π JavaScript Step-by-stepExtract comments data from Facebook. Real code, real responses, real production patterns β paste it into your project and ship.
Learn how to scrape Facebook comments using JavaScript. This comprehensive guide will walk you through the entire process, from setup to implementation.
First, you'll need a ScrapeCreators API key to authenticate your requests.
Sign up at app.scrapecreators.com to get your free API key with 100 requests.
Make sure you have the following installed:
Axios is a promise-based HTTP client for Node.js
npm install axiosNow let's make a request to the Facebook API using JavaScript. Replace YOUR_API_KEY with your actual API key.
import axios from 'axios';
const API_KEY = 'YOUR_API_KEY';
async function scrape() {
try {
const response = await axios.get(`https://api.scrapecreators.com/v1/facebook/post/comments?url=https://www.facebook.com/reel/753347914167361&feedback_id=ZmVlZGJhY2s6MTQ0NzY1NjMyMzM4Mzg0OA==&cursor=MToxNzU3MTA2NzYyOgF1P1VkxpkA9Ds4...`, {
headers: {
'x-api-key': API_KEY,
'Content-Type': 'application/json'
}
});
console.log('Response:', response.data);
return response.data;
} catch (error) {
console.error('Error:', error.response?.data || error.message);
}
}
// Usage
scrape();This endpoint accepts the following parameters:
urlOptional(string)Facebook post URL (or reel URL)
Example: https://www.facebook.com/reel/753347914167361
feedback_idOptional(string)Using feedback_id (instead of url) will *really* speed up the request. You can get the feedback_id when you make a request to /v1/facebook/post.
Example: ZmVlZGJhY2s6MTQ0NzY1NjMyMzM4Mzg0OA==
cursorOptional(string)Cursor to get more comments. Get 'cursor' from previous response.
Example: MToxNzU3MTA2NzYyOgF1P1VkxpkA9Ds4...
Execute your script to test the API connection. You should see a JSON response with Facebook comments data.
β Success: You should receive a structured JSON response containing the requested data.
Here's an example of the JSON response you'll receive:

}Check that your response includes the expected fields:
success(boolean)credits_remaining(number)comments(object)cursor(string)has_next_page(boolean)Implement comprehensive error handling and retry logic for failed requests. Log errors properly for debugging.
Cache responses when possible to reduce API calls and improve performance. Consider data freshness requirements.
Never expose your API key in client-side code. Use environment variables and secure key management practices.
When scraping multiple comments, consider batching requests to maximize throughput while staying within rate limits.
Use asynchronous processing in JavaScript to handle multiple requests concurrently and improve overall performance.
Analyze Facebook comments to understand market trends, competitor analysis, and audience insights.
Track performance metrics, engagement rates, and content trends across Facebook comments.
Identify potential customers and business opportunities throughFacebook data analysis.
Check your API key is correct and properly formatted in the x-api-key header.
You ran out of credits and need to buy more.
The resource might not exist or be private.
Temporary server issue. Implement retry logic with exponential backoff.
ScrapeCreators offers 100 free API calls to get started. After that, pricing starts at $10 for 5k requests with volume discounts available.
Scraping publicly available data is fair game, and we only collect public data. So anything that you can see in an incognito browser is what we collect.
There is no rate limit! So you can scrape as fast as you want!
All API responses are returned in JSON format, making it easy to integrate with any programming language or application.
Yes! This tutorial focuses on core JavaScript HTTP concepts that work with any framework. The API calls remain the same regardless of your specific JavaScript setup.
For large datasets, implement pagination, use streaming responses where available, and consider storing data in a database for efficient querying.
