This is common for redirects and error responses not meant for this page template.</li> </ul> <p><strong>Brian #2:</strong> <a href="https://adamj.eu/tech/2020/10/15/a-single-file-rest-api-in-django/"><strong>Django REST API in a single file, without using DRF</strong></a></p> <ul> <li>Adam Johnson <ul> <li>He’s been on Test &amp; Code a couple times, <a href="https://testandcode.com/128">128</a> &amp; <a href="https://testandcode.com/135">135</a></li> </ul></li> <li>Not sure if you should do this, but it is possible.</li> <li>Example Django app that is a REST API that gives you information about characters from Rick &amp; Morty.

Hardcoded here, but easy to see how you could get this data from a database or other part of your system.</li> </ul> <p><strong>Michael #3:</strong> <a href="https://insights.stackoverflow.com/survey/2020"><strong>2020 StackOverflow survey results</strong></a></p> <ul> <li>Most Popular Technologies</li> <li>Languages: JavaScript (68%), Python (44%), Java(40%)</li> <li>Web frameworks: Just broken, jQuery?
