Preview Deployment
A live version of your app created automatically for every pull request or branch. It has a unique URL so your team can test changes before they merge to production.
ISR
Incremental Static Regeneration. Pages are built once and served as static files, then quietly rebuilt in the background on a schedule so content stays reasonably fresh.
Edge Network
A globally distributed group of servers. Each user's request is served from the nearest server instead of your origin, which cuts round-trip latency.
Cold Start
The delay when a serverless function starts up after being idle. It affects the first request after a quiet period but not subsequent ones.
Fluid Compute
A serverless model where multiple requests can share one running function instance. It cuts cold starts and costs on workloads that spend time waiting, like AI API calls.
Rollback
Instantly reverting production to a previous deployment without rebuilding. You restore the last working version in seconds, not minutes.
Observability
Logs, metrics, and traces that show how production AI behaves. You use them to debug failed rollouts and drift.
API Route
A server-side endpoint in your app that handles HTTP requests. You use API routes for form submissions, authentication, database calls, and webhooks.
Server Component
A component that runs on the server and sends HTML to the browser. It can fetch data directly without extra API calls or client-side loading states.
Environment Variable
A value stored outside your code, like an API key or database URL. Your code reads it at runtime so secrets never get committed to a repository.
Build Cache
Stored output from a previous build that can be reused in the next one. It skips re-installing unchanged dependencies so deploys finish faster.
Throttling
Limiting how often a function fires within a time window. Use throttling to prevent overloading a server or API with rapid repeat calls.
Debouncing
Delaying a function until after a rapid action stops, like typing. It runs once after the action settles, not once per event.
