Coding Experience

This app was relatively simpler to build in comparison to the last one, because I had gained some experience in how to use databases in the last app.

This app was about finding the right libraries to get the job done.

For example, I was using the Google’s Image Search API to get the list of images. I used HTTPoison library for that.

Secondly, all the search terms are inserted in a database table named search_terms. So to get latest search terms, I had to write a postgreSQL query. I found many good examples here and was able to successfully write the query to retrieve the latest last 10 search terms.

Lastly, since I didn’t want all the information in search_terms table to be sent to the user. I had to pick certain properties from it and show only those. Thanks to stackoverflow I found a way to do so by overriding the default encoding of Phoenix.

Once I did that, the app was ready.

Thanks for reading. :)
