Last release: 1 month ago

get-tsconfig is a lightweight TypeScript utility that finds and parses tsconfig.json files, including handling comments, dangling commas, and resolving the extends chain. It can also validate whether a found tsconfig applies to a specific file and provides typed, resolved tsconfig output plus helpers for matching include/exclude/files and compilerOptions.paths.

Recent updates

  • v5.0.0-beta.5

    1 month ago

    v5.0.0-beta.5 introduces TypeScript-version-aware compiler option defaults that are applied by default when calling `readTsconfig` and `getTsconfig`. The implementation auto-detects the installed TypeScript major version and then injects unconditional compiler-option defaults that TypeScript itself would synthesize at runtime.

  • v5.0.0-beta.4

    1 month ago

    This release focuses on tsconfig parsing and extends-chain handling, including fixes around how `files` and `include` interact and improved rewriting of inherited path fields. The documented surface area includes an `includes` option for `getTsconfig` and `findTsconfig`, plus a new `findTsconfig` export and a `PathsMatcher` type export.

    Features

  • v4.14.0

    1 month ago

    v4.14.0 adds a new `findTsconfig` API and introduces an `includes` option to both `getTsconfig` and `findTsconfig`. When `includes` is enabled, the implementation validates that the discovered tsconfig actually applies to the provided search path (via `files`, `include`, and `exclude`).
