# GoHN — Hacker News API Wrapper for Go
GoHN is a wrapper for the [Hacker News API](https://github.com/HackerNews/API) for Go, inspired by the excellent [go-github](https://github.com/google/go-github) library.
It facilitates the use of the API by providing a simple interface to the API endpoints.
## Features 🚀
- Get the top/new/best/ask/show/job stories
- Retrieve all comments (with metadata) for a story using goroutines to speed up the process
- Retrieve the comments ordered as they appear in the story on the website
- Apply filters to retrieved items (stories, comments)
- Can be used with a custom http.Client instance (to use a proxy, for example)
## Usage 💻
Refer to the [GoDoc](https://pkg.go.dev/github.com/alexferrari88/gohn/pkg/gohn) for the full API reference.
### Example
Refer to [example/main.go](example/main.go) for a full example on how to retrieve the top stories' IDs and the all the comments for the first one.
```go
// Instantiate a new client to retrieve data from the Hacker News API
hn, _ := gohn.NewClient(nil)
// Use background context
ctx := context.Background()
// Get the top 500 stories' IDs
topStoriesIds, _ := hn.Stories.GetTopIDs(ctx)
var story *gohn.Item
// Retrieve the details of the first one
if len(topStoriesIds) > 0 && topStoriesIds[0] != nil {
story, _ = hn.Items.Get(ctx, *topStoriesIds[0])
}
if story == nil {
panic("No story found")
}
// Print the story's title
fmt.Println("Title:", *story.Title)
// Print the story's author
fmt.Println("Author:", *story.By)
// Print the story's score
fmt.Println("Score:", *story.Score)
// Print the story's URL
fmt.Println("URL:", *story.URL)
fmt.Println()
fmt.Println()
if story.Kids == nil {
fmt.Println("No comments found")
return
}
// Retrieve all the comments for that story
// UnescapeHTML is applied to each retrieved item to unescape HTML characters
commentsMap, err := hn.Items.FetchAllKids(ctx, story, processors.UnescapeHTML())
if err != nil {
panic(err)
}
if len(commentsMap) == 0 {
fmt.Println("No comments found")
return
}
fmt.Printf("Comments found: %d\n", len(commentsMap))
fmt.Println()
// Create a Story struct to hold the story and its comments
storyWithComments := gohn.Story{
Parent: story,
CommentsByIdMap: commentsMap,
}
// Calculate the position of each comment in the story
storyWithComments.SetCommentsPosition()
// Get an ordered list of comments' IDs (ordered by position)
orderedIDs, err := storyWithComments.GetOrderedCommentsIDs()
if err != nil {
panic(err)
}
// Print the comments
for _, id := range orderedIDs {
comment := commentsMap[id]
if comment.Text != nil {
fmt.Println(*comment.Text)
fmt.Println()
}
}
```
## Semantic Versioning 🥚
As this library is not yet in version 1.0.0, the API may have breaking changes between minor versions.
