# ClassicFM Discord Bot
|
|
|
|
|
|
|
|
A bot that constantly streams ClassicFM, a British classical music radio station, into a Discord voice channel of the user's choosing.
|
|
|
|
This bot uses an **m3u8** stream as its source and joins a channel of the user's choosing until it is forcefully disconnected. This can be helpful if you want to just make a voice channel for peacefully listening to classical music, and **it can be used with any mp3 or m3u8 stream**.
|
|
|
|
Like any other bot, this requires that you make an application (bot) in the [Discord Developer Portal](https://discord.com/developers/applications).
|
|
|
|
This mini project quite literally would not have been possible without [@ChrisChrome](https://github.com/ChrisChrome), who basically made the whole fucking thing work and showed me the limitations of both Discord bots and JavaScript as a whole.
|
|
|
|
## How To Use
|
|
First, clone this GitHub repository, open it, and install dependencies.
|
|
```
|
|
git clone https://github.com/szeremeta1/classicfm-discord-bot.git
|
|
cd classicfm-discord-bot
|
|
npm i
|
|
```
|
|
|
|
Next, add your bot token you obtained from the Discord Developer Portal.
|
|
```
|
|
cd src
|
|
sudo nano config.json
|
|
```
|
|
|
|
Finally, `cd` back into `classicfm-discord-bot` and start the bot.
|
|
```
|
|
cd
|
|
cd classicfm-discord-bot
|
|
pm2 start ./src/bot.js
|
|
```
|
|
|
|
## Troubleshooting
|
|
### Cannot Play Audio: No Valid Encryption Package is Installed
|
|
If you receive an error like this:
|
|
```
|
|
Error: Cannot play audio as no valid encryption package is installed.
|
|
- Install sodium, libsodium-wrappers, or tweetnacl.
|
|
- Use the generateDependencyReport() function for more information.

```
|
|
|
|
Then `sodium` is being a bitch. Despite saying it needs to be installed, it is already in `node_modules`. This can be fixed by completely deleting `sodium` from `node_modules` and reinstalling it.
|
|
```
|
|
cd classicfm-discord-bot
|
|
cd node_modules
|
|
sudo rm -rf sodium
|
|
cd
|
|
cd classicfm-discord-bot
|
|
npm i sodium
|
|
```
|
|
|
|
This may take a while, as it has for me. Just wait patiently, even if it appears to be frozen. After it's done, `cd` back into `classicfm-discord-bot` and start the bot.
|
|
```
|
|
cd classicfm-discord-bot
|
|
pm2 start ./src/bot.js
|
|
```
|
|
|
|
### Error: Cannot find module 'node-opus' / 'opusscript'
|
|
Similarly to the `sodium` error, in this case, `opusscript` is being a bitch. The error you may receive looks like this:
|
|
```
|
|
Error: Cannot find module 'node-opus'
|

```
|
|
|
|
To solve this error, simply `cd` into `classicfm-discord-bot` and reinstall it. For this module, I didn't need to `rm -rf` it from `node-modules`, but your situation may be different.
|
|
```
|
|
cd classicfm-discord-bot
|
|
npm i opusscript
|
|
```
|
|
|
|
This shouldn't take long. When it is complete, attempt to start the bot again with `pm2 start ./src/bot.js` or `node ./src/bot.js` while in the `classicfm-discord-bot` folder.
