This project leverages the react-reconciler to allow users to serialize JSX trees into JSON objects.

---

Install

yarn add react-json-reconciler
npm i --save react-json-reconciler

Usage

There are 4 primitive JSX elements, that can be used to construct a normal JSX tree. All the things you'd expect to have access to in React (state, hooks props) all work as they normally would. To serialize the elements into JSON, call render and await the response. This will wait for all useEffect and setState updates to settle before returning the result.

import React from "react";
import { render } from "react-json-reconciler";

const element = (
  <obj>
    <property key="Prop 1">
      <array>
        <value>Value 1</value>
      </array>
    </property>
    <property key="Prop 2">Value 2</property>
  </obj>
);

const { jsonValue } = await render(element);

The above will generate

{
  "Prop 1": ["Value 1"],
  "Prop 2": "Value 2"
}

Source Maps

In order to generate source-map support, React must be in development mode (process.env.NODE_ENV != 'production'), and the @babel/plugin-transform-react-jsx-source plugin enabled (included as part of @babel/preset-react)

Pass the collectSourceMap: true option to the render method.

Refs

For each of the primitive types, any ref will return a respective JSON AST node. This allows users to introspect and manipulate the tree before rendering when coupled with a useEffect() or useLayoutEffect().

Example:

import React from "react";

const CustomComponent = (props) => {
  const objRef = React.useRef(null);

  React.useEffect(() => {
    // A chance to introspect the JSON AST node before being serialized
  }, [objRef]);

  return <obj ref={objRef}>{props.children}</obj>;
};
