To use @types/react, do I have to prefix all my React imports with // @deno-types ?

Re: https://docs.deno.com/runtime/fundamentals/node/#importing-types

React does not ship with types, and they have to be installed at npm:@types/react.

The documentation says types have to be imported like so:

// @deno-types="npm:@types/express@^4.17"
import express from "npm:express@^4.17";

// @deno-types="npm:@types/express@^4.17"
import express from "npm:express@^4.17";

Surely I don't have to actually prefix all React imports with @deno-types? It's a lot of imports across many files.

Is there a

deno.json

deno.json

solution?

What if I were to upgrade react, do I have to do a search and replace across the codebase to update the types too?

Any help is appreciated.

It looks like Typescript has to automatically resolve packages. Maybe Deno could use the same feature? https://www.typescriptlang.org/tsconfig/#types

Looks like there is an option you can add into deno.json... https://docs.deno.com/runtime/reference/jsx/#jsximportsourcetypes

i belive if you add to the compilerOptions.types array it should type react imports

i belive currently we need to specify the deno-types comment https://github.com/denoland/deno/issues/27062
