loopback2-component-pubsub

Loopback v2.x component that injects pubsub client into the global app object.

The main difference with Loopback /change-stream channels is that this implementation creates only two observers (after save and after delete) per model and then streams the changes to keep-alive registered connections. In contrast Loopback creates two same observers for each connection.

Install and Setup

Install the company:
npm install --save loopback2-component-pubsub

Add the following configuration to component-config.json:

``javascript
{
...
"loopback2-component-pubsub": {
"projectId": "my-project",
...
},
...
}
`

Usage

Access pubsub client using app.pubsub` field.
