A new WebStorm 2017.2 EAP build (172.3095.13) makes it easier to manage project’s dependencies: the IDE will suggest you running
npm install or
npm update when you open a project, update it from the version control or edit package.json.
For the full list of issues addressed in this EAP build, see the Release notes.
You can install this WebStorm 2017.2 EAP build via Toolbox App or by downloading it on this page. It can be installed side-by-side with your stable WebStorm version. A patch update from the last week EAP build is also available.
