Glide area calculator

This is a web application to calculate the glide area for paragliders.

Running locally

The easiest way to run this application on your computer is using the provided docker image:

$ docker run -p 8080:8080 hoff97/hikeandfly:latest

You can then access the application at http://localhost:8080.

The docker image can be built with

$ docker buildx build --progress=plain -t hoff97/hikeandfly:latest ./

This will download some data for the digital evelation model (DEM). Change backend-rust/download_data.sh according to your needs if you do not want to download all the data.

Development

Frontend

The frontend is built with react and can be run with

$ cd frontend
$ npm install
$ npm run start

Backend

The backend is built with rust. Run it in development mode using:

$ cd backend-rust
$ download_data.sh
$ cargo run

This might be a bit slow, alternatively, you can use cargo run --release. backend-rust/download_data.sh will download some data for the digital evelation model (DEM). Change backend-rust/download_data.sh according to your needs if you do not want to download all the data.

Performance testing

You can run performance tests using

$ cargo bench

A flamegraph can be generated by adding the following to Cargo.toml:

[profile.release]
debug = 1

and then running

$ sudo sysctl kernel.perf_event_paranoid = -1 #Only needed once to enable event counting for flamegraph
$ cargo flamegraph --bench search_benchmark -- --bench
