This may information you thru Vue chrome extension improvement.
This information is focused in the direction of builders who’ve a fundamental understanding of Javascript, HTML, and CSS and have some fundamental understanding of Vue.js framework.
Stipulations
Earlier than embarking in your Vue.js Chrome extension journey, guarantee you’ve got the required instruments and information.
First, you will want:
- Node.js: A JavaScript runtime atmosphere.
- npm or yarn: Package deal managers for putting in dependencies.
- A Textual content Editor or IDE: Visible Studio Code, Elegant Textual content, or any code editor of your alternative.
Moreover, a foundational grasp of the next ideas is important:
- HTML, CSS, and JavaScript: The constructing blocks of internet improvement.
- Vue.js: Understanding elements, knowledge binding, and occasion dealing with is essential.
- Chrome Extension Structure: Familiarize your self with the roles of `manifest.json`, background scripts, content material scripts, and the popup interface.
Mission Setup
Let’s start by structuring our venture and configuring the required instruments.
First, create the listing in your venture. Inside, set up the next construction:
- `/src`: This listing will home your Vue.js code, together with elements and logic.
- `/public`: This listing will include static property like HTML, CSS, photos, and the essential `manifest.json` file.
Subsequent, initialize a Vue.js venture inside the `/src` listing utilizing the Vue CLI or your most popular methodology. For instance, utilizing Vue CLI:
vue create src
Configure a bundler reminiscent of Webpack to optimize your Vue.js code for Chrome extension improvement. Key configurations embrace specifying the output listing (e.g., `/dist`) and making certain the `manifest.json` file is copied to the output listing through the construct course of.
Now, let’s craft the `manifest.json` file, the blueprint of your Chrome extension. This file declares the extension’s metadata, permissions, and entry factors.
Necessary fields inside `manifest.json` embrace:
- `title`: The title of your extension (displayed within the Chrome Internet Retailer and extension administration web page).
- `description`: A concise description of your extension’s performance.
- `model`: The model variety of your extension.
- `manifest_version`: Specifies the manifest file model (often `3` for contemporary extensions).
- `permissions`: An array itemizing the permissions your extension requires (e.g., `activeTab`, `storage`, `notifications`). Solely request the permissions that you simply really want.
- `browser_action` or `page_action`: Defines the conduct of the extension’s icon within the Chrome toolbar.
- `background`: Configures the background script, which runs within the background and handles occasions.
- `content_scripts`: Specifies scripts that inject into internet pages.
Here is a fundamental instance of a `manifest.json` file:
{
"manifest_version": 3,
"title": "My Vue Chrome Extension",
"model": "1.0",
"description": "A easy Chrome extension constructed with Vue.js",
"permissions": [
"activeTab",
"storage"
],
"motion": {
"default_popup": "popup.html",
"default_title": "My Extension"
},
"background": {
"service_worker": "background.js"
}
}
Constructing the Extension UI with Vue.js
Now, let’s create the consumer interface in your extension utilizing Vue.js. A standard place to begin is a popup UI that seems when the extension icon is clicked.
Develop Vue elements for the popup, incorporating knowledge binding and occasion dealing with to create dynamic and interactive components. Use CSS or a CSS framework like Tailwind CSS or Bootstrap to model the UI and make it visually interesting.
Here is a easy instance of a popup that shows the present URL of the lively tab.
In `popup.html` (inside the `/public` listing):
<!DOCTYPE html>
<html>
<head>
<title>My Extension Popup</title>
<hyperlink rel="stylesheet" href="model.css">
</head>
<physique>
<div id="app"></div>
<script src="popup.js"></script>
</physique>
</html>
In `src/elements/PopupComponent.vue`:
<template>
<div>
<h1>Present URL:</h1>
<p>{{ currentUrl }}</p>
</div>
</template>
<script>
export default {
knowledge() {
return {
currentUrl: 'Loading...'
};
},
mounted() {
chrome.tabs.question({ lively: true, currentWindow: true }, (tabs) => {
this.currentUrl = tabs[0].url;
});
}
};
</script>
In `src/popup.js`:
import { createApp } from 'vue'
import PopupComponent from './elements/PopupComponent.vue'
createApp(PopupComponent).mount('#app')
Content material Script Injection & Communication (Elective)
Content material scripts are highly effective instruments that let you work together with the content material of internet pages. These scripts can entry and modify the DOM, enabling you so as to add customized performance or extract info from web sites.
To inject a content material script into internet pages, that you must specify it within the `manifest.json` file. For instance:
"content_scripts": [
{
"matches": ["<all_urls>"],
"js": ["content.js"]
}
]
