Real-World Use Cases

JSSON isn’t just for simple configs. It excels at solving real-world production challenges where JSON becomes unwieldy and error-prone.

Why JSSON for Production?

When your JSON files grow beyond a few dozen lines, you start hitting these pain points:

• Massive repetition — Copy-pasting similar structures hundreds of times
• Large datasets — Generating thousands of records manually is impractical
• Multi-environment configs — Maintaining separate files for dev/staging/prod
• Error-prone — Missing commas, mismatched brackets, typos in repeated data
• Hard to maintain — Changes require updating dozens of places

JSSON solves all of these with templates, ranges, map transformations, and conditional logic.

Real-World Examples

Geographic Data

Generate millions of coordinate records for mapping applications, postal code boundaries, or GPS systems.

Problem: Legacy systems need massive JSON files with geographic data
JSSON Solution: Generate 10,000+ records from 20 lines of code

Kubernetes Configuration

Manage multi-environment deployments with consistent naming and environment-specific settings.

Problem: Maintaining separate K8s manifests for prod/staging/dev
JSSON Solution: One template, multiple environments with conditional logic

---

API Gateway Configuration

Configure microservices routing with rate limiting, authentication, and CORS policies.

Problem: Hundreds of similar route definitions with slight variations
JSSON Solution: Templates with service-specific customizations

i18n Translations

Manage translation keys across multiple languages with consistency.

Problem: Keeping translation files in sync across 4+ languages
JSSON Solution: Define keys once, translate across all languages

Feature Flags

Environment-specific feature toggles and configuration management.

Problem: Managing different configs for dev/staging/prod
JSSON Solution: Conditional logic for environment-specific settings

Database Seeding

Generate realistic relational data for development and testing.

Problem: Creating hundreds of related database records manually
JSSON Solution: Templates with foreign key relationships

Common Patterns

All these examples leverage JSSON’s core strengths:

Templates for Structured Data

users [
template { name, role }

"Alice", "admin"
"Bob", "user"
"Carol", "user"
]

Generates an array of objects from tabular data.

Ranges for Sequences

// Generate 1000 IDs
ids = 1..1000

// Generate IP addresses
ips = "192.168.1.1".."192.168.1.255"

Create sequences automatically.

Map Transformations

servers [
template { id, env }

map (s) = {
  id = "srv-" + s.id
  env = s.env
  replicas = s.env == "prod" ? 5 : 2
}

1..10, "prod"
]

Transform and enrich data with logic.

Conditional Logic

config {
logLevel = env == "prod" ? "error" : "debug"
cacheSize = env == "prod" ? "2gb" : "512mb"
}

Environment-specific configurations.

Performance at Scale

JSSON is designed to handle large-scale data generation:

Use Case	JSSON Lines	JSON Output	Ratio
Geographic Data	~70	10,000+ records	140:1
K8s Deployments	~90	21 resources	4:1
API Routes	~85	12 routes	3:1
i18n Keys	~95	27 translations	5:1
Database Seeds	~130	200 records	8:1

Total: ~500 lines of JSSON → ~600+ JSON records

When to Use JSSON

Perfect for:

• Configuration files with repetitive structures
• Large datasets that follow patterns
• Multi-environment setups
• Infrastructure as code
• Data generation for testing

Not ideal for:

• One-off, unique JSON structures
• Extremely dynamic data (use a programming language)
• Simple, small configs (raw JSON is fine)
