Development environment ​

This page will go over setting up your development environment to run Celestia software. This environment can be used for development, building binaries, and running nodes.

Install dependencies ​

  1. If you are on Ubuntu, first update and upgrade your OS:

    bash
    sudo apt update && sudo apt upgrade -y
    sudo apt update && sudo apt upgrade -y
    bash
    sudo yum update
    sudo yum update

  2. Install essential packages that are necessary to execute many tasks like downloading files, compiling, and monitoring the node:

    bash
    sudo apt install curl tar wget aria2 clang pkg-config libssl-dev jq build-essential \
git make ncdu -y
    sudo apt install curl tar wget aria2 clang pkg-config libssl-dev jq build-essential \
git make ncdu -y
    bash
    sudo yum install curl tar wget aria2 clang pkg-config libssl-dev jq build-essential \
git make ncdu -y
    sudo yum install curl tar wget aria2 clang pkg-config libssl-dev jq build-essential \
git make ncdu -y
    bash
    # these commands are for installing Homebrew, wget and jq
# follow the instructions from the output after running this command
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

# then install wget & jq
brew install wget && brew install jq
    # these commands are for installing Homebrew, wget and jq
# follow the instructions from the output after running this command
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

# then install wget & jq
brew install wget && brew install jq

Install Golang ​

celestia-node is written in Golang so we must install Golang to build and run our node.

  1. Set the version for your desired network:

    bash
    ver="1.21.1"
    ver="1.21.1"
    bash
    ver="1.22.0"
    ver="1.22.0"
    bash
    ver="1.22.0"
    ver="1.22.0"

  2. Download and install Golang:

    bash
    cd $HOME
wget "https://golang.org/dl/go$ver.linux-amd64.tar.gz"
sudo rm -rf /usr/local/go
sudo tar -C /usr/local -xzf "go$ver.linux-amd64.tar.gz"
rm "go$ver.linux-amd64.tar.gz"
    cd $HOME
wget "https://golang.org/dl/go$ver.linux-amd64.tar.gz"
sudo rm -rf /usr/local/go
sudo tar -C /usr/local -xzf "go$ver.linux-amd64.tar.gz"
rm "go$ver.linux-amd64.tar.gz"
    bash
    cd $HOME
wget "https://golang.org/dl/go$ver.linux-arm64.tar.gz"
sudo rm -rf /usr/local/go
sudo tar -C /usr/local -xzf "go$ver.linux-arm64.tar.gz"
rm "go$ver.linux-arm64.tar.gz"
    cd $HOME
wget "https://golang.org/dl/go$ver.linux-arm64.tar.gz"
sudo rm -rf /usr/local/go
sudo tar -C /usr/local -xzf "go$ver.linux-arm64.tar.gz"
rm "go$ver.linux-arm64.tar.gz"
    bash
    cd $HOME
wget "https://golang.org/dl/go$ver.darwin-arm64.tar.gz"
sudo rm -rf /usr/local/go
sudo tar -C /usr/local -xzf "go$ver.darwin-arm64.tar.gz"
rm "go$ver.darwin-arm64.tar.gz"
    cd $HOME
wget "https://golang.org/dl/go$ver.darwin-arm64.tar.gz"
sudo rm -rf /usr/local/go
sudo tar -C /usr/local -xzf "go$ver.darwin-arm64.tar.gz"
rm "go$ver.darwin-arm64.tar.gz"
    bash
    cd $HOME
wget "https://golang.org/dl/go$ver.darwin-amd64.tar.gz"
sudo rm -rf /usr/local/go
sudo tar -C /usr/local -xzf "go$ver.darwin-amd64.tar.gz"
rm "go$ver.darwin-amd64.tar.gz"
    cd $HOME
wget "https://golang.org/dl/go$ver.darwin-amd64.tar.gz"
sudo rm -rf /usr/local/go
sudo tar -C /usr/local -xzf "go$ver.darwin-amd64.tar.gz"
rm "go$ver.darwin-amd64.tar.gz"

  3. Add your /usr/local/go/bin directory to your $PATH if you have not already:

    bash
    echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> $HOME/.bash_profile
source $HOME/.bash_profile
    echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> $HOME/.bash_profile
source $HOME/.bash_profile
    bash
    echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> $HOME/.zshrc
source $HOME/.zshrc
    echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> $HOME/.zshrc
source $HOME/.zshrc

  4. To verify that the correct version of Go was installed correctly run:

    bash
    go version
    go version

The output will show the version installed.
