Announcing the Spin Up Hub

Building a new application from scratch can be daunting and developers are no strangers to this. In fact, one of the reasons for the growing popularity of containers is the ease of starting application development from a verifiable base that can be easily shared between developers. We’ve truly been inspired by the great content generated by the Spin community, and we want to make it accessible for everyone to build and innovate upon. With that spirit in mind, we’re proud to announce the launch of Spin Up Hub - a single location to find and use Spin templates, libraries, and plugins. Built by Fermyon and the Spin community, for the Spin community.

These resources are the quickest way to start building your Spin application and allow you to easily create the skeleton of an application or component, ready for the custom business logic to be filled in. The aim of the Spin Up Hub is to produce re-useable components for Spin, and ultimately increase your productivity as a Spin developer. Read on to learn more about how you can get started with these templates and also contribute templates of your own to the Spin Up Hub.

Spin Up Hub, spiffily spun

The release of Spin 1.x included the ability to easily use templates, add pre-built components through spin add, and use plug-ins to extend the set of triggers available for Spin applications. Take for instance, Spin’s static fileserver. With spin add, adding a frontend component to your Spin application is quick and easy. The application manifest and file structure skeleton is magically set up on your behalf - all you have to focus on is adding custom logic to your frontend component.

A 3-tier app

Since then, we’ve been hard at work creating templates that make it easy for you to get started with Spin. With the release of Spin Up Hub, all templates and plug-ins have a centralised repository for easier access. Resources that have the ‘verified by Fermyon’ have either been developed by or have been vetted by the Fermyon team.

You can see in the table above that there are different resource types The following is a list of the types of resources available on the Spin Up Hub.

Getting started

Here’s how you get started using a Spin template

To list available templates, run spin templates list.

Adding a template to a Spin app is straightforward. Run spin add <template-name>This works similarly to spin new except that a pre-requisite is that spin.toml file should already exist. The details of the new components from the template are then added to that spin.toml file:

Scaffold a new component into an existing application

spin add --help

    spin add [OPTIONS] [ARGS]

    <TEMPLATE_ID>    The template from which to create the new application or component. Run `spin templates list` to see available options
    <NAME>           The name of the new application or component

Here’s how you get started using a Spin plugin

To list available plugins, run spin plugins list.

To install a Spin plugin you can use the following command:

spin plugins install <plugin-name>

spin <plugin-name>

With the plugin installed, you can now call spin <plugin name> to run it. For more info, you can read this page.
