Best practices for building scalable web applications using Go and Redux

As web applications continue to develop, more and more companies are beginning to shift from traditional back-end rendering to front-end rendering. In order to achieve this goal, many enterprises adopt Go language and Redux in web applications. In this article, we will discuss the best practices for building scalable web applications using these two technologies.

1. Familiar with Go language

Go language is an open source programming language developed by Google. It is simple, efficient, and safe, and can be used to build highly concurrent web applications. When using Go language to build web applications, you need to be familiar with the following key points:

• Be familiar with HTTP requests and responses
• Be familiar with the net/http module in the Go standard library, especially the net/http module in the Go standard library It’s the use of routing and middleware
• Be familiar with Go’s concurrency model, including Goroutines and Channels
• Master how to interact with the database

2. Understand Redux

Redux is a JavaScript library used to manage application state for web applications. It ensures application state consistency by organizing application state into a single data source and limiting changes to application state to pure functions. The main elements of Redux are Actions, Reducers and Store.

• Action: An object that describes events that trigger application state changes.
• Reducer: A pure function that describes how to change the application state and return the new state.
• Store: Store application state in a centralized data source and manage all changes to application state.

3. Integrating Go and Redux

The best way to integrate Go and Redux is to use Go to organize the backend of the application and integrate it through API endpoints Application state is sent to the front-end Redux Store. Here are some best practices:

• Use Go's httprouter routing library to organize API endpoints.
• Map each API endpoint to a Go HandlerFunc function that handles the request and returns a JSON representation of the application state.
• Use Redux Store as a single data source for web applications and obtain application status from API endpoint during Store initialization process.
• Use Redux middleware to send asynchronous API requests, map responses to Actions, and use Reducers to change application state.

4. Implementing Proper Routing

It is very important to manage application state by implementing proper routing. We can organize application state into a hierarchy and define a unique URL for each state component. When the user navigates to a specific URL, the application displays the component associated with that URL and sends an Action to the Redux Store to change the application state. Here are some best practices:

• Use the React-Router library to organize the front-end routing of your web application.
• Organize application state according to different parts of the URL, associating each state component with a separate URL.
• Map each state component to the Redux Store so that they can listen to state changes in the Store and update themselves.

5. Saving user information securely

Web applications often need to save user information, such as usernames and passwords. Keeping this information securely is critical to prevent bad actors from accessing sensitive information. Here are some best practices:

• Use the https protocol to ensure that data transfers between the web application and the user are encrypted.
• For user information, use a hash function for encryption to ensure that the encrypted hash value is stored in the database instead of the original password.
• Before storing user information, use data validation to ensure that the entered data meets requirements, such as that the entered username and password length meet the minimum requirements, and that the entered email is in the correct format.

Summary

The Go language and Redux are both excellent technologies for supporting scalable web applications. Understanding the best practices for both technologies can help you better implement them when building scalable web applications. By combining these technologies into a unified application, you can achieve highly scalable web applications while maintaining maintainability and security.
