Autocomplete html tags in jsx (sublime text)

Worth noting that you can enable Sublime's built-in tag closer in JSX by copying and slightly modifying the keybinding for / that comes with Default.sublime-package. Add the following to your custom keymap:

{ "keys": ["/"], "command": "close_tag", "args": { "insert_slash": true }, "context":  [    { "key": "selector", "operator": "equal", "operand": "(text.html, text.xml, meta.jsx.js) - string - comment", "match_all": true },    { "key": "preceding_text", "operator": "regex_match", "operand": ".*<$", "match_all": true },    { "key": "setting.auto_close_tags" }  ]}

Assuming you're using the Babel package, the selector meta.jsx.js will match JSX syntax and enable the tag-closing behavior. The scope name may be different for other packages, in which case you can use ScopeHunter to inspect the scopes that are applied by your preferred JSX syntax.

Install:babel & Emmet

Then add this into your Key Bindings - User

"Key Bindings - User" is on "Preferences > Key Bindings"

{    "keys": ["tab"], "command": "expand_abbreviation_by_tab", "context": [        {            "operand": "source.js",             "operator": "equal",             "match_all": true,             "key": "selector"        },        {               "key": "selection_empty",             "operator": "equal",             "operand": true,            "match_all": true         }    ]},{ "keys": ["tab"], "command": "next_field", "context":    [        { "key": "has_next_field", "operator": "equal", "operand": true }    ]}

It will not autoclose the brackets for you as you type, but you can just use Sublime's built-in tag closer with commandoption. for mac, or alt. for windows.
