Web Operations
A practical playbook for zero-downtime deployments
How preview environments, automated checks and instant rollbacks take the risk out of shipping.

Start with preview environments
A preview environment is a full copy of the site built from a single branch. Reviewers click a link instead of reading a diff.
This removes the most common source of release surprises: nobody saw the change running before it went live.
Automate the checks people forget
Type checks, unit tests, accessibility scans and link checks run on every push. A failing check blocks the merge.
- Build and type check on every commit
- Smoke tests against the preview URL
- Performance budgets for key pages
Make rollback boring
Immutable deployments let you point production back at the previous build in seconds. Rehearse it quarterly so it is muscle memory.
