Parsing Lambda Error Logs in ReScript & Python
We need the Promise library as it is the best way to use Promises in ReScript. We utilize the Jzon library for deterministically parsing our JSON into sound ReScript types without using the super verbose Js.Json classify syntax. Finally, we have an Environment module to help our Lambda know if it’s running in a QA, Stage, or Production environment.

Which Language?
For promises, there's a proposal plus implementation with improvements that should be upstreamed soon. JS interop is actually pretty good, if you find the embedding syntax too ugly you can for the most part keep .js files and .res files and they'll work together.

Thinking in ReScript
Note that here I'm using the rescript-promise library, which will soon become a part of the core language.
