Discord

A small go library to post messages to a Discord channel using Webhooks.

Setup

You must first configure a Webhook on a Discord server before you can use this package. Instructions can be found on Discord's support website.

Usage

You must first configure the Webhook URL that will be used

discord.WebhookURL = "https://discord.com/api/webhooks/.../..."

Then you can either send a simple text message or a more complex message

Simple Text Message

discord.Say("Hello, world!")

Complex Message

discord.Post(discord.PostOptions{
	Content: "Hello, world!",
	Embeds: []discord.Embed{
		{
			Author: discord.Author{
				Name: "ecnepsnai",
				URL:  "https://github.com/ecnepsnai",
			},
			Title:       "Amazing!",
			Description: "This is a cool embed",
		},
	},
})

File Attachment

Restrictions with Discords Webhook API only supports 1 file upload at 8MiB or less.

var f *io.Reader // Pretend we've opened a file
content := discord.PostOptions{
	Content: "Hello, world!",
}
fileOptions := discord.FileOptions{
	FileName: "my_hot_mixtape.mp3",
	Reader:   f,
}
discord.UploadFile(content, fileOptions)

Functions

func Post

func Post(content PostOptions) error

Post will post a message to the channel for which the webhook is configured. Unlike `discord.Say()`, Post gives you full control over the message.

Example

package main

import (
	"github.com/ecnepsnai/discord"
)

func main() {
	discord.WebhookURL = "https://discord.com/api/webhooks/.../..."
	discord.Post(discord.PostOptions{
		Content: "Hello, world!",
		Embeds: []discord.Embed{
			{
				Color: 16777215,
				Author: &discord.Author{
					Name: "ecnepsnai",
					URL:  "https://github.com/ecnepsnai",
				},
				Title:       "Amazing!",
				Description: "This is a cool embed",
			},
		},
	})
}

func Say

func Say(message string) error

Say sends the provided message to the channel for which the webhook is configured. If WebhookURL is not set, this does nothing.

Example

package main

import (
	"github.com/ecnepsnai/discord"
)

func main() {
	discord.WebhookURL = "https://discord.com/api/webhooks/.../..."
	discord.Say("Hello, world!")
}

func UploadFile

func UploadFile(content PostOptions, file FileOptions) error

UploadFile will post a message to the channel for which the webhook is configured and attach the specified file to your message. Rich embeds are not supported and will be ignored if any are specified.

Example

package main

import (
	"io"

	"github.com/ecnepsnai/discord"
)

func main() {
	discord.WebhookURL = "https://discord.com/api/webhooks/.../..."
	var f io.Reader // Pretend we've opened a file
	content := discord.PostOptions{
		Content: "Hello, world!",
	}
	fileOptions := discord.FileOptions{
		FileName: "my_hot_mixtape.mp3",
		Reader:   f,
	}
	discord.UploadFile(content, fileOptions)
}
