render abstract syntax trees using react
Please ★ this repo if you found it useful ★ ★ ★
Abstract syntax trees are difficult to work with by nature. This is a react renderer that makes interacting with abstract syntax trees and rendering code a breeze.
React AST is the ultimate meta programming tool that uses react to render abstract syntax trees. It can be used to build powerful unopinionated code generators and babel plugins that are easy to read and can scale without creating a rats nest of unreadable code.
You can read a post I wrote about this project at the link below.

Features
- works with babel ast
- supports typescript
Installation
npm install --save react-ast
Dependencies
Usage
Render Code
import React, { FC } from "react";
import {
Export,
Expression,
Function,
Identifier,
Import,
Interface,
JSX,
ReactNode,
Return,
TypeAnnotation,
TypeReference,
Var,
VarKind,
} from "react-ast";
const code = await render(
<>
<Import default="React" imports={["FC"]} from="react" />
<Export>
<Interface name="HelloProps" />
</Export>
<Var kind={VarKind.Const} typeAnnotation="FC<HelloProps>" name="Hello">
<Function
arrow
params={[
<Identifier
typeAnnotation={
<TypeAnnotation>
<TypeReference name="HelloProps" />
</TypeAnnotation>
}
>
props
</Identifier>,
]}
>
<Return>
<JSX />
</Return>
</Function>
</Var>
<Expression properties="Hello.defaultProps">{{}}</Expression>
<Export default>
<Identifier>Hello</Identifier>
</Export>
</>
);
console.log(code);
The rendered code
import React, { FC } from "react";
export interface HelloProps {}
const Hello: FC<HelloProps> = (props: HelloProps) => {
return <></>;
};
Hello.defaultProps = {};
export default Hello;
Render AST
Sometimes you might want to render the ast instead of rendering the code.
import React from "react";
import { ClassDeclaration, renderAst } from "react-ast";
const ast = renderAst(<Class name="Hello" />);
console.log(ast);
The rendered AST
{ type: 'File',
program:
{ type: 'Program',
body: [ [Object] ],
directives: [],
sourceType: 'script',
interpreter: null },
comments: [],
tokens: [] }
