Format YAML

Transform messy or inconsistent YAML into clean, properly indented format following YAML best practices. Essential for maintaining readable configuration files and ensuring proper parsing.

Example:

Unformatted YAML:

name: my-app
version:1.0.0
services:
web:
image: nginx:latest
ports:
- "80:80"
environment:
NODE_ENV: production
DATABASE_URL: postgres://user:pass@db:5432/myapp

Formatted YAML:

name: my-app
version: 1.0.0
services:
  web:
    image: nginx:latest
    ports:
      - "80:80"
    environment:
      NODE_ENV: production
      DATABASE_URL: postgres://user:pass@db:5432/myapp

Formatting Features:

  • Consistent 2-space indentation
  • Proper key-value alignment
  • Array and object structuring
  • Comment preservation and alignment
  • Trailing space removal

Use Cases:

  • Docker Compose file cleanup
  • Kubernetes manifests formatting
  • CI/CD pipeline configuration
  • Application config files
  • GitHub Actions workflows

Minify YAML

Remove comments, extra whitespace, and unnecessary formatting from YAML files to reduce size while maintaining functionality. Useful for production deployments and automated processing.

Example:

Full YAML with Comments:

# Application configuration
app:
  name: my-application  # Application name
  version: 1.2.3       # Current version
  
# Database settings
database:
  host: localhost      # Database host
  port: 5432          # Database port
  name: myapp_prod    # Database name
  
# Feature flags
features:
  - analytics         # Enable analytics
  - notifications     # Enable push notifications

Minified YAML:

app:
  name: my-application
  version: 1.2.3
database:
  host: localhost
  port: 5432
  name: myapp_prod
features:
  - analytics
  - notifications

What Gets Removed:

  • All comments (# and inline)
  • Extra blank lines
  • Trailing whitespace
  • Excessive spacing
  • Development annotations

Benefits:

  • Smaller file size (10-30% reduction)
  • Faster parsing and processing
  • Cleaner production deployments
  • Reduced network transfer time
  • Automated CI/CD optimization

YAML ↔ JSON Conversion

Convert between YAML and JSON formats seamlessly. Essential for working with different APIs, configuration systems, and data processing pipelines that require specific formats.

YAML to JSON

YAML Input:

user:
  name: John Doe
  age: 30
  skills:
    - JavaScript
    - Python
  active: true

JSON Output:

{
  "user": {
    "name": "John Doe",
    "age": 30,
    "skills": [
      "JavaScript",
      "Python"
    ],
    "active": true
  }
}

JSON to YAML

JSON Input:

{
  "api": {
    "version": "v1",
    "endpoints": [
      "/users",
      "/posts"
    ],
    "auth": true
  }
}

YAML Output:

api:
  version: v1
  endpoints:
    - /users
    - /posts
  auth: true

Conversion Use Cases:

YAML to JSON:
  • API payload conversion
  • Database storage format
  • JavaScript/web application data
  • REST API responses
JSON to YAML:
  • Configuration file creation
  • Docker Compose setup
  • CI/CD pipeline definitions
  • Human-readable documentation

YAML Best Practices & Guidelines

✅ Do

  • Use consistent 2-space indentation
  • Quote strings with special characters
  • Use meaningful key names
  • Validate YAML syntax before deployment
  • Use comments for complex configurations
  • Keep line length under 80 characters

❌ Don't

  • Mix tabs and spaces for indentation
  • Use tabs (use spaces only)
  • Leave trailing whitespace
  • Use inconsistent quoting styles
  • Create deeply nested structures unnecessarily
  • Include sensitive data without encryption

YAML Syntax Reminders

Indentation: 2 spaces (no tabs)

Lists: Use "- " for array items

Strings: Quote when containing special chars

Booleans: true/false (lowercase)

Multi-line: Use | for literal, > for folded

Comments: Use # for line comments

Null values: Use null or ~ or empty

Numbers: 123, 45.67, 1.2e3

Common YAML Patterns

Docker Compose

version: '3.8'
services:
  web:
    image: nginx:latest
    ports:
      - "80:80"
    environment:
      - NODE_ENV=production

GitHub Actions

name: CI
on:
  push:
    branches: [main]
jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - run: npm test

Kubernetes

apiVersion: apps/v1
kind: Deployment
metadata:
  name: my-app
spec:
  replicas: 3
  selector:
    matchLabels:
      app: my-app

Configuration

app:
  name: MyApp
  debug: false
database:
  url: ${DATABASE_URL}
  pool_size: 10
features:
  - authentication
  - logging
