yt-vid-discord-announcer

A go project created to let Kirei's community know about a new youtube video (and shorts). I've done this project as hobby so I'd get to know golang a little bit more with the goal to use it in my profession. Go checkout Kirei's youtube channel

Getting started

Clone this repo on your host of choice:

git clone https://github.com/RoMinjun/yt-vid-discord-announcer.git && cd yt-vid-discord-announcer

Adding thje .env file

Create the .env file with your selected language

Shell

touch .env

PowerShell

New-Item -Name .env -ItemType File

Make sure you populate the .env file with the following using your favorite editor (must be vi):

Tip

I'd recommend using a domain that's publicly acessible so the callback will work when you're hosting it on docker, if not, localhost will do the trick.

CLIENT_ID=<google-oauth-client-id>
CLIENT_SECRET=<google-oauth-client-secret>
CHANNEL_ID=<yt_channel_id>
REDIRECT_URL=http://localhost:8080/callback 
DISCORD_WEBHOOK_URL=<discord-webhook>

Using docker

building docker-compose (when using docker)

After you've populated the .env file in the root directory of the project, you can start the build:

docker compose up -d --build

and check the logging if desired to check whether the container is actually running or not:

docker compose logs -f

Without docker

Important

Recommended to use docker, but if you want it to work without docker add an absolute path to the .env

Example without docker in main.go:

// Get the absolute path to the .env file
// Adjust the path as necessary based on your directory structure
envPath, err := filepath.Abs("../../.env")
if err != nil {
  log.Fatalf("Error getting absolute path to .env file: %v", err)
}

// Log the absolute path to ensure it is correct
log.Printf("Loading .env file from: %s", envPath)

// Load the .env file
err = godotenv.Load(envPath)
err := godotenv.Load()
if err != nil {
  log.Fatalf("Error loading .env file: %v", err)
}

Start checking for videos

To initially automate the video checking process, you need to login with your google account to your project.

Visit your host + port (http://localhost:8080 .e.g.) and login with your google account and consent to the project you've created for your google oauth configuration by clicking on Advanced and go to localhost (unsafe) and continue. If you've done all of that, you'll be redirected to the REDIRECT_URL set in the .env file with the message Authorization successful, you can close this tab.

Now every 15 minutes the project will check for a new youtube video for the channel specified in the .env's CHANNEL_ID. I wouldn't recommend decreasing the check time since I'm currently reaching 9.9/10k with 15 minutes, the sweet spot.

Unfortunately the oauth tokens expire after an hour, hence i've made a token refresher in the project. Each 55th minute it will use the refresh token to retrieve a new oauth-token and so on. Example from logging:

app-1  | 2024/08/15 19:20:51 Refreshed token: Access Token: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
app-1  | 2024/08/15 19:20:51 Token refreshed successfully
