This package currently converts from [OpenAPI 3.0](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.0.0.md) to [JSON Schema Draft 4](http://json-schema.org/specification-links.html#draft-4). Features -------- [](#features) - converts OpenAPI 3.0 Schema Object to JSON Schema Draft 4 - converts [common named data types](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.0.0.md#data-types) to `type` and `format` - for example `type: "dateTime"` becomes `type: "string"` with `format: "date-time"` - deletes `nullable` and adds `"null"` to `type` array if `nullable` is `true` - supports deep structures with nested `allOf`s etc. - removes [OpenAPI specific properties](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.0.0.md#fixed-fields-20) such as `discriminator`, `deprecated` etc. unless specified otherwise - optionally supports `patternProperties` with `x-patternProperties` in the Schema Object **NOTE**: `$ref`s are not dereferenced. Use a dereferencer such as [json-schema-ref-parser](https://www.npmjs.com/package/json-schema-ref-parser) prior to using this package.
