From POSTMAN to Rust: Introducing getsb-cli for Command-Line HTTP Requests

From POSTMAN to Rust: Introducing getsb-cli

Hi everyone, I’m excited to share my latest project with you all. Two weeks ago, I started learning Rust for better development experience, and as a part of my learning process, I decided to rewrite my mruby-smallhttp library in Rust.

During my Rust learning process, I discovered Cargo, which is similar to the bundler in the Ruby world. With Cargo, I was able to generate a template for my Rust project, including the Cargo.toml manifest file and the file, which serves as the main file for a Rust library.

If you’re interested in learning more about Rust, check out the Rust-Lang website and The Rust Programming Language Book.

Once I had my Rust library set up, I decided to write a command-line tool for sending HTTP requests. Previously, I had been using POSTMAN, but I wasn’t a fan of the Electron framework it used. I don’t like Chrome at all, and using it to work with POSTMAN was too much for me. So, I decided to use my knock library to write a command-line tool in Rust.

I quickly wrote the tool, which I named getsb, and I had to add some code to my knock library. Currently, getsb is at version v0.1.0, and I’m planning to add more features to it soon. I would be grateful for any help in improving it.

To install getsb, follow these steps:

$ git clone
$ cd getsb-cli
$ cargo build --release

After that, move the binary file to the bin directory.

For Linux:

$ sudo mv target/release/getsb /usr/local/bin

For macOS:

$ sudo mv target/release/getsb /usr/local/bin/getsb

For Windows, create a folder for getsb and add it to your PATH environment variable.

To use getsb, run the following command:

$ getsb POST -b "key=value" -h "Content-Type: application/x-www-form-urlencoded"

For more information on using getsb, check out the file.

Overall, I really enjoyed working with Rust. It’s an awesome language that allows for safe memory management and has many other great features.

If you’re interested in learning Rust, I highly recommend checking out the Rust Programming Language Book and the Awesome Rust repository.

Thank you for reading, and I hope this post has inspired you to start learning Rust!
