How to Deploy Preact Apps on Spheron

This guide will show you how to deploy a Preact project and get your domain up. Preact (opens in a new tab) provides the thinnest possible Virtual DOM abstraction on top of the DOM. Preact is fast, and not just because of its size. It's one of the fastest Virtual DOM libraries out there, thanks to a simple and predictable diff implementation. We automatically batch updates and tune Preact to the extreme when it comes to performance. We work closely with browser engineers to get the maximum performance possible out of Preact.

Deploy Preact to Spheron

Follow these steps to deploy your Preact app on Spheron.

Step 1: Put Your Preact Project Code in a Git Repo

While this feature is not new to developers, the magic of Spheron is that every push to any branch in your GitHub, GitLab, or Bitbucket repo triggers a new build and deployment of your project.

Step 2: Deploy using the Spheron Platform UI.

You can create a new Spheron project using the platform UI. First, visit Spheron Network (opens in a new tab) in your browser. Choose your preferred Git provider from the options as seen above and authorize Spheron to access the repo you want to deploy. In the next screen, select your Preact repo from the list. Choose your preferred protocol where you want to deploy your static build. As of now, we support Arweave, Skynet, Filecoin & Pinata. You can choose any one protocol from all 4 of them. The third screen asks for details about where to create the project and how to build it. All the settings are already pre-filled based on the suggested framework. Learn more about each build setting. Check it out here (opens in a new tab).

1. Choose the branch to deploy from the dropdown and provide the root directory if you have a monorepo-like app structure.
2. Set the install command to yarn install
3. Set the build command to yarn build
4. Set the publish directory to build
5. You can add some environment variables before the build.
6. You can change the node engine of your deployment as well.
7. Click "Deploy"

That's All!

Now that you've deployed your preact project on Spheron, you have all the benefits of Spheron — including a custom deployment environment, continuous deployment whenever you push to your repo, and much more — as well as the benefits of preact like Preview Mode, Static site rendering. After deploying, your new preact project will automatically be assigned a .spheron.app suffixed domain. You can then add a Custom Domain (opens in a new tab) of your choice. We're so excited to see what you build with Preact on Spheron!
