I would like to recommend a website of mine that I made during my Golang learning.
My website http://techdaily.info is for learning golang language.
Besides crawling dev.to, I also crawl some other websites like freecodecamp.com, medium.com, hashnode.com, logrocket.com, infoq.com
So I built a website that specializes in crawling other sites
some technology that i used.

• Golang
• Colly
• Nginx
• Service
• Docker
• Mysql
• Run action deploy to server
• Cronjob daily crawl

Folder vendor

docker-compose exec crawl go mod vendor

Run Crawl

docker-compose exec crawl go run cmd/main.go

Use air autoload

docker-compose exec crawl air -c .air.conf

Deploy

Run file makefile build project into folder bin

make copy_template build_app_web build_app_crawl
