Question 1

How to handle circular references with json-schema-ref-parser?

Accepted Answer

The library automatically detects and handles circular references by maintaining object references, preventing infinite loops. You can use it out of the box, as described in the documentation for complex schemas.

Question 2

What's the difference between bundling and dereferencing in JSON Schema $Ref Parser?

Accepted Answer

Bundling consolidates multiple files into a single schema with internal $ref pointers, while dereferencing resolves all pointers to produce a plain JavaScript object. Choose bundling for distribution and dereferencing for easy access to schema data.

Question 3

json-schema-ref-parser vs ajv for schema validation?

Accepted Answer

json-schema-ref-parser focuses on resolving $ref pointers and dereferencing schemas, while Ajv is a validator that handles references but optimizes for speed. Use json-schema-ref-parser to prepare schemas and Ajv for validation against the resolved output.

Question 4

How to use json-schema-ref-parser in a browser with webpack?

Accepted Answer

Configure Webpack with fallbacks for path and fs modules, and provide Buffer polyfills, as detailed in the README's browser support section. This ensures compatibility with Node.js core modules in browser environments.

Question 5

Does json-schema-ref-parser support YAML files out of the box?

Accepted Answer

Yes, it natively supports YAML schemas alongside JSON, including mixed formats, without additional configuration. This is a key feature for teams working with diverse schema definitions.

Question 6

How to avoid modifying the original schema when dereferencing?

Accepted Answer

Set the mutateInputSchema option to false when calling dereference, which returns a cloned schema. This prevents in-place modifications, as shown in the example code in the README.
