What is acorn-jsx?

The acorn-jsx npm package is a plugin for the Acorn JavaScript parser that allows it to parse JSX syntax. JSX is a syntax extension for JavaScript commonly used with React to describe what the UI should look like. By using acorn-jsx, developers can extend the Acorn parser to handle JSX elements as part of the JavaScript code, enabling the development of tools like linters, code formatters, and compilers that work with JSX.

What are acorn-jsx's main functionalities?

JSX Parsing

This feature allows the parsing of JSX syntax by extending the Acorn parser. The code sample demonstrates how to create a new parser instance that can parse a string containing JSX code and output the abstract syntax tree (AST).

const acorn = require('acorn');
const jsx = require('acorn-jsx');
const JSXParser = acorn.Parser.extend(jsx());
const code = `<div>Hello, world!</div>`;
const ast = JSXParser.parse(code, {ecmaVersion: 2020});
console.log(ast);
