JSON (JavaScript Object Notation)

JSON ist ein leichtgewichtiges Datenaustauschformat, das für Menschen leicht lesbar und für Maschinen einfach zu parsen ist. Es ist der Standard für Web-APIs und Konfigurationsdateien.

MIME-Typ

application/json

Typ

Text

Komprimierung

Verlustfrei

Vorteile

+ Human-readable and writable with minimal syntax
+ Native parsing in every programming language
+ Dominant format for REST APIs and web services
+ Lightweight — less verbose than XML

Nachteile

− No comment syntax — cannot annotate configuration files
− No native date, binary, or schema types
− Trailing commas cause parse errors in strict parsers

Wann Sie .JSON verwenden sollten

Verwenden Sie JSON für Web-APIs, Konfigurationsdateien, Datenspeicherung und jede strukturierte Datenkommunikation zwischen Systemen.

Technische Details

JSON unterstützt sechs Datentypen: String, Number, Boolean, null, Object und Array. Es ist ein Teilmenge der JavaScript-Notation, aber sprachunabhängig. UTF-8 ist die Standardkodierung.

Geschichte

Douglas Crockford spezifizierte JSON Anfang der 2000er Jahre als leichtgewichtige Alternative zu XML. Es wurde 2013 als ECMA-404 und 2017 als RFC 8259 standardisiert.
