This repository contains a basic Rust application that serves a newsletter mailing list. The code is to learn from the book "Zero to Production" for the programming list Rust.

Start the app with

cargo run

Then send a request to the health endpoint

curl -v http://127.0.0.1:8000/health_check

Monitors source code to trigger commands every time a file changes.

install:

cargo install cargo-watch

cargo watch -x check -x test -x run

This tool extends Cargo to allow you to add, remove, and upgrade dependencies by modifying your Cargo.toml file from the command line.

install:

cargo install cargo-edit

cargo add
cargo rm
cargo upgrade
cargo set-version

The author is recommending 'cargo-tarpaulin'.

install:

cargo install cargo-tarpaulin

cargo tarpaulin --ignore-tests

Code linting is done by clippy.

rustup component add clippy

Use locally with

cargo clippy

In the CI pipeline the next command will let clippy fail if it finds something

cargo clippy -- -D warnings

The author recommends to use rustfmt to format the code.

rustup component add rustfmt

You can format your whole project with

cargo fmt 

In our CI pipeline we will add a formatting step

cargo fmt -- --check 

It will fail when a commit contains unformatted code, printing the difference to the console

The book recommends to use cargo-audit.

cargo install cargo-audit

Use like this

cargo audit
