Demo

Example with Rust Analyzer:

demo-rust-analyzer

The styling definitely needs work, but the above shows:

  • Realtime diagnostics
  • Completion with items from the server
  • Fuzzy matching (e.g., prl to println!)
  • Completion items with Markdown docs
  • Completion items with icons for each kind
  • Hover information with Markdown docs

Simple snippets are supported as well:

demo-snippet-completion

See examples/rust-analyzer to run this locally.

See examples/rust-analyzer-sync to run this locally with an ability to save the changes to disk.

See examples/web-worker for an example with simple JSON Language Server running in Web Worker. A live demo is also available at https://qualified.github.io/lsps/.

See examples/html-css-ts for a simple demo project with TypeScript + CSS + HTML editors.
