mxn-canvas-ui

HTML5 Canvas based UI Components

• ~5.5kb size
• ~2.5kb minified + gzipped

Usage

We suggest you to load the module via require until the stabilization of ES modules in Node.js:

const transform = require("mxn-canvas-ui");

Now you can transform all JSX elements into JS calls like this:

let ast = transform(jsx_ast, { factory: "h" });

Where

• jsx_ast {Object} - ESTree-compilant JSX AST to transform to regular JS AST
• factory {String} - factory function to use, e.g. h, m, React.createElement

Please note that this tool only converts JSX AST into regular ES5-compliant JavaScript AST. If you want to transpile your source code, check out mxn-jsx-transpiler or use a code like:

// Acorn & Astring
const acorn = require("acorn");
const acornJsx = require("acorn-jsx");
const { generate } = require("astring");

// JSX AST Transformer
const transform = require("jsx-ast-transformer");

// Create parser
let parser = acorn.Parser.extend(acornJsx({
    allowNamespaces: false
}) );

let code = 'let a = <Greeting firstName="Maximilian" lastName="Pierpont" age={1 + 2 + 3 + 4} />;';

let ast = parser.parse(code, {
    ecmaVersion: 2020,
    sourceType: "module",
    locations: false,
    plugins: { jsx: true }
});

// Transform AST
let ast_new = transform(ast, { factory: "h" });

// Generate code
let transformedCode = generate(ast_new, {
    indent: "    ",
    lineEnd: "\n",
    comments: false
});
