# Introduction
|
|
|
|
Rocket is a web framework for Rust. If you'd like, you can think of Rocket as
|
|
being a more flexible, friendly medley of [Rails](https://rubyonrails.org/),
|
|
[Flask](https://palletsprojects.com/p/flask/),
|
|
[Bottle](https://bottlepy.org/docs/dev/index.html), and
|
|
[Yesod](https://www.yesodweb.com/). We prefer to think of Rocket as something
|
|
new. Rocket aims to be fast, easy, and flexible while offering guaranteed safety
|
|
and security where it can. Importantly, Rocket also aims to be _fun_, and it
|
|
accomplishes this by ensuring that you write as little code as needed to
|
|
accomplish your task.
|
|
|
|
This guide introduces you to the core, intermediate, and advanced concepts of
|
|
Rocket. After reading this guide, you should find yourself being very
|
|
productive with Rocket.
|

|
## Audience
|
|
|
|
Readers are assumed to have a good grasp of the Rust programming language.
|
|
Readers new to Rust are encouraged to read the [Rust
|
|
Book](https://doc.rust-lang.org/book/). This guide also assumes a basic
|
|
understanding of web application fundamentals, such as routing and HTTP. Mozilla
|
|
provides a good overview of these concepts in their [MDN web docs].

## Foreword
|
|
|
|
Rocket's design is centered around three core philosophies:
|
|
|
|
* **Security, correctness, and developer experience are paramount.**
|
|
|
|
The path of least resistance should lead you to the most secure, correct web
|
|
application, though security and correctness should not come at the cost of
|
|
a degraded developer experience. Rocket is easy to use while taking great
|
|
measures to ensure that your application is secure and correct without
|
|
cognitive overhead.
|
|
|
|
* **All request handling information should be typed and self-contained.**
|
|
|
|
Because the web and HTTP are themselves untyped (or _stringly_ typed, as
|
|
some call it), this means that something or someone has to convert strings
|
|
to native types. Rocket does this for you with zero programming overhead.
|
|
What's more, Rocket's request handling is **self-contained** with zero
|
|
global state: handlers are regular functions with regular arguments.
|
|
|
|
* **Decisions should not be forced.**
|
|
|
|
Templates, serialization, sessions, and just about everything else are all
|
|
pluggable, optional components. While Rocket has official support and
|
|
libraries for each of these, they are completely optional and swappable.
|
|
|
|
These three ideas dictate Rocket's interface, and you will find all of them
|
|
embedded in Rocket's core features.
