Performance Waterfall

Installation

A real shadcn registry command, not a copy-paste stand-in: it fetches this block plus its dependencies and any missing npm packages, and installs them straight into your project.

Prefer not to use the CLI? Copy the source from the Code toggle above into src/components/blocks/devtools/devtools5.tsx instead.

Usage

The file also exports devtools5Demo, the exact props behind the preview above. Spread it to get a working section in one line, then replace it with your own data.

import { Devtools5, devtools5Demo } from "@/components/blocks/devtools/devtools5";

export default function Page() {
  return <Devtools5 {...devtools5Demo} />;
}

Props

Types

type WaterfallRequest = {
  name: string;
  method: string;
  offsetPercent: number;
  durationPercent: number;
  durationMs: number;
};

Behavior notes

• Entirely static; no client-side interactivity, and no real network measurement. offsetPercent and durationPercent are fixed literals positioned with inline marginLeft/width styles against a fixed-width track.
• Bar color is derived from durationMs at render time (fast <100ms=emerald, medium 100-500ms=amber, slow >500ms=red) via plain arithmetic, not from a separate bucket prop, so color always stays in sync with the displayed duration.
• offsetPercent and durationPercent are independent of durationMs; the caller is responsible for keeping the visual bar roughly proportional to the numeric value, the component does not compute one from the other.
• The request name column has a fixed width and truncates long paths with an ellipsis rather than wrapping, to keep every bar's track aligned.
