An opinionated framework for web development in rust.

Build Status

Fanta is a web framework that aims for developers to be productive and consistent across projects and teams. Its goals are to be:

  • Opinionated
  • Fast
  • Intuitive

Based heavily off of the work here: https://github.com/tokio-rs/tokio-minihttp


Fanta and Fanta-cli strive to give a good way to do domain driven design. It's also designed to let set you on the right path, but not obfuscate certain hard parts behind libraries.


Using the following command, we get roughly 96% of the speed of pure tokio-minihttp running in release mode.

wrk -t12 -c400 -d30s

Fanta results:

Based on frameworks like Koa, and Express, Fanta aims to be a pleasure to develop with.

Getting Started

Quick setup without a DB

The easiest way to get started is to just clone the starter kit

> git clone git@github.com:trezm/fanta-starter-kit.git
> cd fanta-starter-kit
> cargo run

The example provides a simple route plaintext route, a route with JSON serialization, and the preferred way to organize sub routes using sub apps.

Quick setup with postgres

The easiest way to get started with postgres is to install fanta-cli,

> cargo install fanta-cli

And then to run

> fanta-cli init MyAwesomeProject
> fanta-cli component Users
> fanta-cli migrate

Which will generate everything you need to get started! Note that this requires a running postgres connection and assumes the following connection string is valid:

postgres://postgres@localhost/<Your Project Name>

This is all configurable and none of it is hidden from the developer. It's like seeing the magic trick and learning how it's done! Check out the docs for fanta-cli here.



  • Breaking Changes
    • Migrated to use Futures for all middleware callbacks
  • Highlights
    • Dropped support for tree-based lookup of routes to remove potential branching
    • Removed many regexes involved in lookup
