eslint-formatter-lsif

1.0.3 verified Sat Apr 25 auth: no javascript

ESLint formatter that exports lint diagnostics in LSIF (Language Server Index Format) format. v1.0.3 (latest). Stable, low activity since 2020. Uses vscode-languageserver-protocol and vscode-languageserver-textdocument. Outputs JSON-based diagnostic data for use with Sourcegraph and other LSIF-compatible code intelligence tools. Differentiates from ESLint's built-in formatters by producing machine-readable LSIF output for cross-repository code navigation.
