Sending password reset email after user has been created with Firebase Admin SDK (Node.js)

1. Install Firebase's Node modules

Install the Firebase Node modules:

$ npm install firebase firebase-admin --save

1. How many TR-based programs exist in the US today?

10.5 (Goodwill's New Vision in Virginia mentions a service very similar to TR, but it omits any information on how to access it or how to sign up for that matter.)

There are also 7 active services that have non-TR-based phone access to their content to access the broadcast currently on the air.

2. How many TRP programs have gone out of existence in the past 5 years or so?

4 TR programs and 17 radio reader services went down. Included the radio reader services as well, because most of these programs started out as one and both types face the same challenges.
