# Rocket Examples
This directory contains projects showcasing Rocket's features.
## Applications
* **[`pastebin`](./pastebin)**
A simple, API-only pastebin application, similar to https://paste.rs. Stores
pastes locally on the file system. Implements a custom parameter guard,
`PasteId`, to parse and validate paste identifiers.
* **[`todo`](./todo)**
A todo app with a web UI to add, delete, and mark/unmark items. Uses a
SQLite database driven by diesel. Runs migrations automatically at start-up.
Uses tera to render templates.
* **[`chat`](./chat)**
A real-time, multi-room chat application using Server-Sent Events (SSE) and
JavaScript's `EventSource`. Supports automatic reconnection with exponential
backoff and live connection status.
## Feature Examples
* **[`config`](./config)** - Illustrates how to extract values from a Rocket
`Figment`, how to store and retrieve an application specific configuration
in managed state using `AdHoc::config()`, and how to set configuration
values in `Rocket.toml`.
* **[`cookies`](./cookies)** - Uses cookies to create a client-side message
box. Uses private cookies for a session-based authentication.
* **[`databases`](./databases)** - Implements a CRUD-like "blog" JSON API
backed by a SQLite database driven by each of `sqlx`, `diesel`, and
`rusqlite`. Runs migrations automatically for the former two drivers. Uses
`contrib` database support for all drivers (`rocket_db_pools` for the first;
`rocket_sync_db_pools` for the other latter two).
* **[`error-handling`](./error-handling)** - Exhibits the use of scoped
catchers; contains commented out lines that will cause a launch-time error
with code to custom-display the error.
* **[`fairings`](./fairings)** - Exemplifies creating a custom `Counter`
fairing and using `AdHoc` fairings.
* **[`forms`](./forms)** - Showcases all of Rocket's form support features
including multipart file uploads, ad-hoc validations, field renaming, and
use of form context for staged forms.
* **[`hello`](./hello)** - Basic example of Rocket's core features: route
declaration with path and query parameters, both simple and compound,
mounting, launching, testing, and returning simple responses. Also showcases
using UTF-8 in route declarations and responses.
* **[`manual-routing`](./manual-routing)** - An example eschewing Rocket's
codegen in favor of manual routing. This should be seen as last-ditch
effort, much like `unsafe` in Rust, as manual routing _also_ eschews many of
Rocket's automatic web security guarantees.
* **[`responders`](./responders)** - Illustrates the use of many of Rocket's
built-in responders: `Stream`, `Redirect`, `File`, `NamedFile`, `content`
for manually setting Content-Types, and `Either`. In the process, showcases
using `TempFile` for raw uploads. Also illustrates the creation of a custom,
derived `Responder`.
* **[`serialization`](./serialization)** - Showcases JSON and MessagePack
(de)serialization support by implementing a CRUD-like message API in JSON
and a simply read/echo API in MessagePack. Showcases UUID parsing support.
* **[`state`](./state)** - Illustrates the use of request-local state and
managed state. Uses request-local state to cache "expensive" per-request
operations. Uses managed state to implement a simple index hit counter. Also
uses managed state to store, retrieve, and push/pop from a concurrent queue.
* **[`static-files`](./static-files)** - Uses `FileServer` to serve static
files. Also creates a `second` manual yet safe version.
* **[`templating`](./templating)** - Illustrates using `contrib` `templates`
support with identical examples for handlebars and tera.
* **[`testing`](./testing)** - Uses Rocket's `local` libraries to test an
application. Showcases necessary use of the `async` `Client`. Note that all
examples contains tests, themselves serving as examples for how to test
Rocket applications.
* **[`tls`](./tls)** - Illustrates configuring TLS with a variety of key pair
kinds.
* **[`upgrade`](./upgrade)** - Uses the connection upgrade API to implement
WebSocket support using tungstenite.
