fouwels / noctilucent

A cloudformation json -> cdk typescript transpiler.

noctilucent

In a world where people want to use the full extent of the cdk, there was no product that would transform all your JSON/YAML into beautiful typescript...until now.

Noctilucent will take your JSON/YAML and output the equivalent typescript.

User Guide

$ cargo build --release
$ ./target/release/noctilucent [INPUT] [OUTPUT]

• INPUT is the input file path (STDIN by default).
• OUTPUT is the output file path; if not specified, output will be printed on your command line (STDOUT by default).
