What is json-schema-ref-parser?
The json-schema-ref-parser npm package is a tool that can parse JSON Schema files and dereference $ref pointers. This allows you to combine multiple separate JSON Schema files into one resolved schema, validate JSON documents against schemas, and manipulate JSON Schemas programmatically.
What are json-schema-ref-parser's main functionalities?
Dereferencing $ref pointers
This feature allows you to take a JSON Schema that contains $ref pointers to other files or URLs and resolve them into a single JSON Schema object. This is useful for simplifying and flattening schemas that are spread across multiple files.
{"$ref": "http://example.com/my-schema.json"}
Bundle schemas into a single file
This feature lets you take a JSON Schema with $ref pointers to other files in your project and bundle them all into a single JSON Schema file. This can be useful for distribution or for loading a schema from a single file in a browser or other environments where multiple files are not convenient.
{"$ref": "definitions.json#/address"}
Parse JSON Schema to a JavaScript object
This feature allows you to parse a JSON Schema from a string, file, or URL into a JavaScript object. This can be useful for manipulating the schema programmatically or for using it in conjunction with other tools that operate on JavaScript objects.
{"type": "object", "properties": {"name": {"type": "string"}}}

json-schema
The json-schema package is another tool for validating JSON data against JSON Schemas. It is similar to json-schema-ref-parser in that it can parse and validate schemas, but it does not have the same focus on resolving $ref pointers.
tv4
Tiny Validator (tv4) is a small and fast JSON Schema validator. It is similar to json-schema-ref-parser in that it can validate JSON documents against schemas, but it does not provide the same level of support for dereferencing and bundling schemas.
