This is an implementation of a mediator using CredoJS and it is based on the Animo Mediator which implements push notifications which are sent to mobile wallets when they have a message pending.
The project uses dotenv. You can create a .env file and add environmental variables there. The app will take the values from there.
Install dependencies with yarn install
The mediator can use a PostgreSQL database with Askar. If you need to do it just set the environmental variables:
POSTGRES_HOST="" # OPTIONAL:
POSTGRES_USER="" # OPTIONAL:
POSTGRES_PASSWORD="" # OPTIONAL:
Although CredoJS works with FCM and APNs systems, this mediator only implements Firebase, which can work both on iOS and Android.
- Follow the setup for your project in Cloud messaging documenation.
- Once you are ready, get the Service Account Key. It should be a JSON file.
- Transform the file to base64.
- Add the resulting base64 to the environment variables at
FIREBASE_SERVICE_ACCOUNT="ewogICJ...." # this is your service account in base64
If you want to test before deploying:
- set your ngrok api key as
NGROK_AUTHTOKEN. - Start the mediator with
yarn run dev. - Copy the invitation url that will output at the last line in your App.
