Traversing a JSON Schema

This feature allows you to traverse a JSON Schema and execute a callback function at each node. The callback receives information about the current schema node, its path, and its context within the overall schema.

{"schema": {"type": "object", "properties": {"foo": {"type": "string"}, "bar": {"type": "number"}}}, "callback": "(schema, jsonPtr, rootSchema, parentJsonPtr, parentKeyword, parentSchema, keyIndex) => { console.log('Traversing:', jsonPtr); }"}

Modifying a JSON Schema during traversal

This feature allows you to modify the schema nodes during traversal. For example, you can add constraints like 'minLength' to string properties.

{"schema": {"type": "object", "properties": {"foo": {"type": "string"}, "bar": {"type": "number"}}}, "callback": "(schema, jsonPtr, rootSchema, parentJsonPtr, parentKeyword, parentSchema, keyIndex) => { if (schema.type === 'string') { schema.minLength = 1; } }"}
