I have enabled Flow on a JavaScript project I am developing. Since I am putting in the effort to providing type annotations, I would really like to generate *.d.ts files so the broader TypeScript community can also have type information.
How can I generate *.d.ts type definition files from Flow-annotated JavaScript?
d. ts type are automatically created at build time.
d. ts files and put them in the dist/lib folder. You do need a tsconfig. json file in the root of your project, but that should be there for the project to work anyway.
The "d. ts" file is used to provide typescript type information about an API that's written in JavaScript. The idea is that you're using something like jQuery or underscore, an existing javascript library. You want to consume those from your typescript code.
I searched for the available tools. I found the following.
The first one is the most up to date one. It can convert the whole Flow code to TypeScript. I have used it personally, and it works like a charm.
