Build Steps

Add Makefile:

# Binary name
BINARY_NAME=lrbooks

.PHONY: lint

lint:
	@echo "Linting..."
	cargo clippy

build:
	@echo "Building $(BINARY_NAME)..."
	cargo build --release --bin $(BINARY_NAME)

Clippy is a well-known linting tool for the Rust.

Update Cargo.toml to include the bin:

 version = "0.1.0"
 edition = "2021"
 
+[[bin]]
+name = "lrbooks"

Run make build to build a binary:

make build

This is equivalent to cargo build --release --bin lrbooks. It will create a binary file named lrbooks in your project’s target/release folder.

Make sure you have the config.toml config file in your project root directory, and all yours databases are ready to serve.

Then, you can just run it as a standalone server:

./target/release/lrbooks

You will see the start message like this:

🚀 Rocket has launched from http://127.0.0.1:8000

Send some requests with curl, you should be able to see some success responses.

It works like a charm! ⭐️
