web-tree-sitter provides WebAssembly bindings to the Tree-sitter parsing library.
|

It can build a concrete syntax tree for a source file and efficiently update
|
|
the syntax tree as the source file is edited. This package provides the WebAssembly bindings
|
|
and a JavaScript API for using them in web browsers
