Pitfalls encountered in practical Vue projects and solutions

Pit 1. Resource loading 404 problem occurs when accessing index.html after packaging with webpack

##Solution Solution : In index.js in config, the level of the assetsPublicPath attribute in the build object needs to be adjusted from '/' to './'

 1  build: { 2     env: require('./prod.env'), 3     index: path.resolve(__dirname, '../dist/index.html'), 4     assetsRoot: path.resolve(__dirname, '../dist'), 5     assetsSubDirectory: 'static', 6     assetsPublicPath: './', 7     productionSourceMap: false,12     productionGzip: false,13     productionGzipExtensions: ['js', 'css'],18     bundleAnalyzerReport: process.env.npm_config_report19   }

 1 dev: { 2     env: require('./dev.env'), 3     port: 8080, 4     autoOpenBrowser: true, 5     assetsSubDirectory: 'static', 6     assetsPublicPath: '/', 7     proxyTable: {}, 8     // CSS Sourcemaps off by default because relative paths are "buggy" 9     // with this option, according to the CSS-Loader README10     // ()11     // In our experience, they generally work as expected,12     // just be aware of this issue when enabling this option.13     cssSourceMap: false14   }

Reason:

The static folder of the development environment is based on The root directory, so use

'/' directly. For example, this format: http://localhost:8080/static/img/logo.png.

Everyone should know that webpack packaging will automatically package the static folder. By default, a dist folder will be generated as the root directory of the production environment file, and the static folder will be generated in dist. So the generated format should be http://localhost:8080

/dist/static/img/logo.png. It is not based on the root directory, so ‘/’ The corresponding resource must not be found.

Introduce the meaning of these attributes:

assetsRoot: The target folder path of webpack output

assetsSubDirectory: The second level of webpack compilation output Folder

assetsPublicPath: The release path of webpack compiled output, for example: /eat in www.woshichihuo.com/eat is this path

Pit 2. Use webpack After packaging, a white screen appears when accessing index.html locally, but the resources are loaded normally

Solution: Do not set the routing setting mode to history mode. The default is still hash. In the index.js file under the router folder.

1 const router = new Router({2   // mode: 'history',3   routes: [4     index,5     home6   ]7 })

If you need history mode, please refer to the vue-router official documentation:
