TypeScript's command-line compiler tsc without type-checking. Benefits:

• Still checks and reports syntax errors.
• Exit code indicates syntax errors only; is not affected by type errors.
• Faster, since it skips typechecking and doesn't need to parse .d.ts files or perform import resolution.

Lots of TypeScript tools have an option to skip typechecking. (ts-node, ts-loader, ts-jest, etc) I'm not aware of one that performs command-line compilation like tsc.

Note: you must manually install typescript as a dependency. This package does not declare it as a dependency.

Usage

Run in the root of your project.

$ tsc-to

If you prefer a more explicit name:

$ tsc-transpile-only

Limitations & Behavior

At the moment, this tool does not accept any CLI options.

• CWD is used to discover tsconfig.json.
• Will only compile files referenced in tsconfig.json "includes", "files", and "excludes". Module resolution is skipped, so transitive dependencies are not compiled.
• Reports "options" and "syntactic" diagnostics in --pretty mode only. In the future I would like to add non-pretty and JSON outputs.
• Does not generate .d.ts files. Typechecking is required for that; use tsc.
• Logging is diagnostic and subject to change. I would like to make it more closely match tsc's behavior in the future.
