Optimize website performance and loading speed with Webman

Use Webman to optimize website performance and loading speed

With the continuous development of Internet technology, people have higher and higher requirements for website performance and loading speed. A fast-loading website provides a better user experience and improves search engine rankings. This article will introduce how to use Webman to optimize the performance and loading speed of your website.

Webman is an open source website optimization tool that can automatically help you implement some optimization techniques, including compressing and merging static resources, using caching, lazy loading, etc. The following will introduce step by step how to use Webman for website performance optimization.

The first step is to install Webman. First, you need to create a folder called .webman in the root directory of your website. Then, run the following command in the command line to install Webman.

npm install webman

After the installation is complete, you can use various functions of Webman in your project.

The second step is to configure Webman. Create a file called .webman.json in the root directory of your website and add the following content in it.

{
  "tasks": [
    {
      "type": "compress",
      "files": "css/*.css"
    },
    {
      "type": "merge",
      "files": [
        "js/*.js"
      ],
      "output": "js/all.js"
    },
    {
      "type": "cache",
      "files": [
        "*.html",
        "*.css",
        "*.js",
        "*.png",
        "*.jpg"
      ]
    },
    {
      "type": "lazyload",
      "files": [
        "*.jpg",
        "*.png"
      ]
    }
  ]
}

The above configuration file contains four tasks: compressing CSS, merging JS, using caching and lazy loading of images. You can modify the configuration of these tasks according to your needs.

The third step is to run Webman. Run the following command in the command line to start Webman.

npx webman

After running, Webman will automatically optimize your website and output corresponding log information.

It is worth noting that Webman does not directly modify your source code files, but creates a folder named .webman-cache to store the optimized files, and then rewrites the URL. to use these optimized files.

After the above configuration and operation, the performance and loading speed of your website will be improved. You can use the log information provided by Webman to monitor the performance indicators of your website and make further optimizations as needed.

In addition to the above optimization technology, Webman also provides other functions, such as automatically compressing images, using CDN acceleration, etc. You can check Webman's official documentation to learn more about its functions and usage.

To sum up, using Webman can help us optimize the performance and loading speed of the website more easily. By properly configuring and running Webman, we can compress and merge static resources, use optimization techniques such as caching and delayed loading. I hope this article can provide some help for you to understand and use Webman to optimize website performance.

Code Example:

{
  "tasks": [
    {
      "type": "compress",
      "files": "css/*.css"
    },
    {
      "type": "merge",
      "files": [
        "js/*.js"
      ],
      "output": "js/all.js"
    },
    {
      "type": "cache",
      "files": [
        "*.html",
        "*.css",
        "*.js",
        "*.png",
        "*.jpg"
      ]
    },
    {
      "type": "lazyload",
      "files": [
        "*.jpg",
        "*.png"
      ]
    }
  ]
}

The above code example shows the tasks in the Webman configuration file. The compress task is used to compress CSS files, the merge task is used to merge JS files, the cache task is used to use caching, and the lazyload task is used to delay loading images. You can modify the configuration of these tasks according to your needs.
