"Hey folks!
I’ve been trying to figure out *how to scrap data from web with Golang*, but I’m kinda stuck.
Any tips or best practices? Like, what libraries do y’all recommend? I’ve seen `colly` thrown around a lot—is it the go-to?
Also, how do you avoid getting blocked? Proxies? Delays? Or is there some sneaky trick I’m missing?
And uh… is there a way to make it *efficient*? My current script feels slower than a dial-up connection lol.
Would love any advice—even if it’s just “don’t do it, use Python instead” 😅
Thanks in advance!"
Hey! Colly is definitely a solid choice for how to scrap data from web with Golang. It’s easy to use and handles a lot of the heavy lifting for you.
For avoiding blocks, yeah, proxies help—check out Bright Data or ScraperAPI. Also, randomize your delays between requests (like 2-5 seconds).
If speed’s an issue, try goroutines! Colly + goroutines can speed things up big time. Just don’t go too wild or you’ll get banned faster than you can say "Golang web scraping."
Lol @ the dial-up comment. Been there.
Colly’s great, but if you wanna go bare-metal, net/http + goquery works too. Less magic, more control.
For blocking: rotate user-agents, use residential proxies, and mimic human behavior (like random clicks). Tools like ScrapingBee handle this for you if you don’t wanna DIY.
Efficiency? Benchmark your code. Maybe it’s not Golang—could be the site’s anti-bot measures throttling you.
Honestly, for how to scrap data from web with Golang, Colly’s the way to go. It’s got built-in rate limiting, which helps avoid bans.
Proxies are a must if you’re scraping at scale. I use Luminati, but it’s pricey. Free proxies? Nah, they’re trash.
Speed tip: Cache responses locally so you’re not re-fetching the same data. Also, avoid parsing unnecessary stuff—keep your selectors tight.
Python fan here, but Golang’s not bad for scraping! Colly’s good, but if you need something lighter, check out goquery.
Blocking? Yeah, proxies + delays. But also, don’t ignore cookies. Some sites track sessions.
Efficiency: Profile your code. Maybe it’s not the scraping—could be your DOM parsing slowing things down.
Colly’s cool, but if you’re scraping JS-heavy sites, you might need a headless browser like chromedp. Golang’s not the best for this, but it works.
Avoiding blocks: Use rotating IPs and set realistic delays. Tools like ProxyMesh can help.
Speed: Goroutines, but don’t overload the server. Be polite—or they’ll ban you forever.
Wow, thanks for all the tips! Colly + goroutines seems like the move—gonna try that today.
Quick follow-up: Anyone got a good tutorial for setting up proxies with Colly? The docs are a bit sparse.
Also, lol @ "be polite or get banned." Noted. 😅
For how to scrap data from web with Golang, I’d say start with Colly. It’s beginner-friendly and well-documented.
Proxies? Yeah, but also:
- Respect robots.txt
- Don’t hammer the server (randomize delays)
Efficiency: If your script’s slow, check if you’re reusing connections (enable HTTP keep-alive).
Golang’s decent for scraping, but it’s not as smooth as Python. Colly’s your best bet, though.
Blocking: Use proxies (I like Smartproxy) and mimic human behavior. Some sites detect headless browsers, so watch out.
Speed: Try concurrent requests with goroutines, but keep it reasonable. Too many = instant ban.
Colly’s the go-to for how to scrap data from web with Golang. It’s fast and easy.
Avoiding blocks: Rotate headers, use proxies, and add random delays. Free proxies suck—invest in good ones.
Efficiency: If it’s slow, check your selectors. Maybe you’re parsing too much junk.
