Path to the angularjs-lsp server executable. If empty (default), the extension automatically downloads and manages the server binary.

`angularjsLsp.trace.server`

Traces the communication between VS Code and the AngularJS language server.

Project Configuration

Create an ajsconfig.json file in your project root to customize behavior:

{
  "include": ["src/**/*.js", "app/**/*.js"],
  "exclude": ["**/test/**", "**/vendor/**"],
  "interpolate": {
    "startSymbol": "{{",
    "endSymbol": "}}"
  },
  "cache": true,
  "diagnostics": {
    "enabled": true,
    "severity": "warning"
  }
}
