    Your comment touches on a few misconceptions I see a lot.

    Firstly, `reqwest` exposes both an async and a synchronous API, allowing the developer to choose which one to use. They are largely interchangeable code-wise. [1]

    Secondarily, and more broadly, async is possible to opt out of. You must understand that most web and network related libraries will be async by default for performance, because people who write in Rust and people who write web servers typically care greatly about performance. This is the intersection of those two groups. That being said, there are options outside of that ecosystem. [2]

    If you truly want to use an asynchronous library without migrating your application to run entirely on an async runtime like tokio, you can run it inside of a synchronous function without much trouble. I've put together a playground link for you. [3]

    There are several web frameworks for Rust: Rocket, Actix, Warp, Iron - but only Actix has released a stable 1.0 release, and there has been considerable controversy over how it uses unsafe Rust.

What are some alternatives?

When comparing fnm and Iron you can also consider the following projects:

nvm - Node Version Manager - POSIX-compliant bash script to manage multiple active node.js versions

Rocket - A web framework for Rust.

actix-web - Actix Web is a powerful, pragmatic, and extremely fast web framework for Rust.

nvm for Windows - A node.js version management utility for Windows. Ironically written in Go.

asdf - Extendable version manager with support for Ruby, Node.js, Elixir, Erlang & more

Gotham - A flexible web framework that promotes stability, safety, security and speed.

nodenv - Manage multiple NodeJS versions.

The FastCGI Rust implementation. - Native Rust library for FastCGI

volta - Volta: JS Toolchains as Code. ⚑
