ERROR in ./node_modules/jsonwebtoken/sign.js 18:4–21Module not found: Error: Can’t resolve ‘crypto’ in ‘/Users/bounphonekosada/Documents/course/vue-ts/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 }

It seems like you are trying to use the jsonwebtoken package in a Vue project with Webpack, but you're encountering an error because the crypto module, which is a Node.js core module, is not found.

Webpack 5 no longer automatically includes polyfills for Node.js core modules. To fix this issue, you need to configure a polyfill for the crypto module. Here's what you should do:

• Install the crypto-browserify package, which provides a browser-compatible version of the crypto module:

npm install --save crypto-browserify

• Update your webpack configuration file (usually webpack.config.js or vue.config.js if you're using Vue CLI) to include a fallback for the crypto module. Add the following code to the resolve object:

resolve: {
  // ...
  fallback: {
    "crypto": require.resolve("crypto-browserify")
  }
}

For example, if you’re using Vue CLI, your vue.config.js file should look like this:

module.exports = {
  configureWebpack: {
    resolve: {
      fallback: {
        "crypto": require.resolve("crypto-browserify")
      }
    }
  }
}

Save the changes, and then try running your application again. The issue should be resolved, and you should be able to use jsonwebtoken in your project without any errors.
