# LastFMDownloader
|
|
Downloader from Last.fm scrobble to MP3 file. Uploads to Nextcloud because it can.
|
|
|
|
## Setup
|
|
|
|
### Installation & running
|
|
|
|
To install LastFMDownloader, you need to run `git clone` in the path you desire. The program does not require root privileges, so your user's home folder will suffice.
|
|
|
|
After you have cloned the application, run `./update.sh` in order to pull the latest version and install the required npm packages. Now, LastFMDownloader can be set up.
|
|
|
|
### .env file
|
|
Here's `.env.example` in its entirety. We will go through each section, filling out each variable as we go.
|
|
```conf
|
|
# Last.fm
|
|
|
|
LASTFM_INSTANCE= # ws.audioscrobbler.com
|
|
|
|
LASTFM_USERNAME= # meowcatheorange
|
|
LASTFM_API_KEY= # cccccccccccccccccc...
|
|
|
|
# Cobalt
|
|
|
|
COBALT_INSTANCE= # co.wuk.sh
|
|
|
|
# Nextcloud
|
|
|
|
NEXTCLOUD_INSTANCE= # next.abtmtr.link
|
|
|
|
NEXTCLOUD_USERNAME= # meowcatheorange
|
|
NEXTCLOUD_PASSWORD= # ccccc-ccccc-ccccc-ccccc-ccccc
|
|
|
|
NEXTCLOUD_FOLDER= # /Music/LastFMDownloader/
|
|
|
|
# Notifications
|
|
|
|
NOTIFICATION_SERVER_PORT= # 80
|
|
NOTIFICATION_SERVER_PASSWORD= # password123
|
|
|
|
NOTIFICATION_CLIENT_INSTANCE= # secret.abtmtr.link
|
|
NOTIFICATION_CLIENT_PORT= # 80
|
|
NOTIFICATION_CLIENT_PROTOCOL= # https
|
|
```
|
|
|
|
#### LASTFM_INSTANCE
|
|
|
|
You can simply replace the comment with `ws.audioscrobbler.com`.
|
|
|
|
#### LASTFM_USERNAME
|
|
|
|
If you have a Last.fm account (you really should), this is where you will put the username of your account so it knows who to get scrobbles from.
|
|
|
|
#### LASTFM_API_KEY
|
|
|
|
Go to https://www.last.fm/api, and click on **Get an API account** under **Getting Started**. Fill out the form. All you need is a contact email and an application name.
|
|
|
|
After that, you will be sent to a page with your new API account info on it. Replace the comment with the **API key**.
|
|
|
|
#### COBALT_INSTANCE
|
|
|
|
If you run an instance of the Cobalt API (the tool that LastFMDownloader uses to download YouTube videos), you can input its URL here. Otherwise, replace the comment with an instance of your choosing, or `co.wuk.sh`.
|
|
|
|
#### NEXTCLOUD_INSTANCE
|
|
|
|
If you use Nextcloud (or any other WebDAV-compatible software), you can put its domain here.
|
|
|
|
#### NEXTCLOUD_USERNAME
|
|
|
|
The username of your Nextcloud / WebDAV account.
|
|
|
|
#### NEXTCLOUD_PASSWORD
|
|
|
|
The HTTP Basic password of your Nextcloud / WebDAV account. If you use Nextcloud specifically, you most likely have access to App Passwords within **[profile picture]** > **Personal settings** > **Security** > **Devices & sessions**. Make sure to use these! Put the App Password or account password here.
|
|
|
|
#### NEXTCLOUD_FOLDER
|
|
|
|
The folder that LastFMDownloader will use to store its music, if you're categorically inclined. Otherwise, you can use `/`, `/LastFMDownloader/`, or `/Music/LastFMDownloader/`.
|
|
|
|
### Run on Linux
|
|
|
|
This setup guide will mainly focus on Linux.
|
|
|
|
To run LastFMDownloader properly, you can set it up on a cronjob.
|
|
|
|
Install the `crontab` command if you haven't already, then run `crontab -e`.
|
|
|
|
Edit the crontab to contain this line (make sure to change it accordingly):
|
|
|
|
```
|
|
*/1 * * * * cd <LastFMDownloader path> && <Path to Node.js binary ("which node")> index.js
|
|
```
|
|
This will run LastFMDownloader's main application every single minute.
|
|
|
|
### Delivering notifications
|
|
|
|
If you want to know when LastFMDownloader is downloading a song, you can run the notification daemon on both your server computer and client computer.
|
|
|
|
#### .env file
|
|
|
|
Here's the variables we left out when setting up `.env.example` for the first time. We're going to fill them out right now.
|
|
|
|
```conf
|
|
# Notifications
|
|
|
|
NOTIFICATION_SERVER_PORT= # 80
|
|
NOTIFICATION_SERVER_PASSWORD= # password123
|
|
|
|
NOTIFICATION_CLIENT_INSTANCE= # secret.abtmtr.link
|
|
NOTIFICATION_CLIENT_PORT= # 80
|
|
NOTIFICATION_CLIENT_PROTOCOL= # https
|
|
```
|
|
|
|
##### NOTIFICATION_SERVER_PORT
|
|
|
|
This will be the port that your notification server runs on. Set this to any port but 80 or 443 - you will need to use a reverse proxy like **nginx** or **Apache** in order to properly run this application.
|
|
|
|
##### NOTIFICATION_SERVER_PASSWORD
|
|
|
|
This will be the password that LastFMDownloader will use to communicate messages to the notification server. Set it to something secure, or random. You won't have to type this in, so it can be as long as you want.
|
|
|
|
#### Systemd
|
|
|
|
Run your text editor of choice with the file `/etc/systemd/system/lfmdns.service`.
|
|
|
|
Edit the file to this block of configuration code (make sure to change it accordingly):
|
|
|
|
```conf
|
|
[Unit]
|
|
Description=LastFMDownloader Notification Server
|
|
|
|
[Service]
|
|
ExecStart=<Path to Node.js binary ("which node")> <LastFMDownloader path>/notification-server.js
|
|
User=<user>
|
|
RestartSec=1
|
|
Restart=always
|
|
Environment=PATH=<LastFMDownloader path>
|
|
WorkingDirectory=<LastFMDownloader path>
|
|
|
|
[Install]
|
|
WantedBy=multi-user.target
|
|
```
|
|
|
|
Save the file, then run this command as root:
|
|
|
|
```
|
|
systemctl daemon-reload
|
|
```
|
|
|
|
And then, once again as root:
|
|
|
|
```
|
|
systemctl enable lfmdns --now
|
|
```
|
|
|
|
The notification server should now be running. If you run
|
|
|
|
```
|
|
systemctl status lfmdns
|
|
```
|
|
|
|
you should be able to see the message "A client connected!" pop up on the minute, every minute. This is LastFMDownloader connecting to the notification server.
|
|
|
|
### Recieving notifications
|
|
|
|
To recieve LastFMDownloader notifications, you have to install LastFMDownloader somewhere on your host computer. Feel free to follow the directions in [Installation & running](#installation--running).
|
|
|
|
#### .env file
|
|
|
|
Here's the variables we left out when setting up `.env.example` in **Delivering notifications**. We're going to fill them out right now.
|
|
|
|
```conf
|
|
NOTIFICATION_CLIENT_INSTANCE= # secret.abtmtr.link
|
|
NOTIFICATION_CLIENT_PORT= # 80
|
|
NOTIFICATION_CLIENT_PROTOCOL= # https
|
|
```
|
|
|
|
##### NOTIFICATION_CLIENT_INSTANCE
|
|
|
|
The domain that your notification server is running on. This can either be `localhost`, `[ip address of the machine running LastFMDownloader]`, or `[web domain]`.
|
|
|
|
##### NOTIFICATION_CLIENT_PORT
|
|
|
|
The port that your notification server occupies. Can either be `80`, `443` or the same as what you set `NOTIFICATION_SERVER_PORT` to on your server.
|
|
|
|
##### NOTIFICATION_CLIENT_PROTOCOL
|
|
|
|
The protocol that your notification server uses. If `NOTIFICATION_CLIENT_PORT` is **443**, this has to be `https`. If it is **80**, it can be either `https` or `http`. Otherwise, if it is **neither**, it has to be `http`.
|
|
|
|
#### Script
|
|
|
|
Then, all you need to do is create a script on your computer that will run for as long as you are logged in.
|
|
|
|
On Linux, the script (`lfmdnc.sh`) should look like this:
|
|
|
|
```
|
|
#!/bin/bash
|
|
while true
|
|
do
|
|
cd <LastFMDownloader client path> && node notification-client.js
|
|
done
|
|
```
|
|
|
|
Running this script should notify you when you are connected to the server. If it sends a notification saying so, congratulations! You have successfully set up LastFMDownloader. |
