Enhancing application performance with serialization
The serialization step converts the high-level data generated by business logic, including JSON objects or errors, into low-level data, such as strings or buffers, which are then sent as responses to the client’s requests. It involves the transformation of intricate objects into an appropriate data type that can be effectively transmitted to the client. In fact, as mentioned in the Implementing authentication with hooks recipe, the serialization process is initiated only if the route handler doesn’t return a string, stream, or buffer, as these objects are already serialized and prepared for transmission as HTTP responses to the client. Nevertheless, this process can’t be avoided when you work with JSON objects.
Fastify incorporates a serialization module that facilitates the conversion of an object into a JSON string, leveraging a JSON schema definition. This module, known as fast-json-stringify, offers a...
