redux-saga-test-plan: Typescript error with ^4.0.0-beta.2

I wanted to install redux-saga-test-plan and I got some typing errors. So I tried to update the dependencies and I finally end up with the following dependency versions: “typescript”: “^3.1.1”, “redux-saga”: “^1.0.1”, “redux-saga-test-plan”: “^4.0.0-beta.2”,

and I see this type-checking error:

node_modules/redux-saga-test-plan/effects.d.ts:13:16 - error TS2314: Generic type 'Pattern' requires 1 type argument(s).

13     (pattern?: E.Pattern): R;
                  ~~~~~~~~~

I also tried with the last typescript version (3.3) and same error.

I investigated a little bit and it looks like this Pattern type changed 2 months ago in redux-saga (https://github.com/redux-saga/redux-saga/blob/master/packages/types/index.d.ts) but maybe the problem appears only with the recent versions of typescript…

Hey, folks. Sorry for the delay. I’ve published v4.0.0-beta.3. I’m working with @jp928 to give him publish access so I don’t slow things down.

@Favna @fabienchn I had informed the author via another channel who has the privilege to publish to npm. It should be coming soon. Thanks for using the library.

@Fabienchn just set the “skipLibCheck” compiler option

Confirming this issue still occurs. Relevant package versions:

"redux-saga-test-plan": "^4.0.0-beta.2",
"typescript": "^3.3.3333"

Exact Error:

TypeScript error: Generic type 'Pattern' requires 1 type argument(s).  TS2314

    12 | interface TakeEffectApi<R> {
  > 13 |     (pattern?: E.Pattern): R;
       |                ^
    14 |     <T>(channel: Channel<T>): R;
    15 | }
    16 | interface PutEffectApi<R> {

It is temporarily resolved by adding "skibLibCheck": true to the tsconfig but this value should not be required for end-users
