In Typescript, is there a way to make function parameters typing mandatory

I'm working on a big project with JS and TS files and sometimes there are no types on Typescript functions.

Since we want to use typescript to type things I would like to have a way to make function parameters mandatory with typescript CLI or ESLint, is this possible ?

Did not find anything on it.

Solution

  • TSConfig option noImplicitAny will ensure that parameters are specified and not assumed to be any.

    noImplicitReturns will also help for return types.
