Tenebrous Sheets
An open source character sheet service for tabletop roleplaying games.
Currently under heavy development.
The Stack
This project makes use of these technologies:
- Rust
- Rocket Web Framework
- Tonic gRPC Framework
- Typescript
Building is backed by: cargo, npm, and webpack.
Build Instructions
These are very basic build instructions. They assume you already have cargo set up and installed.
Initial Setup
Quick initial setup instructions that will set up a development environment.
First, install dependencies by either using the command below (Void Linux), or reading the "Dependencies Required" section:
xbps-install sqlite sqlite-devel protobuf nodejs docker
Then run the required cargo commands to install management tools and
create a development database:
cargo install --version=0.2.0 sqlx-cli
cargo install cargo-run-script
cargo run --bin tenebrous-migrate
Dependencies Required
Dependencies required to build the project. The exact installation method depends on your OS.
- sqlite3 and development headers (Void Linux:
xbps-install sqlite sqlite-devel, Ubuntu:apt install sqlite3 libsqlite3-dev). - protoc: protocol buffers compiler. Needed to compile protobuf files
for both the server and web frontends (Void Linux:
xbps-install protobuf). - Node and npm: Needed to run webpack for compiling and injecting
Typescript into various web pages (Void Linux:
xbps-install nodejs). - Docker: Needed to run the grpc proxy (Void Linux
xbps-install docker).
Run Application
Command line "instructions" to build and run the application:
cargo run-script grpc-proxy # only required if proxy not already running
cargo run
The sqlite database is created in the directory cargo run was
invoked from by default. You can also pass a path to a different
location as a single argument to the program.
Development
Development instructions.
To set up a local database, or run migrations, run:
cargo run --bin tenebrous-migrate
Database Queries and Migrations
When adding/updating a compile-checked query or a migration, you need to update the SQLx data JSON file:
cargo sqlx prepare -- --bin tenebrous
gRPC-Web Proxy
The frontend web application makes use of the gRPC-Web protocol to
call gPRC endpoints from the browser. This requires a proxy to
translate the calls from the browser to HTTP2 calls gRPC understands.
For development, executing the cargo run-script grpc-proxy command
will start the envoy proxy recommended by Google's gRPC-Web project.
The envoy configuration assumes you are on Linux. If you are using Mac OS or Windows, see the note in the envoy configuration.
