Deserialization

Deserialization is the process of taking a serialized format, like JSON or XML, and turning it back into a rich object hierarchy your program can use. It's the opposite of serialization, which is like packing all your stuff into boxes before a move, while deserialization is like unpacking everything and putting it in its proper place in your new digs.

How to use it in a sentence

  • I spent all day debugging an issue that turned out to be due to deserialization barfing on some malformed JSON from the new intern's API.

  • After getting paged at 3am because deserialization was failing in prod, I decided it was time to update my resume and look for a new gig without so much technical debt.

If you actually want to learn more...

  • Martin Fowler has an insightful article on the pitfalls of automatic deserialization and the benefits of hand-coding it instead to avoid tightly coupling services:

Enterprise Integration Using REST

  • For a deep dive into how deserialization is handled in popular binary formats like Avro, Protocol Buffers, and Thrift, check out this post that compares how they handle schema evolution:

Schema Evolution in Avro, Protocol Buffers and Thrift

  • And if you really want to nerd out on deserialization patterns, Fowler's site has a whole collection of articles on topics like refactoring serialization code, dependency injection, and domain-driven design:

We evaluated Optimizely, LaunchDarkly, Split, and Eppo, but ultimately selected Statsig due to its comprehensive end-to-end integration. We wanted a complete solution rather than a partial one, including everything from the stats engine to data ingestion.
