|
||||||
|
This app demos an editor with language smarts (for JavaScript) by hosting the <a
|
||||||
|
href="https://microsoft.github.io/monaco-editor/">Monaco</a> editor widget with a simple <a
|
||||||
|
href="https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/">LSP</a>
|
||||||
|
server implemented via <a href="https://github.com/ebkalderon/tower-lsp">tower-lsp</a> and <a
|
||||||
|
href="https://github.com/tree-sitter/tree-sitter">tree-sitter</a>. Everything is compiled to WASM and run
|
||||||
|
client-side directly in the browser; there are no separate sever-side processes or web workers used by the app
|
||||||
|
code. (Monaco itself does use web workers, however).

features: ⇧⌘O (macos) or ⇧⌃O (windows) opens the symbol view; the <strong>syntax</strong> area shows the JavaScript syntax tree (green for valid; red for errors) parsed from the text <strong>editor</strong> area
