Prometeo CLI

This tool was developed during a hackathon promoted by the Ignite Community.

The challenge was to develop a CLI that could interact with the Prometeo Open Banking API.

Running it

Downloading the binaries

Get them from Releases, the exe file is for Windows while the other is for GNU/Linux, or as I've recently taken to calling it, GNU plus Linux.

Building the binaries

Make sure you have rust installed in your system, if you don't, get it from here.

For host OS

You can simply run cargo build -r

For any other OS

Check out cross

For example, as my host OS is Arch Linux (btw), I had to use the following command to make a build for Windows:

cross build --target x86_64-pc-windows-gnu

On GNU plus Linux

• chmod +x prometeo-cli
• ./prometeo-cli

On Windows

./prometeo-cli.exe

Tech stack

Rust

Why?

Every developer should have at least one project written in Rust otherwise you're irrelevant

Crates used:

• reqwest: makes requests
• tokio: asynchronous support for rust
• dialoguer: those nice menus you saw
• colored: adds colors to the displayed messages
• serde: for serialization
• serde_json: for json support
• jfs: abstraction to read and write json to the filesystem
• dirs: cross-platform directories (such as ~/.config or /home/${username})

JSON

You can store things with it, gets the job done. Storing data such as api_key, user_key and username seems convenient, although a safer approach might be preferable.
