## Prerequisite In order to follow this tutorial you will need to have golang installed on your machine ## Project ### 1. Finding rss feed We're gonna use this rss feed from this cool [developers tshirt](https://www.devshirt.club/) shop. They have rss of their newest t-shirt releases. You can find it [here](https://www.devshirt.club/developer-shirt/rss.xml) ### 2. Creating a new project 1.) In your `$GOPATH` create a new project ```mkdir rss_feed``` 2.) navigate to directory and init mod ```cd rss_feed && go mod init``` 3.) install rss reader dependency ``` go get github.com/mmcdole/gofeed``` ### 3. Reading the rss feed Reading the rss feed is super simple with mmcdole's library our full main: ``` package main import ( "log" "github.com/mmcdole/gofeed" ) var FeedUrl = "https://www.devshirt.club/developer-shirt/rss.xml" func main() { fp := gofeed.NewParser() fp.UserAgent = "MyCustomAgent 1.0" feed, _ := fp.ParseURL(FeedUrl) log.Printf("read the feed %#v", feed) } ``` ### 4. Creating html template Here we are gonna use golangs built in template, what it will expect is for us to pass a slice of articles, and in return it will generate us a simple html page. ``` type Article struct { Title string Description string ImageTitle string ImageUrl string Link string } var siteTemplate string = `

` ``` ### 5. Tying it all together We are gonna load our feed, based on that iterate and create our slice of articles and simply output to console our generated html ``` package main import ( "log" "os" "text/template" "github.com/mmcdole/gofeed" ) var FeedUrl = "https://www.devshirt.club/developer-shirt/rss.xml" type Article struct { Title string Description string ImageTitle string ImageUrl string Link string } var siteTemplate string = `

` func main() { fp := gofeed.NewParser() fp.UserAgent = "MyCustomAgent 1.0" feed, err := fp.ParseURL(FeedUrl) if err != nil { log.Fatal(err) } var articles []Article for _, item := range feed.Items { article := Article{ Title: item.Title, Description: item.Description, Link: item.Link, ImageUrl: item.Extensions["media"]["content"][0].Attrs["url"], } articles = append(articles, article) } tmpl, err := template.New("site").Parse(siteTemplate) if err != nil { log.Fatal(err) } err = tmpl.Execute(os.Stdout, articles) if err != nil { log.Fatal(err) } } ```
