Koa: Dive into typescript

[leaxoy]

Is there any plan write koa with typescript in the next major release v3.
As everyone knows, typescript is a strong type language.It means we can take few mistakes.
It also means we can write simple but easy understand code thanks to the type hint provide by typescript.

nope sorry, I don't see a point here, Koa is really simple as-is and any mistakes must be covered by tests anyway.

there has been a lot of discussion on typescript lately. the consensus of maintainers seems to be not do do it (as is also my personal opinion), you can read up on everything here: https://github.com/koajs/koa/issues?utf8=%E2%9C%93&q=typescript.

Closing for now.

You can just install the type files using npm i -D @types/koa and you'll have the type hints you need.

Well, "Koa is simple and mistakes must be covered by tests anyway" indeed. But Koa with a lot of middlewares is not simple anymore. It's time for nodejs to scale now and it's time for the whole nodejs community to consider further.

@tj at you because this issue was closed.

@xialvjun Throwing a new language at that problem isn't practical. If you feel like ts is helping you, then there's nothing stopping you. Koa itself is pretty lean.
