JSON to TF

Convert CDKTF formatted JSON to Terraform.

Example Use

Input

CDKTF formatting allows for multiple sub objects with the same key. In order to ensure this is possible within JavaScript, CDKTF JSON data must be stringified.

const jsonToTf = require("json-to-tf");

Using Within Compiled JavaScript

A browserified Stream and Buffer must be added to the window object in order for json-to-tf to work within a webpack compiled front-end library.
