Jankboard

This repository hosts the source tree for the Jankboard.

Jankboard is the fully custom control interface designed in-house by Team 1280 for the 2024 season of the FIRST Robotics Competition. The FIRST Robotics Competition is an international high-school robotics competition which runs annually. Teams spend six weeks designing, prototyping, and building a robot to compete in each year's game. The goals for each game vary by year.

You can try it out effortlessly on Linux and macOS if you have the Nix package manager installed with flakes enabled. This repository provides a Nix flake that hermetically compiles Jankboard from source.

nix run github:team-1280/jankboard

On Windows, download the latest release, compiled by GitHub Actions builders.

Or, you can compile it with the installation instructions detailed below.

The Jankboard is a fully functional control interface designed to be used with our 2024 robot. It is intended to work alongside the FRC Game Tools application, which is required by the rules to handle processing robot control inputs. The Jankboard is a dashboard which receives the telemetry data from the robot and displays it for the driver. It also processes it to provide useful features. It replaces the standard "Shuffleboard" dashboard program provided by FIRST, and has a much cleaner and purpose-built UI.

Jankboard is built with Tauri, which is a framework for building desktop application with Rust and webviews. Unlike Electron, it leverages the platforms built-in web technologies (Chromium on Windows, WebKit on Linux and MacOS) to avoid shipping a massive bloated binary with a bundled browser. Our (my) choice of web framework is Svelte, a modern framework with a compiler. To interface with and collect telemetry from the robot, a Rust backend implements the low-level networking and communication details and streams the received data back to the frontend UI. As soon as new data is received, the frontend is updated immediately. We found that this provided more than enough speed for our purposes, since the robot sends new telemetry at a rate of 10 Hz. We chose this tech stack because building beautiful and functional UIs is easiest with the Web, and it allowed us to rapidly build the application during our 6-week development period.

Additionally, the repository serves as a reference example of how to do Tauri development in a pure, reproducible Nix shell. You are still able to do live iteration using pnpm dev, but you can hermetically build the program using the nix CLI. See the nix files for more.

Installation guide

We recommend installing the latest stable release binaries from our release page, if you're just looking to run the Jankboard. Alternatively, if you can't find release binaries for your system, follow the directions below in the For developers section to build it from source. We will periodically update the releases with new builds when we come out with stable versions, and we follow semantic versioning.

A brief note on the name "Jankboard"

The name "Jankboard" comes from Team 1280's original attempt at creating a custom dashboard. Though it looked and functioned superficially similar to Jankboard, it was not designed with maintainability in mind and became exceptionally difficult to extend and develop as the codebase became bloated. Jankboard is a version redesigned from the ground up with the goal of easy maintainability and richer features. It contains both a completely rewritten frontend and backend, which have been improved in almost every possible way.

For developers

If you would like to contribute to Jankboard, there's only a few simple steps to get the development build up and running. Please keep in mind that the following is only necessary if you are building from source; the binaries have no external dependencies.

The preferred way to run Jankboard on Linux and macOS is to use the Nix package manager. However, the below instructions detail how to install and use the required dependencies manually.

Prerequisites

• Rust and cargo. Check the Rust docs for more information.
• pnpm, for installing dependencies and the vite development server.
• NodeJS

Installation steps

1. Clone the repository using your preferred method.
2. Enter the client directory. This is where the majority of the app's source code lives.
3. Run pnpm install to download all required NPM dependencies.
4. Run pnpm run build-splash to compile the splash screen.
5. To create a production build, run pnpm tauri build. This will use Cargo to fetch and build all the Rust dependencies, then compile the app and output an executable for your platform in target.
6. To launch a developer build with hot reloading and convenient debugging features, run pnpm tauri dev.

Some notes:

• The client directory contains the vast majority of the source code for the desktop app, while the splash-screen directory contains the source code for the splash screen displayed before the app loads. You don't have to touch anything in splash-screen unless you want to modify it, in which case check the README in splash-screen for more information.

• Tauri cross-compilation is still in beta, so you should build targeting the same OS you're currently running. For example, create Windows builds from Windows. Check the Tauri docs for more information. We also have some Github Actions set up to automatically compile a production build for all platforms, but this is expensive (uses over 30 minutes of our quota), and should only be used for publishing new major releases.

Troubleshooting common issues

• If you're experiencing issues with TypeScript type checking or dependency resolution, try opening your editor directly in the client directory so it picks up the tsconfig.json and uses the project's own TypeScript language server.

Licensing

This project is released as free software under the terms of the GNU General Public License. What that entails for a developer seeking to use portions of this codebase, or even the entirety of the codebase, for their own purposes, is the following:

You are given the freedom (rights) to copy, modify, and distribute this software, in its entirety or just a portion of it, with or without modification, provided you meet the following requirements:

• If you do make modifications to the software, you are required to release the source code of your modifications, also under the terms of the GPL v3, if you are planning to distribute the software. However, this is not required if you are not planning to distribute it. See below.
• You may modify or use it however you'd like personally or internally (within an organization, like your robotics team), without releasing your changes or code under the GPL. This means that if you make a custom dashboard based on this code for your own robotics team, you do not have to release the code as long as you are not planning to distribute your custom dashboard to other robotics teams or publish it publicly on the internet. If you do intend to distribute it, then you must release the modified source under the terms of the GPL v3.
  • We think that this is fair - if you intend to keep an internal private tool, we should not stop you from doing so. However, if you intend to publish your tool or share it with others, then you should also publish or share the source code for the benefit of other developers and robotics teams, as we have done here.

See the full license text of the GPL if you need further clarification. The above is simply an explanation of the license, if any conflicts between the above text and the license text arise, then the original license text takes precedence.
