Performance Analyzer
Spot bundle bloat, slow rendering paths, and inefficient code before your users feel it.
Overview
The Performance Analyzer examines your frontend and backend code to identify bottlenecks that slow down your application. It flags oversized JavaScript bundles, missing caching mechanisms, and inefficient database querying patterns. By catching these issues early, you can optimize your app's speed and responsiveness before users complain about slow load times.
N+1 Database Query in API Route
HighAn API route fetching a list of users also fetches their associated posts in a loop, resulting in an N+1 query problem that severely degrades performance as the user base grows.
Modify the ORM query to eagerly load relations using a JOIN or the appropriate eager-loading method provided by your database client.
How it works
Run the Performance Analyzer alongside your regular builds or before major traffic events. It helps you keep your bundle sizes in check and ensures your API endpoints remain highly performant as your feature set expands.
FAQ
> Can it test my live website's speed?
The Performance Analyzer relies on static analysis of your code to find structural performance flaws (like N+1 queries or unoptimized loops) rather than running dynamic load tests.
> Does it work for both frontend and backend code?
Yes, it checks both frontend frameworks (like React and Next.js) for bundle and rendering issues, and backend code for algorithmic and database inefficiencies.
