A plugin that generates a CNAME file for the Publish static site generator. 🚀

CNAME plugin for Publish

A Publish plugin that generates a custom domain name file for any Publish website deployed to GitHub.

Background

When developing your own static website and deploying to GitHub Pages, you will most likely want to have your own custom domain. This requires having a custom domain name file, also known as a CNAME in the root directory of your website or the GitHub repository that your website is hosted on. When generating your site and pushing to GitHub, the CNAME file is removed since Publish will always push whatever files are generated in the dedicated Output directory. This plugin aims to generate a CNAME file into the Output directory that Publish uses for deploying your site to GitHub.

Installation

To install it into your Publish package, add it as a dependency within your Package.swift manifest:

let package = Package(
    ...
    dependencies: [
        ...
        .package(url: "https://github.com/SwiftyGuerrero/CNAMEPublishPlugin", from: "0.1.0")
    ],
    targets: [
        .target(
            ...
            dependencies: [
                ...
                "CNAMEPublishPlugin"
            ]
        )
    ]
    ...
)

Usage

In the file where you declare your Publish deployment pipeline, import CNAMEPublishPlugin:

import CNAMEPublishPlugin

The plugin can be installed at any point in the publishing pipeline, but before the deploy step:

import CNAMEPublishPlugin

...
try Website().publish(using: [
    ...
    .installPlugin(.generateCNAME(with: "test.io", "www.test.io")),
    .deploy(using: .gitHub("TestUser/TestUser.github.io"))
])

You can also add a CNAME to the Resources directory of your website and then use the addCNAME plugin to copy the CNAME to the output directory:

import CNAMEPublishPlugin

...
try Website().publish(using: [
    ...
    .installPlugin(.addCNAME()),
    .deploy(using: .gitHub("TestUser/TestUser.github.io"))
])

To verify that the file is generated and in the Output directory, you can use the publish run command to test publishing your site locally. Then in the created Output directory, you will see the generated CNAME as shown below:
