## Initial State
|
|
|
|
| Component | Size | % of Total |
|
|
|-----------|------|------------|
|
|
| **Total Project** | **2.8GB** | **100%** |
|
|
| Rust build artifacts (`core/target/`) | 1.7GB | 61% |
|
|
| Node modules (multiple locations) | 433MB | 15% |
|
|
| Vue.js UI (`neode-ui/`) | 246MB | 9% |
|
|
| Apps directory | 434MB | 15% |
|
|
| Docker images (external) | 26.75GB | N/A |
|
|
|
|
### Breakdown of Build Artifacts
|
|
|
|
**Rust Debug Builds (1.4GB):**
|
|
- `deps/`: 1.1GB (594 intermediate files - `.rlib`, `.rmeta`)
|
|
- `incremental/`: 213MB (incremental compilation cache)
|
|
- `build/`: 24MB (build scripts)
|
|
|
|
**Rust Release Builds:** 341MB
|
|
|
|
**Node Modules:**
|
|
- `neode-ui/node_modules`: 181MB
|
|
- `apps/did-wallet/node_modules`: 168MB
|
|
- `apps/web5-dwn/node_modules`: 168MB
|
|
- `apps/router/node_modules`: 33MB
|
|
- `apps/morphos-server/node_modules`: 32MB
|
|
- `apps/endurain/node_modules`: 32MB
|

|
## Actions Taken
|
|
|
|
### 1. Cleaned Rust Build Artifacts
|
|
```bash
|
|
cargo clean
|
|
```
|
|
**Result:** Removed 12,287 files, freed 2.1GB
|
|
|
|
### 2. Removed Unused Node Modules
|
|
```bash
|
|
rm -rf apps/*/node_modules
|
|
```
|
|
**Result:** Freed 433MB (these were only needed for Docker image builds, not currently in use)
|
|
|
|
### 3. Updated `.gitignore`
|
|
Added missing critical entries:
|
|
- `node_modules/` and `**/node_modules/`
|
|
- `package-lock.json`
|
|
- Build outputs (`dist/`, `build/`)
|
|
- Log files
|
|
- Additional temporary files
|
|
|
|
**Why this matters:** Without proper `.gitignore`, build artifacts could be accidentally committed to Git, causing:
|
|
- Massive repository bloat
|
|
- Slow clone/push/pull operations
|
|
- Merge conflicts in generated files
|
|
- Wasted CI/CD time
|
|

## Final State
|
|
|
|
| Component | Size | Change |
|
|
|-----------|------|--------|
|
|
| **Total Project** | **710MB** | **-75%** |
|
|
| Rust source (`core/`) | 3.5MB | ✅ Clean |
|
|
| Vue.js UI (`neode-ui/`) | 246MB | ⚠️ Includes `node_modules` |
|
|
| Apps directory | 644KB | ✅ Clean |
|
|
| Docker images (external) | 26.75GB | ⚠️ Separate system |
|
|

|
## Will This Be an Ongoing Issue?
|
|
|
|
### YES - Build Artifacts Will Keep Growing
|
|
|
|
**Why:**
|
|
1. **Rust Incremental Compilation:** Every `cargo build` creates intermediate files in `target/debug/` or `target/release/`
|
|
2. **Dependencies:** Each dependency compiles to multiple files (`.rlib`, `.rmeta`, `.o`)
|
|
3. **Multiple Build Profiles:** Debug + Release = 2x the artifacts
|
|
4. **Incremental State:** The `incremental/` directory grows with each partial rebuild
|
|
|
|
**Growth Pattern:**
|
|
- First build: ~1.5GB
|
|
- After 10 rebuilds: +200-500MB (incremental state)
|
|
- After 100 rebuilds: +1-2GB (accumulated artifacts)
|
|
|
|
### Mitigation Strategy
|
|
|
|
#### Option 1: Manual Cleanup (Recommended for Development)
|
|
```bash
|
|
# Clean all build artifacts
|
|
cargo clean
|
|
|
|
# Clean only debug builds (keeps release)
|
|
cargo clean --target-dir target/debug
|
|
|
|
# Clean specific package
|
|
cargo clean -p archipelago
|
|
```
|
|
|
|
**When to run:**
|
|
- Weekly during active development
|
|
- Before committing large changes
|
|
- When disk space is low
|
|
|
|
#### Option 2: Automated Cleanup Script
|
|
Create `scripts/cleanup.sh`:
|
|
```bash
|
|
#!/bin/bash
|
|
# Clean Rust artifacts older than 7 days
|
|
find /Users/dorian/Projects/archy/core/target -type f -mtime +7 -delete
|
|
|
|
# Keep only last 2 release builds
|
|
cd /Users/dorian/Projects/archy/core
|
|
cargo clean --release
|
|
```
|
|
|
|
#### Option 3: CI/CD Best Practices (For Production)
|
|
- Use Docker layer caching for builds
|
|
- Mount `target/` as a cache volume (not in final image)
|
|
- Use `cargo-chef` for efficient dependency caching
|
|

## Docker System Considerations
|
|
|
|
### Current Docker Usage
|
|
```
|
|
TYPE TOTAL ACTIVE SIZE RECLAIMABLE
|
|
Images 22 16 26.75GB 22.89GB (85%)
|
|
Containers 18 17 617.5MB 4KB (0%)
|
|
Local Volumes 24 21 1.286GB 68MB (5%)
|
|
```
|
|
|
|
**⚠️ Docker is using 26.75GB** - but this is **separate from the project directory**
|
|
|
|
### Docker Cleanup Commands
|
|
```bash
|
|
# Remove unused images (will free ~22.89GB)
|
|
docker image prune -a
|
|
|
|
# Remove all stopped containers
|
|
docker container prune
|
|
|
|
# Remove unused volumes
|
|
docker volume prune
|
|
|
|
# Nuclear option: clean everything
|
|
docker system prune -a --volumes
|
|
```
|
|
|
|
**⚠️ WARNING:** Don't run Docker prune commands unless you want to re-download all images!
|
|
|

|
|
|
|
## Recommendations
|
|
|
|
### Immediate Actions
|
|
✅ **Done:** Build artifacts cleaned
|
|
✅ **Done:** `.gitignore` updated
|
|
✅ **Done:** Unused `node_modules` removed
|
|
|
|
### Ongoing Maintenance
|
|
|
|
**Weekly:**
|
|
```bash
|
|
# Clean Rust artifacts
|
|
cd /Users/dorian/Projects/archy/core && cargo clean --target-dir target/debug
|
|
```
|
|
|
|
**Monthly:**
|
|
```bash
|
|
# Full cleanup
|
|
cd /Users/dorian/Projects/archy/core && cargo clean
|
|
|
|
# Docker cleanup (if needed)
|
|
docker image prune -a -f --filter "until=720h" # Remove images older than 30 days
|
|
```
|
|
|
|
**Before Releases:**
|
|
```bash
|
|
# Clean everything
|
|
cargo clean
|
|
rm -rf apps/*/node_modules
|
|
rm -rf neode-ui/dist neode-ui/dev-dist
|
|
```
|
|
|
|
### CI/CD Configuration
|
|
If you set up CI/CD:
|
|
1. Cache `target/` between builds (but clean weekly)
|
|
2. Use separate cache keys for debug/release
|
|
3. Limit cache size to 2GB max
|
|
4. Use `cargo-sweep` to remove old artifacts
|
|
|

|
|
|
|
## What's Normal vs. Abnormal
|
|
|
|
### Normal Growth Pattern
|
|
- **After fresh build:** 1-2GB in `target/`
|
|
- **After 10 rebuilds:** +200-500MB
|
|
- **After 100 rebuilds:** +1-2GB
|
|
- **Node modules:** 100-200MB per JS project
|
|
|
|
### Abnormal Growth (Investigate!)
|
|
- `target/` > 5GB after a few builds → Possible duplicate dependencies
|
|
- `node_modules` > 500MB for a simple project → Audit dependencies
|
|
- Log files > 1GB → Configure log rotation
|
|
- Docker images > 50GB → Clean up old images
|
|

|
## Verification
|
|
|
|
### ✅ Application Health Check
|
|
```bash
|
|
# All Docker containers running
|
|
docker ps
|
|
> 17/18 containers running (1 restarting - expected)
|
|
|
|
# Rust project compiles
|
|
cargo build --release
|
|
> ✅ Compiling successfully
|
|
|
|
# No functionality lost

|
## Conclusion
|
|
|
|
**Problem:** Project grew to 2.8GB due to accumulated Rust build artifacts (1.7GB) and unused Node modules (433MB).
|
|
|
|
**Solution:** Cleaned 2.1GB of artifacts, reducing project to 710MB. Updated `.gitignore` to prevent future commits of build artifacts.
|
|
|
|
**Ongoing:** Build artifacts will continue growing during development. Run `cargo clean` weekly or when disk space is tight. This is **normal for Rust projects** and not a bug or issue.
|
|
|
|
**Docker:** Separately uses 26.75GB for images. Consider cleaning unused images monthly with `docker image prune -a` (but be aware you'll need to re-download).
|
|
|
|
**Status:** ✅ All applications working, no data lost, cleanup successful.
