I’m new to Puppeteer and struggling to get it working. I’ve installed npm, node, and puppeteer using apt-get and npm. The docs mention creating a Browser instance, but I’m not sure what that means.
I’ve got a simple script to take a screenshot:
const puppeteer = require('puppeteer');
(async () => {
const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.goto('http://example.com');
await page.screenshot({path: 'test.png'});
await browser.close();
})();
I’ve tried running it with node script.js, but nothing happens. No errors, no screenshot. I also tried node install.js and running the code directly in the terminal, but no luck.
What am I missing? How do I actually run this Puppeteer code and get it to work? Any help would be great!
hey man, i had similar issues. check you’re in the right folder and that puppeteer is installed. also, add a console.log after the screenshot line to see if it reaches that point. sometimes it’s just slow. good luck!
It appears that your Puppeteer script is mostly set up correctly. One thing to verify is that you are running the script from the proper directory where your project and its node modules reside. Also, ensure that Puppeteer is listed in your project’s package.json. From my experience, inserting console.log statements at key points can help identify where execution might be stalling. For instance, adding logs before and after launching the browser can be beneficial. Additionally, running Puppeteer in non-headless mode by specifying {headless: false} in the launch options can offer more visual feedback during debugging. These adjustments may help uncover any underlying issues with the execution process.
I’ve been in your shoes, and I know how frustrating it can be when things don’t work as expected. One thing that helped me was adding error handling to my Puppeteer scripts. Try wrapping your code in a try-catch block:
(async () => {
try {
const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.goto('http://example.com');
await page.screenshot({path: 'test.png'});
await browser.close();
console.log('Screenshot saved successfully');
} catch (error) {
console.error('An error occurred:', error);
}
})();
This way, if there’s an issue, you’ll see it in the console. Also, make sure you’re running the script from the correct directory and that you’ve installed Puppeteer locally in your project folder, not just globally. If you’re still having trouble, try running Puppeteer with {headless: false} to see what’s happening in real-time. Hope this helps!
