vite 使用web3，@walletconnect/web3-provider 或者其他库，出了一系列vite的相关问题

// example
Uncaught ReferenceError: process is not defined
Uncaught ReferenceError: global is not defined
Uncaught ReferenceError: Buffer is not defined
...........

最终解决方案

在 index.html添加

<script>window.global = window;</script>
<script type="module">
    import process from "process";
    import { Buffer } from "buffer";
    import EventEmitter from "events";
    
    window.Buffer = Buffer;
    window.process = process;
    window.EventEmitter = EventEmitter;
</script>

在vite.config.ts

import vue from '@vitejs/plugin-vue'

export default {
  resolve: {
    alias: {
      process: "process/browser",
      stream: "stream-browserify",
      zlib: "browserify-zlib",
      util: 'util'
    }
  },
  plugins: [
    vue(),
  ]
}

添加这些依赖项 browserify-zlib, events, process, stream-browserify,util

最终完美解决

最新更新

build打包完，还是发现walletconnect的包有点问题。require,buffer之类的问题。
苦寻良久，解决方案
在vite.config.ts中添加如下配置

//vite.config.ts
  import  inject  from  '@rollup/plugin-inject'

  build: {
    rollupOptions: {
      // @ts-ignore
      plugins: [inject({ Buffer: ['buffer', 'Buffer'] })],
    },
    commonjsOptions: {
      transformMixedEsModules: true,
    },
  },
