Looking to Learn: How to Scrape Data from Web with Golang – Any Tips or Best Practices?

Hey everyone! 👋

So, I’ve been diving into how to scrape data from web with Golang lately, and man, it’s been a mix of fun and frustration. Golang’s simplicity is awesome, but web scraping? Not always straightforward.

I’ve tried a couple of libraries like Colly and GoQuery, and they’re pretty solid, but I’m still figuring out the best way to handle dynamic content (looking at you, JavaScript-heavy sites). Anyone got tips on how to scrape data from web with Golang when the site’s throwing AJAX at you?

Also, what’s the deal with rate-limiting? I don’t wanna get blocked, but I also don’t wanna crawl at a snail’s pace.

Anyhoo, if y’all have some best practices or favorite tools for how to scrape data from web with Golang, hit me up! Would love to hear your thoughts.

Cheers! 🍻
Hey! I feel you on the dynamic content struggle. For JavaScript-heavy sites, I’ve had some luck using headless browsers like Chromedp or Playwright with Golang. They let you interact with the page as if you’re a real user, so AJAX isn’t a problem.

For rate-limiting, I usually set a delay between requests (like 2-3 seconds) and rotate user-agent strings. It’s not foolproof, but it helps avoid getting blocked.

If you’re still figuring out how to scrape data from web with Golang, check out Scrapy (Python) for inspiration—it’s not Golang, but their approach to handling rate limits is solid.

Good luck!
Yo! Golang + web scraping is a vibe once you get the hang of it. For dynamic content, I’d recommend Selenium with a Golang wrapper. It’s a bit heavy, but it works like a charm for JS-heavy sites.

Rate-limiting is tricky, but I’ve found that using proxies (like Bright Data or ScraperAPI) helps a ton. They handle the blocking stuff for you, so you can focus on the scraping part.

Also, don’t forget to check the site’s `robots.txt` file before you start. Some sites are cool with scraping, others… not so much.
Hey there! I’ve been down the rabbit hole of how to scrape data from web with Golang too. For dynamic content, Colly + Chromedp is my go-to combo. Colly for the static stuff, and Chromedp for the JS-heavy parts.

Rate-limiting is a pain, but I’ve found that adding random delays and using a pool of IPs (via proxies) keeps me under the radar.

Also, if you’re scraping a lot, consider caching the data locally. It saves time and reduces the number of requests you need to make.
Dynamic content is the worst, right? I’ve been using GoQuery for static pages and Rod (a headless browser lib for Golang) for the JS stuff. Rod’s pretty lightweight compared to Selenium, and it gets the job done.

For rate-limiting, I usually start with a 1-second delay and adjust based on how the site reacts. If I get blocked, I switch to rotating proxies.

Oh, and don’t forget to check out Beautiful Soup (Python) for ideas—it’s not Golang, but their techniques are gold.
Hey! I’ve been scraping with Golang for a while now, and here’s my two cents:

For dynamic content, Chromedp is a lifesaver. It’s a bit slower than Colly, but it handles JS like a pro.

Rate-limiting is all about balance. I usually set a delay of 1-2 seconds and use a proxy service like Oxylabs to avoid getting blocked.

Also, if you’re scraping a lot, consider using a database to store your results. It makes things way easier to manage.
Wow, thanks for all the awesome tips, everyone! I’ve been playing around with Chromedp based on your suggestions, and it’s been a game-changer for handling dynamic content. Still getting the hang of it, but it’s way better than what I was doing before.

I also tried adding random delays for rate-limiting, and it seems to be working so far. Haven’t been blocked yet, so fingers crossed!

Quick question though—anyone have experience with Rod vs. Chromedp? I’m curious which one’s faster for large-scale scraping.

Thanks again, y’all! This thread has been super helpful. 🍻
Dynamic content is a headache, but Playwright with Golang has been a game-changer for me. It’s super easy to set up and handles JS-heavy sites like a champ.

For rate-limiting, I’ve found that adding random delays and using a proxy service like Smartproxy works wonders.

Also, if you’re new to how to scrape data from web with Golang, I’d recommend starting with Colly. It’s beginner-friendly and has great docs.
Hey! I’ve been using GoQuery for static pages and Rod for dynamic content. Rod’s a bit tricky to set up, but once you get it working, it’s amazing.

For rate-limiting, I usually start with a 2-second delay and adjust based on the site’s response. If I get blocked, I switch to rotating proxies.

Also, don’t forget to check out Scrapy (Python) for inspiration. It’s not Golang, but their approach to scraping is top-notch.
Yo! Golang + web scraping is a match made in heaven once you figure it out. For dynamic content, I’d recommend Chromedp. It’s a bit slower than Colly, but it handles JS-heavy sites like a pro.

Rate-limiting is tricky, but I’ve found that using a proxy service like Luminati helps a ton. They handle the blocking stuff for you, so you can focus on the scraping part.

Also, if you’re scraping a lot, consider caching the data locally. It saves time and reduces the number of requests you need to make.
