# Templates

A template is a pre-made Strapi configuration designed for a specific use case. It allows you to quickly boostrap a custom Strapi app.

Here are some things a template may configure for you:

  • Collection types and single types
  • Components and dynamic zones
  • Plugins to install, or custom plugins

WARNING

Templates and starters are not the same thing:

  • A template is a pre-made Strapi configuration. Note that it's only a configuration, not a configured application. That's because it cannot be run on its own, since it lacks many files, like database configs or the package.json. A template is only useful once applied on top of a default Strapi app via the CLI.
  • A starter is a pre-made frontend application that consumes a Strapi API

# Using a template

You can use a template when creating a project with create-strapi-app.

You can use the --template option in combination with all other create-strapi-app options, like --quickstart or --no-run.

# Creating a template

To create a Strapi template, you need to publish a public GitHub repository that follows some rules.

First, a template's only concern should be to adapt Strapi to a use case. It should not deal with environment-specific configs, like databases, or upload and email providers. This is to make sure that templates stay maintainable, and to avoid conflicts with other CLI options like --quickstart.

Second, a template must follow the following file structure.

# File structure

You can add as many files as you want to the root of your template repository. But it must at least have a template.json file and a template directory.

The template.json is used to extend the Strapi app's default package.json. You can put all the properties that should overwrite the default package.json in a root package property. For example, a template.json might look like this:

{
  "package": {
    "dependencies": {
      "strapi-plugin-graphql": "latest"
    },
    "scripts": {
      "custom": "node ./scripts/custom.js"
    }
  }
}

The template directory is where you can extend the file contents of a Strapi project. All the children are optional, you should only include the files that will overwrite the default Strapi app.

Only the following contents are allowed inside the template directory:

  • README.md: the readme of an app made with this template
  • .env.example: to specify required environment variables
  • api/: for collections and single types
  • components/ for components
  • config/ can only include the functions directory (things like bootstrap.js or 404.js), because other config files are environment-specific.
  • data/ to store the data imported by a seed script
  • plugins/ for custom Strapi plugins
  • public/ to serve files
  • scripts/ for custom scripts

If any unexpected file or directory is found, the installation will crash.

# Step by step

After reading the above rules, follow these steps to create your template:

  1. Create a standard Strapi app with create-strapi-app, using the --quickstart option.
  2. Customize your app to match the needs of your use case.
  3. Outside of Strapi, create a new directory for your template.
  4. Create a template.json file in your template directory.
  5. If you have modified your app's package.json, include these changes (and only these changes) in template.json in a package property. Otherwise, leave it as an empty object.
  6. Create a /template subdirectory.
  7. Think of all the files you have modified in your app, and copy them to the /template directory
  8. Publish the root template project on GitHub. Make sure that the repository is public, and that the code is on the master branch.
