Vitest is a next-generation JavaScript testing framework powered by Vite. It’s an excellent alternative to Jest, offering native TypeScript support, a fast setup, and solid performance. However, while it has an experimental headless browser, it’s not ideal for advanced scenarios like running SEO audits in CI/CD pipelines. Instead, we can pair Vitest with Pupetter, a more mature tool for headless browser automation.

When creating this template project, I saw that I had to set up the server manually and I used gofiber as it has express-like functionalities, and as a MERN stack developer, I found it very easy to use. Once I thought to make a server-project generator in Express as well, but they already have one, it is called express-generator. Then I thought there might be the same thing for Fiber as well. But when I searched in GitHub with the topic:go-backend-template, I only found pre-made templates that you can clone and use for your projects. That's when I decided to give it a shot.

Project mention: Go vs Node.js vs PHP: Which Framework Outperforms the Other in Speed and Efficiency? | dev.to | 2025-01-20
echo vs. fasthttp Selection: If the echo framework has been decided to be used, it is not recommended to consider fasthttp anymore. Although echo supported fasthttp in version 2, the author of echo explained the reasons for giving up in https://github.com/labstack/echo/issues/665, mainly to maintain the simplicity of the framework and community compatibility, and to use the standard library as much as possible. This enables echo to better integrate with the community ecosystem while maintaining high performance.
