Visit a professional woodshop and ask a master carpenter what her favourite tool is. You may find it’s not a tool in the traditional sense, but a “jig” she built. In woodworking, jigs are patterns or templates built to make repeatable tasks more efficient and outcomes more consistent. Building a one-off bookcase may not warrant building a jig. But, if you’re building three or four of the same bookcase, it’s likely worth building a jig first, then using that jig to build the bookcases.
Once upon a time I was a carpenter and I made… mostly sawdust. Nowadays I work for Automattic, on a small team which makes… mostly websites. While each of our projects is unique in some aspects, the vast majority share this common foundation:
- A repository on GitHub
- A WordPress site
- A DeployHQ configuration to link those platforms together
- A distributed team of designers, developers and producers throwing pixels and puns around on Slack
We have a creed at Automattic which states:
Open Source is one of the most powerful ideas of our generation.
In celebration of that belief and in appreciation of the service DeployHQ provides our team, I’m happy to share a jig our team built to bootstrap new projects.
Our jig consists of a small command line application which integrates publicly accessible API’s from these service providers:
- Pressable - a managed WordPress host, part of the Automattic family
- GitHub - a well-known collaborative software development platform
- DeployHQ - a tool for managing software deployments
- Slack - an instant messaging and emoji proliferation platform
Here are the basic commands for our CLI tool:
create-development-site- Creates a new development site (on Pressable)
create-production-site- Creates a new production site (on Pressable).
create-repository- Creates a new GitHub repository in our GitHub organisation
create-development-site makes use of Pressable’s “site clone” feature and takes a Pressable
site-id as an input. The cloned site inherits the source site’s GitHub and DeployHQ setups. It is a more minor matter, but the jig also enforces our preferred site naming conventions- eg: development sites are named with the (production)
*.mystagingwebsite.com is a Pressable platform default).
create-production-site makes use of Pressable’s site provisioning API. It takes two arguments; a
sitename and a GitHub
reponame (scoped to our team’s GitHub organisation). Optional arguments include a GitHub repo, which when provided, configures DeployHQ so that merges to master are auto-deployed to the production site via SFTP.
create-repository uses the GitHub API to provision a new repository with scaffolding for things such as directory structure (eg: our repos are the
wp-content folder of the WordPress installation), issue templates, labels and more.
Provisioning repos and sites quickly and in a consistent manner from the command line alone may have been worth building the jig. However, the real value for us is creating sites and repos in a “workflow ready” state.
So, what does our “workflow ready” state look like?
It means that we have a WordPress site provisioned on Pressable, a code repository initialised on GitHub, Travis configured for CI, a DeployHQ project configured with our deploy strategy, and event logging flowing into Slack. With our jig, we can get to that “workflow ready” state in a single command:

Having the DeployHQ API at the center of our jig gives us flexibility and portability. If we ever need to integrate with a different source control platform or managed WordPress host, an update to our jig adding eg:
--wp-hosting-platform arguments along with a new DeployHQ project template is all it would take.
What I love about this jig is what I love about any jig, digital or physical- it makes completing an often repeated task more efficient and the outcomes more consistent.
So, what tasks do you or your team have which might benefit from building a jig? What jigs have you built?
If you’re able, share your jig on GitHub and add the “digital-jig” topic to your repo.
