Plugin Ecosystem

ttsc plugins are npm packages that hook into the compiler. Once installed, every ttsc build, ttsx run, and @ttsc/unplugin bundler pass sees them. Diagnostics flow through the same stream as type errors; the VS Code extension also surfaces diagnostics/actions from plugins that opt into the LSP protocol.

First-party utility plugins

Small plugins shipped from this repo:

• @ttsc/banner: adds a fixed @packageDocumentation JSDoc banner to every emitted file.
• @ttsc/paths: rewrites compilerOptions.paths aliases into relative imports in the emit.
• @ttsc/strip: removes console.log, debugger, and other configured patterns from the emit.

For lint and format, see the dedicated Lint & Prettier chapter.

Third-party plugins

External transforms that ship through the same plugin protocol:

• typia: runtime validators, JSON tools, LLM function calling, Protocol Buffer codecs, all generated from your TypeScript types.
• nestia: NestJS controllers, OpenAPI documents, SDK generation, and E2E test scaffolding, backed by typia.

Each ships on its own release schedule with its own docs. The pages above cover “how does it slot into ttsc?”; for the full API surface follow the upstream docs (typia.io, nestia.io).

PRs adding plugins to this list are welcome. The bar is “installs and works on a current ttsc release.”
