This package extends the parser of js2-mode
to support JSX syntax.
Defines a major mode rjsx-mode
based on js2-mode
for editing JSX files. rjsx-mode
extends the parser in js2-mode
to support the full JSX syntax. This means you get all of the js2
features plus proper syntax checking and highlighting of JSX code blocks.
Some features that this mode adds to js2:
Highlighting JSX tag names and attributes (using the rjsx-tag and rjsx-attr faces)
Highlight undeclared JSX components
Parsing the spread operator ...otherProps
Parsing && and || in child expressions cond && <BigComponent/>
Parsing ternary expressions toggle ? <ToggleOn /> : <ToggleOff />
Additionally, since rjsx-mode extends the js2 AST, utilities using the parse tree gain access to the JSX structure.
