# Production Build Optimization Scripts
|
|
|
|
## optimize-standalone.js
|
|
|
|
This script removes unnecessary development dependencies from the Next.js standalone build output to reduce the production Docker image size.
|
|
|
|
### What it does
|
|
|
|
The script specifically targets and removes `jest-worker` packages that are bundled with Next.js but not needed in production. These packages are included because:
|
|
|
|
1. Next.js includes jest-worker in its compiled dependencies
|
|
1. terser-webpack-plugin (used by Next.js for minification) depends on jest-worker
|
|
1. pnpm's dependency resolution creates symlinks to jest-worker in various locations
|
|
|
|
### Usage
|
|
|
|
The script is automatically run during Docker builds via the `build:docker` npm script:
|
|
|
|
```bash
|
|
# Docker build (removes jest-worker after build)
|
|
pnpm build:docker
|
|
```
|
|
|
|
To run the optimization manually:
|
|
|
|
```bash
|
|
node scripts/optimize-standalone.js
|
|
```
|
|
|
|
### What gets removed
|
|
|
|
- `node_modules/.pnpm/next@*/node_modules/next/dist/compiled/jest-worker`
|
|
- `node_modules/.pnpm/terser-webpack-plugin@*/node_modules/jest-worker` (symlinks)
|
|
- `node_modules/.pnpm/jest-worker@*` (actual packages)
|
|
|
|
### Impact
|
|
|
|
Removing jest-worker saves approximately 36KB per instance from the production image. While this may seem small, it helps ensure production images only contain necessary runtime dependencies.
