Best Practices for Building Modern Web Applications with Go and Nunjucks

Web application development is becoming increasingly complex and diverse, and programmers need to use efficient technologies and best practices to build modern Web application. In this article, we’ll cover best practices for building modern web applications using Go and Nunjucks.

Go is a fast, reliable and modern programming language that is particularly suitable for building web applications. Go's concurrency features, beautiful syntax, high performance, and easy-to-learn structure make it an excellent choice. Nunjucks is a JavaScript-based template engine that helps us build efficient web applications.

The following are best practices for building modern web applications using Go and Nunjucks.

1. MVC structure

It is very important to use the structure of MVC (Model-View-Controller) to build web applications. This structure helps developers divide the application into three main parts: models, views, and controllers. The model is the application's data and business rules, the view is the application's user interface, and the controller is part of the application's business logic and user interaction.

In Go, we can use Gin as a web framework to implement the MVC structure. Gin helps us handle HTTP requests and responses easily. At the same time, we can use Nunjucks to render the view.

2. RESTful API

RESTful API is another important component in building web applications. RESTful API is an architectural style that decomposes web applications into resources, and each resource corresponds to a URI (Uniform Resource Identifier). We can use the HTTP protocol to perform different operations on these resources, such as GET, POST, PUT and DELETE, etc.

In Go, we can use the Gin framework to create RESTful APIs. Gin provides some useful methods for request and response processing, such as JSON, XML, Form and Query, etc.

3. Database

The database is an essential part of the web application. We can use a relational database or a non-relational database to store application data. In Go, we can use Gorm as an object-relational mapping (ORM) tool to manage databases.

Gorm provides some useful features such as transaction processing, query builder and preloading. At the same time, we can use Gorm to interact with different types of databases, such as MySQL, PostgreSQL, SQLite, etc. If you are building a non-relational database, you can use an open source database such as MongoDB or Cassandra.

4. Deployment

Deploying a web application is an important step. We can use Docker and Kubernetes to deploy web applications. Docker is a containerization platform that can help us easily package web applications into container images. Kubernetes is a container orchestration system that helps us manage containerized applications.

Using Docker and Kubernetes can help us easily deploy and scale web applications. We can use Docker to build and push container images, and then use Kubernetes to deploy and manage containers.

Conclusion

Building modern web applications using Go and Nunjucks requires following some best practices. Use MVC structure to separate different parts of the application, use RESTful API to simplify the interface of the application, use ORM tools to easily manage databases, and use Docker and Kubernetes to easily deploy and scale applications. Using these best practices can help us build efficient, stable and scalable web applications.
