Joystream

This is the main code repository for all Joystream software. In this mono-repo you will find all the software required to run a Joystream network: The Joystream full node, runtime and all reusable substrate runtime modules that make up the Joystream runtime. In addition to all front-end apps and infrastructure servers necessary for operating the network.

Overview

The Joystream network builds on the substrate blockchain framework, and adds additional functionality to support the various roles that can be entered into on the platform.

Development

For best results use GNU/Linux with minimum glibc version 2.28 for nodejs v18 to work. So Ubuntu 20.04 or newer.

You can check your version of glibc with ldd --version

The following tools are required for building, testing and contributing to this repo:

• Rust toolchain - required
• nodejs >= v14.18.x - required (However volta will try to use v18.6)
• yarn classic package manager v1.22.x- required
• docker v2.20.x or higher - required
• ansible - optional

If you use VSCode as your code editor we recommend using the workspace settings for recommend eslint plugin to function properly.

After cloning the repo run the following to get started:

Install development tools

./setup.sh

If you prefer your own node version manager

Install development tools without Volta version manager.

./setup.sh --no-volta

For older operating systems which don't support node 18

Modify the root package.json and change volta section to use node version 16.20.1 instead of 18.6.0

"volta": {
    "node": "16.20.1",
    "yarn": "1.22.19"
}

Run local development network

# Build local npm packages
yarn build

# Build joystream/node docker testing image

Contributing

We have lots of good first issues open to help you get started on contributing code. If you are not a developer you can still make valuable contributions by testing our software and providing feedback and opening new issues.

A description of our branching model will help you to understand where work on different software components happens, and consequently where to direct your pull requests.

We rely on eslint for code quality of our JavaScript and TypeScript code and prettier for consistent formatting. For Rust we rely on rustfmt and clippy.

The husky npm package is used to manage the project git-hooks. This is automatically installed and setup when you run yarn install.

When you git commit and git push some scripts will run automatically to ensure committed code passes lint, tests, and code-style checks.

During a rebase/merge you may want to skip all hooks, you can use HUSKY_SKIP_HOOKS environment variable.

HUSKY_SKIP_HOOKS=1 git rebase ...

RLS Extension in VScode or Atom Editors

If you use RLS extension in your IDE, start your editor with the BUILD_DUMMY_WASM_BINARY=1 environment set to workaround a build issue that occurs in the IDE only.

BUILD_DUMMY_WASM_BINARY=1 code ./joystream
