# 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, see [the issue

tracker](https://github.com/getsentry/json-schema-diff/issues).

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

[Install Rust](https://rustup.rs/) and:

```bash

cargo install json-schema-diff

cat schema-old.json schema-new.json

# {"type": "string"}

# {"type": "boolean"}

cargo run --features=build-binary -- \

    schema-old.json \

    schema-new.json

# {"path":"","change":{"TypeRemove":{"removed":"string"}},"is_breaking":true}

# {"path":"","change":{"TypeAdd":{"added":"boolean"}},"is_breaking":false}

```

Sentry uses this tool in

[`sentry-kafka-schemas`](https://github.com/getsentry/sentry-kafka-schemas) to

annotate pull requests with breaking changes made to schema definitions. It

invokes the CLI tool on the schema from master vs the schema in the PR, and

post-processes the output using a Python script for human consumption.

`is_breaking` is just a suggestion. You may choose to ignore it entirely and

instead define which kinds of changes are breaking to you in wrapper scripts.

## Usage as library

```rust

use json_schema_diff::*;

let lhs = serde_json::json! {{ 

    "type": "string",

}};

let rhs = serde_json::json! {{ 

    "type": "boolean",

}};

assert_eq!(

    json_schema_diff::diff(lhs, rhs).unwrap(),

    vec![

        Change {

            path: "".to_owned(),

            change: ChangeKind::TypeRemove { removed: JsonSchemaType::String }

        },

        Change {

            path: "".to_owned(),

            change: ChangeKind::TypeAdd { added: JsonSchemaType::Boolean }

        }

    ]

);

```
