JSON Language Prompt Snippet

Key Concepts

• Strict Syntax: No trailing commas, no comments (unlike JSONC or JSON5), double-quoted strings only
• Data Types: Objects, arrays, strings, numbers, booleans, and null — no undefined or date types
• Nested Structure: Arbitrary nesting depth for hierarchical configuration or data
• Schema Validation: JSON Schema ($schema keyword) for validating structure and types
• JSONC: JSON with Comments variant used by VS Code, tsconfig.json, and other tooling
• JSON5: Extended JSON allowing comments, trailing commas, unquoted keys, and more
• JSON Lines (.jsonl): One JSON object per line for streaming data processing

Notable File Patterns

• package.json — Node.js project manifest with dependencies, scripts, and metadata
• tsconfig.json — TypeScript compiler configuration (actually JSONC)
• .eslintrc.json — ESLint linting rules and configuration
• *.schema.json — JSON Schema definitions for validation
• composer.json — PHP Composer project manifest
• appsettings.json — .NET application configuration
• manifest.json — Browser extension or PWA manifest

Edge Patterns

• package.json configures the build toolchain and defines project dependencies
• tsconfig.json configures TypeScript compilation for all .ts files
• JSON Schema files defines_schema for API request/response validation
• Config JSON files configures the runtime behavior of the application

Summary Style

"Node.js project manifest defining N dependencies, build scripts, and project metadata." "TypeScript compiler configuration enabling strict mode with path aliases for monorepo packages." "JSON Schema defining the request/response structure for the user API endpoint."
