Best practices for building native web applications in Go using SQLite and React

With the development of web application development, more and more developers are turning to more lightweight technology stacks to simplify application development and deployment. In this case, the Go language is an ideal choice because it provides efficient concurrent programming, fast compilation speed, and cross-platform support.

In this article, we will introduce how to build a local web application using Go language, SQLite and React, and provide best practices and suggestions.

SQLite is an embedded database engine that provides a lightweight, self-contained SQL database, making it a popular local storage solution. React is a popular JavaScript library used for building user interfaces and interactive web applications. We will use Go language to write the web server, SQLite as the data storage and React as the front-end library.

Here are some suggestions and best practices that can help us avoid some common problems when building local web applications using these technologies.

1. Use Go language to write web servers

The efficiency of Go language makes it an excellent web server language. It provides highly concurrent concurrent programming, lightweight Level threading and built-in HTTP support. The standard library of the Go language has the http package, which can easily convert a Go application into a web server.

One of the benefits of using the Go language is that it provides some good libraries and frameworks to help us build web applications. Some recommended Go libraries include:

• Gin: A web framework written in the Go language that provides functionality such as routing, middleware, and a template engine.
• Echo: Another web framework written in Go language, with functions similar to the Gin framework, but more lightweight.
• Chi: A Mux and HTTP toolbox for web programming, a lightweight, high-performance, extensible framework.

2. Choose the right SQLite driver

Before choosing a repository, we need to choose a SQLite driver that will help us interact with the SQLite database. Some recommended SQLite drivers include:

• go-sqlite3: A SQLite3 driver written in the Go language, providing a simple API and high performance.
• mattn/go-sqlite3: Another SQLite3 driver written in Go, with similar functionality to go-sqlite3 but providing better performance and error handling.

3. Build front-end UI/UX with React

React is a component-based web application library that makes developing user interfaces easier. By using React's virtual DOM, it can update DOM elements without refreshing the entire page, thus improving performance and responsiveness.

Some recommendations and best practices include:

• Use React components to build user interface and interactive elements, each with its own state and lifecycle methods.
• Use React Router for routing to achieve application navigation and user experience.
• Use a state management library such as Redux or MobX to store and manage the state of your application.

4. Let Go and React communicate

Finally, we need to ensure that Go and React can communicate to achieve data acquisition and storage. There are a few different ways to achieve this, some of which include:

• Using a RESTful API interface: By creating a RESTful API interface, you can enable the front-end to communicate with the back-end to obtain and store data.
• Using WebSocket: WebSocket allows two-way communication, so we can use it for real-time communication between front-end and back-end.
• Using GraphQL: GraphQL is a higher-level query language that allows the front-end to get exactly the data it needs, as well as send data models to the back-end.

Summary

Building local web applications using Go language, SQLite and React can bring many advantages, including efficient programming, fast performance, lightweight storage and interaction style user experience. However, when implementing these technologies, we need to follow best practices and recommendations to ensure the efficiency, reliability, and scalability of our applications.
