Setting up a Puppeteer screenshot API

Objective: I needed to setup an API end-point that, when passed a URL would take a screenshot of the website. This guide covers the setup of a Node.js application using Puppeteer, which will act as an API for capturing screenshots.

Easily capture website screenshots by setting up a Node.js API using Puppeteer. This quick guide takes you through the setup, from installing dependencies to writing the endpoint.

For the sake of conciseness, I am going to skip some pre-requisites, and some steps. For the full article, go to here.

const express = require('express');
const puppeteer = require('puppeteer');
const app = express();
const port = 3000;

app.get('/screenshot', async (req, res) => {
    const { url } = req.query;
    if (!url) return res.status(400).send('Please provide a URL');
    
    try {
        const browser = await puppeteer.launch({ args: ['--no-sandbox', '--disable-setuid-sandbox'] });
        const page = await browser.newPage();
        await page.goto(url, { waitUntil: 'networkidle2' });
        const screenshot = await page.screenshot({ fullPage: true });
        await browser.close();
        res.setHeader('Content-Type', 'image/png');
        res.send(screenshot);
    } catch (error) {
        res.status(500).send('Error capturing screenshot');
    }
});

app.listen(port, () => console.log(`API running on http://localhost:${port}`));
