**Purpose**: Guide for optimizing build and test workflows
|
|
**Status**: Complete

|
|
|
## Overview
|
|
|
|
This guide provides strategies and best practices for optimizing build and test workflows across the integrated workspace.
|
|
|

|
|
|
|
## Optimization Strategies
|
|
|
|
### 1. Build Caching
|
|
|
|
#### Turborepo Caching
|
|
|
|
**Configuration**: `turbo.json`
|
|
|
|
```json
|
|
{
|
|
"pipeline": {
|
|
"build": {
|
|
"dependsOn": ["^build"],
|
|
"outputs": ["dist/**", ".next/**", "build/**"],
|
|
"cache": true
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
**Benefits**:
|
|
- Faster builds (skip unchanged packages)
|
|
- Reduced CI/CD time
|
|
- Lower resource usage
|
|
|
|
#### Docker Layer Caching
|
|
|
|
```dockerfile
|
|
# Cache dependencies
|
|
COPY package.json pnpm-lock.yaml ./
|
|
RUN pnpm install --frozen-lockfile
|
|
|
|
# Copy source (changes more frequently)
|
|
COPY src ./src
|
|
RUN pnpm build
|
|
```
|
|
|
|
### 2. Parallel Execution
|
|
|
|
#### Turborepo Parallel Tasks
|
|
|
|
```json
|
|
{
|
|
"pipeline": {
|
|
"build": {
|
|
"dependsOn": ["^build"]
|
|
},
|
|
"test": {
|
|
"dependsOn": ["build"]
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
**Benefits**:
|
|
- Build packages in parallel
|
|
- Run tests concurrently
|
|
- Faster overall execution
|
|
|
|
### 3. Incremental Builds
|
|
|
|
#### TypeScript Incremental Compilation
|
|
|
|
```json
|
|
{
|
|
"compilerOptions": {
|
|
"incremental": true,
|
|
"tsBuildInfoFile": ".tsbuildinfo"
|
|
}
|
|
}
|
|
```
|
|
|
|
**Benefits**:
|
|
- Only rebuild changed files
|
|
- Faster compilation
|
|
- Better IDE performance
|
|
|
|
### 4. Test Optimization
|
|
|
|
#### Test Filtering
|
|
|
|
```bash
|
|
# Run only changed tests
|
|
pnpm test --changed
|
|
|
|
# Run tests in parallel
|
|
pnpm test --parallel
|
|
|
|
# Use test cache
|
|
pnpm test --cache
|
|
```
|
|
|
|
#### Test Sharding
|
|
|
|
```bash
|
|
# Split tests across workers
|
|
pnpm test --shard=1/4
|
|
pnpm test --shard=2/4
|
|
pnpm test --shard=3/4
|
|
pnpm test --shard=4/4
|
|
```
|
|
|

|
|
|
|
## CI/CD Optimization
|
|
|
|
### 1. Conditional Execution
|
|
|
|
```yaml
|
|
# Only run if relevant files changed
|
|
jobs:
|
|
test:
|
|
if: contains(github.event.head_commit.modified, 'src/')
|
|
```
|
|
|
|
### 2. Matrix Strategy
|
|
|
|
```yaml
|
|
strategy:
|
|
matrix:
|
|
node-version: [18, 20]
|
|
os: [ubuntu-latest, windows-latest]
|
|
```
|
|
|
|
### 3. Artifact Caching
|
|
|
|
```yaml
|
|
- uses: actions/cache@v3
|
|
with:
|
|
path: |
|
|
node_modules
|
|
.next/cache
|
|
key: ${{ runner.os }}-${{ hashFiles('**/pnpm-lock.yaml') }}
|
|
```
|
|
|

|
## Monitoring & Metrics
|
|
|
|
### Build Metrics
|
|
|
|
Track:
|
|
- Build duration
|
|
- Cache hit rate
|
|
- Test execution time
|
|
- Resource usage
|
|
|
|
### Optimization Targets
|
|
|
|
- **Build time**: < 5 minutes (incremental)
|
|
- **Test time**: < 10 minutes (full suite)
|
|
- **Cache hit rate**: > 80%
|
|
- **Parallel efficiency**: > 70%
|
|
