ReferenceError: Can't find variable: global

[kotsmile]

My build vite vue3 and packages vue-router and pinia. I have tried a lot variants and even the simplest one throws the same error every time. When I try to initialize WallectConnectProvider like that:

import WalletconnectProvider from '@walletconnect/web3-provider'

async function connect() {
  const config = {97: 'https://data-seed-prebsc-1-s1.binance.org:8545/'}
  const wc = new WalletconnectProvider({rpc: config})
  // await wc.enable()
}

Page immediately crushes with error: ReferenceError: Can't find variable: global.

Seems like this problem appeared on vue3 + vite. I researched a lot and found that the problem possible on walletconnect lib side

Similar issue here using Vite with React.

After following that message in the console, it tells me:
Could not load content for http://localhost:3000/node_modules/@walletconnect/socket-transport/src/index.ts (HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE)

Looking at /node_modules/@walletconnect/socket-transport, there is no 'src' folder to begin with nor does it install it.

Did you have any luck?

I was able to make the umd build work (via unpkg) with remix

[wong2]

@gaspardip How did u do that?

@gaspardip How did u do that?

Since @walletconnect/web3-provider won't compile with Remix (esbuild) for some reason, I figured I could just use the UMD build from unpkg. Just added https://unpkg.com/@walletconnect/[email protected]/dist/umd/index.min.js to my scripts and I was then able to use window.WalletConnectProvider.default normally in my code.

@esbuild-plugins/node-globals-polyfill was able to help me out with global is not defined and Buffer is not defined here is related comment plouc/nivo#1455 (comment)

This error also happens with Svelte. Is this something that has to be fixed by Svelte+Vite, or can something be done from WalletConnect side?

After a bit of digging, this seems to be an old issue (almost 2 years old): #341
So it appears we can't use this library with any modern bundler apparently.
Is this in the roadmap to be fixed @pedrouid ? seems it should be a high priority issue. I think WalletConnect has the best UX/Protocol for wallets, but can't use it at all the moment.

[cryptoembrace]

ahhh so hoped to find a solution here, too bad we can't use it with Vite
I really hope they will fix it anytime soon

import WalletConnectProvider from '@walletconnect/web3-provider/dist/umd/index.min.js'
import QRCodeModal from '@walletconnect/qrcode-modal/dist/umd/index.min.js'

try this

As @armgit5 mentioned, this currently works: https://stackoverflow.com/questions/70714690/buffer-is-not-defined-in-react-vite

npm i @esbuild-plugins/node-globals-polyfill

Inside your vite.config.js file:

Import the package:

import { NodeGlobalsPolyfillPlugin } from '@esbuild-plugins/node-globals-polyfill'

And then add optimizeDeps to the config:

export default defineConfig({
    // ...other config settings
    optimizeDeps: {
        esbuildOptions: {
            // Node.js global to browser globalThis
            define: {
                global: 'globalThis'
            },
            // Enable esbuild polyfill plugins
            plugins: [
                NodeGlobalsPolyfillPlugin({
                    buffer: true
                })
            ]
        }
    }
})

Currently working as of 8/2/22 - Vite(2.9.12) / Vue 3(3.2.37)

esbuildOptions: {
// Node.js global to browser globalThis
define: {
global: 'globalThis'
},
// Enable esbuild polyfill plugins
plugins: [
NodeGlobalsPolyfillPlugin({
buffer: true
})
]
}

For the this results in the following build error:

✘ [ERROR] The injected path "/{my_app_path}/node_modules/@esbuild-plugins/node-globals-polyfill/_virtual-process-polyfill_.js" cannot be marked as external

// Node.js global to browser globalThis
define: {
global: 'globalThis'
},
// Enable esbuild polyfill plugins

}

Are you found the solution?, I have the same error

@thxForu does @FounderCasey's fix work for you?
