Rust auto reload with cargo watch

Nodemon

When I develop a node.js application, I don’t enter the run command since there is a nodemon that automatically restarting the application when file changes in the directory are detected. The same you can find in Rust is Cargo Watch.

cargo-watch

At first, you need to install the cargo-watch using this command.

$ cargo install cargo-watch

After the installation is ok, we can run it by hitting this command.

$ cargo watch [-x command]...

I found this when I read the actix-web official document. It seems that cargo watch applies to every Rust project.

For the actix-web project, I use this.

$ cargo watch -x run
