    A lightweight DOM manipulation tool

    What do I use this for?

    Writing significantly more maintainable, condensed, and readable code. For example: Without good-dom:

    <!-- HTML and vanilla javascript -->
    <body style="width: 100vw; display:flex; flex-direction: column; align-items: center">
        Hello There
        <div id="blahDiv"></div>
        <input id="blahInput" placeholder="type something"/>
    <script type="text/javascript">
        // get the input box
        var blahInput = document.getElementById("blahInput")
        blahInput.oninput = function(eventObject) {
            // get the value
            var inputBoxContent =
            // put the value in a div
            var blahDiv = document.getElementById("blahDiv")
            blahDiv.innerText = inputBoxContent

    Equivalent output using good-dom:

    <!-- good-dom without JSX -->
    <!-- (copy and paste this into a .html file an open it and it will work) -->
    <script src=""></script>
    <script type="text/javascript">
        document.body = new BODY({style: { width: "100vw", display: "flex", flexDirection: "column", alignItems: "center"} },
            "Hello there",
            blahDiv = new DIV({}, "Im an inner box"),
            blahInput = new INPUT({
                placeholder:"type something", 
                oninput: (eventObject) => blahDiv.innerText =

    I'm getting an error, how do I fix it?

    If you're creating a custom html element and you're getting errors about "Type error ... must use |new|", this is a problem with babel/transpiling/polyfilling classes to ES5 classes. As Mozilla MDN points out, there is no way to perfectly transpile custom component classes back to ES5. To fix this, add a setting to your transpiler to avoid converting ES6 classes to ES5 classes. If you don't know how to do that, a quick fix is to add "browserslist": "last 2 Chrome versions", to your package.json, however this means your transpiled code will now only officially support modern browsers.
