TS7016: Could not find a declaration file for module '../../../secret/firebaseConfig.js'. How can it be corrected?

Question

JavaScript

Deploy the project to typescript. I connect the Firebase config.
The project does not compile due to an error

[tsl] ERROR in D:\DESKTOP\BSM\Repos\check-out-dev\src\components\api\api.ts(4,32)
      TS7016: Could not find a declaration file for module '../../../secret/firebaseConfig.js'. 'D:\DESKTOP\BSM\Repos\check-out-dev\secret\firebaseConfig.js' implicitly has an 'any' type.

firebase config connected as

export const firebaseConfig = {
    apiKey: 'хххх',
    authDomain: 'ххххх.firebaseapp.com',
    databaseURL: 'https://ххххххv.firebaseio.com',
    projectId: 'ххххх',
    storageBucket: 'хххххххххххх',
    messagingSenderId: 'хххххххх',
    appId: 'ххххххх',
}

Answer 1

Change the config file extension to .ts
