RESL

RESL = Runtime Evaluated Serialization Language

RESL is a modern configuration and serialization language with variables, expressions, and dynamic runtime evaluation designed to solve the limitations of traditional static configuration formats like JSON.

PRONUNCIATION

RESL is pronounced like "wrestle"

Core Purpose

RESL is designed to bring programming capabilities to config files, eliminating the common problems of repetitive, verbose, and hard-to-maintain configuration files.

Key Features

Dynamic Configuration: Variables, functions, and computed values
Familiar Syntax: Combines the best of JSON, JavaScript, and functional programming
Flexible Structure: Any expression can be top-level
Rich Data Types: Strings, numbers, booleans, lists, and maps
Powerful Operations: Binary operations, conditionals, transformations, and more

Use Cases

RESL is ideal for:

Application Configuration: Server settings, database connections, feature flags
Infrastructure as Code: Kubernetes manifests, Docker configurations, CI/CD pipelines
Dynamic Configurations: Environment-specific settings, computed values, conditional logic
Data Generation: Test data, mock configurations, templated content
API Responses: Dynamic JSON generation with computed fields
