# Examples

Welcome to the examples! These show off `warp`'s functionality and explain how to use it.

## Getting Started

To get started, run `examples/hello.rs` with:

```bash
> cargo run --example hello
```

This will start a simple "hello world" service running on your localhost port 3030.

Open another terminal and run:

```bash
> curl http://localhost:3030/hi
Hello, World!%
```

Congratulations, you have just run your first warp service!

You can run other examples with `cargo run --example [example name]`:

- [`hello.rs`](./hello.rs) - Just a basic "Hello World" API
- [`routing.rs`](./routing.rs) - Builds up a more complex set of routes and shows how to combine filters
- [`body.rs`](./body.rs) - What's a good API without parsing data from the request body?
- [`headers.rs`](./headers.rs) - Parsing data from the request headers
- [`rejections.rs`](./rejections.rs) - Your APIs are obviously perfect, but for silly others who call them incorrectly you'll want to define errors for them
- [`futures.rs`](./futures.rs) - Wait, wait! ... Or how to integrate futures into filters
- [`todos.rs`](./todos.rs) - Putting this all together with a proper app

## Further Use Cases
