From YARN:

From Git:

1. Clone the plugin into your Strapi project

cd /<path-to-your-strapi-project>/src

# create plugins folder if not exists
# mkdir plugins

# go to plugins folder
cd plugins

# clone the plugin code into a folder and skip the prefix
git clone https://github.com/itisnajim/strapi-plugin-fcm.git strapi-plugin-fcm
# install dependencies
cd strapi-plugin-fcm && yarn install # or npm install

2. Enable the plugin in <root>/config/plugins.js .

module.exports = {
  // ...
  'strapi-plugin-fcm': {
    enabled: true,
    resolve: './src/plugins/strapi-plugin-fcm' // path to plugin folder
  },
  // ...
}

3. Build the plugin

# back to project root and build the plugin
yarn build # or npm run build
# start
yarn develop # or npm run develop

Configuration

• In the Firebase console, open Settings > Service Accounts.
• Click Generate New Private Key, then confirm by clicking Generate Key.
• Past the content of your downloaded service account json file into FCM Plugin Configuration > serviceAccount. (like in the picture below, then you may need to restart the server)

• In the same interface 'FCM Plugin Configuration', optionally you can provide where the devices tokens are stored, in the picture example above, I store them in User -> deviceToken (strapi generate the users database table with the name up_users).

• Optionally you can provide all the topics you have, in the 'FCM Topic' collection type (via the dashboard or via the api - Post requests).

Usage

Via the dashboard

• Enter the notification content.
• Select targets to send to.
• Click send!

Another way via the dashboard.

• you can create a new entry in the 'FCM Notification' collection type and click publish to send to the FCM.

Via the api

• First you have to enable and give routes permissions to a specific role or roles.

{
    "data": {
        "title": "OKey",
        "body": "Test body",
        "image": "",
        "payload": "",
        "targetType": "topics",
        //or "targetType": "tokens",
        "target": "client_android",
        //or multiple topics "target": "client_android,client_ios",
        //or "target": "eyJhbGciOiJFUzI1...",
        //publishedAt: null //<<- uncomment this if you want to just add an entry as a draft to 'FCM Notification' collection without publishing and sending FCM.
    }
}

• You can send an array too:

{
    "data": [{...entry1}, {...entry2}, {...entry3}, ...]
}

Trick

If you have saved the entries in the FCM Notification collection as drafts, you can scheduled them to be sent to FCM at a later time.

• Scheduled publication
• strapi-plugin-publisher
