**Featured in [issue 327 of Golang Weekly](https://golangweekly.com/issues/327) 🎉**

go-reddit is a Go client library for accessing the Reddit API.

You can view Reddit's official API documentation [here](https://www.reddit.com/dev/api/).

## Install

To get a specific version from the list of [versions](https://github.com/vartanbeno/go-reddit/releases):

```sh
go get github.com/vartanbeno/go-reddit@vX.Y.Z
```

Or for the latest version:

```sh
go get github.com/vartanbeno/go-reddit
```

## Usage

Make sure to have a Reddit app with a valid client id and secret. [Here](https://github.com/reddit-archive/reddit/wiki/OAuth2-Quick-Start-Example#first-steps) is a quick guide on how to create an app and get credentials.

```go
package main

import "github.com/vartanbeno/go-reddit/reddit"

func main() {
    withCredentials := reddit.WithCredentials("id", "secret", "username", "password")
    client, _ := reddit.NewClient(withCredentials)
}
```

You can pass in a number of options to `NewClient` to further configure the client (see [reddit/reddit-options.go](reddit/reddit-options.go)). For example, to use a custom HTTP client:

```go
httpClient := &http.Client{Timeout: time.Second * 30}
client, _ := reddit.NewClient(withCredentials, reddit.WithHTTPClient(httpClient))
```

### Read-Only Mode

The global `DefaultClient` variable is a valid, read-only client with limited access to the Reddit API, much like a logged out user. You can initialize your own via `NewReadonlyClient`:

```go
client, _ := reddit.NewReadonlyClient()
```

## Examples

<details>
    <summary>Configure the client from environment variables.</summary>

```go
client, _ := reddit.NewClient(reddit.FromEnv)
```
</details>

<details>
    <summary>Submit a comment.</summary>

```go
comment, _, err := client.Comment.Submit(context.Background(), "t3_postid", "comment body")
if err != nil {
    return err
}
fmt.Printf("Comment permalink: %s\n", comment.Permalink)
```
</details>

<details>
    <summary>Upvote a post.</summary>

```go
_, err := client.Post.Upvote(context.Background(), "t3_postid")
if err != nil {
    return err
}
```
</details>

<details>
    <summary>Get r/golang's top 5 posts of all time.</summary>

```go
result, _, err := client.Subreddit.TopPosts(context.Background(), "golang", &reddit.ListPostOptions{
    ListOptions: reddit.ListOptions{
        Limit: 5,
    },
    Time: "all",
})
if err != nil {
    return err
}
fmt.Printf("Received %d posts.\n", len(result.Posts))
```
</details>

## Design

The package design is heavily inspired from [Google's GitHub API client](https://github.com/google/go-github) and [DigitalOcean's API client](https://github.com/digitalocean/godo).
