Methods to Download Instagram Videos with JavaScript
Method 1: Using gallery-dl tool
gallery-dl is a command-line tool that can download images and videos from various websites, including Instagram. It works by extracting the media URLs from the web pages and downloading them directly. You can use gallery-dl with JavaScript by executing it as a child process in your code.
To use gallery-dl with JavaScript, you need to do the following steps:
Install gallery-dl on your system by following the instructions on its .
Create a JavaScript file and import the child_process module from Node.js.
Define a function that takes an Instagram video URL as an argument and returns a promise that resolves with the downloaded file name.
The function should use the exec method from the child_process module to run the gallery-dl command with the given URL and the username and password of an Instagram account (without 2FA) as options.
The function should handle any errors or output from the exec method and resolve or reject the promise accordingly.
Call the function with an Instagram video URL and use then and catch methods to handle the promise result.
// Define the gallery-dl command with the URL and the Instagram credentials as options const command = `gallery-dl --username your_username --password your_password $url`; // Execute the command as a child process exec(command, (error, stdout, stderr) => // If there is an error, reject the promise with the error message if (error) reject(error.message); // If there is any output, parse it and extract the file name else if (stdout) const output = JSON.parse(stdout); const fileName = output[0].path; // Resolve the promise with the file name resolve(fileName); // If there is any error output, reject the promise with the error output else if (stderr) reject(stderr); ); ); // Call the function with an Instagram video URL downloadInstagramVideo(" // Handle the promise result .then((fileName) => // Log the file name to the console console.log(`Downloaded video: $fileName`); ) .catch((error) => // Log the error to the console console.error(`Error: $error`); ); ``` Method 2: Using Instagram Graph API
Instagram Graph API is an official API that allows developers to access and manage Instagram data, such as users, media, insights, and comments. You can use Instagram Graph API with JavaScript by making HTTP requests to its endpoints and handling the responses. To use Instagram Graph API with JavaScript, you need to do the following steps:
Create a Facebook developer account and register an app on its .
Add the Instagram Basic Display product to your app and configure its settings.
Generate an access token for your app by following the instructions on this .
Create a JavaScript file and import the axios module from Node.js or use the native fetch API in web browsers.
Define a function that takes an Instagram video ID as an argument and returns a promise that resolves with the video URL.
The function should use axios or fetch to make a GET request to the Instagram Graph API endpoint for media fields with the video ID and the access token as parameters.
The function should handle any errors or responses from the request and resolve or reject the promise accordingly.
Call the function with an Instagram video ID and use then and catch methods to handle the promise result.
Here is an example of the JavaScript code that uses web scraping techniques to get the video URL: ```javascript // Import the cheerio and request-promise modules from Node.js const cheerio = require("cheerio"); const rp = require("request-promise"); // Define a function that takes an Instagram video URL and returns a promise function getInstagramVideoURL(url) // Create a new promise object return new Promise((resolve, reject) => // Define the options for the GET request const options = uri: url, transform: (body) => // Transform the response body into a cheerio object return cheerio.load(body); , ; // Make the GET request using request-promise rp(options) .then(($) => // If the request is successful, find the video tag that contains the video source const videoTag = $("video"); // Extract the video source attribute from the video tag const videoSource = videoTag.attr("src"); // Resolve the promise with the video source resolve(videoSource); ) .catch((error) => // If there is an error, reject the promise with the error message reject(error.message); ); ); // Call the function with an Instagram video URL getInstagramVideoURL(" // Handle the promise result .then((videoURL) => // Log the video URL to the console console.log(`Video URL: $videoURL`); ) .catch((error) => // Log the error to the console console.error(`Error: $error`); ); ``` Conclusion
