Parsing Lambda Error Logs in ReScript & Python
That coginitive dissonance is why I wrote this article. I love how both laguages can shine in what they do best doing the same task, and it’s fascinating to compare them, and how you’d approach doing the same thing in each. For reference, all code is up on my Github.

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.

ReScript JSON Typed Strongly
To build a solid JSON codec layer I use Jzon library (disclosure: I’m the author of Jzon). Here are codecs which do the job for our ingredient list:
What are some alternatives?

rescript-apollo-client - ReScript bindings for the Apollo Client ecosystem
aws-cloudformation-coverage-roadmap - The AWS CloudFormation Public Coverage Roadmap
CPython - The Python programming language
TypeScript - TypeScript is a superset of JavaScript that compiles to clean JavaScript output.
ajv - The fastest JSON schema Validator. Supports JSON Schema draft-04/06/07/2019-09/2020-12 and JSON Type Definition (RFC8927)
ocaml - The core OCaml system: compilers, runtime system, base libraries
