In the CSS section CSS variables can now be extracted. Again, a new refactoring was introduced. Also new is the support for features from Less 3.0. For the HTML support was worked on the documentation, as well as on the integration of Pug.
Angular, Vue and React: What has happened?
Angular has received a total of 17 new inspections in WebStorm 2019.1, including one that suggests adding a component to a module if it would otherwise be outside the scope of the module. Also for Angular, a new navigation within the IDE is available, which should facilitate the change between different project components. React has received support for Custom React Hooks, which can now be created using the Extract Method. For Vue.js, the WebStorm team has been working on TypeScript support.
Several changes in WebStorm 2019.1 also affect Node.js and npm. For example, in Node applications it is now possible to launch and debug applications from the IDE using the Docker Compose file. In addition to WebStorm 2019.1 has also done a lot in terms of linting, testing, debugging and the interface of the IDE itself.
