mongoose.connect('mongodb://localhost/test'); var ResultSchema = new Schema({ account: { type: Number, required: true, index: true, unique: true }, profitLostRatio: Number, }); var Result = mongoose.model('Result', ResultSchema); ...
The second is another way to connect your database with the command line interface. You have to download the Mongoose CLI. After downloading is completed, you have to open the Mongoose with the command line interface. Now you have to write the Mongoose, paste the MongoDB atlas copied path,...
To use Mongoose, you’ll need to install it as a dependency: npm install mongoose Here’s a basic example of how to connect to a MongoDB database using Mongoose: const mongoose = require('mongoose'); // Connect to MongoDB mongoose.connect('mongodb://localhost/mydatabase', { useNew...
