Before bumping the Node.js version to higher version in your package.json, you should consider the following:

Check Node.js Release Schedule:

The Node.js release schedule is available at https://nodejs.org/en/about/releases/. You should use a version that is currently maintained.

Check Dependencies Compatibility:

Ensure that all your dependencies are compatible with the new Node.js version. You can check the engines field in the package.json of your dependencies, or check their documentation.

Update Your Development Environment:

Make sure that your local development environment is running the same Node.js version. You can use a version manager like nvm to manage multiple Node.js versions on your machine.

There are some methods to check this but you also can use this script to check all packages' engine

import fs from 'fs'
import { exec } from 'child_process'
const packageJson = JSON.parse(fs.readFileSync('package.json', 'utf8'))

const allDependencies = { ...packageJson.dependencies, ...packageJson.devDependencies }

for (const dependency in allDependencies) {
  exec(`npm view ${dependency} engines`, (error, stdout, stderr) => {
    if (error) {
      console.error(`exec error: ${error}`)
      return
    }
    console.log(`Engines for ${dependency}: ${stdout}`)
  })
}

Update Your CI/CD Pipeline:

If you have a continuous integration/continuous deployment (CI/CD) pipeline, make sure to update the Node.js version there as well.

Inform Your Team:

If you're working in a team, inform everyone about the Node.js version change so they can update their local environments.

Test Your Application:

After updating the Node.js version, thoroughly test your application to catch any potential issues caused by the version change.

Here's how you can update the Node.js version to 20 in your package.json:

"engines": {
  "node": ">=20"
}

Thank you for taking the time to read the article. I would love to hear your approach and tips on upgrading the node.
