Hey there! This error pops up because the compression module — which webpack-dev-server relies on for its functionality — isn’t installed in your project’s dependencies. Here’s how to fix it step by step:

• First, install the missing module
  Navigate to your project’s root directory in the terminal, then run one of these commands based on your package manager:

  • For npm: npm install compression --save-dev
  • For Yarn: yarn add compression --dev

• If the error persists after installation
  Sometimes cached dependencies can cause issues. Try these steps:

  1. Delete your node_modules folder and lock file:
     • On macOS/Linux: rm -rf node_modules package-lock.json
     • On Windows Command Prompt: rmdir /s /q node_modules && del package-lock.json
     • On Windows PowerShell: Remove-Item -Recurse -Force node_modules; Remove-Item package-lock.json
  2. Reinstall all dependencies: npm install (or yarn install)

• Optional: Specify a compatible version
  If you’re using an older version of webpack-dev-server, it might require a specific version of compression. You can install a known-compatible version like this:
  npm install compression@^1.7.4 --save-dev

Once you’ve done this, try starting your application again — it should work without the module not found error!
