Zero Dependencies
The production artifact stays independent of external JSON frameworks.
KISS Java Libraries
KissJson
Tiny zero-dependency Java 17+ JSON serialization and deserialization with direct field mapping, explicit configuration, and useful parse errors.
Maven
<dependency>
<groupId>io.github.arthurhoch</groupId>
<artifactId>kiss-json</artifactId>
<version>0.1.0</version>
</dependency>Small Surface
KissJson maps fields directly without getters, setters, runtime plugins, or transitive dependencies. The API is intended to be easy to remember and easy to inspect.
Quick Example
Json json = Json.create();
String text = json.stringify(user);
User parsed = json.parse(text, User.class);KISS Principles
Explicit Mapping
Field names, null handling, dates, enums, aliases, and required fields are configured directly.
Readable Failures
Parse and mapping errors include path, line, column, and cause context.
