Ionic 3 Build Stuck on Webpack Step After Copy (CLI Freezes)

Hey there, sorry to hear your Ionic 3 build's getting stuck on the webpack step right after copy—this is super frustrating, but let's walk through some tried-and-true fixes to get you back on track:

Wipe All Build Caches & Dependencies
Old cached files or corrupted dependencies are often the culprit here. Run these commands to start fresh:
```
rm -rf node_modules
rm package-lock.json
npm cache clean --force
npm install
```
Don't forget to clear Ionic's native build cache too:
```
ionic cordova clean android
```
Check for Troublesome Plugins
If you added any new Cordova or npm plugins since your last successful build, they might be causing webpack to hang. Try removing recent plugins one by one and re-running the build to spot the problem child. Plugins that handle assets or have complex pre-build scripts are usually the suspects.
Bump Node.js Memory Limits
Webpack can hit memory caps during production builds, especially for larger apps. Try running the build with increased memory allocation:
```
node --max-old-space-size=4096 ./node_modules/@ionic/app-scripts/bin/ionic-app-scripts.js build --prod
```
Then follow up with the Cordova build:
```
ionic cordova build android
```
Update Ionic App Scripts
Your project is using ionic-app-scripts 3.1.9, which is a bit outdated. Ionic 3's final stable app-scripts version is 3.2.4—update it with:
```
npm install @ionic/app-scripts@3.2.4 --save-dev
```
This often resolves build pipeline bugs from older versions.
Inspect Custom Webpack Configs
If you modified your webpack config (either via a standalone webpack.config.js or ionic.config.json), double-check for misconfigured loaders, infinite loops, or broken plugin setups. Try reverting to the default config temporarily to see if the build unfreezes.
Run Build in Verbose Mode
To pinpoint exactly where webpack is stuck, enable verbose logging:
```
npm run ionic:build --prod -- --verbose
```
This will print detailed logs of each module webpack is processing, making it easy to spot the problematic file or dependency.
