JSONpõhiste

JSONpõhiste refers to data formats and APIs that use JavaScript Object Notation (JSON) as the primary means of encoding information. In practice, JSON-based systems handle structured data as nested objects and arrays, with strings, numbers, booleans, and null values.

JSON is lightweight and human-readable, and is widely used in web services, mobile applications, and configuration files. It is language-agnostic and maps naturally to data structures in most programming languages. Many APIs employ RESTful or GraphQL designs that return JSON payloads.

Validation and schemas: While JSON itself is schema-less, JSON Schema and other contract mechanisms allow validation of data structure and types, enabling versioning and compatibility checks.

Streaming and variants: For large or continuous data, newline-delimited JSON (NDJSON) or JSON streaming supports incremental parsing. JSON:API provides a standard for structuring responses. Binary data can be embedded as base64 or transferred separately using multipart formats.

Security and performance: JSON parsing is usually fast, but overly large payloads can impact performance. Ensure input validation to prevent injection, and avoid eval-based parsing. Use appropriate content types and implement proper access control.

Comparison and limits: JSON is human-readable but lacks comments; XML offers richer metadata in some contexts. JSON's typeless nature requires careful handling of numbers and date formats. On the other hand, XML and YAML provide comments and richer schemas; JSON aligns well with modern web and microservices.
