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.

There is also an older (and slower) python backend in the backend folder.

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

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