Mute/ignore TS2307 error from TypeScript tsc

As of TypeScript 2.6 (released on Oct 31, 2017), now there is a way to ignore all errors from a specific line using // @ts-ignore comments before the target line.

The mentioned documentation is succinct enough, but to recap:

// @ts-ignore
const s : string = false

disables error reporting for this line.

However, this should only be used as a last resort when fixing the error or using hacks like (x as any) is much more trouble than losing all type checking for a line.

As for specifying certain errors, the current (mid-2018) state is discussed here, in Design Meeting Notes (2/16/2018) and further comments, which is basically

"no conclusion yet"

and strong opposition to introducing this fine tuning.

You might find tsc-silent useful. Although, ignoring errors you have to be careful and keep in mind that errors code change, and sometimes there are many different problems reported under umbrella error.

UPDATE

This is possible in newer version of TypeScript. See answer from stsloth.

ORIGINAL ANSWER

No, there is not a way to direct the compiler to suppress TS2307. There has been some discussion about it for exactly the reason you describe. For large projects, this becomes a huge barrier to entry.

What you might be able to do is add a step to your build process that filters the error messages. That, of course, depends on how you are doing your builds.
