Unleashing the Power of Tampermonkey: Customizing Website UI for Enhanced Productivity

As a web developer, you likely spend a significant amount of time interacting with various websites and web applications. While these websites are designed to cater to a broad audience, there may be instances where you wish to customize the user interface (UI) to better suit your specific needs and preferences. This is where Tampermonkey comes into play.

Tampermonkey is a powerful browser extension that allows you to inject custom JavaScript and CSS into web pages, enabling you to modify and enhance the functionality and appearance of websites. With Tampermonkey, you can create userscripts that run automatically on specified websites, giving you full control over the UI and behavior.

In this article, we‘ll explore how to leverage Tampermonkey to improve a website‘s UI, using freeCodeCamp as an example. We‘ll walk through the process of installing Tampermonkey, creating userscripts, and implementing various customizations to enhance productivity and usability. Let‘s get started!

Installing Tampermonkey

To begin, you‘ll need to install the Tampermonkey extension in your browser. Tampermonkey is available for major browsers such as Chrome, Firefox, Safari, and Edge. Visit the Tampermonkey website (https://www.tampermonkey.net/) and follow the installation instructions specific to your browser.

Once installed, you‘ll see the Tampermonkey icon in your browser‘s toolbar. Clicking on the icon will open the Tampermonkey dashboard, where you can manage your userscripts and access various settings.

Creating a New Userscript

To create a new userscript, click on the Tampermonkey icon and select "Create a new script" from the menu. This will open the Tampermonkey script editor with a template for a basic userscript.

The userscript begins with a metadata block enclosed in ==UserScript== comments. Here, you can specify various details about your script, such as its name, version, description, and the websites it should run on. For our example, let‘s target the freeCodeCamp website by setting the @match directive to https://www.freecodecamp.org/*.

Modifying Button Functionality

One common customization is modifying the behavior of existing buttons on a website. Let‘s take the "Tweet a thanks" button at the end of freeCodeCamp articles as an example. By default, clicking this button opens a pre-populated tweet mentioning the author. However, we can customize it to include additional information or change the tweet‘s format.

To locate the relevant button, we can use the browser‘s developer tools to inspect the element. In this case, the button has an ID of "tweet-btn". We can select this button using JavaScript and modify its click event handler.

Here‘s an example of how we can change the tweet‘s text to include the article‘s title and URL:

document.getElementById(‘tweet-btn‘).addEventListener(‘click‘, function(event) {
  event.preventDefault();

  const articleTitle = document.querySelector(‘h1‘).textContent;
  const articleUrl = window.location.href;

  const tweetText = `Just read "${articleTitle}" on freeCodeCamp! ${articleUrl}`;
  const tweetUrl = `https://twitter.com/intent/tweet?text=${encodeURIComponent(tweetText)}`;

  window.open(tweetUrl, ‘_blank‘);
});

In this code, we prevent the default button behavior, extract the article title and URL, construct the desired tweet text, and open a new window with the pre-populated tweet.

Implementing Reader View

When reading lengthy articles, it can be helpful to have a distraction-free reading experience. We can implement a reader view that hides unnecessary elements and focuses solely on the article content.

To achieve this, we can use CSS to selectively hide elements based on their class names or IDs. For example, we can hide the navigation bar, sidebar, and footer while keeping the main article container visible.

Here‘s an example CSS code snippet:

.header,
.sidebar,
.footer {
  display: none !important;
}

.article-container {
  width: 100% !important;
  max-width: 800px !important;
  margin: 0 auto !important;
  padding: 20px !important;
}

We can inject this CSS using Tampermonkey‘s GM_addStyle function:

GM_addStyle(`
  .header,
  .sidebar,
  .footer {
    display: none !important;
  }

  .article-container {
    width: 100% !important;
    max-width: 800px !important;
    margin: 0 auto !important;
    padding: 20px !important;
  }
`);

With this customization, the reader view will be applied automatically when visiting freeCodeCamp articles, providing a cleaner and more focused reading experience.

Adding Copy Buttons to Code Snippets

When reading technical articles, it‘s common to come across code snippets that you may want to copy for reference or experimentation. Instead of manually selecting and copying the code, we can enhance the UI by adding copy buttons to each code snippet.

To accomplish this, we can identify the code snippets on the page using CSS selectors and inject copy buttons next to them. Here‘s an example implementation:

// Find all code snippets
const codeSnippets = document.querySelectorAll(‘pre code‘);

// Iterate over each code snippet
codeSnippets.forEach(snippet => {
  // Create a copy button
  const copyButton = document.createElement(‘button‘);
  copyButton.textContent = ‘Copy‘;
  copyButton.classList.add(‘copy-button‘);

  // Add click event handler to copy the code
  copyButton.addEventListener(‘click‘, () => {
    const code = snippet.textContent;
    navigator.clipboard.writeText(code).then(() => {
      copyButton.textContent = ‘Copied!‘;
      setTimeout(() => {
        copyButton.textContent = ‘Copy‘;
      }, 2000);
    });
  });

  // Insert the copy button before the code snippet
  snippet.parentNode.insertBefore(copyButton, snippet);
});

In this code, we find all code snippets using the pre code selector, create copy buttons for each snippet, and add a click event handler to copy the code to the clipboard when the button is clicked. We also provide visual feedback by changing the button text to "Copied!" for a short duration after copying.

To style the copy buttons, we can add some CSS:

.copy-button {
  position: absolute;
  top: 10px;
  right: 10px;
  padding: 5px 10px;
  background-color: #f0f0f0;
  border: none;
  border-radius: 4px;
  cursor: pointer;
}

.copy-button:hover {
  background-color: #e0e0e0;
}

Now, each code snippet will have a convenient copy button, making it easier for readers to copy and use the code samples.

Auto-Generating Table of Contents

For lengthy articles with multiple sections and subsections, navigating through the content can be challenging. To improve navigation and provide a quick overview of the article structure, we can auto-generate a table of contents based on the heading elements (h1, h2, h3, etc.).

Here‘s an example of how we can generate a table of contents:

// Find all heading elements
const headings = document.querySelectorAll(‘h1, h2, h3, h4, h5, h6‘);

// Create a container for the table of contents
const tocContainer = document.createElement(‘div‘);
tocContainer.id = ‘toc-container‘;

// Create a heading for the table of contents
const tocHeading = document.createElement(‘h2‘);
tocHeading.textContent = ‘Table of Contents‘;
tocContainer.appendChild(tocHeading);

// Create an unordered list for the table of contents
const tocList = document.createElement(‘ul‘);
tocContainer.appendChild(tocList);

// Iterate over each heading
headings.forEach(heading => {
  // Create a list item for each heading
  const listItem = document.createElement(‘li‘);

  // Create a link to the heading
  const link = document.createElement(‘a‘);
  link.textContent = heading.textContent;
  link.href = `#${heading.id}`;

  // Append the link to the list item
  listItem.appendChild(link);

  // Append the list item to the table of contents
  tocList.appendChild(listItem);
});

// Insert the table of contents container before the main content
const mainContent = document.querySelector(‘.main-content‘);
mainContent.insertBefore(tocContainer, mainContent.firstChild);

In this code, we find all heading elements, create a container for the table of contents, and generate an unordered list with links to each heading. We then insert the table of contents container before the main content of the article.

To style the table of contents, we can add some CSS:

#toc-container {
  margin-bottom: 20px;
  padding: 20px;
  background-color: #f0f0f0;
  border-radius: 4px;
}

#toc-container h2 {
  margin-top: 0;
}

#toc-container ul {
  list-style-type: none;
  padding-left: 20px;
}

#toc-container li {
  margin-bottom: 10px;
}

#toc-container a {
  text-decoration: none;
  color: #333;
}

#toc-container a:hover {
  text-decoration: underline;
}

With this customization, readers can quickly navigate to specific sections of the article using the auto-generated table of contents.

Additional Customization Ideas

The examples we covered are just a few ways you can use Tampermonkey to customize a website‘s UI. Here are some additional ideas to inspire you:

• Add keyboard shortcuts for common actions or navigation.
• Customize the font size, color scheme, or layout to improve readability.

The possibilities are endless, and Tampermonkey provides a flexible and powerful way to tailor websites to your specific needs and preferences.

Best Practices and Considerations

When creating userscripts with Tampermonkey, there are a few best practices and considerations to keep in mind:

1. Be mindful of website terms of service and usage policies. Some websites may have restrictions on modifying their UI or using third-party scripts.

2. Ensure your userscripts are compatible with the target website‘s structure and selectors. Websites may change over time, so it‘s important to regularly test and update your scripts.

3. Consider performance and efficiency when writing your scripts. Avoid unnecessarily complex or resource-intensive modifications that could slow down the website.

4. Use clear and descriptive names for your userscripts and include comments to document their purpose and functionality.

5. Be cautious when handling sensitive data or interacting with forms and inputs. Ensure your scripts don‘t unintentionally expose or modify user data.

6. Share your userscripts with the community and learn from others. Websites like Greasy Fork (https://greasyfork.org/) and OpenUserJS (https://openuserjs.org/) are great platforms for discovering and sharing userscripts.
