tsc that skips typechecking but still fails on syntax errors.
Sometimes you want to use TypeScript, but you're migrating a legacy project. So you have type errors. Maybe not everyone on your team
is an expert at type annotations yet. Or maybe you renamed some old
.js files to
.ts so you can add annotations slowly over time, and you don't want to spam
any all over the place.
You want to
tsc your code, and you want it to fail on syntax errors. (
const foo = = this is wrong;)
But you don't want it to fail on semantic errors.
This is a quick, 1 hour hack to write a
tsc alternative that compiles your code just like
tsc but skips typechecking.
Install this module alongside the version of "typescript" you want to use.
npm install typescript-transpile-only npm install typescript
tsc-transpile-only instead of
tsc. For example:
tsc-transpile-only --project .
No tests; use it at your own risk. Or look at the code; it's tiny.
Does not support
The only one that makes sense in this context is
--build, but you can easily workaround this by invoking
tsc-transpile-only multiple times.
Exit codes are valid but don't exactly match
tsc uses different non-zero error codes depending on the reason for failure. We use exit code 1 for all failures; 0 for success. (no syntax errors)
