Look and Feel

Reworked Welcome screen and faster initial setup

We’re continuing to improve WebStorm’s look and feel. First of all, we’ve updated the Welcome screen. The main goals behind this change were to simplify the initial setup of the IDE and make it easier to manage some of the key settings. Let’s see what’s changed.

When you start WebStorm for the very first time, you will no longer see the configuration wizard – only the Privacy Policy and License dialogs will be shown. As soon as you open your projects, they will be displayed on the right, with the New Project, Open, and Get from VCS buttons shown in the top right corner.

new-welcome-screen-ws-2020-3

On the left-hand side of the Welcome screen, you’ll find the Customize and Plugins tabs. The Customize tab lets you tweak the most commonly used settings, like IDE themes and fonts. The Plugins tab provides quick access to the list of available plugins and allows you to install them.

customize-tab-ws-2020-3

Lastly, there’s the Learn WebStorm tab. From this tab, you can jump to our online help, as well as some other resources, such as WebStorm educational videos and the keymap reference card. It also provides access to an interactive training course.

IDE theme synced with OS settings

Another improvement involving the look and feel is the ability to sync your IDE theme with the OS settings. For now, this improvement is available only for macOS and Windows users, but we plan to implement it for Linux users later, too.

To try out the new functionality, go to Preferences/Settings | Appearance & Behavior | Appearance and select the Sync with OS option there. Click on the gear icon next to the Theme drop-down menu to choose the preferred light and dark themes.

Improvements for working with tabs

With WebStorm 2020.3, we’ve made working with tabs more convenient.

First, you can split the editor by dragging a tab to the desired place and dropping it there. The split actions within the tab’s context menu are still available, too.

split-tabs-with-drag-drop

We’ve also implemented a new Open in Right Split action. This action will help you open new files without losing sight of the file you’re currently working with. You can find more information about how it works in this blog post.

open-in-right-split-from-project-view

Finally, pinned tabs are now marked with a special icon and shown at the beginning of the tab bar so you can find them faster. Also, if you tend to open a lot of tabs, you can now keep all your pinned tabs in a separate row. To do this, go to Preferences/Settings | Editor | General | Editor Tabs and tick Show pinned tabs in a separate row.

pinned-tab-ws-2020-3

Make WebStorm open specific files by default

Making WebStorm the default application for specific file types is now simple. Go to Preferences/Settings | Editor | File Types and click the Associate File Types with WebStorm button. Then select the file extensions you want to open with WebStorm and click OK.

set-file-type-associations-ws-2020-3

Depending on your OS, you might need to restart the machine for changes to be applied. The selected file extension associations will remain unchanged when you upgrade to a newer version of your IDE.

Custom multi-file templates

We’ve implemented the ability to add custom file templates that create several files at once. This can be handy when, for example, you need to add a .js file along with a test file for it.

To give this new functionality a try, go to Preferences/Settings | Editor | File and Code Templates, click + to create a new template, and then click the Create Child Template File icon next to +. You’ll see a new node appear under the parent file.

In the File name field, you can specify a pattern for generating a file name and a path to it using the supported syntax.

create-js-multi-file-template

Once you’ve saved the new template, you can start using it as usual.

Other notable improvements to WebStorm’s look and feel include a new Reader mode, an alternative keymap for macOS, the Expand All button for the Project view, and a new action for transposing characters (press Shift+Shift and look for transpose to try it out).

Frameworks and Technologies

Tailwind CSS support

One of the most long-awaited improvements, support for Tailwind CSS, has finally landed in WebStorm! Let’s see how this can help you work with this popular framework more efficiently.

First, you can now expect WebStorm to autocomplete Tailwind classes in your HTML files and after the @apply directive. You’ll also see completion suggestions for pseudo-class variants.

tailwind-completion-after-apply

If you hover over a class in your HTML and CSS files, the IDE will show you a preview of the resulting CSS. You can also see this preview when autocompleting your code with the help of the Documentation popup (F1/Ctrl+Q).

tailwind-class-declaration-preview-from-doc-popup

Besides that, WebStorm now supports the customizations you make using tailwind.config.js files. The IDE analyzes those files and provides completion based on your customizations. If you define a custom theme with new colors, for example, you’ll see newly generated classes with the name of the custom color in the completion popup.

tailwind-customization-support

That’s all for now about Tailwind CSS support. Please try the existing features and share your feedback with us! We plan to improve this support further.

Create a React component from its usage

As you might know, WebStorm constantly checks that referenced variables and fields are valid. When they aren’t, the IDE can suggest creating the relevant code construct for you. Now it can do this for React components, too. Place the caret at an unresolved component, press Alt+Enter, and then select the corresponding inspection. That’s it!

create-react-component-from-usage

Enhancements for Vue.js

We didn’t have any big updates to Vue support planned for this release, but there’s still a little something to help you work with Vue better.

First, we’ve fixed a number of issues related to Vue 3. For example, WebStorm now supports the newly introduced <script setup> syntax.

script-setup-vue

Besides that, we’ve made the IDE correctly apply ESLint code style rules in Vue projects, and we’ve improved the integration with the TypeScript language service. To learn about other Vue-specific improvements, check out our release notes.

Markdown editing and preview enhancements

With WebStorm 2020.3, we’ve significantly improved the experience of working with .md files.

You can now reformat the content of your .md files to be in line with popular Markdown style guides. To do so, press ⌘⌥L / Ctrl+Alt+L. You can modify the related code style settings in Preferences/Settings | Editor | Code Style | Markdown.

reformat-md-file

Whenever you switch to a custom UI theme, WebStorm will automatically change the color of the preview pane.

markdown-preview-pane-custom-theme-ws

We’ve also added support for Mermaid.js, a popular diagramming and charting tool. You can turn it on in Preferences/Settings | Languages & Frameworks | Markdown.

Finally, if you click the Auto-Scroll Preview button in the top right corner of the preview pane, that pane will be synced to scroll along with the editor.

Full support for pnpm

WebStorm now fully supports the pnpm package manager, along with npm and yarn. Over the last year, we’ve been gradually adding improvements around pnpm support. With v2020.3, we’ve put the finishing touches on it.

If you open a project with a pnpm-lock file and have pnpm installed on your machine, WebStorm will automatically change the package manager for this project to pnpm. Also, there’s now a dedicated pnpm option in the list of package managers under Preferences/Settings | Languages and Frameworks | Node.js and NPM. Other things like the ability to run and debug scripts or the Run ‘pnpm install’ warning were already introduced in v2020.2.

pnpm-package-manager-in-preferences

That’s it for the largest improvements to frameworks and technologies. We’ve also added basic support for multiple webpack configs and made ESLint configuration more flexible.

JavaScript and TypeScript

Integrated TypeScript and Problems tool windows

We’ve integrated the TypeScript language service into the Problems tool window and removed the dedicated TypeScript tool window. We made this change to help you review all the critical problems in your code from one place. All the errors reported by the service can now be found under the Project Errors tab of the Problems tool window.

integrated-ts-problems-tool-windows

To access the buttons that were previously available in the TypeScript tool window, you can use a new TypeScript widget on the status bar. From there, you can compile your code, restart the language service, and jump to TypeScript settings.

Better formatting for template literals with CSS and HTML

With libraries like styled-components and lit-html becoming more popular, quite a lot of CSS and HTML code is now written inside JavaScript template literals. These blocks in JavaScript code can also have expression interpolations with JavaScript in them.

Starting with v2020.3, WebStorm will properly support code formatting in JavaScript for multiline CSS and HTML blocks with JavaScript inside them. The IDE will indent correctly when you add code in these more complex template literals or reformat your code.

better-formatting-for-css-html-template-literals

Improved debugging experience

You might already know that when execution is stopped on a breakpoint, WebStorm shows you hints with the values of the variables right next to their usage. To make these hints more helpful, we’ve introduced some improvements.

First, the inline hints are now interactive. You can click on them to see all the fields that belong to the variable. You can also change the variable values inside the drop-down list by clicking Set Value.

interactive-hints-popup-ws

Another update affects watches. Previously, your watches were kept under the Variables tab of the Debug tool window. When you stepped through the code and moved to a different context, the watches could turn into errors.

Though you can still add watches this way, in v2020.3 we’ve solved the issues mentioned above by adding inline watches. Now, you can tie your watch expression to the place in the code where it is relevant. For this, click on Add as Inline Watch in the same popup. Alternatively, you can use the Add Inline Watch action from the context menu.

add-inline-watch-ws

Lastly, we’ve merged the Step Into and Smart Step Into actions into one. You can find more information about this change here.

Better completion suggestions for strings

When working with strings in JavaScript and TypeScript, you’ll see a minor improvement to code completion. The IDE now suggests the content used in other strings in your project. This may be handy when working with string parameters.

improved-completion-suggestions-for-strings-js

Tools

Support for our collaborative development tool

WebStorm 2020.3 supports Code With Me (EAP), our new tool for collaborative development and pair programming. This tool lets you share projects with others so you can work on them together in real time. To try Code With Me, install the corresponding plugin from Preferences / Settings | Plugins.

code-with-me-plugin

Built-in training course on WebStorm basics

From now on, WebStorm will come bundled with the learning plugin and will include an interactive training course. This course can help you learn how to do a variety of common tasks, such as refactoring code, navigating through projects, and more. You can find it under the Learn WebStorm tab on the Welcome screen or by going to Help | IDE Features Trainer from the main menu.

training-course-ws

The course is divided into several modules, each with a number of lessons that teach you how to do a specific task. There is no need to go through all the lessons – you can choose to do only the ones you find most relevant.

Improved spelling and grammar checking

You can now address grammar and spelling issues faster – hover over problems and you’ll get a popup with an explanation and a suggested fix. To see the full list of actions available in the current context, click More actions or press Alt+Enter.

spell-checker-improvements-2020-3

We’ve also updated to a new version of the grammar checking engine with support for more languages and higher quality grammar checks.

cURL conversion in the HTTP client

You can now export an HTTP request to cURL. For this, press Alt+Enter in the HTTP request editor and select Convert to cURL and copy to clipboard.

export-http-requests-to-curl

WebStorm 2020.3 also comes with several improvements to LightEdit mode and the ability to share run configuration templates with others.

Version Control

Support for the Git staging area

Note: This functionality is only available for the Commit tool window. You can enable it by ticking Use non-modal commit interface in Preferences/Settings | Version Control | Commit.

With this update, we’ve introduced support for the Git staging area. To turn it on, tick the Enable staging area checkbox in Preferences/Settings | Version Control | Git. Once you do, the support for changelists will be disabled.

If you go back to the commit UI, you’ll see that it contains staged and unstaged files. When you’re ready to stage a file, simply click the + icon next to it. The file will appear under the Staged node.

stage-unstage-file

You can also stage changes right from the gutter or when using the Show Diff feature.

stage-file-from-show-diff

When you click Commit, all staged files will be committed.

Improved work with branches

Several enhancements in this release touch upon branches. First, the IDE now automatically corrects unaccepted symbols in the names of new branches, helping you create branches in line with the accepted format.

branch-wrong-symbols-used-ws

Second, the IDE will now show you all the actions available for the currently selected branch, just like it would for other branches.

new-actions-for-current-branch-ws

Finally, for remote branches, we’ve renamed the Merge into Current and Rebase Current onto Selected actions as Pull into Current Using Merge and Pull into Current Using Rebase, respectively.

Rearranged VCS menu

The VCS group under the main menu is now named after the version control system you are using. We made this change as terms like Git are used more commonly than VCS and should be clearer for more people. We’ve also rearranged the items under Git in the main menu to make the most common Git operations easier to access.

vcs-menu-2020-3

Quick file preview

You can now preview files in the editor whenever you select them in the Project view! To turn this feature on, click the gear icon in the Project view and select both Enable Preview Tab and Open Files with Single Click. If you start editing a file opened this way, it will stop being a preview and will become an ordinary file.

preview-files-from-project-view-ws

More helpful Navigation bar

The Navigation bar, a quick alternative to the Project tool window, is one of the handiest navigation features available in WebStorm. It lets you go through the structure of your project and open specific files. Starting with v2020.3, the Navigation bar will also let you jump to specific code elements in your JavaScript and TypeScript files.

improved-navigation-bar-ws-2020-3

More powerful Search Everywhere

With v2020.3, the Shift+Shift popup will become even more helpful. First of all, you can now do some math from it, similar to how you would do this using the system-wide search on your machine. The results will appear right in the popup.

search-everywhere-do-math

The popup will also let you look for Git data, including information about branches and commits.

search-everywhere-git

Besides that, all the findings are now grouped based on their relevance to the search query instead of their type.

Those are the most notable highlights. For the full list of new features and enhancements available in WebStorm 2020.3, see the release notes. Please share your feedback with us and report any issues you encounter to our issue tracker.
