# Edge overview

> A dark overview of a project on an edge network: KPIs with bar sparklines, live traffic on a dotted world map, an alert you can act on, latency and deployments.

The overview screen of a project served from ten regions. Requests travel the routes of a dotted world map while the regions’ traffic ticks; hover a region for its popover, or click it to filter the screen. One region runs slow since a deploy: shift 30% of its traffic to a neighbour and watch its dot, its row, the KPI and the chart come back down, then undo it, or open the slow request’s trace. Time ranges, a region menu, a line legend, search and Deploy all work.

## Anatomy

1. **Sidebar**: The team switcher, the sections with the open one marked, the projects (a red dot on one with an alert) and the month’s usage meter. An icon rail under 1100 px, a drawer under 720 px.
2. **Top bar**: Breadcrumbs, a search over regions and deployments that ⌘K focuses, and a bell with a dot while notifications are unread.
3. **Time range**: A radio group of four windows, beside the region menu and Deploy; it sets the KPIs, their bars and the latency chart.
4. **KPIs**: Four figures in one band (requests, p95, error rate, cache hits), each with its change and a 16-bar sparkline; red bars mark the slow hours.
5. **Traffic map**: A dotted world map with a button per region, its traffic on a chip and routes with travelling requests. The total ticks every 1.6 s while it is on screen.
6. **Alert**: The slow region written out, with Shift 30% to hkg1 (Undo once moved) and Open trace; the regions’ latency list sits under it.
7. **Latency chart**: p50, p95 and p99 over the range, a red band where p95 ran high, and deploy markers on the baseline. The legend switches lines; the arrow keys read values.
8. **Deployments**: The latest four, newest first: a status dot, the title, branch and commit, who and when. Deploy adds one that builds, then goes live.

## When to use

- The home screen of one service served from several regions: how much traffic, how fast, how many errors, and where.
- Health that differs by place, worth reading on a map: a region running slow stands out in red before any number is read.
- An alert the reader can act on from where it shows, with the action’s effect drawn back on every view (map, list, KPI, chart) and an Undo.
- Figures read over a few fixed windows (1h, 24h, 7d, 30d), where the range, a region filter and search narrow every card at once.
- A screen that has to keep moving while it is watched: live traffic ticking, requests travelling the routes, deploys going live.

## When not to use

- A service in one region. Drop the map: four KPIs, the latency chart and the deployments say it all.
- Digging into one incident. Use a trace or log explorer with spans, filters and a timeline; the trace here is a single request.
- Dozens of regions or points of presence. The map’s labels collide; use a sortable table, or a map with clustered markers.
- Business reporting (revenue, sign-ups, cohorts). Use a chart dashboard with a period picker and comparisons.
- A status page for customers. Use a list of components with their uptime and incidents, without controls.

## Installation

Install it with the shadcn CLI, into components/edge-overview of any React project:

```sh
npx shadcn@latest add https://brunodelorence.com/r/edge-overview.json
```

Or copy all the source files below into one folder of your project. Either way it needs React 19 and a bundler with CSS Modules (Next.js, Vite).

It has a dark colour scheme. Its colours are CSS light-dark() pairs, kept inside @supports so that builds which rewrite light-dark() for older browsers leave them alone: it follows your page’s color-scheme (light unless the page sets one) or its colorScheme prop, with nothing to configure. Browsers without light-dark() show it light.

## Usage

```tsx
import { EdgeOverview } from './edge-overview';

export function OverviewPage() {
  return (
    <EdgeOverview
      defaultRange="24h"
      defaultRegion="all"
      onShift={(shifted) => console.log(shifted ? 'shifted' : 'undone')}
      onDeploy={(deployment) => console.log(deployment.id)}
      autoplay={false}
    />
  );
}
```

## States

- **Overview**: The last 24 hours, every region, and the popover pinned on sin1, the region running slow.
- **Another range**: `defaultRange="7d"`: the KPIs, their bars and the chart change; the map and the regions do not.
- **One region**: `defaultRegion="sin1"`: the other regions dim on the map, the chart and the menu say sin1.
- **No popover**: `defaultPopover={null}`: the map opens with no popover until a region is hovered or focused.
- **Traffic shifted**: After Shift 30% to hkg1: sin1’s dot and row are back to normal, a route runs to hkg1, the alert offers Undo.
- **Trace open**: Open trace: the slow request’s five spans, the origin fetch in red. Escape closes it.
- **Reading the chart**: A crosshair in the red band with its values, p99 switched off in the legend.
- **Region menu**: Every region by city and code, the picked one checked; arrow keys, Home, End and Escape.
- **Notifications**: Three notifications; opening the menu clears the bell’s dot.
- **Team menu**: The team switcher’s menu, the current team checked, with its plan under it.
- **Search**: “hkg” in the search: the regions list and the deployments narrow, the map moves its focus to the match.
- **No matches**: A search that matches nothing: both lists say so.
- **Light**: `colorScheme="light"`, or a light page: every colour is a light-dark() token.
- **Dark**: `colorScheme="dark"`, or a dark page: the reference’s near-black window and cards.
- **Icon rail**: Under 1100 px of its own width: the sidebar keeps its icons, the KPIs go two by two, the map and the chart run full width.
- **Drawer**: Under 720 px a menu button slides the sidebar in over a scrim; the map and the chart scroll inside their cards.

## How it works

- The window is a two-column grid: a 231 px sidebar (team switcher, sections, projects and the month’s usage meter) and a main column whose cards sit on a named grid: title, KPIs, then the map beside the regions and the latency chart beside the deployments.
- The map is a 749 × 315 board scaled to fit its card. The land is a grid of dots, 4.35 px apart, kept where hand-drawn outlines of the continents say there is land, and painted on a canvas at the device’s pixel ratio. Each dot’s shade comes from its distance to the regions, weighted by their traffic; dots near an elevated region turn red.
- Routes are quadratic curves; the requests travelling them are small glowing dots on the same paths through CSS offset-path, so the motion costs no script. Each region is a button with its halo and label; hovering or focusing one opens its popover with its p95 over the last hours and its stats.
- The latency chart is drawn at the plot’s own pixel width, measured by a ResizeObserver, so strokes and dashes keep their weight. Inside the elevated band, p95 is drawn again in red over a red wash, clipped to the band; deploy markers stand on the baseline.
- Shift 30% to hkg1 plays a two-second eased change of one number, from which every view is derived: sin1’s traffic, latency and errors, hkg1’s traffic, the p95 KPI, the chart’s bump, the dot colours and a new route from sin1 to hkg1. Undo plays it back.
- Live, every 1.6 s the regions’ traffic moves a little: the total, the labels, the popover and the newest request bar follow. The stream and the moving requests stop offscreen, in a hidden tab and under reduced motion.
- Layout from the component’s own width: the reference’s two columns from 1400 px, one column of cards below, an icon rail for the sidebar under 1100 px and a drawer under 720 px, where the map and the chart scroll sideways inside their cards.
- While on screen and untouched, a demo pointer hovers regions, switches the range, reads the chart across the elevated band, opens the trace and shifts traffic, then undoes it. Any real input stops it.
- Every colour is a light-dark() token, so the screen follows the page’s color-scheme or the colorScheme prop; the canvas reads its colours through a probe and repaints when the scheme changes.

## API reference

- **defaultRange** (`'1h' | '24h' | '7d' | '30d'`, default `'24h'`): The time range at first: it sets the KPIs, their bars and the latency chart.
- **defaultRegion** (`'all' | 'iad1' | 'fra1' | 'sfo1' | 'lhr1' | 'hnd1' | 'sin1' | 'hkg1' | 'bom1' | 'gru1' | 'syd1'`, default `'all'`): The region filter at first; the chart follows it and the other regions dim on the map.
- **defaultPopover** (`RegionCode | null`, default `'sin1'`): The region whose popover is open at first. The map comes back to the elevated region when the pointer leaves it; null keeps it closed.
- **live** (`boolean`, default `true`): Whether traffic ticks and requests travel the routes (only on screen, never under reduced motion).
- **onRangeChange** (`(range: RangeId) => void`): Called with the range the reader picks.
- **onRegionChange** (`(region: RegionCode | 'all') => void`): Called with the region picked in the menu, on the map or in the list.
- **onShift** (`(shifted: boolean) => void`): Called when the alert’s action moves traffic (true) or undoes it (false).
- **onDeploy** (`(deployment: Deployment) => void`): Called with the new deployment when Deploy is pressed.
- **autoplay** (`boolean`, default `true`): While on screen and untouched, a demo pointer hovers regions, switches the range, reads the chart, opens the trace and shifts traffic. Any real input stops it.
- **colorScheme** (`'light' | 'dark' | 'system'`): Light or dark colours, or the reader’s; without it, the page’s color-scheme.
- **defaultState** (`EdgeOverviewState`): Opens in a state: { menu: "team" | "bell" | "region", trace, shifted, drawer, query, hidden: SeriesKey[], crosshair: 0–1, allRegions }. A menu opened this way leaves the focus alone; any of it turns the demo off.
- **className** (`string`): Classes for the root, the quiet field around the window.

## Accessibility

- Landmarks and headings: the sidebar is a labelled aside with a Sections nav (aria-current on the open one), the breadcrumbs are an ordered list, and every card is a section named by its heading.
- Each region on the map is a button named with its city, code, traffic, p95 and state; focusing it opens the same popover hovering does, and pressing it filters the screen (aria-pressed).
- The time range is a radio group with arrow keys; the team, region and notification menus are menus with arrow keys, Home, End and Escape, which hands the focus back to their button.
- The latency chart is an image with a summary, and takes the focus: Left and Right (Shift for bigger steps), Home and End move a crosshair whose values are read out. The legend entries are toggle buttons, and deploy markers are buttons.
- Cmd or Ctrl + K, while the focus is in the screen, goes to the search field; Escape clears it. The trace is a dialog that Escape closes, returning the focus to Open trace.
- A polite live region says when the range or region changes, when traffic is moved or moved back, and when a deployment builds and goes live. The ticking traffic is not announced.
- Colour is never the only signal: elevated regions say so in their names, the alert is written out, and the usage bar is a meter with its values. Moving requests, the halo pulse and the live dot stop under reduced motion; the demo pointer is hidden from assistive technology.

/*
 * Edge overview: the overview screen of a project on an edge network, dark first. An app window
 * with a sidebar (team switcher, sections, projects, the month's usage) and a main column: the
 * breadcrumbs, search and notifications; the project's title with its environment and address,
 * the time range, a region filter and Deploy; four KPIs with bar sparklines; traffic by region on
 * a dotted world map; the regions with an alert and their latency; the latency chart; and the
 * latest deployments.
 *
 * - Live: while the screen is on show, requests travel the map's routes, and every 1.6 s the
 *   regions' traffic, the total and the newest request bar move a little.
 * - Map: hovering or focusing a region opens its popover (p95 over the last hours, p95, requests,
 *   errors); clicking one filters the screen to it, as the region menu does.
 * - The alert: Shift 30% to hkg1 moves traffic over two seconds: sin1's latency, its dot on the
 *   map, its row, the KPI and the chart come back down, and a route from sin1 to hkg1 appears.
 *   Undo moves it back. Open trace shows the slow request's spans.
 * - 1h / 24h / 7d / 30d change the KPIs and the chart; the legend hides or shows each line;
 *   deploy markers on the chart are buttons. Search filters the regions and deployments.
 *   Deploy adds a deployment that builds, then goes live.
 * - Layout from its own width (container queries): the reference's two columns from 1400 px,
 *   one column of cards below; the sidebar is an icon rail under 1100 px and a drawer under
 *   720 px; the map and the chart scroll sideways inside their card on a phone.
 * - While on screen and untouched, a demo pointer hovers regions, switches the range, reads the
 *   chart, opens the trace and shifts traffic, then undoes it. Any real input hands it over.
 * - Light or dark: every colour is a light-dark() token, so the scheme is the page's
 *   color-scheme, or the one the colorScheme prop sets.

/*
 * The map of the Traffic by region card. Everything is laid out on a 749 × 315 board, which is
 * scaled to fit the card (never above its own size) and centred:
 *
 * - the land is a grid of dots on a canvas drawn at the device's pixel ratio. A dot's shade comes
 *   from how close it is to a region (weighted by that region's traffic), with a little steady
 *   noise, and dots around an elevated region turn red. It is drawn again only when the size or
 *   the regions' states change.
 * - the routes are quadratic curves in an SVG, and the requests travelling them are small glowing
 *   dots moved along the same paths by CSS offset-path, so the motion costs no script. They stop
 *   when the root says the screen is paused (offscreen, hidden tab, reduced motion).
 * - each region is a button: a dot with its halo and a label with its code and traffic. Hovering
 *   or focusing one opens the popover beside it, with its p95 over the last hours and its stats;
 *   leaving the map brings back the pinned region (the elevated one), if there is one.

### edge-overview/edge-overview.module.css

```css
/* Edge overview (edge-overview.tsx): an app window on a quiet field, with a sidebar and a main
   column of cards.

   Sizes are the screen's own px, measured on the reference at its true scale (the window is
   1445 × 903 there). The layout follows the component's own width (container queries on the
   root): two columns of cards from 1400 px, one below; the sidebar is an icon rail under 1100 px
   and a drawer under 720 px.

   Colours are the tokens below, light-dark(light, dark) where the two differ: the component takes
   the color-scheme it inherits from the page (light unless the page says otherwise), or the one
   its colorScheme prop sets (data-color-scheme).

   Motion is transforms and opacity: the requests on the map ride an offset-path, the bars grow
   by scaleY, the meters by scaleX. All of it pauses with data-paused on the root (offscreen,
   hidden tab, reduced motion). */
