Atom.io: Emmet And Jsx
Answer : Open Atom -> Preferences -> Packages -> Emmet Scroll down a bit and you'll see a note about this particular issue. From there you just need to grab the correct context, which in my case was source js jsx and add it to your Keymap configuration. # Auto expanding for emmet @ 'atom-text-editor[data-grammar="source js jsx"]': 'tab': 'emmet:expand-abbreviation-with-tab' OR (with a more relaxed selector) # Auto expanding for emmet @ 'atom-text-editor[data-grammar*="js"].not:[mini]': 'tab': 'emmet:expand-abbreviation-with-tab' As of the latest version you can hit cmd + shift + e. I assume for windows or linux it would be ctrl + shift + e (Although I have not verified windows and linux one)
