This is a language server for JavaScript and TypeScript that adheres to the Language Server Protocol (LSP). It uses TypeScript's LanguageService to perform source code analysis.

1. npm install
2. node_modules/.bin/tsc
3. node build/language-server.js

To try it in Visual Studio Code, install the vscode-client extension and then open up a .ts file.

Run node_modules/.bin/tsc --watch.

• -p, --port specifies port to use, default one is 2089
• -s, --strict enables strict mode where server expects all files to be receives in didOpen notification requests.

• You need to disable VSCode's built-in TypeScript support to avoid weird conflicts on TypeScript files (double hover tooltips, etc.). There's a hacky way to do this: add the setting {"typescript.tsdk": "/dev/null"} to your VSCode user or workspace settings.
