Nice browser. Is it antique?
No, seriously - your browser is so old that some features of patternplate don't work as expected.
Don't worry - you can either continue with a restricted version or install an up-to-date browser.

You are ready for advanced features of Stickyroll

Time invest: 5 Minutes ––– 👩‍🎓 Level: Intermediate

What to expect

Sometimes it is hard to build additional features into existing libraries. Stickyroll provides various options to make this very easy. In about 5 minutes we will build a small PageCounter that displays the current page.

We will …

  • … install an additional stickyroll package
  • … create a new file with a component
  • … add the component to our existing app

You'll need

You should have finished at least the first course.

Building plugins with decorators

Follow these 3 simple steps to build your first Plugin.

1. Installing Decorators

While in your app folder my-app, run a single command:

npm install --save @stickyroll/decorators

2. Creating a Plugin

Create a file my-app/src/PageCounter.js in your text editor and paste this code.

import { page } from "@stickyroll/decorators";
import React from "react";

class PageCounter extends React.Component {
    render() {
        return (
                <strong>{}</strong>{" "}
                of{" "}

export default page(PageCounter);

3. Using the plugin

We can now use the plugin to replace our previously local implementation.

All we need to do is replace the following section

<strong>{page}</strong> of <strong>{pages}</strong>

with this new Snippet


and import our plugin

import PageCounter from "./PageCounter";

Your App.js should now look like this:

import React from 'react';
import {Stickyroll} from '@stickyroll/stickyroll';
import PageCounter from "./PageCounter";

const headlines = [
    "Hello World!",
    "Hello React!",
    "Hello Stickyroll!",
    "Let's continue with the next lesson!"

const App = () => {
    return (
        <Stickyroll pages={headlines}>
            {({pageIndex, progress}) => {
                return (
                    Progress: <strong>{progress}</strong>

export default App;


Next steps

You can now repeat the same process with {progress} from "@stickyroll/decorators".

In this case we want to replace

Progress: <strong>{progress}</strong>

with this new snippet


You should now be able to do this on your own.

You can now continue with this course.
