Installing mongoose is as easy as running the
npm install mongoose --save
But make sure you have also installed
MongoDB for your OS or Have access to a MongoDB database.
1. Import mongoose into the app:
import mongoose from 'mongoose';
2. Specify a Promise library:
mongoose.Promise = global.Promise;
3. Connect to MongoDB:
mongoose.connect('mongodb://127.0.0.1:27017/database'); /* Mongoose connection format looks something like this */ mongoose.connect('mongodb://USERNAME:PASSWORD@HOST::PORT/DATABASE_NAME');
By default mongoose connects to MongoDB at port
27017, Which is the default port used by MongoDB.
To connect to MongoDB hosted somewhere else, use the second syntax. Enter MongoDB username, password, host, port and database name.
MongoDB port is 27017 by default; use your app name as the db name.
