• The dashboard shows a lot of information and allows a variety of actions – this made it crucial to design the application focusing on the user experience.  I worked with various aspects of a front-end framework (Bootstrap here) and came across the ease of basic styling of HTML elements such as forms, tables, buttons, icons, etc. and the most useful – Bootstrap modal. Bootstrap provided with a consistent theme for the dashboard with good documentation. It now keeps the scope to leverage the grid system to allow development of a mobile-first application.
• Running codebase in different environments is always a great learning. Working with the file-download feature I learned that a given request on the web worker may only last 30 seconds on Heroku (our production environment) and will be killed after that period. Since creating a zip file can easily take longer, we did some brainstorming and decided to keep the network calls out of the request-response cycle by creating a celery worker task to do the downloading job. Working with celery worker tasks and Redis broker was a new and enriching experience for me.
• To allow OH-run version and allow developers to run a version themselves as well, we weighed in two options to store the downloaded files – AWS S3 and transfer.sh wherein we settled on the first option given the 10GB limit on the latter.
• Since the downloading of files happened as a background job, the user could be notified of the completion of file download either through a dashboard notification or via an email. We decided to go ahead by emailing the user (easy peasy) by setting up a configurable SMTP server in Django.

The work done so far has been rewarding in terms of experience with Django, Bootstrap and various other modules. More development calls for more feedback and hence, more iterations. Therefore, I’ll be working on making some modifications to the UI and features incorporating the feedback.

More Tango with Django ahead 😀 Cheers!
