Go: Frameworks

In this article we explain the importance of web frameworks in software developement. Go is a general purpose language, but if you use it for web developement, you should use a framework. Let's begin our research:

What is it?

A web framework is a tool that simplifies the process of building web applications by providing a set of libraries and conventions that make building a web application more efficient and organized. In the case of Go, a web framework like Gin, Echo, or Beego provides a set of predefined functions and structs for handling HTTP requests and responses, routing, middleware, templating, and database integration. This allows developers to focus on writing business logic instead of dealing with low-level details of HTTP protocol or database connectivity.

Reasons

Here are some reasons why we need a web framework for Go:

Efficiency: Frameworks provide a way to streamline the development process by providing reusable components that allow developers to start building quickly and efficiently.
Standardization: Frameworks typically enforce coding conventions and organizational structures that help maintain consistency across projects and teams.
Security: Many frameworks come with built-in security features that help protect against common web application attacks like cross-site scripting (XSS), SQL injection, and CSRF.
Scalability: Frameworks typically provide patterns and tools that are optimized for building scalable applications that can handle high traffic and complex processing tasks.

Overall, using a framework in Go can save time and effort while also providing a more secure, standardized, and scalable approach to building web applications.

Alternatives

Here are some alternative frameworks for the Go language, along with a brief description of each. For details, follow the link and visit the homepage fo each of these frameworks:

1. Gin

Gin is a popular web framework for Go that is known for its speed and ease of use. It provides a minimalistic approach to building web applications and APIs, and includes features such as routing, middleware, and error handling.

Each of these frameworks has its own strengths and weaknesses, so you should choose the one that best fits your needs and preferences.

How it works?

Go web frameworks provide a set of tools and abstractions for building web applications or microservices written in the Go programming language. A typical Go web framework consists of the following components:

Routing

Routing is the process of matching incoming requests to their respective handler functions. A good Go web framework has a router, which accepts an HTTP request and maps it to the appropriate controller action, based on the request URL, HTTP method, and other factors.

Middleware

Middleware are code snippets that execute before or after a request is handled, allowing for processing of authentication, logging, caching, and other functionality. You can chain middleware functions, using them in a particular order to create a unified processing pipeline.

Controllers/Handlers

Controllers or handlers are functions that receive an HTTP request, perform some action based on the request, and then send back an HTTP response. In a Go web framework, a controller is typically a method of a struct that is attached to a specific HTTP route.

View/Template Engine

A view or template engine is responsible for generating HTML or other responses to an incoming request. Go frameworks usually support various view engines for converting data into HTML, such as Go templates, Jet Templates, or HTML templates.

Database Connection and ORM

Go web frameworks usually provide interfaces and drivers for working with different database types, as well as integrations with popular ORMs like GORM or SQLBoiler.

Go web frameworks simplify the development process by providing pre-built components and tools for managing different aspects of web application development. This reduces the amount of work required for a developer to build a complex web application from scratch.

Deployment

There are a number of different ways to deploy a website created with a web framework for Go, depending on your needs and preferences. Here are a few options to consider:

1. Deploy to a cloud platform:

You can choose to deploy your application to a cloud platform such as Amazon Web Services (AWS), Google Cloud Platform (GCP), or Microsoft Azure, where you can take advantage of the platform's infrastructure and features, such as load balancing and auto-scaling. Most of these cloud platforms offer different options to deploy applications, including virtual machines (VMs), containers, or serverless functions.

2. Deploy to a hosting service:

Another option is to deploy your application to a hosting service such as Heroku, DigitalOcean or Linode, which allows you to deploy your application quickly without worrying about scaling, security, and infrastructure. These hosting services often provide a user-friendly interface to deploy your application.

3. Deploy to a dedicated server:

If you need more control over the infrastructure and configurations, you can choose to deploy your application to a dedicated server, either owned or rented. You'll be in charge of managing the server, installing the necessary software, and securing the machine.

4. Deploy using a deployment tool:

Another option is to use a deployment tool such as Docker, Kubernetes, or Jenkins. These tools can help you automate the deployment process, create and manage containers, maintain application state and rollbacks, and simplify scaling and autoscaling.

No matter which option you choose, you'll need to choose a method that works best for your application and infrastructure preferences.

Front End

A front-end framework is a collection of pre-designed HTML, CSS, and JavaScript code that assist developers in building user interfaces for web applications. These frameworks make it easier and faster to create a visually appealing and responsive user interface without having to build everything from scratch.

Go web frameworks, on the other hand, provide functionality for building the backend of a web application. They serve as a web server, handle HTTP requests and return responses. They can also interface with databases or other web services, allowing for the creation of powerful and complex web applications.

While a Go Web Framework can create the user interface entirely through HTML and CSS, it can be tedious, especially when dealing with complex applications. In this scenario, a frontend framework such as React, Vue.js, or Angular can be used to create a flexible and responsive UI with ease. Front-end frameworks generate HTML, CSS, and JavaScript that can be directly rendered by the browser and interact with the backend through RESTful APIs.

Integrating a front-end framework with a Go web framework can result in a more robust and scalable web application. The Web Framework will handle the back-end, and the front-end framework will handle the user interface. They can also communicate with each other by RESTful APIs. This separation allows developers to work on different parts of the application concurrently and enables rapid development and iteration.

Go + Vue

Go framework and Vue.js can be a great combination for building an SPA (Single Page Application). Go is a fast, efficient, and highly-performant web framework that is suitable for building large-scale web applications. Vue is a progressive JavaScript framework that is optimized for building user interfaces, especially SPAs.

Go is typically used as a backend server, while Vue is used in the frontend to create a highly interactive and responsive user experience. The combination of these two frameworks can result in a robust, scalable, and efficient web application.

Vue.js provides a wide range of features such as state management, routing, and component-based architecture, which makes it easy to create highly-focused and reusable code. Go, on the other hand, is suitable for RESTful API development, which means that it can work effectively with Vue.js to create a seamless data flow between the frontend and the backend.

One of the advantages of using Go and Vue.js is that both have a relatively small learning curve, which means they are easy to learn and understand. This can lead to faster development times, allowing developers to get a product to market quickly.

Overall, Go framework and Vue.js make an excellent combination in creating high-performance Single Page Applications. The respective strengths of the frameworks can result in a robust and efficient web application that can be developed quickly and easily.

Go + React

Go framework and React can also be a great combination for building SPA (Single Page Application). Go is a backend web framework that is designed for scalability, reliability, and high-performance, while React is a frontend JavaScript library that is optimized for building user interfaces.

Go is responsible for fetching and processing data from the server and React renders the UI components based on the received data. React makes it easy to create reusable components, allowing for a more efficient development process. Go's concurrency model ensures that the application can handle a large number of requests while maintaining high performance.

One of the advantages of using Go and React is that both are open-source frameworks with a large community of developers. This means that there is an abundance of resources available for learning and resolving issues that may arise during development.

In terms of performance, Go and React can handle heavy server-side processing and rendering of complex UI components and provide fast response times. This makes Go and React suitable for building complex and high-performance applications.

However, the learning curve for React may be steeper than Vue.js, which can impact development times for developers new to React.

Overall, Go framework and React can work together to create a performant and scalable SPA that can handle complex data processing and rendering. It may take more time for developers to master React, but the effort can pay off in the form of high-performance applications.

Go + Svelte

Go + Flutter

Using Go Framework with Flutter can be a great option for building both Single Page Applications (SPAs) and Mobile Apps. Go can serve as the backend language for the application, while Flutter can provide a single codebase for building web and mobile frontends.

Here are some advantages and considerations for using this combination for SPA and mobile apps:

When it comes to the advantages of Go and Svelte over Dart and Flutter, it mainly depends on the use case and the project requirements. If you're building a web application that needs high-performance, scalability, and reliability, then Go and Svelte can be a great choice.

However, if you are targeting mobile devices, then Dart and Flutter might be a better choice as it provides a native experience and is specially designed for creating high-performance mobile apps.

Overall, both combinations have their strengths and weaknesses, and the choice between the two depends on the specific requirements and goals of the project.

Conclusion:

There are two choices to build a website using Go:

To make a website that is server side generated using templates. This require only Go Framework.
To make a repsonsive website using a front-end technology + Go Framework back-end.

First one is more easy to make but is not so fancy. Second one is very advanced, require you to know front-end developement very well but it can lead to spectacular applications.
