How to fix the 'Buffer is not defined' error in Vite

This error happens because Vite doesn’t polyfill Node.js globals like Buffer in the browser. However, some SDK dependencies (like ethers) may expect it to be available.To fix this, follow these steps:

1. Install required packages

npm install buffer
npm install --save-dev @esbuild-plugins/node-globals-polyfill @esbuild-plugins/node-modules-polyfill

Update your vite.config.ts

vite.config.ts

import { defineConfig } from 'vite'
import react from '@vitejs/plugin-react'
import { NodeGlobalsPolyfillPlugin } from '@esbuild-plugins/node-globals-polyfill'
import { NodeModulesPolyfillPlugin } from '@esbuild-plugins/node-modules-polyfill'

export default defineConfig({
  plugins: [react()],
  optimizeDeps: {
    esbuildOptions: {
      define: {
        global: 'globalThis'
      },
      plugins: [
        NodeGlobalsPolyfillPlugin({
          buffer: true
        }),
        NodeModulesPolyfillPlugin()
      ]
    }
  },
  resolve: {
    alias: {
      buffer: 'buffer'
    }
  }
})

Could not find a declaration file for module '@particle-network/universal-account-sdk'.

You might get this error when using TypeScript. To fix it, you can add a declaration in tsconfig.json.Add ./node_modules/@particle-network/universal-account-sdk/dist/index.d.ts to the paths property in tsconfig.json.

{
  "paths": {
    "@/*": ["./*"],
    "@particle-network/universal-account-sdk": ["./node_modules/@particle-network/universal-account-sdk/dist/index.d.ts"]
  }
}

This will solve the declaration error.
