在 nextJS (next.config.js) 中設置 webpack 配置

Question

我正在使用 NextJS 並使用react-data-export插件生成 xls 文件。 在描述中它說：

該庫使用文件保護程序和xlsx ，使用json-loader將為您帶來魔力。

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

但我不知道如何實現它並得到這樣的錯誤：

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

我有同樣的問題，我的解決方案是這樣的：

1. 安裝這個包（如果你安裝了，忽略這個）

npm install file-saver --save

npm 安裝 xlsx

npm install --save-dev json-loader

2. 將此添加到您的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
      }
    
    }
