Detailed explanation of the configuration scheme of the Vue project

With the continuous development of front-end technology, Vue has become one of the leaders in front-end frameworks. When using Vue to develop projects, we need to configure the project to adapt to different working environments and needs. This article will discuss the configuration scheme of the Vue project in detail.

1. Basic configuration of the Vue project

1. vue.config.js file

In the root directory of the Vue project, we can create a file named It is the configuration file of vue.config.js. This file is used to configure basic information of the Vue project, such as the project's output path, publicPath, proxy and webpack configuration, etc.

2. .env file

We can store the environment variables required by the project by creating different .env files. For example, we can create .env.development, .env.pre-production and .env.production files to store environment variables for development, pre-production and production environments respectively.

2. Debug configuration of Vue project

1. Source Map

Through Source Map, we can map the compiled code to the original code. In this way, it will be more convenient when we debug the project. We can turn on Source Map in vue.config.js through the following code:

module.exports = {
  configureWebpack: {
    devtool: 'source-map'
  }
}

2. DevTools

Vue development tools provide developers with a lot of conveniences during project debugging. Time is also an essential part. We can open the Vue development tool by adding the following code to the project:

Vue.config.devtools = true

3. Optimized configuration of the Vue project

The optimized configuration of the Vue project is mainly to improve the performance and experience of the project.

1. Code Splitting

By splitting the application into small chunks, we can reduce the initial load time of the application. Vue projects can use the code splitting feature in Webpack to achieve this goal. We can configure it in vue.config.js:

module.exports = {
  configureWebpack: {
    optimization: {
      splitChunks: {
        chunks: 'all'
      }
    }
  }
}

2. Image compression

Image is a resource that takes up a lot of traffic in a page. By compressing the image, We can reduce page load time. We can use the following command to install image-webpack-loader:

npm install image-webpack-loader --save-dev

and then configure it in vue.config.js:

module.exports = {
  chainWebpack: config => {
    config.module
      .rule('images')
      .use('image-webpack-loader')
      .loader('image-webpack-loader')
      .options({
        bypassOnDebug: true
      })
      .end()
  }
}

3. Keep-Alive

In Vue 2.x version, we can use the Keep-Alive component to cache the state of the component to improve performance. We can add the following code to the components that need to be cached:

<keep-alive>
  <component></component>
</keep-alive>

4. Security configuration of the Vue project

1. CSP

Content-Security-Policy (Content Security Policy) is an HTTP header used to prevent cross-site scripting and data injection attacks. We can configure CSP in vue.config.js:

module.exports = {
  devServer: {
    headers: {
      'Content-Security-Policy': "default-src 'self'"
    }
  }
}

2. HTTPS

In the Vue project, we can ensure the security of the website by enabling HTTPS. We can configure HTTPS in vue.config.js:

module.exports = {
  devServer: {
    https: true
  }
}

The above are some basic solutions and common methods for Vue project configuration. In actual development, we can select and configure different solutions according to the specific conditions of the project.
