Caddy is a lightweight, general-purpose web server for Windows, Mac, Linux, BSD, and [Android](https://github.com/mholt/caddy/wiki/Running-Caddy-on-Android). It is a capable alternative to other popular web servers.
|
|
|
|
The most notable features are HTTP/2, Virtual Hosts, TLS + SNI, and easy configuration with a [Caddyfile](https://caddyserver.com/docs/caddyfile). Usually, you have one Caddyfile per site. Most directives for the Caddyfile invoke a layer of middleware which can be [used in your own Go programs](https://github.com/mholt/caddy/wiki/Using-Caddy-Middleware-in-Your-Own-Programs).

## Getting Caddy
|
|
|
|
Caddy binaries have no dependencies and are available for nearly every platform.
|
|
|
|
[Latest release](https://github.com/mholt/caddy/releases/latest)
|
|
|
|
|
|
## Running from Source
|
|
|
|
1. `$ go get github.com/mholt/caddy`
|
|
2. `cd` into your website's directory
|
|
3. Run `caddy` (assumes `$GOPATH/bin` is in your `$PATH`)
|
|
|
|
If you're tinkering, you can also use `go run main.go`.
|
|
|
|
By default, Caddy serves the current directory at [localhost:2015](http://localhost:2015). You can place a Caddyfile to configure Caddy for serving your site.
|
|
|
|
Caddy accepts some flags from the command line. Run `caddy -h` to view the help for flags.
|
|
|
|
|
|
#### 3rd-party libraries
|
|
|
|
Although Caddy's binaries are completely static, Caddy relies on some excellent libraries that really make the project possible.
|
|
|
|
- [bradfitz/http2](https://github.com/bradfitz/http2) for HTTP/2 support
|
|
- [russross/blackfriday](https://github.com/russross/blackfriday) for Markdown rendering
|
|
- [dustin/go-humanize](https://github.com/dustin/go-humanize) for pleasant times and sizes
|
|
- [flynn/go-shlex](https://github.com/flynn/go-shlex) to parse shell commands properly
|
|
|
|
This list may not be comprehensive, but [godoc.org](https://godoc.org/github.com/mholt/caddy) will list all packages that any given package imports.
|
|
|
|
## Quick Start
|
|
|
|
The website has [full documentation](https://caddyserver.com/docs) but this will get you started in about 30 seconds:
|
|
|
|
Place a file named "Caddyfile" with your site. Paste this into it and save:
|
|
|
|
```
|
|
localhost
|
|
|
|
gzip
|
|
browse
|
|
ext .html
|
|
websocket /echo cat
|
|
log ../access.log
|
|
header /api Access-Control-Allow-Origin *
|
|
```
|
|
|
|
Run `caddy` from that directory, and it will automatically use that Caddyfile to configure itself.
|
|
|
|
That simple file enables compression, allows directory browsing (for folders without an index file), serves clean URLs, hosts an echo server for WebSocket connections at /echo, logs accesses to access.log, and adds the coveted `Access-Control-Allow-Origin: *` header for all responses from some API.
|
|
|
|
Wow! Caddy can do a lot with just a few lines.
|
|
|
|
#### Defining multiple sites
|
|
|
|
You can run multiple sites from the same Caddyfile, too:
|
|
|
|
```
|
|
http://mysite.com,
|
|
http://www.mysite.com {
|
|
redir https://mysite.com
|
|
}
|
|
|
|
https://mysite.com {
|
|
tls mysite.crt mysite.key
|
|
# ...
|
|
}
|
|
```
|
|
|
|
Note that the secure host will automatically be served with HTTP/2 if the client supports it.
|
|

Thanks for making Caddy -- and the Web -- better!

## About the project
|
|
|
|
Caddy was born out of the need for a "batteries-included" web server that runs anywhere and doesn't have to take its configuration with it. Caddy took inspiration from nginx, lighttpd, Websocketd, and Vagrant, and provides a pleasant mixture of features from each of them.
