Dynacover is a CLI application that dynamically generates Twitter header images showcasing your latest followers and/or GitHub Sponsors. This action runs Dynacover to update the Twitter header image of the account linked through the secret keys that must be previously defined as repository secrets.

Please refer to erikaheidi/dynacover for more details on how Dynacover works, what are the customization options, and how to create custom templates.

You'll need to set up your Twitter API credentials and user tokens using repository secrets, on the same repository you set up your action workflow. The GitHub token is optional, only required if you want to use one of the covers that showcase GitHub Sponsors.

Secrets

• DYNA_TWITTER_KEY: your Twitter application consumer key or App Key.
• DYNA_TWITTER_SECRET: your Twitter application consumer secret or App Secret.
• DYNA_TWITTER_TOKEN: your personal user token.
• DYNA_TWITTER_TOKEN_SECRET: your personal user token secret.
• DYNA_GITHUB_TOKEN (optional): your GitHub personal token (for pulling GitHub Sponsors).

For more information, check this tutorial.

You can fully customize the design of your banner. In order to do that, you'll need to include your custom template and any images you'll use in the repository where the workflow runs. This repository is checked out to a location that can be referenced from your workflow (check the example workflow for more info).

There are 3 environment variables you can use to set up the location of templates and images, and the default template:

• DYNA_TEMPLATES_DIR: path to the default location of templates in your workflow repository.
• DYNA_IMAGES_DIR: path to the default location of images referenced by your template, in your workflow repository.
• DYNA_DEFAULT_TEMPLATE: name of your custom template relative to DYNA_TEMPLATES_DIR.

For a real life example of how you can organize these files within your workflow, check the repository erikaheidi/github-actions where I have my own Dynacover set up.

Optional The template you want to use. Default is cover_basic.json.
