Overview
An environment per project, with pinned versions, is what stops "it worked yesterday" from being a real sentence.
In this lesson you will:
- Create and activate a per-project environment
- Pin dependencies so installs are repeatable
- Keep environment files under version control
Pro Tip
Use caching and revalidation wisely to ensure your app stays fast and data remains fresh without unnecessary requests.
