Vite + ESBuild error: No loader is configured for ".node" files: node_modules/fsevents/fsevents.node

Question

I am very new to ReactJS and Vite. I am working on some tutorials I have suddenly started getting below error. I have tried to re-install node_modules but didn't work. [ERROR] No loader is configured for ".node" files: node_modules/fsevents/fsevents.node

node_modules/fsevents/fsevents.js:13:23:
  13 │ const Native = require("./fsevents.node");
     ╵                        ~~~~~~~~~~~~~~~~~

/advanced-react/node_modules/esbuild/lib/main.js:1604 let error = new Error(${text}${summary});

Error: Build failed with 1 error:

Node.js v18.12.1

Below is the package.json

{
  "name": "advanced_react",
  "private": true,
  "version": "0.0.0",
  "type": "module",
  "scripts": {
    "dev": "vite",
    "build": "vite build",
    "preview": "vite preview"
  },
  "dependencies": {
    "react": "^18.2.0",
    "react-dom": "^18.2.0"
  },
  "devDependencies": {
    "@types/react": "^18.0.27",
    "@types/react-dom": "^18.0.10",
    "@vitejs/plugin-react": "^3.1.0",
    "vite": "^4.1.0",
    "node-loader": "^2.0.0"
  },
  "resolutions": {
    "**/**/fsevents": "^1.2.9"
  }
}

I am not able to figure out what I am missing in the config.

Answer 1

Add fsevents to your optimizeDeps exclude in your vite.config.js file:

  optimizeDeps: { exclude: ["fsevents"] },

Answer 2

I had the same issue, and in my case I found that vscode had accidentally imported the mergeAlias method from vitejs somewhere in my project and that had been the issue.
