MongoDB Stitch - Backend as a Service

Explore MongoDB Stitch, a powerful Backend as a Service (BaaS) platform that simplifies building web and mobile applications by providing a serverless backend and integration with MongoDB databases.

Prerequisites

Before you begin, make sure you have the following prerequisites:

• A MongoDB Atlas account (Stitch is integrated with MongoDB Atlas).
• Basic knowledge of web development, MongoDB, and JavaScript.

1. Introduction to MongoDB Stitch

Understand what MongoDB Stitch is, its features, and how it simplifies the development of web and mobile applications by providing a serverless backend.

2. Creating a Stitch Application

Learn how to create a Stitch application in the MongoDB Atlas dashboard. Sample code for initializing a Stitch client in a web app:

// Initialize the Stitch client
const client = Stitch.initializeDefaultAppClient('your-app-id');
        

3. Authentication and User Management

Implement user authentication and management using Stitch's built-in authentication providers or custom authentication. Sample code for user authentication:

// Authenticate a user
const emailPasswordCredential = new EmailPasswordCredential('user@example.com', 'password');
client.auth.loginWithCredential(emailPasswordCredential)
    .then(user => {
        // User is authenticated
    })
    .catch(err => {
        // Authentication failed
    });
        

4. Data Access with Stitch Functions

Use Stitch Functions to create serverless functions that access and manipulate data in MongoDB. Sample code for creating a Stitch Function:

// Create a Stitch Function
exports = function(arg1, arg2) {
    // Function logic, e.g., reading or writing data to MongoDB
};
        

5. Integration with Web and Mobile Apps

Integrate your web and mobile applications with Stitch by making API requests to Stitch functions. Sample code for calling a Stitch Function from a web app:

// Call a Stitch Function
const result = client.callFunction('functionName', [arg1, arg2]);
        

6. Real-Time Data with Change Streams

Implement real-time data updates using MongoDB Change Streams and Stitch Triggers. Sample code for setting up a Change Stream trigger:

// Set up a Change Stream trigger
const db = client.getServiceClient(RemoteMongoClient.factory, 'mongodb-atlas').db('your-database');
const collection = db.collection('your-collection');
const changeStream = collection.watch();
changeStream.on('change', (event) => {
    // Handle real-time data changes
});
        

7. Deploying and Scaling

Learn how to deploy your MongoDB Stitch application and scale it to accommodate increasing user loads.
