Development

To run all tests run

# Run tests (general)
cargo test --features math,docs,ssr

# Run tests (axum) use_cookie
cargo test --features math,docs,ssr,axum --doc use_cookie

# Run tests (axum) use_locale
cargo test --features math,docs,ssr,axum --doc use_locale

# Run tests (actix) use_cookie
cargo test --features math,docs,ssr,actix --doc use_cookie

# Run tests (actix) use_locale
cargo test --features math,docs,ssr,actix --doc use_locale

Book

First you need to install

cargo install mdbook mdbook-cmdrun trunk

To build the book go in your terminal into the docs/book folder and run

mdbook serve

This builds the html version of the book and runs a local dev server. To also add in the examples open another shell and run

python3 post_build.py

If you only want to add the example for one function you can run for example

python3 post_build.py use_storage

New Function Template

To scaffold a new function quickly you can run template/createfn.sh. It requires that ffizer and Python 3 is installed. This will create the function file in the src directory, scaffold an example directory and an entry in the book.
