Hub Portal

Jina Hub is a marketplace for Executors. Here you can upload the Executors you have created or use the ones already developed by the community. If it’s the first time you’ll develop your Executor you can start by checking our tutorials that will guide you through the process

Let’s see the Hub portal in detail

Catalog page

The main page contains a list of all Executors created by Jina developers all over the world. By default, you will see the Editors Pick first at the top of the list. Those are the Executors that were Highlighted by the Jina team.

You can sort the list of displayed Executors by Trending and Recent using the drop-down menu on the top. Otherwise, if you want to search for a specific Executor, you can use the search box on the top or use the tags for specific keywords such as Image, Video, TensorFlow, and so on:

Detail page

After you found an Executor that interests you, you can get more detail about it by clicking on it. You will then see a description of the Executor with basic information, usage, parameters, etc. If you need more in-depth details you can click on “More” and you will be directed to a new page with all information available about that Executor.

  1. README introduces basic information about this Executor, how it works internally, and its basic usage.

  2. Arguments describes the detailed API of this Executor. This is generated automatically from the Python docstrings of the Executor so it’s always in sync with the code base, and Executor developers don’t need to write it themselves.

  3. Tags will show you the possible tags available for this Executor. For example latest, latest-gpu and so on. It also gives a code snippet to simplify your usage.
