npm install @mother/socket.io-adapter-mongo --save
How to use
const io = require('socket.io')(3000);
const mongoAdapter = require('@mother/socket.io-adapter-mongo');
io.adapter(mongoAdapter('mongodb://localhost/test'));
or pass an object:
const io = require('socket.io')(3000);
const mongoAdapter = require('@mother/socket.io-adapter-mongo');
io.adapter(mongoAdapter({
uri: 'mongodb://localhost/test',
key: 'socket.io',
mOptions: {
tls: true
}
}));
By running socket.io with the socket.io-adapter-mongo
adapter you can run
multiple socket.io instances in different processes or servers that can
all broadcast and emit events to and from each other.
If you need to emit events to socket.io instances from a non-socket.io process, you should use socket.io-emitter.
API
adapter(uri[, opts])
uri
is a a mongodb:// uri string
If using this method of calling the adapter, the uri string will used instead of the uri property in the options object.
For a list of options see below.
