# openapi-json-schema

Minimalistic OpenAPI 3 ⬌ JSON Schema (draft 7) conversion.

* This package aims at full conversion support except reference resolution, but isn't there yet. Currently supports:
* `null`/`nullable` conversion
* `$ref`'s being converted `#/definitions` <-> `#/components/schemas`
* `const` ➡ `enum` when converting to OpenAPI
* `$id`/`$comment` ➡ `info['x-id']`/`info['x-comment']` when converting to OpenAPI
* *PR's are welcome.*
* JSON `$ref`s are not resolved.
* This package has no dependencies, and will continue to have no dependencies - re: minimalistic.

## Versions

* Since v2 this is a [pure ESM][pure-esm] package, and requires Node.js >=14.13.1. It cannot be used from CommonJS.

# Usage

```ts
import {
jsonSchemaToOpenApiSchema,
openApiSchemaToJsonSchema,
} from 'openapi-json-schema'

// JSON Schema to Open API
const openApi = jsonSchemaToOpenApiSchema( jsonSchema );

// Open API to JSON Schema
const jsonSchema = openApiSchemaToJsonSchema( openApi );
```

## Utilities

The library exports utilities; `encodeRefNameJsonSchema`, `decodeRefNameJsonSchema`, `encodeRefNameOpenApi` and `decodeRefNameOpenApi` used to convert to/from references names, and their corresponding encoding in JSON Schema and Open API.
