I have started new project with Facebook's React library. And I have found that PhpStorm can't complete html-code in *.jsx files. It only do if a press "Ctrl+Space".
Here is an example.
I typed <div cla></div>
and expected drop-down list with code suggestions.
In *.html or, for example, *.ejs files there IS code completion:
Also PhpStorm cannot auto-suggest HTML-elements, cannot auto-close tags etc.
Preferences / Languages & Frameworks / JavaScript => JavaScript language version
is set to JSX Harmony
I am using PhpStorm 9.0.2 right now. Also tried in 8.0.3. Didn't work.
P.S. I watched video about React in WebStorm (A Deep Dive into WebStorm 9's New Features) and there IS auto code completion.
Completion works for me in PHPStorm 9.0.2. But, unlike completion in HTML files, it doesn't auto-popup on typing - you need to explicitly hit Ctrl+Space inside HTML tag to get the intellisense. If this doesn't work for you, please create a support ticket
