted to work with these libraries in the IDE.

Code Editing

Syntax highlighting for 20+ languages

Syntax highlighting for 20+ languages

Need to occasionally look through some PHP or Python files in WebStorm? Syntax highlighting is now available for these and many other languages – with no additional configuration required, thanks to the collection of TextMate grammar files that ships with the IDE.

Completion for mistyped keywords and names

Completion for mistyped keywords and names

Ever typed funtcion or fnction instead of function by mistake? Now, code completion can understand this kind of errors and will still suggest the most relevant option for you. This works in all supported languages and for all symbols – keywords, classes, functions, components, and so on.

Support for shell scripts

Support for shell scripts

WebStorm can now help you work with shell scripts. Code completion works in .sh and .bash files, a new run configuration is available, and the IDE integrates with ShellCheck for linting and shfmt for formatting the code.

Searching for duplicate code

Searching for duplicate code

With the new Duplicate code fragment inspection, you can now find code duplicates in your project. It checks your code on the fly and immediately highlights potential duplicates in the editor. It works for JavaScript, TypeScript, CSS, Sass, SCSS, and Less.

IDE

Code style for a folder with EditorConfig

Code style for a folder with EditorConfig

You can now maintain different code styles in different parts of your projects by adding multiple .editorconfig files. In addition to the standard EditorConfig options, which have been supported for a long time, you can now use IDE-specific properties that cover all available IDE code style options.

Open multiple projects in one window

Open multiple projects in one window

When you have a project opened in WebStorm and want to open another one, you can now attach this second project to the opened one, so that you can see both of them in the same IDE window. If you want to close the attached project, right-click its root in the Project view and select Remove from Project View.

Updated plugin configuration

Updated plugin configuration

With the updated Plugin page in the IDE preferences, it is now easier to find the plugin you need – the plugin description is now shown right next to the list of available plugins. We’ve removed the Updates tab but added a new Update button next to the plugin in the Installed section.

To disable or re-enable all the downloaded plugins, click the gear icon and choose the appropriate option.

Version Control

Completion in .gitignore

Completion in .gitignore

In .gitignore files, the IDE offers code completion suggestions for file and folder names. Cmd/Ctrl-click on the name to jump to this file or folder in the Project view. You can now quickly add a file to .gitignore from the Local Changes tab – right-click it in the Unversioned files group and select Add to .gitignore.

JavaScript & TypeScript

Using JavaScript destructuring

Using JavaScript destructuring

With destructuring, you can unpack values from arrays and objects into variables using a very concise syntax. WebStorm’s new refactorings and intentions (Alt-Enter) can help you easily introduce destructuring to your JavaScript or TypeScript code.

Convert function with Promise to async/await

Convert function with Promise to async/await

You can automatically change a function that returns a Promise with .then() and .catch() calls to an async function that uses the async/await syntax. Simply press Alt-Enter on the name of the function and select Convert to async function. This is possible not only in TypeScript files, but also in JavaScript and Flow.

Convert function with Promise to async/await

New inspections for Angular apps

For Angular applications, WebStorm adds 17 new inspections that will help you detect Angular-specific errors in your app as you type, and will suggest quick-fixes. These inspections work both in the TypeScript and template files and check the use of bindings, directives, components, and many other things.

Easier navigation in Angular projects

Easier navigation in Angular projects

In Angular apps, you can now use the Related Symbol… popup (Ctrl-Cmd-Up / Ctrl+Alt+Home) to quickly jump between the different component files such as TypeScript, template, style, and test files. In the TypeScript file, the popup will also list all the symbols that were imported into this file.

Improved support for TypeScript in Vue apps

Improved support for TypeScript in Vue apps

WebStorm now uses the TypeScript language service together with its own TypeScript support for any TypeScript code in .vue files. This means that you’ll now get more accurate type checking and type info, you will be able to use the quick-fixes provided by the service, and see all the TypeScript errors in the current file in the TypeScript tool window.

Extract Method for React hooks

The Extract Method refactoring now works with local functions and uses destructuring for the return values, making it perfect for extracting custom React hooks.

Improved completion for props

WebStorm now provides better code completion for React props merged using with the spread operator.

HTML and Style Sheets

Updated docs and browser compatibility

Updated documentation

The documentation (F1) for CSS properties and HTML tags and attributes now shows up-to-date descriptions and information about the browser support from MDN as well as links to the full MDN articles.

Browser compatibility check for CSS

To check that all the CSS properties you use are supported in the target browser version, you can enable a new Browser compatibility inspection in preferences.

Camel case support for CSS Modules

If you use CSS Modules in your project, code completion for classes in the JavaScript file will now suggest camel-cased versions of class names with dashes.

Extract CSS variable

With the new Extract CSS variable refactoring, you can replace all the usages of a value in a current .css file with a variable by using the var(--var-name) syntax.

Testing

Highlighting for failed line in test

Highlighting for failed line in test

When you run tests with Jest, Karma, Mocha, or Protractor and some tests fail, you can now see right in the editor where the problem happened. The IDE will use the information from the stack trace and highlight the failed code. On hover, you’ll see the error message from the test runner and you can immediately start debugging the test.

Testing with Cucumber and TypeScript

Using Cucumber and TypeScript? You can now jump from the steps in the .feature file to their definitions in the .ts file, and generate missing definitions using a quick-fix (Alt-Enter).

Tools

New debugger console

New debugger console

Meet the new, improved interactive debugger console in the JavaScript and Node.js debug tool windows! It now displays objects using a tree view, and it supports styling of log messages with CSS and grouping them using console.group() and console.groupEnd(). You can also filter out any type of log messages.

Completion for npm scripts

Completion for npm scripts

When adding new scripts to the package.json file, WebStorm now provides suggestions for available commands provided by the installed packages. After typing node, the IDE will suggest folder and file names. And after typing npm run, you’ll see a list of tasks defined in the current file.

Improved support for linters

WebStorm can now run multiple processes for ESLint and TSLint in one project to make sure that they work correctly in monorepo-projects and in projects with several linter configurations.

Support for Docker Compose

If you use Docker for testing your Node.js application, you can now use the configuration described in the Docker Compose file to easily run and debug the app from the IDE.

Version range tooltip for dependencies

In package.json, press Cmd/Ctrl and hover over the version on a dependency to see what range of versions can be installed when running npm install or yarn install.

IDE

New UI themes

New UI themes

You can now use the new colorful UI themes in WebStorm that are available as plugins. Choose between the Dark Purple, Gray, and Cyan Light themes, or create your own.

Recent locations popup

Recent locations popup

The Recent Locations popup (Cmd-Shift-E / Ctrl+Shift+E) is a new way to navigate around the project. It shows a list of all the files and lines of code in them that you have recently opened in the editor. You can start typing to filter the results and jump to the code you need.

Save project as a template

With the new action Save as a Template in the Tools menu, you can now use a project as a base for creating new projects on the IDE Welcome Screen.

Soft-wraps for selected file types

You can now enable soft-wraps in the editor for specific file types. To do that, open Preferences/Settings | Editor | General and specify the file types in the Soft-wrap files field.
