Install

Requires mongoose v6+ to be a dependency in your project.

npm:

npm install @ladjs/mongoose mongoose

Usage

const Mongoose = require('@ladjs/mongoose');
const { Schema } = require('mongoose');

(async () => {
  const m = new Mongoose({
    mongo: {
      options: { heartbeatFrequencyMS: 100, serverSelectionTimeoutMS: 1000 }
    }
  });

  const conn1 = await m.createConnection('mongodb://server-one.example.com/database-name').asPromise();
  const conn2 = await m.createConnection('mongodb://server-two.example.com/database-name').asPromise();

  const UserSchema = new Schema({ name: String });
  const LogSchema = new Schema({ name: String });

  const Users = conn1.model('Users', UserSchema);
  const Logs = conn2.model('Logs', LogSchema);

  // write to the server-one.example.com database
  await Users.create({ name: 'test' });

  // write to the server-two.example.com database
  await Logs.create({ name: 'test' });
})();

Note that instances of this class Mongoose only have the method createConnection. It is not 1:1 with mongoose normal singleton.

You should use @ladjs/graceful to manage process SIGHUP and graceful exits.
