When we create projects using an environment (with multiple packages managed by npm, and webpack to bundle our source code), we'll often start with the exact same files. It can be tedious to build all of these files from scratch, especially when we're building new projects every day.
Fortunately, we can create template repositories in GitHub which we can reuse (and modify) for future projects. In this lesson, we'll learn how to create a template repository in GitHub as well as how to use the template for other repositories.
First, we need to create a repository that includes all the files we want. We'll keep this example simple. It will include just a README. On your computer, go ahead and create a directory called
template-repo which includes the following
# (Application Name) #### (Brief Description of Application) #### By (Your Name Here) ## Technologies Used * _List all_ * _the major technologies_ * _you used in your project_ * _here_ ## Description ## Setup/Installation Requirements * _This is a great place_ * _to list setup instructions_ * _in a simple_ * _easy-to-understand_ * _format_ ## Known Bugs * _Any known issues_ * _should go here_ ## License
As we can see, this README contains headers for all of the items that are required in the READMEs for projects we create at Epicodus.
The next step is to commit the code, create a GitHub repo, and push your local code to the remote repo. Once that's finished, go to the repository in GitHub and click on Settings.
As the image above shows, once you click on Settings, you can click the checkbox marked Template repository. A little green checkmark will pop up by the box, which means that GitHub has auto-saved the update.
After checking the box, navigate back to the main page of the repository. You'll see it has a Template label by the name of the repository:
If there's not a Template label, you'll need to go back to the Settings and make sure you checked the box.
You'll also see that the repository now has a green Use This Template button.
If we want to create a new repository using this template, we just need to click the Use This Template button. We'll be taken to a page for creating a new repository. It looks almost exactly the same as the new repository page we've been using so far. The only difference is that we are now creating the repository from a template. We can create the repository as usual, but this time once the repository is created, all of the files from the template will be included in the new repository. Finally, we can clone the repository to our desktop and modify it as needed, changing the README or any other files it already has such as configuration or code files.
Using a template repository is especially helpful for projects that include boilerplate environments such as the ones we've been building in this section. We can easily create a template repository that includes a
package.json file, a webpack configuration, and any other configuration files such as what we might need for Babel or ESLint.
You can base your template off of the Shape Tracker repo (linked below) or a project you created in this course section. If you decide to use the Shape Tracker project repo, make sure to use the branch titled
3_multiple_business_logic_files as your point of reference. As needed, review the lesson on accessing code from different branches.
Your template repo should have the following files copied over from your reference project:
You can also include directories such as
src/js, though you'll need a file in any directory for Git to be able to track it.
You can also optionally include boilerplate code such as the structure for Jest tests.
When you create your template repository, take the time to add thorough installation/setup instructions to your README. This should include information on how to run the project:
$ npm install.
$ npm run build
$ npm run start
$ npm run lint
$ npm run test
Also, make sure you update the Technologies Used section of your README, too! There's been a host of new tech that we've used in our projects in this course section.
Template repositories can make it much easier to get started on a project. To really utilize a template repository effectively, you need to get it right. That's why it's worth taking a little extra time to put together a great template README now. If the README in the template repository is mediocre, chances are it will lead to mediocre READMEs in other projects, too, and a lot of additional work to get those READMEs in shape later down the road.
One final recommendation — while we do recommend getting specific about details such as installation steps, you don't want to make your templates so specific that they aren't reusable. If you find yourself regularly deleting content from repositories that have been built from a template, that's a sign that the content in the template isn't serving its purpose; you want to minimize the amount of boilerplate you need to add from scratch, but you also want to avoid having to delete a lot of boilerplate, too.
