Project Structure & Releases

This repository contains all components that make up TrailBase including client libraries, tests, documentation and examples. Only the benchmarks are kept separately due to their external dependencies.

Pre-built static binaries are available as GitHub releases for Linux, MacOS and Windows. On Windows the Docker image can be used.

Client packages for various languages are available via:

• JavaScript/TypeScript
• Dart/Flutter
• Rust
• C#/.Net
• Python

Running

You can get TrailBase either as a pre-built static binary (MacOS & Linux), run it using Docker (Windows, MacOS, Linux, ...), or build it from source.

The latest pre-built binaries can be downloaded from GitHub releases and run via:

$ ./trail run

Thanks to trail being a single static binary, there's no need to install anything including system dependencies. This also means that you can confidently update your system and deploy to different machines without having to worry about prior set-up or shared library compatibility.

Using Docker, you can run the following, which will also create and mount a local ./traildepot asset directory:

$ mkdir traildepot
$ alias trail="docker run -p 4000:4000 --mount type=bind,source=$PWD/traildepot,target=/app/traildepot trailbase/trailbase /app/trail"
$ trail run

To get a full list of commands, simply run trail --help .

Building

If you have all the necessary dependencies (Rust, protobuf, node.js, pnpm) installed, you can build TrailBase by running:

$ git submodule update --init --recursive
$ cargo build --release

To build a static binary you have to explicitly specify the target platform, e.g. for Linux using glibc:

$ RUSTFLAGS="-C target-feature=+crt-static" cargo build --target x86_64-unknown-linux-gnu --release

Alternatively, if you want to build a Docker image or don't have to deal with build dependencies, you can simply run:

$ git submodule update --init --recursive
$ docker build . -t trailbase

Contributing

Contributions are very much appreciated 🙏. For anything beyond bug fixes, let's briefly chat to see how a proposal fits into the overall roadmap and avoid any surprises.

We're not sure yet what the best setup or exact license is for compatibility between OSL-3.0 and more popular licenses or use as a framework. So we'd ask you to sign a simple CLA that retains your copyright, ensures that TrailBase will continue to forever be freely available under an OSI-approved copyleft license, while allowing for some flexibility and sub-licensing as established by much larger, successful projects such as Grafana or Element.

License

TrailBase is free software under the terms of the OSL-3.0.

We chose this license over more popular, similar copyleft licenses such as AGPLv3 due to its narrower definition of derivative work that only covers modifications to TrailBase itself. This is similar to GPL's classpath or LGPL's linkage exception allowing the use of TrailBase as a framework without inflicting licensing requirements on original work layered on top. That said, we ain't lawyers. The author of the license provides a more thorough explanation. If you have any concerns or advice for us, please reach out.

If you require an exception, reach out to contact@trailbase.io.
