WebStorm 2017.2 EAP 172.2827: Better Webpack Support, Convert to Export & Breadcrumbs for JS
This week WebStorm 2017.2 EAP build (172.2827.22) brings lots of new features that we’d like you to try. Download the EAP build on this page or by using Toolbox App. A patch update from the last week EAP build is also available.
Support for webpack enhanced module resolution
This update brings a huge improvement in working with projects using webpack. WebStorm now analyzes the webpack configuration and provides coding assistance that respects the webpack module resolution. That means that now all the import statements in the code that use enhanced module resolution will be properly resolved.
WebStorm runs webpack under the hood when you open a project or change webpack.config.js and, thanks to the information it gets, WebStorm now properly understands the project resolve roots and resolve aliases.
Now you don’t have to manually mark the directories as Resource roots in Preferences | Directories to fix the unresolved imports – they will just work fine.
In this project
react-color is an alias for the path
'./src/index.js'. Now WebStorm is able to properly resolve the import from
react-color, provide navigation to it and completion for the exported symbols.
Working with Version Control: inspections for commit message, Reword and Revert Commit actions
Many projects have commit message guidelines. WebStorm now allows you to configure the format of the commit message for the project. The IDE will show whether the message satisfies it and will suggest quick-fixes. You can do that in Preferences | VCS | Commit Dialog.
We’ve added a Revert commit action for Git. As the name suggests, it will help you revert a commit that’s already been pushed. To find it, right-click on the commit in the Log.
Also in the log you can find the new Reword action. It lets you change the commit message for any commits that are not pushed yet.
The Shelf tab has been redesigned and now offers you a Preview.
Another great way to navigate around the file structure is by using the Structure view. You can open it as a tool window or use it as a popup (press Cmd-F12 on macOS or Ctrl+F12 on Windows & Linux).
Converting module.exports into ES6 export
For the past year we’ve been adding various inspections that help you migrate your code to ES6. These include converting function to arrow function, var declarations to let and const, require calls to import statements, and strings to template strings.
The new quick-fix can convert
export default and
export, if that’s possible. To use it, press Alt-Enter on the
module.exports and select Convert to export.
Please note that the inspection doesn’t ensure that name exports are imported with the correct ES6 syntax.
You can also run the inspection called “
module.exports is used instead of
export” for a bunch of files using Inspect code… action and apply the fix for all of the files.
By default the inspection “
module.exports is used instead of
export” only provides a quick-fix and doesn’t highlight
module.exports statements in your code. If you want highlighting, you can enable it in Preferences | Editor | Inspections.
Nested files in Project view
Some time ago we started visually grouping together generated files in the Project view, e.g. generated .js and .js.map files were grouped with the .ts file in the same folder with the same name.
Now you can configure what files are visually grouped together. Click the gear icon in the Project view, select File nesting… and add your own patterns. For example, you can group together .ts, .html and .css files of an Angular component.
