Support for TypeScript definition files

[mbektimirov]

After the first look on Flow I can say it is inlined Typescript. Are you planning to support .d.ts definitions to make type headers unified? And what about es6 state? Does flow support it?

[benjamingr]

Supporting importing of .d.ts could be awesome, even if it'd only work 95% of the time. Especially if the type system is easier to migrate to than with TS (kind of like PHP and hack)

What do you mean by ES6 state?

Regarding ES6, there's something on their blog post: https://code.facebook.com/posts/1505962329687926/flow-a-new-static-type-checker-for-javascript/#compatibility

It already supports various ES6 features such as destructuring, classes, extended objects, optional function parameters, and core API extensions (e.g., Map, Set, Promise, and new methods on Object, Array, and Math). Other features (notably modules) are on the way. Flow supports modules organized following the CommonJS / Node.js specification.

This is on our short-term todo list. See http://flowtype.org/docs/coming-soon.html#_

I'm going to split off the ES6 part of the original question into another issue & merge other TypeScript-related issues with this one.

+1 This would make flow a lot more viable as a type checking system for our production code.

Is there any progress/roadmap on this issue?

Is "flow convert" command currently considered usable ? I'm not sure if there is currently an official way to convert .d.ts files but i know there has been some work into supporting this kind of conversion.

[gitawego]

that would be much better for third party definitions, with a simple tsd install react --save, I could easily use either flowtype or typescript

Wanted to bump this again since it's been over a month with no response. Is this in progress at all? Are there reasons for it not being in progress? Is this a good candidate for someone in the community to build?
