If the documents in a collection have varying structures, the generated schema may not accurately represent all possible data shapes. Nested objects and arrays are supported up to a maximum depth of 5 levels to avoid potential circular references. This depth can be adjusted in the utils.ts file...
Each key in ourblogSchemadefines a property in our documents which will be cast to its associatedSchemaType. For example, we've defined atitlewhich will be cast to theStringSchemaType anddatewhich will be cast to aDateSchemaType. Keys may also be assigned nested objects containing further key...
