ffjson

For json schema specifically there are some tools like go-jsonschema[1] but I've never used them personally. But you can use something like ffjson[2] in go to generate a static serialize/deserialize function based on a struct definition. [1] https://github.com/omissis/go-jsonschema [2] https://github.com/pquerna/ffjson

I have been using ffjson[1] in a couple of private projects, which generates code to encode/decode data, which supposedly is faster than the json library from Go's standard library. Has somebody any first-hand expertise how this compares to the competition? (I could, of course, do my own benchmarks, but so far I have not had any performance issues on this end, so it has not been a pressing need. The only problem I have run into with ffjson is that various linters will bark at the generated code, but again, that has not been a big problem.) [1] https://github.com/pquerna/ffjson

I found the mention of ffjson interesting, a faster serializer then the standard buildin json serializer ( 2x - 3x as fast) ==> https://github.com/pquerna/ffjson

Which libraries have you looked at? https://github.com/pquerna/ffjson and https://github.com/benbjohnson/megajson claim to be faster

There's already tools in Go for meta-programming. In fact coincidentally I was reading about a few of these tools earlier today [1][2][3] - but personally I don't like that approach.

This. If your main use case is JSON as a serialized representation of the ever same object (plus or minus a few optional fields), encoding/json is by far the fastest and most typesafe way to go. (edit: Protip - for the really really fastest way to demarshal JSON, look here https://github.com/pquerna/ffjson for some reflection-free extra speed after your code has settled down) But if your objects can be heterogenous for whatever reasons (think third-party systems, different languages, legacy stacks...) or you're dealing with different kinds of objects landing on the same controller, jason is the perfect complimentary device to deal with more dynamic structures. I've long sought for something like this, thanks to the OP!
