The first step to start developing Micro-Rollups with Stackr is to prepare your development environment and making sure that all the system requirements are upto date and matches the required versions.

​
Install BunJS

Make sure you have the latest version of Bun installed that supports decorators >= 1.0.15

curl -fsSL https://bun.sh/install | bash

More information regarding Bun can be found at https://bun.sh

​
Install Rust

We recommend using Linux or macOS for development. If you are using Windows, you can install WSL2 and use Linux.

For Linux and macOS:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

​
Install Stackr-CLI

CLI helps you to create new projects, compile and deploy your micro-rollups.

For Mac ARM based chips:

curl -fsSL https://stackr-cli-bin.s3.ap-south-1.amazonaws.com/stackr-mac.sh | bash

For Linux :

sudo apt install gcc libssl-dev -y #Installs dependencies
curl -fsSL https://stackr-cli-bin.s3.ap-south-1.amazonaws.com/stackr-linux.sh | bash

And for all other systems

Rust installation comes with cargo package manager. We can also use cargo to install stackr-cli.

cargo install stackr

​
Install Javy

Directly install the binary for Mac with

curl -L https://github.com/bytecodealliance/javy/releases/download/v1.2.0/javy-arm-macos-v1.2.0.gz | gunzip > javy && chmod +x javy && sudo mv javy /usr/local/bin/

For Linux,

curl -L https://github.com/bytecodealliance/javy/releases/download/v1.2.0/javy-x86_64-linux-v1.2.0.gz | gunzip > javy && chmod +x javy && sudo mv javy /usr/local/bin/

This command asks for root permissions to move the binary to /usr/local/bin. Open a new terminal tab or source your shell to make sure the command runs.

javy --version

For other archs/platforms, please refer to the Releases page and curl the appropriate URL.

This is the recommended approach. However, if it does not work, please build Javy from source.

  • On Ubuntu, sudo apt-get install curl pkg-config libssl-dev clang
  • wasm32-wasi, can be installed via rustup target add wasm32-wasi
  • cmake, depending on your operating system and architecture, it might not be installed by default. On MacOS it can be installed with homebrew via brew install cmake. - On Ubuntu, sudo apt-get install cmake.
  • Rosetta 2 if running MacOS on Apple Silicon, can be installed via softwareupdate --install-rosetta

Then clone the repo and install javy cli globally:

git clone https://github.com/bytecodealliance/javy.git && cd javy
cargo build -p javy-core --target=wasm32-wasi -r
cargo install --path crates/cli
javy --version

Install git

You probably already have g(it).
