node.js - 在 nextJS (next.config.js) 中设置 webpack 配置

Question

我正在使用 NextJS 并使用 react-data-export生成xls文件的插件。在描述中它说:

This library uses file-saver and xlsx and usingjson-loader will do the magic for you.

///webpack.config.js
vendor: [
        .....
        'xlsx',
        'file-saver'
],
.....
node: {fs: 'empty'},
externals: [
    {'./cptable': 'var cptable'},
    {'./jszip': 'jszip'}
 ]

但我不知道如何实现它并得到这样的错误:

The static directory has been deprecated in favor of the public directory. https://err.sh/vercel/next.js/static-dir-deprecated

我遇到了同样的问题，我的解决方案是这样的:

1. 安装这个包(如果你安装了，忽略这个)

npm install file-saver --save

npm install xlsx

npm install --save-dev json-loader

1. 将此添加到您的nextjs.config.js

    const path = require('path')

    module.exports = {
      ...

      //Add this lines
      webpack: (config, { isServer }) => {
        // Fixes npm packages that depend on `fs` module
        if (!isServer) {
          config.node = {
            fs: 'empty'
          }
        }
    
        return config
      }
    
    }
