Substrate Package

A stable, known working version of the Substrate Node Template, Substrate Module Template, and Substrate Front End Template.

What is this?

• The fastest way to get started building on Substrate.
• Compatible with the latest documentation available for Substrate runtime module development.
• Using Substrate commit: d1cd01c74e8d5550396cb654f9a3f1b641efdf4c
• Using Polkadot-JS API version: ^0.95.0-beta.21

How to use it:

• Run git clone https://github.com/substrate-developer-hub/substrate-package.git.

• Run cd substrate-package.

• Run curl https://getsubstrate.io -sSf | bash -s -- --fast

  • This installs external dependencies needed for substrate. Take a look at the script.
  • The --fast command allows us to skip the cargo install steps for substrate and subkey, which is not needed for runtime development.
  • Windows users need to follow instructions here instead

• Go into the substrate-node-template folder and run:

  ./scripts/init.sh
  cargo build --release
  ./target/release/node-template --dev

  The above process may take 30 minuites or so, depending on your hardware. This should start your node, and you should see blocks being created.

• Go into the substrate-front-end-template folder and run:

  yarn install
  yarn start

  This should start a web server on localhost:3000 where you can interact with your node.

• Go into the substrate-module-template folder:

  • Read HOWTO.md
  • Edit /src/lib.rs to create a custom Substrate runtime module
  • Add dependencies to Cargo.toml with the appropriate rev

• Interact with your node and hack away!

What is the Substrate Module Template?

The substrate-module-template is a template where you can start building your own runtime module as it's own independent crate.

This is an alternative from writing your module in substrate-node-template/runtime/src/template.rs, where you would not be able to easily share your runtime module after your are done. We recommend development in the substrate-module-template if you want to allow others to include your runtime module into their Substrate node.

Instructions for using the substrate-module-template are included with the project.

We have added the Substrate module template as a dependency to the substrate-node-template, but if you want to remove it, you will need to:

1. Remove references from the runtime Cargo.toml file.
2. Remove references from the runtime lib.rs file.

How was it made?

This project simply clones the individual templates in a single place where they are tested to be compatible with one another.

git clone https://github.com/substrate-developer-hub/substrate-node-template
git clone https://github.com/substrate-developer-hub/substrate-module-template
git clone https://github.com/substrate-developer-hub/substrate-front-end-template

Why do I need substrate-package?

Substrate is a rapidly evolving platform, which means that breaking changes may occur on a day to day basis. Most of the times, these breaking changes do not radically change how substrate works, but may affect how Substrate is organized, the name of functions, the name of modules, etc...

The substrate-package repository tries to help solve these problems by taking a snapshot of substrate when it is known to be working and compatible with these different resources:

• Documentation
• Tutorials
• Samples
• User Interfaces
• etc...
