Ignite is a static site builder for Swift developers, offering an expressive, powerful API to build beautiful websites that work great on all devices.

Ignite doesn't try to convert SwiftUI code to HTML, or simply map HTML tags to Swift code. Instead, it aims to use SwiftUI-like syntax to help you build great websites even if you have no knowledge of HTML or CSS.

Getting started

The easiest way to get started is to use the Ignite command-line tool included with this package:

1. Run git clone https://github.com/twostraws/Ignite to clone this repository to your computer.
2. Change into the new directory, e.g. cd Ignite.
3. Now run make to build the Ignite command-line tool.
4. Then run make install to install the Ignite command-line tool.
5. If that command fails because of permissions issues, you should run sudo make install instead.

Once that command-line tool is installed, you can run the following command to create a new site called ExampleSite:

ignite new ExampleSite

Once installed, the command-line tool is helpful for running a local web server for testing and for building your project.

Tip

Using the Ignite tool to run a local web server is the best way to preview your site.

Alternatively, you can bring Ignite into an existing project using Swift Package Manager by adding a package dependency for https://github.com/twostraws/Ignite.

Once that completes, import Ignite into your Swift code wherever needed:

import Ignite

Important: Previewing your site

Once you've built your site and are ready to see how it looks, do not just double-click one of the files in Finder. This will open the file directly in your browser, which means it won't know how to locate the rest of your site – the stylesheets, JavaScript code, etc – so it will not display correctly.

Instead, the best way to preview your site is using the Ignite CLI tool, which you installed in Getting Started above:

• Run ignite run --preview to preview your site and open it in your web browser.
• If Ignite tells you there is already a web server running on that port, run ignite run --preview --force.

That will open your web browser straight to your site. You can then return to Xcode and make changes to your site freely – every time you press Cmd+R to build your site, you can refresh your browser to see the changes.

See it in action

The IgniteSamples repository contains lots of sample code for you to try out – you can see it running here: You can see all the output from this repository running here: https://ignitesamples.hackingwithswift.com.

Basic Ignite code looks similar to SwiftUI code:

Text("Swift rocks")
    .font(.title1)
    
Text(markdown: "Add *inline* Markdown")
    .foregroundStyle(.secondary)

Link("Swift", target: "https://www.swift.org")
    .linkStyle(.button)

Divider()

Image("logo.jpg")
    .accessibilityLabel("The Swift logo.")
    .padding()

But it also includes a range of more advanced controls such as dropdown buttons:

Dropdown("Click Me") {
    Link("Accordions", target: AccordionExamples())
    Link("Carousels", target: CarouselExamples())
    Divider()
    Text("Or you can just…")
    Link("Go back home", target: "/")
}
.role(.primary)

It includes accordions that show or hide items based on what is selected:

Accordion {
    Item("First", startsOpen: true) {
        Text("This item will start open by default.")
    }

    Item("Second") {
        Text("This is the second accordion item.")
    }

    Item("Third") {
        Text("This is the third accordion item.")
    }
}
.openMode(.individual)

It has automatic code syntax highlighting for a dozen languages:

CodeBlock(language: "swift", """
struct ContentView: View {
    var body: some View {
        Text("Hello, Swift!")
    }
}
""")

Plus carousels, badges, alerts, tables, and so much more.

There is a separate repository called IgniteSamples, which provides sample code for a wide variety of protocols, elements, and modifiers used by Ignite.

If you're looking for code to help you get started, that's the best place – you can build that site and run it locally, the copy and paste any code you want to try.

Folder structure

Ignite sites are just Swift package, but they use a specific folder structure to help build your site effectively.

• Assets: This is where your custom site assets should be placed, using whatever subfolders you want.
• Build: This is created automatically by Ignite whenever you build your site. Do not place important information here, because it will be deleted on your next build.
• Content: This is where you want to place any Markdown files for posts you want, again using any subfolder structure you want. (Optional)
• Includes: This is where you place any custom HTML you've written that you want to include. (Optional)
• Sources: This is where you'll place all your Swift code for your site, using any subfolder structure that suits you.

This folder structure is already in place in the Ignite Starter Template repository, and I recommend you start with that.

Using the command-line tool

Once you have installed the Ignite command-line tool from this repository, you can use it in various ways.

First, you can create new site like this:

ignite new YourSite

When that completes, it will tell you the commands to use to open your new site for editing in Xcode:

cd YourSite
open Package.swift

Tip

If you want to build with Xcode, go to the Product menu and choose Destination > My Mac.

Back in your terminal window, once you have run that cd command the current working directory of your terminal is your website's directory. This means you can run the following command to build your site, rather than using Xcode:

ignite build

That will convert all your Swift code to HTML in your Build folder.

You can also run this command:

ignite run --preview

That will launch a local web server you should use to preview your site, and also open it in your browser. If you're working in Xcode, you can continue performing builds as normal then refresh your browser to see your changes.

Tip

The Ignite command-line tool has various configuration options available. Run ignite help to get general help, or add help before a subcommand to get further details, e.g. ignite help run.
