1. What is a Chrome Extension?

A Chrome extension is a small software module that customizes your browsing experience. These extensions enhance browser functionality and can range from tools that block ads to those that summarize web content.

2. Getting Started with Your Extension

Creating a Chrome extension involves setting up some essential files:

• popup: This directory will hold the .html file for your extension's popup.
• scripts: This directory will contain the .js file, which includes the logic for the buttons and summarization.
• styles: This directory will contain the .css file for styling your extension.
• manifest.json: This file contains essential metadata about your extension.

3. Creating the Manifest File

The manifest.json file is crucial as it provides details about your extension. Here is a basic example of how your manifest.json file could look:

{
  "manifest_version": 3,
  "name": "Article Summarization Extension",
  "version": "1.0",
  "description": "Summarizes articles using AI",
  "background": {
    "service_worker": "scripts/index.js"
  },
  "permissions": ["activeTab"],
  "action": {
    "default_popup": "popup/popup.html",
    "default_icon": "icon.png"
  },
  "content_scripts": [
    {
      "matches": ["*://medium.com/*"],
      "js": ["scripts/index.js"],
      "css": ["styles/index.css"]
    }
  ]
}  

4. Adding Styles and Scripts

In the styles/index.css file, you can define styles for the buttons you'll use for summarization:

button {
  background-color: #007bff;
  color: white;
  border: none;
  padding: 10px;
  cursor: pointer;
}

button:hover {
  background-color: #0056b3;
}

5. Structuring the Code

In the scripts/index.js file, you will add logic for generating buttons that trigger the summarization:

function createSummarizationButton() {
    const button = document.createElement('button');
    button.innerText = 'Summarize Article';
    button.onclick = summarizeArticle;
    document.body.appendChild(button);
}

6. Loading Buttons on the Page

We'll ensure that buttons are added to the article when the page loads, utilizing event listeners:

window.onload = function() {
   if (isArticlePage()) {
      createSummarizationButton();
   }
};

7. Making Requests for Summarization

Here's where the magic happens: linking your button click to the Cohere API to fetch the article summary:

async function summarizeArticle() {
   const articleContent = extractArticleContent();
   const summary = await cohereReq(articleContent);
   console.log(summary);
}

8. Testing Your Extension

To load the extension in Chrome, navigate to:

1. Go to chrome://extensions.
2. Enable Developer mode.
3. Click on Load unpacked and select your extension folder.

Now, head over to Medium and try out your new extension!
