A node module without typing

A node module without typing

I am using module passport-google-oauth20 and Typescript version 2.2.1 with noImplicitAny

set to true. I tried to set typing with

yarn add @types/passport-google-oauth20

but i get the error

error Couldn't find package "@types/passport-google-oauth20" on the "npm" registry.

When I import the module using import {Strategy} from 'passport-google-oauth20';

, I get the error error TS7016: Could not find a declaration file for module 'passport-google-oauth20'. ... implicitly has an 'any' type.

I want to get rid of this error.

Alternatively, @types/passport-google-oauth20

I found typing here and installed it via typings . Then I referenced it with

/// <reference path="../../../typings/index.d.ts" />

But I am getting error error TS2451: Cannot redeclare block-scoped variable 'Strategy'.

.

Then I tried to write my own file like passport-google-oauth20.d.ts

:

/// <reference types="passport"/>

import passport = require('passport');

declare class Strategy implements passport.Strategy {
    public name: string;
    public constructor(options: IStrategyOption,
                verify: (accessToken: string,
                         refreshToken: string,
                         profile: Profile,
                         done: (error: any, user?: any, info?: any) => void) => void);
}

and enable it with /// <reference path="./passport-google-oauth20.d.ts" />

. Now I get again

error TS7016: Could not find a declaration file for module 'passport-google-oauth20'... implicitly has an 'any' type.

When i need it

const google = require('passport-google-oauth20');
...
public create(): google.Strategy {

I get it error TS2503: Cannot find namespace 'google'.

. When I change the code to

const Strategy = require('passport-google-oauth20');
...
public create(): Strategy {

I receive error TS2304: Cannot find name 'Strategy'.

.

So, all I want to do is use passport-google-oauth20

with noImplicitAny

. Can anyone tell me how? Usually I have no problem when there is no text input, I just switch to require

, so I want to know what is special about this.
