Installing NodeJS on Raspberry Pi

Before we begin installing NodeJS on the Raspberry Pi, we need to update and upgrade the packages to receive the latest updates.

sudo apt update
sudo apt upgrade

We can now proceed with installing NodeJS:

curl -fsSL https://deb.nodesource.com/setup_20.x | sudo bash -
sudo apt-get install -y nodejs

To confirm that we have now successfully installed NodeJS, we can run the following command:

node -v
npm -v

Now we need to install a module called pnpm which we will be using later on

sudo npm i pnpm -g

Uploading Bot Project

FileZilla is the easiest method to upload your bot files. However, we need to connect our Raspberry Pi first.

Firstly, we need to open Site Manager and create a New Site:

• Host = IP of your Raspberry Pi
• Port = 22
• Protocol = SFTP - SSH File Transfer Protocol
• Logon Type = Ask For Password (Personal preference)
• User = Username of your Raspberry Pi
• Password = Your Raspberry Pi SSH password

Once you have saved and successfully connected, you can now drag and drop your exported files to the Raspberry Pi!

Back to the SSH terminal, we need to find the folder. In my use case, it would be in /home/df/bmd-bot, so I type in cd /home/df/bmd-bot.

Before we begin to run the bot, we need to install modules in order for the Discord bot to function:

pnpm i

Finally, run the command node bot.js and now the bot is hosted on your Raspberry Pi. Yippie!

You can now close your FileZilla until you need it again in the future.

PM2 (Optional)

npm i pm2 -g

Navigate to your bot folder and enter the following command:

sudo pm2 start bot.js --name <app_name>

Example:

sudo pm2 start bot.js --name TheBestBotEver

You can go even further by configuring PM2 to restart your bot when files change, set a memory threshold for bot reload, and much more. For detailed instructions, visit https://pm2.keymetrics.io/docs/usage/pm2-doc-single-page

To check your bot's usage, enter: sudo pm2 monit.
