Webpack Errors - Cannot Resolve 'crypto', 'http', and 'https' in Vue.js - node.js

Question

Question Background
I'm trying to add Wallet Connect to our project(Vue.js), form here: https://docs.walletconnect.com/quick-start/dapps/web3-provider, I used this command to install it.
import it in my js file
import Web3 from 'web3'
import WalletConnectProvider from '#walletconnect/web3-provider'
it shows those errors:
ERROR Failed to compile with 7 errors
These dependencies were not found:
* crypto in ./node_modules/eth-lib/lib/bytes.js, ./node_modules/web3-eth-accounts/lib/index.js and 1 other
* http in ./node_modules/xhr2-cookies/dist/xml-http-request.js
* https in ./node_modules/xhr2-cookies/dist/xml-http-request.js
To install them, you can run: npm install --save crypto http https
Try
I install those packages.
npm i crypto-browserify
npm i https-browserify
npm i stream-http
Then edit my vue.config.js files:
resolve: {
fallback: {
crypto: require.resolve('crypto-browserify'),
http: require.resolve('stream-http'),
https: require.resolve('https-browserify'),
},
},
and the errors becomes:
WebpackOptionsValidationError: Invalid configuration object. Webpack has been initialised using a configuration object that does not match the API schema.
configuration.resolve has an unknown property 'fallback'.
These properties are valid:
object { alias?, aliasFields?, cachePredicate?, cacheWithContext?, concord?, descriptionFiles?, enforceExtension?, enforceModuleExtension?, extensions?, fileSystem?, mainFields?, mainFiles?, moduleExtensions?, modules?, plugins?, resolver?, symlinks?, unsafeCache?, useSyncFileSystemCalls? }
This is my package.json file look like:
{
"dependencies": {
"#walletconnect/web3-provider": "^1.7.8",
"crypto-browserify": "^3.12.0",
"https-browserify": "^1.0.0",
"os": "^0.1.2",
"stream": "^0.0.2",
"stream-http": "^3.2.0",
"vue": "^2.6.10",
"web3": "^1.7.3",
},
"devDependencies": {
"#vue/cli-service": "^3.7.0",
"webpack": "^4.39.3",
"webpack-bundle-analyzer": "^3.6.0",
"webpack-dev-server": "^3.11.2",
"webpack-merge": "^4.2.1",
"webpack-node-externals": "^1.7.2",
"webpack-plugin-hash-output": "^3.2.1",
"webpack-spritesmith": "^1.0.1",
}
}
and my node version is v10.24.1, the version still can't be upgraded temporarily.
v10.24.1
As seen from the above, I have installed the suggested packages from the errors (crypto-browserify, stream-http, and https-browserify) and have included them in the vue.config.js.
How can I solve this?

Answer 1

You are using Webpack 4. The fallback option is only available from Webpack >=5.0.0 onwards.
For Webpack 4, consider using alias option.
