從 CRA（創建反應應用程序）遷移到 vite 后，未定義緩沖區

Question

在聲明並完成所有配置文件后，當我啟動服務器時，我得到 Buffer not defined 並且錯誤指向 npm 模塊。 Uncaught ReferenceError: Buffer is not definedat node_modules/jsesc/jsesc.js

Answer 1

您可以在 vite.config.ts、index.html 和添加包中進行以下更改以解決此問題

1.安裝包

yarn add process util buffer events
yarn add @esbuild-plugins/node-modules-polyfill

2.更新vite.config

import GlobalPolyFill from "@esbuild-plugins/node-globals-polyfill";
import react from "@vitejs/plugin-react";
import { resolve } from "path";
import rollupNodePolyFill from "rollup-plugin-node-polyfills";
import { defineConfig } from "vite";

export default defineConfig({
    plugins: [react()],
    optimizeDeps: {
        esbuildOptions: {
            define: {
                global: "globalThis",
            },
            plugins: [
                GlobalPolyFill({
                    process: true,
                    buffer: true,
                }),
            ],
        },
    },
    resolve: {
        alias: {
            process: "process/browser",
            stream: "stream-browserify",
            zlib: "browserify-zlib",
            util: "util",
        },
    },
});

3.更新索引.html

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8" />
  <link rel="icon" type="image/svg+xml" href="/src/assets/images/favicon.svg" />
  <meta name="viewport" content="width=device-width, initial-scale=1.0" />
  <title>Vite App</title>
  <script>
    window.global = window;
  </script>
  <script type="module">
    import process from "process";
    import EventEmitter from "events";
    import {Buffer} from "buffer";
    window.Buffer = Buffer;
    window.process = process;
    window.EventEmitter = EventEmitter;
  </script>
</head>

<body>
  <div id="root"></div>
  <script type="module" src="./src/index.js"></script>
</body>
</html>
