json-schema-diff

A work-in-progress tool to diff changes between JSON schemas. A lot of JSON schema features are not implemented and therefore ignored, such as:

• required
• patternProperties (entirely ignored)
• const (changes from {"const": "foo"} to {"type": "string"} are not detected)

Use this tool as a best-effort to find obviously breaking changes in CI, but not for much more.

This crate is used with draft-07 but even that is work in progress.

Usage via CLI

bash cargo run --features=build-binary -- \ schema-old.json \ schema-new.json

Usage as library

```rust use jsonschemadiff::*;

let lhs = serdejson::json! {{ "type": "string", }}; let rhs = serdejson::json! {{ "type": "boolean", }};

asserteq!( jsonschemadiff::diff(lhs, rhs).unwrap(), vec![ Change { path: "".toowned(), change: ChangeKind::TypeRemove { removed: JsonSchemaType::String } }, Change { path: "".to_owned(), change: ChangeKind::TypeAdd { added: JsonSchemaType::Boolean } } ] ); ```
