111: Deploying a PR for Review

ThinkingElixir.com — Tue, 09 Aug 2022 04:15:00 -0600

Ever wanted to deploy a PR to a temporary server for show-and-tell, QA testing, or to get feedback on it? Jason Axelson joins us to share how he did that on Render.com. We explore how it can be done on other platforms like Fly.io as well. We talk about how this ability benefits teams and companies. We dig into how setting up a seeded DB for the code isolates data changes but also makes it easier for people to test the code with multiple data scenarios. Turns out doing this may be easier than I thought!
