Publish your extension in the TER

Before publishing extension, think about

First of all ask yourself some questions before publishing or even putting some effort in coding:

  • What additional benefit does your extension have for the TYPO3 community?
  • Does your extension key describe the extension? See the extension key requirements.
  • Are there any extensions in the TER yet which have the same functionalities?
  • If yes, why do we need your one? Wouldn't it be an option to contribute to other extensions?
  • Did you read and understand the TYPO3 Extension Security Policy?
  • Does your extension include or need external libraries? Watch for the license! Learn more about the right licensing.
  • Do you have a public repository on e.g. GitHub, Gitlab or Bitbucket?
  • Do you have the resources to maintain this extension?
  • This means that you should

    • support users and integrators using your extension
    • review and test contributions
    • test your extension for new TYPO3 releases
    • provide and update a documentation for your extension

Use semantic versions

We would like you to stick to semantic versions.

Given a version number MAJOR.MINOR.PATCH, increment the:

  • MAJOR version when you make incompatible API changes (known as "breaking changes"),
  • MINOR version when you add functionality in a backwards-compatible manner, and
  • PATCH version when you make backwards-compatible bug fixes.

Additional labels for pre-release and build metadata are available as extensions to the MAJOR.MINOR.PATCH format.

Offer feedback options

Before you publish an extension you should be aware of what happens after it. Users and integrators will give you feedback (contributions, questions, bug reports). In this case you should have

  1. A possibility to get in contact with you (link to an issue tracker like forge, GitHub, etc.)
  2. A possibility to look into the code (link to a public repository)

You can edit these options in the extension key management (after login)

How to publish an extension

Now we come to the process of publishing in TER. You have two options for releasing an extension:

  1. Via the web form:

    Click "Upload" next to your extension key in the extension key management and follow the instructions.

  2. Via the REST interface (recommended):

    Use the PHP CLI application Tailor which lets you register new extension keys and helps you maintain your extensions, update extension information and publish new extension versions. For complete instructions and examples, see the official Tailor documentation.

    Besides manual publishing, Tailor is the perfect complement for automatic publishing via CI / CD pipelines. On the application's homepage you will find integration snippets and below recommended tools that further simplify the integration into common CI / CD pipelines:
