Research direction

Start by reproducing the failure with npm run prod and inspect the webpack configuration and the application code that imports jsonwebtoken. Review the reported crypto and stream resolution errors to determine whether this package is intended for the browser bundle. Done means the project’s production build handles the dependency appropriately without these module-resolution errors.

Description

When I used "npm run prod" to build npm it shows the following error. Please guide me to solve the problem.

ERROR in ./node_modules/jsonwebtoken/sign.js 6:57-74
Module not found: Error: Can't resolve 'crypto' in '/var/www/html/inb-platform/node_modules/jsonwebtoken'

BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.
This is no longer the case. Verify if you need this module and configure a polyfill for it.

If you want to include a polyfill, you need to:
	- add a fallback 'resolve.fallback: { "crypto": require.resolve("crypto-browserify") }'
	- install 'crypto-browserify'
If you don't want to include a polyfill, you can use an empty module like this:
	resolve.fallback: { "crypto": false }
