Sanity Check

• If this is a build issue, I have included my build config. If this is a runtime issue, I have included reproduction steps and/or a Minimal, Reproducible Example.

@Elliott-Green I was able to get it up and running with the following steps:
First, ensure you have @rollup/plugin-commonjs installed:

npm install @rollup/plugin-commonjs --save-dev

Then, include it in your Vite configuration:

import commonjs from '@rollup/plugin-commonjs';

// Inside your Vite config
const config: UserConfig = {
  plugins: [
    sveltekit(),
    commonjs({
      include: /node_modules/ // Only transpile CommonJS modules from node_modules
    }),
    // Your other plugins...
  ],
  // Your other config options...
};

Can you give that a try and let me know?

PR to get the example working : #2086

[Elliott-Green]

Hey @Adamj1232,

Thanks for looking into this.

I've picked the changes up from #2086 but alas, I'm still having the same issues.

Did you ever get a vercel deployment out for 2086? build+preview work locally, so looks ok, but will error on vercel.

Had a few other local issues that I managed to resolve, would recommend these packages get updated as they've been patched to work nicely with commonJS - or something, I have no idea, this side of js is a black box to me.

4:05:42 PM [vite] Error when evaluating SSR module /node_modules/@web3-onboard/core/node_modules/svelte-i18n/dist/runtime.esm.js: failed to import "intl-messageformat"
|- SyntaxError: [vite] Named export 'IntlMessageFormat' not found. The requested module 'intl-messageformat' is a CommonJS module, which may not support all module.exports as named exports.
CommonJS modules can always be imported via the default export, for example using:

import pkg from 'intl-messageformat';
const {IntlMessageFormat} = pkg;

By overriding some of the package versions, I am able to resolve some of my build issues like:

"overrides": {
		"@web3-onboard/core": {
			"svelte-i18n": "^4.0.0",
			"intl-messageformat": "^10.5.1",
			"bnc-sdk": {
				"rxjs": "^7.8.1"
			}
		},
		"@web3-onboard/coinbase": {
			"@coinbase/wallet-sdk": {
				"rxjs": "^7.8.1"
			}
		},
		// Not sure about this one, trying to fix atm
		"@web3-onboard/trezor": {
			"@ethereumjs/tx": "^5.2.1",
			"eth-crypto": {
				"@ethereumjs/tx": "^5.2.1"
			}
		}
