## When to Use This Skill
- Setting up Bazel for monorepos
- Configuring remote caching/execution
- Optimizing build times
- Writing custom Bazel rules
- Debugging build issues
- Migrating to Bazel
## Core Concepts
### 1. Bazel Architecture

### 2. Key Concepts
| Concept | Description |
|---------|-------------|
| **Target** | Buildable unit (library, binary, test) |
| **Package** | Directory with BUILD file |
| **Label** | Target identifier `//path/to:target` |
| **Rule** | Defines how to build a target |
| **Aspect** | Cross-cutting build behavior |
## Templates

### Template 3: TypeScript Library BUILD
```python
# libs/utils/BUILD.bazel
load("@aspect_rules_ts//ts:defs.bzl", "ts_project")
load("@aspect_rules_js//js:defs.bzl", "js_library")
load("@npm//:defs.bzl", "npm_link_all_packages")
npm_link_all_packages(name = "node_modules")
ts_project(

srcs = glob(["src/**/*.ts"]),
declaration = True,
source_map = True,
tsconfig = "//:tsconfig.json",
deps = [
":node_modules/@types/node",
],
)
js_library(
name = "utils",
srcs = [":utils_ts"],
visibility = ["//visibility:public"],
)
# Tests
load("@aspect_rules_jest//jest:defs.bzl", "jest_test")
jest_test(
name = "utils_test",
config = "//:jest.config.js",
data = [
":utils",
"//:node_modules/jest",
],
node_modules = "//:node_modules",
)
```
### Template 4: Python Library BUILD
```python
# libs/ml/BUILD.bazel
load("@rules_python//python:defs.bzl", "py_library", "py_test", "py_binary")
load("@pip//:requirements.bzl", "requirement")
py_library(
name = "ml",
srcs = glob(["src/**/*.py"]),
deps = [
requirement("numpy"),
requirement("pandas"),
requirement("scikit-learn"),
"//libs/utils:utils_py",
],
visibility = ["//visibility:public"],
)
py_test(
name = "ml_test",
srcs = glob(["tests/**/*.py"]),
deps = [
":ml",
requirement("pytest"),
],
size = "medium",
timeout = "moderate",
)
py_binary(
name = "train",
srcs = ["train.py"],
deps = [":ml"],
data = ["//data:training_data"],
)
```
### Template 5: Custom Rule for Docker
```python
# tools/bazel/rules/docker.bzl
def _docker_image_impl(ctx):
dockerfile = ctx.file.dockerfile
base_image = ctx.attr.base_image
layers = ctx.files.layers
# Build the image
output = ctx.actions.declare_file(ctx.attr.name + ".tar")
args = ctx.actions.args()
args.add("--dockerfile", dockerfile)
args.add("--output", output)
args.add("--base", base_image)
args.add_all("--layer", layers)
ctx.actions.run(
inputs = [dockerfile] + layers,
outputs = [output],
executable = ctx.executable._builder,
arguments = [args],
mnemonic = "DockerBuild",
progress_message = "Building Docker image %s" % ctx.label,
)
return [DefaultInfo(files = depset([output]))]
docker_image = rule(
implementation = _docker_image_impl,
attrs = {
"dockerfile": attr.label(
allow_single_file = [".dockerfile", "Dockerfile"],
mandatory = True,
),
"base_image": attr.string(mandatory = True),
"layers": attr.label_list(allow_files = True),
"_builder": attr.label(
default = "//tools/docker:builder",
executable = True,
cfg = "exec",
),
},
)
```
### Template 6: Query and Dependency Analysis
```bash
# Find all dependencies of a target
bazel query "deps(//apps/web:web)"
# Find reverse dependencies (what depends on this)
bazel query "rdeps(//..., //libs/utils:utils)"
# Find all targets in a package
bazel query "//libs/..."
# Find changed targets since commit
bazel query "rdeps(//..., set($(git diff --name-only HEAD~1 | sed 's/.*/"&"/' | tr '\n' ' ')))"
# Generate dependency graph
bazel query "deps(//apps/web:web)" --output=graph | dot -Tpng > deps.png
# Find all test targets
bazel query "kind('.*_test', //...)"
# Find targets with specific tag
bazel query "attr(tags, 'integration', //...)"
# Compute build graph size
bazel query "deps(//...)" --output=package | wc -l
```
### Template 7: Remote Execution Setup
```python
# platforms/BUILD.bazel
platform(
name = "linux_x86_64",
constraint_values = [
"@platforms//os:linux",
"@platforms//cpu:x86_64",
],
exec_properties = {
"container-image": "docker://gcr.io/myproject/bazel-worker:latest",
"OSFamily": "Linux",
},
)
platform(
name = "remote_linux",
parents = [":linux_x86_64"],
exec_properties = {
"Pool": "default",
"dockerNetwork": "standard",
},
)
# toolchains/BUILD.bazel
toolchain(
name = "cc_toolchain_linux",
exec_compatible_with = [
"@platforms//os:linux",
"@platforms//cpu:x86_64",
],
target_compatible_with = [
"@platforms//os:linux",
"@platforms//cpu:x86_64",
],
toolchain = "@remotejdk11_linux//:jdk",
toolchain_type = "@bazel_tools//tools/jdk:runtime_toolchain_type",
)
```
## Performance Optimization
```bash
# Profile build
bazel build //... --profile=profile.json
bazel analyze-profile profile.json
# Identify slow actions
bazel build //... --execution_log_json_file=exec_log.json
# Memory profiling
bazel build //... --memory_profile=memory.json
# Skip analysis cache
bazel build //... --notrack_incremental_state
```
## Best Practices
### Do's
- **Use fine-grained targets** - Better caching
- **Pin dependencies** - Reproducible builds
- **Enable remote caching** - Share build artifacts
- **Use visibility wisely** - Enforce architecture
- **Write BUILD files per directory** - Standard convention
### Don'ts
- **Don't use glob for deps** - Explicit is better
- **Don't commit bazel-* dirs** - Add to .gitignore
- **Don't skip WORKSPACE setup** - Foundation of build
- **Don't ignore build warnings** - Technical debt

directory?: string;
}
export default async function featureLibraryGenerator(
tree: Tree,
options: FeatureLibraryGeneratorSchema
) {
const { name, scope, directory } = options;
const projectDirectory = directory
? `${directory}/${name}`
: `libs/${scope}/feature-${name}`;
// Generate base library
await libraryGenerator(tree, {
name: `feature-${name}`,
directory: projectDirectory,
tags: `type:feature,scope:${scope}`,
style: 'css',
skipTsConfig: false,
skipFormat: true,
unitTestRunner: 'jest',
linter: 'eslint',
});
// Add custom files
const projectConfig = readProjectConfiguration(tree, `${scope}-feature-${name}`);
const projectNames = names(name);
generateFiles(
tree,
joinPathFragments(__dirname, 'files'),
projectConfig.sourceRoot,
{
...projectNames,
scope,
tmpl: '',
}
);
await formatFiles(tree);
}
```
### Template 5: CI Configuration with Affected
```yaml
# .github/workflows/ci.yml
name: CI
on:
push:
branches: [main]
pull_request:
branches: [main]
env:
NX_CLOUD_ACCESS_TOKEN: ${{ secrets.NX_CLOUD_ACCESS_TOKEN }}
jobs:
main:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
with:
fetch-depth: 0
- uses: actions/setup-node@v4
with:
node-version: 20
cache: 'npm'
- name: Install dependencies
run: npm ci
- name: Derive SHAs for affected commands
uses: nrwl/nx-set-shas@v4
- name: Run affected lint
run: npx nx affected -t lint --parallel=3
- name: Run affected test
run: npx nx affected -t test --parallel=3 --configuration=ci
- name: Run affected build
run: npx nx affected -t build --parallel=3
- name: Run affected e2e
run: npx nx affected -t e2e --parallel=1
```
### Template 6: Remote Caching Setup
```typescript
// nx.json with Nx Cloud
{
"tasksRunnerOptions": {
"default": {
"runner": "nx-cloud",
"options": {
"cacheableOperations": ["build", "lint", "test", "e2e"],
"accessToken": "your-nx-cloud-token",
"parallel": 3,
"cacheDirectory": ".nx/cache"
}
}
},
"nxCloudAccessToken": "your-nx-cloud-token"
}
// Self-hosted cache with S3
{
"tasksRunnerOptions": {
"default": {
"runner": "@nx-aws-cache/nx-aws-cache",
"options": {
"cacheableOperations": ["build", "lint", "test"],
"awsRegion": "us-east-1",
"awsBucket": "my-nx-cache-bucket",
"awsProfile": "default"
}
}
}
}
```
## Common Commands
```bash
# Generate new library
nx g @nx/react:lib feature-auth --directory=libs/web --tags=type:feature,scope:web
# Run affected tests
nx affected -t test --base=main
# View dependency graph
nx graph
# Run specific project
nx build web --configuration=production
# Reset cache
nx reset
# Run migrations
nx migrate latest
nx migrate --run-migrations
```
## Best Practices
### Do's
- **Use tags consistently** - Enforce with module boundaries
- **Enable caching early** - Significant CI savings
- **Keep libs focused** - Single responsibility
- **Use generators** - Ensure consistency
- **Document boundaries** - Help new developers
### Don'ts
- **Don't create circular deps** - Graph should be acyclic
- **Don't skip affected** - Test only what changed
- **Don't ignore boundaries** - Tech debt accumulates
- **Don't over-granularize** - Balance lib count

"globalDependencies": [
".env",
".env.local"
],
"globalEnv": [
"NODE_ENV",
"VERCEL_URL"

]
},
"test": {
"outputs": ["coverage/**"],
"inputs": [

}
}
}
```
### Template 3: Remote Caching with Vercel
```bash
# Login to Vercel
npx turbo login
# Link to Vercel project
npx turbo link
# Run with remote cache
turbo build --remote-only
# CI environment variables
TURBO_TOKEN=your-token
TURBO_TEAM=your-team
```
```yaml
# .github/workflows/ci.yml
name: CI
on:
push:
branches: [main]
pull_request:
env:
TURBO_TOKEN: ${{ secrets.TURBO_TOKEN }}
TURBO_TEAM: ${{ vars.TURBO_TEAM }}

```
### Template 4: Self-Hosted Remote Cache
```typescript
// Custom remote cache server (Express)
import express from 'express';
import { createReadStream, createWriteStream } from 'fs';
import { mkdir } from 'fs/promises';
import { join } from 'path';
const app = express();
const CACHE_DIR = './cache';
// Get artifact
app.get('/v8/artifacts/:hash', async (req, res) => {
const { hash } = req.params;
const team = req.query.teamId || 'default';
const filePath = join(CACHE_DIR, team, hash);
try {
const stream = createReadStream(filePath);
stream.pipe(res);
} catch {
res.status(404).send('Not found');
}
});
// Put artifact
app.put('/v8/artifacts/:hash', async (req, res) => {
const { hash } = req.params;
const team = req.query.teamId || 'default';
const dir = join(CACHE_DIR, team);
const filePath = join(dir, hash);
await mkdir(dir, { recursive: true });
const stream = createWriteStream(filePath);
req.pipe(stream);
stream.on('finish', () => {
res.json({ urls: [`${req.protocol}://${req.get('host')}/v8/artifacts/${hash}`] });
});
});
// Check artifact exists
app.head('/v8/artifacts/:hash', async (req, res) => {
const { hash } = req.params;

```json
// turbo.json for self-hosted cache
{
"remoteCache": {
"signature": false
}
}
```
```bash
# Use self-hosted cache
turbo build --api="http://localhost:3000" --token="my-token" --team="my-team"
```
### Template 5: Filtering and Scoping
```bash
# Build specific package
turbo build --filter=@myorg/web
# Build package and its dependencies
turbo build --filter=@myorg/web...
# Build package and its dependents
turbo build --filter=...@myorg/ui
# Build changed packages since main
turbo build --filter='...[origin/main]'
# Build packages in directory
turbo build --filter='./apps/*'
# Combine filters
turbo build --filter=@myorg/web --filter=@myorg/docs
# Exclude package
turbo build --filter='!@myorg/docs'
# Include dependencies of changed
turbo build --filter='...[HEAD^1]...'
```
### Template 6: Advanced Pipeline Configuration
```json
{
"$schema": "https://turbo.build/schema.json",
"pipeline": {
"build": {
"dependsOn": ["^build"],
"outputs": ["dist/**"],
"inputs": [
"$TURBO_DEFAULT$",
"!**/*.md",
"!**/*.test.*"
]
},
"test": {
"dependsOn": ["^build"],
"outputs": ["coverage/**"],
"inputs": [
"src/**",
"tests/**",
"*.config.*"
],
"env": ["CI", "NODE_ENV"]
},
"test:e2e": {
"dependsOn": ["build"],
"outputs": [],
"cache": false
},
"deploy": {
"dependsOn": ["build", "test", "lint"],
"outputs": [],
"cache": false
},
"db:generate": {
"cache": false
},
"db:push": {
"cache": false,
"dependsOn": ["db:generate"]
},
"@myorg/web#build": {
"dependsOn": ["^build", "@myorg/db#db:generate"],
"outputs": [".next/**"],
"env": ["NEXT_PUBLIC_*"]
}
}
}
```
### Template 7: Root package.json Setup
```json
{
"name": "my-turborepo",
"private": true,
"workspaces": [
"apps/*",
"packages/*"
],
"scripts": {
"build": "turbo build",
"dev": "turbo dev",
"lint": "turbo lint",
"test": "turbo test",
"clean": "turbo clean && rm -rf node_modules",
"format": "prettier --write \"**/*.{ts,tsx,md}\"",
"changeset": "changeset",
"version-packages": "changeset version",
"release": "turbo build --filter=./packages/* && changeset publish"
},
"devDependencies": {
"turbo": "^1.10.0",
"prettier": "^3.0.0",
"@changesets/cli": "^2.26.0"
},
"packageManager": "npm@10.0.0"
}
```
## Debugging Cache
```bash
# Dry run to see what would run
turbo build --dry-run
# Verbose output with hashes
turbo build --verbosity=2
# Show task graph
turbo build --graph
# Force no cache
turbo build --force
# Show cache status
turbo build --summarize
# Debug specific task
TURBO_LOG_VERBOSITY=debug turbo build --filter=@myorg/web
```
## Best Practices
### Do's
- **Define explicit inputs** - Avoid cache invalidation
- **Use workspace protocol** - `"@myorg/ui": "workspace:*"`
- **Enable remote caching** - Share across CI and local
- **Filter in CI** - Build only affected packages
- **Cache build outputs** - Not source files
### Don'ts
- **Don't cache dev servers** - Use `persistent: true`
- **Don't include secrets in env** - Use runtime env vars
- **Don't ignore dependsOn** - Causes race conditions
- **Don't over-filter** - May miss dependencies
