Missing declaration file `redis` throw error when compiling with TypeScript with strict type checking

Could not find a declaration file for module 'redis'.
'/Users/totominc/Desktop/Git/battlr/node_modules/redis/index.js' implicitly has an 'any' type.
Try `npm install @types/redis` if it exists or add a new declaration (.d.ts) file containing `declare module 'redis';`

The only things I have done so far:

import * as Colyseus from 'colyseus';

export const server = new Colyseus.Server();

It can also be due to my tsconfig.json which have the strict property. This can be fixed by adding a vendor declaration file in Colyseus for redis (declare module 'redis';).

It’s a bit annoying to manually add this dependency to fix an error which is from the framework.

I think adding a dummy file would defeat the purpose of using types. Since redis is optional it should be up to the end user to install the corresponding types package.

That said, I think the solution is to add a note to the install section of the docs.

I’ve added @types/redis as a dependency on Colyseus. It’s ~100kb in the server just for typings but at least we don’t have unexpected errors on the consumer side anymore
