Custom Caddy Builder
====================

This package and associated CLI tool make it easy to perform custom builds of the [Caddy Web Server](https://github.com/caddyserver/caddy).

Supports Caddy 2 and up.

⚠️ Still in early development. Works; but no guarantees and prone to changes at this point. Stay updated and please submit feedback!

## Requirements

- Go installed
- Go modules enabled


## Library usage

```go
builder := xcaddy.Builder{
	CaddyVersion: "v2.0.0-rc.1",
	Plugins: []xcaddy.Dependency{
		{
			ModulePath: "github.com/caddyserver/nginx-adapter",
			Version:    "bdbb6db7ff9ad6ceb0dcd93f89e396f6365aa5d4",
		},
	},
}
err := builder.Build("./caddy")
```

Versions can be anything compatible with `go get`.


## CLI usage

The CLI can be used both to make custom builds of Caddy, but also as a replacement for `go run` while developing Caddy plugins.

### Download

```
go get -u github.com/caddyserver/xcaddy/cmd/xcaddy
```

### For custom builds

Syntax:

```
xcaddy build <version>
	[--output <file>]
	[--with <module[@version]>...]
```

Where:

- `--version` is the core Caddy version to build (required, for now).
- `--output` changes the output file.
- `--with` can be used multiple times to add plugins by specifying the module name and optionally its version, in a way similar to `go get`.

For example:

```bash
$ xcaddy build v2.0.0-rc.1 \
	--with github.com/caddyserver/nginx-adapter@bdbb6db7ff9ad6ceb0dcd93f89e396f6365aa5d4
```

### For plugin development

If you run `xcaddy` from within the folder of the Caddy plugin you're working on without the `build` subcommand, it will build Caddy with your current module and run it, similar to if you manually plugged it in and ran `go run`.

The binary will be built, run from the current directory, then cleaned up.

Syntax:

```
xcaddy <args...>
```

Where:

- `<args...>` are passed through to the `caddy` command.

For example:

```bash
$ xcaddy list-modules
$ xcaddy run --config caddy.json
```
