Best practices to optimize the MEAN stack development for better performance

If you are familiar with tech stacks, you will know MEAN stack development involves working with four powerful technologies – MongoDB, Express, Angular, and Node.Js. Together, they make modern web applications. Are you looking for efficient performance and scalability in your MEAN stack application? Then, here are some best practices and performance optimization tips.

1. Use Mongoose for MongoDB

Mongoose is an Object-Relational Mapping (ORM) library that provides a higher-level abstraction layer. It allows developers to work with MongoDB in Node.Js. Plus, they can define data models, perform validation, and create complex queries. If you want proper data modeling, efficient database operations, and schema validation, use Mongoose. The following are steps to use Mongoose for MongoDB.

* Install Mongoose

The first step is to install Mongoose as a dependency in your Node.js application using npm or yarn.

* Import Mongoose 

Require Mongoose in your Node.Js application and connect to your MongoDB database.

* Define a Data Model

It is time when your MEAN stack development agency will define a data model with Mongoose schema. It illustrates the structure of your data, including field names, types, validation rules, and more.

* Create, Read, Update, and Delete (CRUD) Operations

In this step, you should use the model defined previously. It helps you perform CRUD operations on your MongoDB database.

* Perform Data Validation

Mongoose comes with built-in validation capabilities. They allow you to validate the data before saving it to the database.

2. Optimize MongoDB queries

As commonly known, MongoDB is a NoSQL database that stores data in JSON-like documents. To optimize query performance, index your queries properly and use the appropriate query operators for efficient data retrieval. Avoid using inefficient queries such as $or and $nor. Instead, you may leverage MongoDB’s aggregation framework for complex queries. If you are wondering how to optimize MongoDB queries, read below.

* Use Indexes

Indexes are essential in optimizing query performance in MongoDB. They help MongoDB to quickly locate and retrieve data without scanning the entire collection. Remember, your queries should use appropriate indexes on fields that developers frequently use in queries or for sorting or filtering data. There are two ways to create indexes in MongoDB using the createIndex() method or by defining indexes in your Mongoose schema with the index property.

* Use Query Operators

MongoDB has various query operators that companies offering the best MEAN stack development in the US use to perform efficient data retrieval. Go for $eq instead of $in when querying for a single value, as $eq can use indexes more effectively. Similarly, employ $lt, $lte, $gt, and $gte for range queries, and avoid using $ne and $ in as they can be less efficient.

* Avoid $or and $nor

Queries with $or and $nor may not be efficient, as they require scanning multiple index ranges. If possible, restructure your queries to use $and/or other operators for more efficient index usage.

* Utilize Aggregation Framework

MongoDB’s aggregation framework makes it easier to perform complex data manipulations and transformations directly in the database. It can help you optimize performance by reducing the amount of data transferred between the database and the application server.

* Monitor and optimize

Lastly, it is crucial to regularly monitor and analyze the performance of your queries using MongoDB’s built-in tools like explain() and MongoDB Compass. You need to identify and optimize slow queries by adding appropriate indexes. After this, you may use the aggregation framework to restructure queries. 

3. Use Middleware in Express

 The Express framework is widely recognized and utilized in the Node.Js ecosystem for developing web applications. Your MEAN stack development agency will rely on middleware to handle regularly performed tasks like request validation, authentication, and authorization. Middleware helps improve performance by reducing redundant code and ensuring consistent handling of requests.

While it is a powerful feature that allows you to handle common tasks, using it accurately is crucial. It requires code work, so hire the best MEAN stack development in the US.

4. Leverage Caching

Caching can significantly improve the performance of your MEAN stack application. It is a technique that developers use to store frequently accessed data in memory. As a result, it reduces the need for expensive database queries and improves application performance. For instance, developers can implement server-side caching using tools like Redis or Memcached to store frequently accessed data in memory. Let us learn how to implement server-side caching using Redis in a MEAN stack application.

* Install Redis

Firstly, you should install Redis on your server. To do so, follow the installation instructions provided by Redis.

* Install the Redis package in Node.Js

Next, you need the Redis package in Node.Js to interact with Redis. So, get ready to install it using npm or yarn by running the following command in your MEAN stack application’s root directory: npm install redis

* Redis in your Express application

You also need the Redis package in your Express application to create a Redis client.

* Use Redis for caching

You can now use the Redis client to implement caching in your application. For example, you have an API route that retrieves data from MongoDB and returns it as a JSON response. You can add caching to this route using Redis.

Note: Handle errors appropriately when implementing caching in your MEAN stack application using Redis or other caching tools. Do not forget to manage Redis errors, MongoDB errors, and other potential errors to ensure the smooth functioning of your application.

5. Optimize Angular templates 

Angular, a widely-used front-end framework, is one of the components of the MEAN stack. It allows developers to design dynamic web applications with robust functionality and seamless user experiences. Another practice to boost the performance of your application is optimizing your Angular templates.

* Limit using two-way data binding

Two-way data binding in Angular can be convenient. But it can also impact performance when used excessively. Each time a two-way binding is updated, Angular has to check for changes and update the DOM accordingly. Therefore, it is best to use one-way data over two-way data binding. Plus, manually handle data updates in your component’s code.

* Avoid unnecessary DOM manipulations

DOM manipulations can be expensive when it comes to performance. So, try to minimize unwanted DOM manipulations in your Angular templates to improve rendering performance. For instance, using complex expressions or functions in template bindings is a big no-no. After all, they can cause excessive re-rendering. Instead, move such logic to your component’s code and update the template only when necessary.

* Use trackBy with ngFor

Developers use Angular’s ngFor directive for rendering data lists. When employing ngFor, it is crucial to use a trackBy function because it optimizes rendering performance. The trackBy function allows Angular to efficiently track changes in the list and update only the affected DOM elements. That means it prevents re-rendering the entire list, which improves performance.

6. Implement Production-ready configurations

You might also see your MEAN stack development agency implementing production-ready configurations, including optimized database settings, secure authentication mechanisms, and appropriate security configurations for Express and Node.Js. They are crucial for ensuring the security and performance of your MEAN stack applications. The following are some recommendations for production-ready configurations for your project.

* Optimize database settings

Configure your database settings, such as connection pool size, query caching, and indexing, to optimize performance in a production environment. However, it is advisable to employ appropriate indexing strategies for frequently queried fields to speed up database queries.

* Secure authentication mechanisms

Experienced agencies will always use safe authentication mechanisms to authenticate users and protect sensitive data. Some examples include OAuth and JWT. In addition, they execute proper password hashing and encryption techniques to store user passwords securely. Enable HTTPS to encrypt data transmitted over the network and prevent eavesdropping or man-in-the-middle attacks.

* Configure suitable security settings for Express and Node.Js

Set up the security configurations for your Express and Node.Js servers, such as enabling secure headers like Content Security Policy (CSP), Strict-Transport-Security (HSTS), and XSS protection. For example, rate limiting can help you prevent brute force attacks or DDoS attacks. Besides this, you need to regularly update dependencies and apply security patches to address known vulnerabilities.

* Disable unnecessary features and plugins in production

In a production environment, disable features and plugins that are not necessary for your application’s functionality. It reduces the attack surface and minimizes the risk of security vulnerabilities. Only enable features and plugins essential for your application’s production use.

* Monitor and analyze performance

The last step is to implement monitoring and logging mechanisms to track the performance of your MEAN stack application in production. Moreover, to identify and resolve performance bottlenecks, you need to analyze performance metrics, such as response time, CPU and memory usage, and database performance. You can also employ performance profiling tools to optimize code and improve application performance.

7. Execute Scalability Strategies

Execute Scalability Strategies: Consider scalability when designing your MEAN stack applications. And your developer may use techniques like load balancing, horizontal scaling, and caching. Thus, your application can handle increasing traffic and user loads. If you want the best MEAN stack development in the US, implement these scalability strategies. They can help you build a robust and high-performing MEAN stack application.

* Load balancing

In the first strategy, you should distribute incoming traffic across multiple servers using load balancing techniques. It enables you to prevent any single server from becoming a performance bottleneck. You can implement load balancing at different levels, such as application, network, or database level.

* Horizontal scaling 

Scale your application horizontally by adding more servers to the system as the traffic increases. You can accomplish this by using techniques such as clustering or containerization. With this type of scaling, your application can manage increased traffic by adding more resources to the system.

* Database scaling

Plan for database scalability using sharding, partitioning, or replication. For instance, sharding involves dividing the database into smaller manageable parts distributed across multiple servers. Partitioning refers to dividing the data based on particular criteria, such as range or hash, and storing them on different servers. Replication is the creation of multiple copies of the database on various servers to ensure high availability and fault tolerance.

* Auto-scaling

Finally, auto-scaling mechanisms help you automatically adjust the number of resources based on the current traffic load. Cloud-based platforms like AWS, Google Cloud, and Microsoft Azure offer auto-scaling features.
