Description

JSONLogic is used as the basis for all our flagd implementations (the evaluator inside the flagd bin/daemon itself, and inside the in-process providers). However, JSONLogic implementations have some noted inconsistencies. Not all of them may impact us, and some of them might have workarounds (ie: we can avoid support for some shorthands with our schema).

We need to enumerate and understand these, and then:

  • File relevant issues
  • Brainstorm solutions (e.g. WASM module, etc)

Research direction

Start with the JSON Logic compatibility tables, then compare their findings against the evaluator in the flagd bin/daemon and the in-process providers. Document which inconsistencies affect flagd, note possible schema workarounds, file relevant issues, and record solution ideas such as a WASM module.
