📚 JSON to YAML Guide

JSON vs YAML

Both JSON and YAML are data serialization formats, but they have different strengths:

Example Conversion

JSON:

{
  "apiVersion": "apps/v1",
  "kind": "Deployment",
  "metadata": {
    "name": "nginx-deployment",
    "labels": {
      "app": "nginx"
    }
  }
}

YAML:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-deployment
  labels:
    app: nginx

Common Use Cases

• Kubernetes manifests - K8s uses YAML for resource definitions
• Docker Compose - docker-compose.yml configuration
• CI/CD pipelines - GitHub Actions, GitLab CI, CircleCI
• Ansible playbooks - Infrastructure as code
• Configuration files - Application settings

Code Examples

// JavaScript (using js-yaml library)
const yaml = require('js-yaml');
const jsonData = { name: 'example', version: '1.0' };
const yamlString = yaml.dump(jsonData);

# Python
import yaml
import json

json_data = {"name": "example", "version": "1.0"}
yaml_string = yaml.dump(json_data, default_flow_style=False)
