Bubble.io plugin with Preact.js

About:

This is a simple proof-of-concept to set up a viable development workflow to build a Bubble plugin element using Preact.js. The aim is to allow plugin developers to break out of the limited Bubble plugin SDK.

Write up:

Steps to reproduce:

• Clone this repository, run yarn to install dependencies.

• Create a Bubble plugin. You can also fork this plugin to skip the next Bubble plugin setup steps.

  • Add this piece of code into the shared header of Bubble:

    <script>
    function loadJS(url, module = false) {
        let scriptEle = document.createElement("script");
        scriptEle.setAttribute("src", url);
        scriptEle.setAttribute("type", module ? "module" : "text/javascript" );
        document.head.appendChild(scriptEle);
    }
    
    function loadCSS(url) {
        let link = document.createElement("link");
        link.rel  = 'stylesheet';
        link.type = 'text/css';
        link.href = url;
        link.media = 'all';
        document.head.appendChild(link);
    }
    
    window.devServerURL = "_*_DEV_SERVER_URL_*_";
    if (!!window.devServerURL) {
        loadJS(window.devServerURL + "/index.umd.js");
        loadCSS(window.devServerURL + "/style.css");
    }
    </script>
    

  • Add a new Bubble plugin element. Set the update function as below:

    function(instance, properties, context) {
        if (!instance.data.element) {
            instance.data.element = document.createElement("custom-counter");
            instance.canvas.append(instance.data.element);
        }
        instance.data.element.properties = properties;
    }
    

• Add the plugin into a test app, and set the DEV_SERVER_URL plugin key to be http://localhost:3000.

• Put the new Bubble element in your test app.

• Run yarn dev on your machine.

• Open test app.

Caveats

• No hot reload right now. When you update the Preact code, you need to reload the browser tab again.
• Speed optimization is still in question.
