## Skip typechecking

It is often better to use `tsc --noEmit` to typecheck as part of your tests or linting. In these cases, ts-node can skip typechecking.
It is often better to typecheck as part of your tests or linting. You can use `tsc --noEmit` to do this. In these cases, ts-node can skip typechecking making it much faster.

To skip typechecking in ts-node, do one of the following:

* Enable [swc](./swc.md)
* This is by far the fastest option
* Enable [`transpileOnly`](./options.md#transpileonly) to skip typechecking without swc

## With typechecking

If you absolutely must use ts-node for typechecking:

* Avoid dynamic `require()` which may trigger repeated typechecking; prefer `import`
* Try with and without `--files`; one may be faster depending on your project
* Check `tsc --showConfig`; make sure all executed files are included
