jcast-util-from-json

jcast utility to parse JSON Canvas into a jcast syntax tree.

What is this?

This package contains a utility to parse JSON Canvas into a syntax tree. The resulting syntax tree can be used to read and manipulate the JSON Canvas. In contrast to the JSON Canvas Spec, the syntax tree groups elements inside groups together and allows for easier manipulation using the unist ecosystem. To serialize the syntax tree back to JSON Canvas, use jcast-util-to-json.

When to use this

You can use this utility when you want to work with JSON Canvas in a syntax tree.

If you just want to parse JSON Canvas into a type-safe object, use jsoncanvas instead.

Install

This package is ESM only. In Node.js (version 18+), install with npm:

npm install @moritzrs/jcast-util-from-json

const tree = fromJson(json);

	console.log(group.value);
