TL;DR I have already created services for the functions which bridges the module to the API, implementing the features offered by the Google Cloud Vision API, thus completing my first step towards Integrating Google Cloud Vision API to Drupal 8. This week I worked on generating error reports if the API key is not set by the user, and developing tests to test the API key configuration and whether the key is stored successfully or not.
The first step towards the integration of Google Cloud Vision API to Drupal 8 was completed with the functions moved to services. I had posted the patch for the review by my mentors. They provided their suggestions on the patch, which I worked on, and every step resulting in a better and more beautiful code.
I would also like to share that this week, our team expanded from a team of three, to a team of four members. Yes! Eugene Ilyin, the original maintainer of the module Google Vision API has joined us to mentor me through the project.
Now coming to the progress of the project, the schedule says I need to configure the Google Cloud Vision API at taxonomy field level, so that the end users may use the taxonomy terms to get the desired response from the API. However, the module already used the configuration for Label Detection, and in a discussion with my mentors, it was figured out that the current configuration does not need any changes, as at present the behaviour is pretty clear and obvious to let the developers use it easily; rather we should work on implementing the runtime verification and storage of API key supplied by the end users.
I was required to write and implement the code which would give error report if the API key was not saved prior to the use of the module, and also to write tests for verifying the configuration and ensuring the storage of the key.
I created issue for the new task, Implement a runtime requirement checking if API key is not set in the issue queues of the module, and started coding the requirement.
I created patches and posted it in the issue to get it reviewed by my mentors. I brought the suggested changes in the code and finally have submitted the patch implementing the required functionalities.
On the other hand, the previous issue Moving the common functions to services was also under the review process.
I also worked on this issue, solving and implementing minor suggestions before it gets ready to be accepted and committed! And finally, my first patch in this project has been accepted and the changes has been reflected in the module.
At the end of these two weeks, I learnt about services and dependency injection which prove to be very useful concepts implemented in Drupal 8. I also had experiences of writing tests to check the runtime functionality of the module.
