# Installation

# Installing Node.js

# Windows

Head over to the Node.js websiteopen in new window and download the latest version.

# macOS

If you're developing on macOS, you have a few options. You can go to the Node.js websiteopen in new window, download the latest version, double click the package installer, and follow the instructions. Or you can use a package manager like Homebrewopen in new window with the command brew install node.

# Installing on Linux

If you're developing on Linux, you may consult this pageopen in new window to determine how you should install Node. On that note, there's a possibility that you may already have Node (e.g., if you're using a VPS). You can check by running the node -v command. If it outputs something like v14.0 or higher, then you're good to go! Otherwise, take a look at the page linked above for instructions on installing Node on your OS.

# Installing required packages

Without further ado, let us get started with our project.

mkdir eris-bot
cd eris-bot

Initialize the project:

npm init # fill out the questions

Feeling a bit lazy? Run npm init -y to have it fill everything out for you!
Install the packages needed:

npm i eris --no-optional # add the --no-optional flag to stop it from installing optional dependencies for voice support (that would need node-gyp)
npm i dotenv

If you want to install the dev version of Eris instead of the stable version, run the following:

npm install --no-optional abalabahaha/eris#dev

# Optional dependencies

There are a few optional dependencies that you can choose not to install.

• bufferutilopen in new window - WebSockets buffer utility (faster) (native)
• abalabahaha/erlpackopen in new window - Erlang Term Format encoder/decoder (might be faster) (native)
• pakoopen in new window - compression library (faster)
• zlib-syncopen in new window - compression library (faster than pako) (native)
• @discordjs/opusopen in new window - opus audio encoding (faster) (native)
• sodium-nativeopen in new window - audio encryption (faster) (native)
• eris-sharderopen in new window - sharding manager for the JavaScript eris library

Congrats! You have now installed all the required packages for your project.
