Templates are a Spin tool for scaffolding new applications and components. You can use them via the
spin new and
spin add commands. For more information about creating applications with templates, see Writing Spin Applications.
This section covers general principles for installing templates. For information about installing templates for specific languages, see Writing Spin Applications.
To install templates, use the
spin templates install command. You can install templates from a Git repository, or while authoring templates you can install them from a local directory.
Installing From the Spin Git Repository
To install templates from the Spin Git repository, run
spin templates install --git.
$ spin templates install --git https://github.com/fermyon/spin
The above command installs all templates in the repository.
Language SDKs often ship templates in their repositories; see the relevant language guide to find out where to get its templates.
Installing From a Specific Branch
By default, if you install templates from a Git repository, Spin tries to find a repo tag that matches the version of Spin, and installs from that tag. Failing this, it installs from
HEAD. If you would like to install from a specific tag or branch, pass the
$ spin templates install --git https://github.com/fermyon/spin --branch spin/templates/v0.8
Installing From a Local Directory
To install templates from your local file system, run
spin templates install --dir.
The directory you pass must be one that contains a
templatesdirectory. Don’t pass the
# Expects to find a directory ~/dev/spin-befunge-sdk/templates $ spin templates install --dir ~/dev/spin-befunge-sdk
See Template Authoring for more details on this layout.
Viewing Your Installed Templates
To see what templates you have installed, run
spin templates list.
You can use the
--verbose option to see additional information such as where they were installed from.
You can uninstall templates using
spin templates uninstall with the template name:
$ spin templates uninstall redis-befunge
Spin doesn’t currently support uninstalling a whole repo-worth of templates, only individual templates.
When you upgrade Spin, you will typically want to upgrade your templates to match. This means new applications and components will get dependencies that match the Spin version you are using. To do this, run
spin templates upgrade:
$ spin templates upgrade Select repos to upgrade. Use Space to select/deselect and Enter to confirm selection. [x] https://github.com/fermyon/spin-python-sdk [ ] https://github.com/fermyon/spin (at spin/templates/v1.0) > [x] https://github.com/fermyon/spin-js-sdk
Use the cursor keys and the space bar to select the repositories you want to upgrade, then hit Enter to upgrade the selected repositories.
Upgrading happens at the repo level, not the individual template level. If you’ve uninstalled templates, upgrading the repo they came from will bring them back.
If you want to upgrade all repositories without being prompted, run
spin templates upgrade --all.
As mentioned above, if you want to check which templates come from which repositories use
spin templates list --verbose.
Upgrading Templates From a Local Directory
spin templates upgrade only upgrades from Git repositories. If you want to upgrade and your templates are in a local directory, run the
spin templates install command with the
$ spin templates install --dir ~/dev/spin-befunge-sdk --upgrade
