Hey everyone!
So, I’ve been diving into how to scrap 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 can get tricky if you don’t know the right tools or practices.
I’ve been using `colly` for scraping—it’s super lightweight and easy to set up. Also, `goquery` is a lifesaver for parsing HTML. But, like, handling dynamic content (looking at you, JS-heavy sites) is where things get messy.
Anyone got tips on how to scrap data from web with golang efficiently? Like, how do you deal with rate limits or avoid getting blocked? Also, any other tools or libraries you swear by?
Oh, and if you’ve got any horror stories or “wish I knew this earlier” moments, spill the tea!
Cheers!
Hey! I’ve been working on how to scrap data from web with golang for a while now, and I totally feel your pain with dynamic content. One thing that saved me was using `chromedp`—it’s a Go package that lets you control Chrome via the DevTools Protocol. It’s a bit heavier than `colly`, but it handles JS-heavy sites like a champ.
For rate limits, I usually set random delays between requests and rotate user-agent strings. Also, check out `proxycrawl`—it’s a paid service, but it helps avoid getting blocked.
Oh, and one horror story: I once accidentally DDOS’d a small site because I forgot to add delays. Learned that lesson the hard way!
Yo! Scraping with Golang is a vibe, but yeah, dynamic content is a headache. I’ve been using `rod` lately—it’s like `chromedp` but simpler and faster for JS-heavy sites.
For avoiding blocks, I use a combo of proxies (I scrape free ones from sites like `free-proxy-list.net`) and random delays. Also, make sure to respect `robots.txt` unless you wanna get banned lol.
If you’re into learning, check out `scrapingbee.com`. They’ve got a ton of resources on how to scrap data from web with golang and other languages.
Hey there! I’ve been scraping with Golang for a while, and I agree—`colly` and `goquery` are solid choices. For dynamic content, I’d recommend `selenium` with a Go wrapper like `tebeka/selenium`. It’s slower but gets the job done.
For rate limits, I use a library called `gocron` to schedule my scrapers. It helps space out requests and avoid getting blocked. Also, rotating IPs with a VPN or proxy service helps a ton.
One tip: always cache your results locally. It saves time if you need to re-scrape or debug.
Hey! I’m also into how to scrap data from web with golang, and I’ve found `colly` to be a gem. For dynamic content, I use `puppeteer-go`—it’s a Go port of the Node.js library. It’s a bit of a learning curve, but it handles JS-heavy sites really well.
To avoid getting blocked, I use a mix of residential proxies (check out `oxylabs.io`) and random delays. Also, make sure to monitor your scraper’s behavior—sometimes it’s easy to miss when you’re sending too many requests.
One thing I wish I knew earlier: always log your errors. It makes debugging way easier.
Hey! I’ve been scraping with Golang for a bit, and I totally get the frustration with dynamic content. I’ve been using `agouti` for headless browser automation—it’s lightweight and works well for JS-heavy sites.
For rate limits, I use a combination of `time.Sleep()` with random intervals and rotating proxies. I scrape free proxies from `spys.one`, but you gotta filter out the bad ones.
Also, check out `scrapy.org`—it’s not Go, but their docs have some great tips on scraping best practices that apply to any language.
Hey! I’ve been diving into how to scrap data from web with golang too, and I’ve found `colly` to be super handy. For dynamic content, I use `headless chrome` with `chromedp`. It’s a bit slower, but it works like magic for JS-heavy sites.
To avoid getting blocked, I use a mix of rotating proxies (I use `luminati.io`) and random delays. Also, make sure to set a custom user-agent string—it helps a lot.
One thing I learned the hard way: always test your scraper on a small dataset first. It saves a lot of headaches later.
Hey! I’ve been working on how to scrap data from web with golang for a while, and I’ve found `colly` to be a lifesaver. For dynamic content, I use `go-rod`—it’s a newer library but super easy to use.
For rate limits, I use a combination of random delays and rotating proxies. I scrape free proxies from `proxy-list.download`, but you gotta be careful with the quality.
Also, check out `scrapingant.com`—they’ve got a great API for handling JS-heavy sites.
Wow, thanks for all the awesome tips, everyone! I’ve been experimenting with `chromedp` and `rod` based on your suggestions, and they’re definitely making a difference with JS-heavy sites.
I also set up random delays and started rotating proxies—thanks for the heads-up on `free-proxy-list.net` and `oxylabs.io`. I’ll check those out.
One quick follow-up: anyone have tips on handling CAPTCHAs? I’ve been running into them more often lately, and it’s a pain.
Cheers again for all the help!
