-name: storybook-visual-diff
-description: Screenshot a set of SigNoz Storybook stories, then pixel-diff two runs to see what a CSS or component change did, with the changes tinted over the new shot. Use when asked to take story screenshots, capture a visual baseline, compare before/after of a style change, or find which pages a change affects.
----
-
-# Storybook visual diff
-
-Two scripts under `frontend/scripts`:
-
-- `story-shots.mjs` — screenshots stories off a running Storybook dev server.
-- `story-shots-diff.mjs` — pixel-diffs two runs and paints what moved.
-
-Output goes to `frontend/.story-shots/` (gitignored), one directory per run.
-
-## 0. Settle what is being compared, first
-
-A diff is only worth taking when the two runs straddle something. Run twice over
-the same tree and the answer is zero, or the noise floor: true, and useless.
-So before starting a server, pin down four things. Whatever the prompt already
-says, take it and do not ask again; ask only for what is genuinely missing, in
-**one** `AskUserQuestion` call.
-
-| To settle | Ask | Options |
-| --- | --- | --- |
-| Job | "What should this run produce?" | shoot only · baseline for a change you are about to make · compare against a change already in the working tree · compare this branch against another (`main` by default, or one the user names) · compare two configurations of the same story (`--args`, clock, width) · noise floor (same tree twice) |
-| Scope | "Which stories?" | offer 2-3 concrete selections read off `index.json` (a page, a `--title` prefix, everything), never open-ended |
-| Themes | "Which themes?" | dark · dark + light |
-| Read-out | "How should the diff read?" | `green` (changed pixels over the after shot) · `green-parallel` (before \| after \| diff, side by side) · `red` · `red-parallel` · `none` (keep both runs, do not diff) |
-
-Skip a row when the prompt answers it, and skip the whole call when the prompt
-answers all of it ("shoot the pods tooltips in both themes" needs no question).
-Skip Read-out too whenever the job is *shoot only*, and take `none` for what it
-says: shoot both sides, report both paths, run no comparison. When the prompt
-says nothing at all, ask; a silent guess here burns ~6 min per sweep on the
-wrong stories.
-
-The job decides which loop below to run:
-
-| Job | Loop |
-| --- | --- |
-| **shoot only** | §1, §2, stop. Report the paths. No diff, no second run. |
-| **baseline first** | the full loop, stopping after step 2 to hand the change back. The user makes it, then continue at step 4. |
-| **change already in the tree** | the tree *is* the after state. `git stash` (or check out the base commit) to shoot the before, restore, shoot the after. Confirm the working tree is clean enough to stash before touching it, and restore it even if a capture fails. |
-| **branch vs branch** | shoot the current branch, then `git switch <base>` in place (stash first if the tree is dirty), restart the dev server, shoot again, switch back and unstash. Restart matters: HMR does not survive a whole-branch swap cleanly. Get the tree back to where it started even if a capture fails. |
-| **noise floor** | two runs, same tree, diff. The number is the harness's floor, not a finding. |
-| **config vs config** | same tree, two runs that differ only in flags: `--args`, `--clock`, `--width`, `--theme`, `--motion`. Filenames stay identical, so the pairs line up and the caption names what changed. |
-
-## The loop
-
-1. Capture the baseline **before touching anything**.
-2. Capture it a second time and diff the two. That is the noise floor: anything
-   it reports is what the harness cannot hold still, and no conclusion about the
-   change may rest on those stories. Cheap on a handful of stories, ~6 min per
-   32, so on a wide sweep run it over the two or three stories the change is
-   aimed at instead of all of them.
-3. Make the change.
-4. Capture again into a third directory.
-5. Diff, then read the tinted shot of the largest movers to judge the change.
-
-## 1. One dev server, on a free port
-
-`storybook dev` keys its Vite dep cache off the config dir, so two servers on the
-same `-c` serve mismatched prebundles and every story dies with `Invalid hook
-call`. Check what is already up first — port 6006 is often another repo's
-Storybook, and its `index.json` then indexes the wrong stories:
-
-```bash
-for port in 6006 6007; do
-  curl -s -m 2 "http://localhost:$port/index.json" | head -c 60 && echo "  <- $port"
-done
-```
-
-Start the SigNoz one on a free port, from the repo's own binary so no package
-manager shim is in the way:
-
-```bash
-cd frontend
-nohup ./node_modules/.bin/storybook dev -p 6007 --no-open --quiet \
-  > "${TMPDIR:-/tmp}/signoz-storybook.log" 2>&1 &
-```
-
-It is ready when `curl -s localhost:6007/index.json` returns JSON whose
-`entries` hold SigNoz story ids.
-
-## 2. Capture
-
-Playwright is not a frontend dependency. The script finds it in `tests/e2e`
-(`pnpm -C tests/e2e install`, `@playwright/test` is enough) or in a global
-install, and launches Playwright's own chromium, falling back to an installed
-Chrome. Two escape hatches when that is not what a machine has:
-
-```bash
-export PLAYWRIGHT_MODULE=/path/to/playwright   # a different install
-export CHROME_PATH=/path/to/chrome             # a specific browser binary
-```
-
-Then pick the stories. `--list` prints the selection without shooting anything:
-
-```bash
-# every tooltip story of every page
-node scripts/story-shots.mjs .story-shots/baseline \
-  --port 6007 --title Pages/ --name tooltip --theme dark
-
-# a handful of stories by id or by title/name substring, both themes
-node scripts/story-shots.mjs .story-shots/baseline \
-  --port 6007 --stories pages-noz,dashboards/detail --theme dark,light
-```
-
-| Flag | Meaning |
-| --- | --- |
-| `--stories <match>` | id or `Title/Name` substring, repeatable or comma-separated. Omit for every story. |
-| `--title <prefix>` | only titles starting with the prefix (`Pages/`, `Components/`) |
-| `--name <match>` | only story names containing the match |
-| `--theme dark,light` | one pass per theme; omit for the story's own default (dark) |
-| `--args <k:v;k2:v2>` | arg overrides, Storybook's own `?args=` syntax, repeatable. A dotted value is dropped by Storybook itself, so map it to a slug inside the story's mocks |
-| `--port` | dev server port, or `$SB_PORT` |
-| `--width <px>` | the only fixed dimension, default 1680 |
-| `--height <px>` | shortest the viewport may be, default 1200 |
-| `--max-height <px>` | tallest it may grow to, default 8000 |
-| `--grow <what>` | `scrollers` (default) grows the viewport until the page's own scrollers fit, `document` only follows the document height, `none` keeps `--height` |
-| `--settle <ms>` | wait after the page goes quiet, default 1500 |
-| `--clock <iso\|live>` | wall clock the page reads, passed to the preview as `?storyClock`; `live` unfreezes it |
-| `--motion` | keep animations and transitions running (sets the `motion` global to `live`) |
-| `--ignore <selector>` | hide matching elements, on top of `[data-shot-ignore]` and `[data-chromatic="ignore"]` |
-| `--flat` | write `<out>/<id>.png`, no theme directory |
-| `--no-caption` | leave the caption band off the shots |
-| `--list` | print the matched stories and exit |
-
-Files land at `<out>/<theme>/<story-id>.png`, next to a `shots.json` recording
-what each shot is (id, title, name, theme, `ok`/`busy`, the caption's height in
-rows) and how the run was configured (args, clock, width, height, grow, motion,
-settle, ignore). Keep the flags identical between the two runs or the diff pairs
-nothing.
-
-Every shot carries the caption band described below, so a single screenshot says
-what it is on its own. `--no-caption` leaves it off, and so does a machine
-without ImageMagick (with a warning). The band never changes the shot's width
-(long text wraps rather than widening the canvas) and its height is recorded, so
-the diff crops it back off and never reports one caption against another. Two
-runs whose captions are different heights still diff to zero. A story that never held still for two
-identical frames is logged `busy` instead of `ok` — treat its diff as suspect.
-
-Dark alone is enough while iterating on the harness; add `light` for the run you
-report.
-
-## 3. Diff
-
-```bash
-node scripts/story-shots-diff.mjs .story-shots/baseline .story-shots/capped .story-shots/diff
-```
-
-Prints `<changed pixels>  <theme>/<story>.png`, largest first, and writes one
-image per pair. Needs ImageMagick for PNG encode/decode (7's `magick`, or 6's
-`convert`/`identify`/`montage`); the comparison itself is in the script.
-
-| Flag | Meaning |
-| --- | --- |
-| `--mode green` | default. The after shot with the changed pixels painted over it, exactly the pixels that changed. What Chromatic shows. |
-| `--mode green-parallel` | `previous \| current \| diff` in one image, each tile labelled above it, on a gutter inverted from the theme. The diff tile is the `green` one, so the after shot stays readable underneath. |
-| `--mode red` | the after shot faded to 10%, changed pixels in red. A pixelmatch-style diff, easiest to read when the change is a thin edge. |
-| `--mode red-parallel` | the same three tiles, with the `red` diff. Best when the change is a thin edge that the unfaded shot would swallow. |
-| `--threshold <0..1>` | how far a pixel must move to count. Default 0.063, Chromatic's `diffThreshold`. |
-| `--include-aa` | count antialiasing changes too. Off by default, as in Chromatic. |
-| `--tint <#rrggbb>` | override the mode's colour. |
-| `--no-caption` | drop the caption band. |
-
-### The caption
-
-Both scripts stamp a band on top of what they write: `story-shots.mjs` on each
-shot, from the story and the run's own settings; `story-shots-diff.mjs` on each
-diff, read out of the two runs' `shots.json`. It carries the story's
-`Title/Name`, then its id, theme and `busy` flag, then the settings both runs
-shared, each reading `key:value`. Whatever the two runs did **differently** goes
-on the side it belongs to: under `previous` and `current` on the parallel tiles,
-on two lines of the band otherwise. So a pair that differs only in `--args` says
-so on its face, which is what makes several shots of one story tellable apart.
-
-The shots' own bands are cropped off before comparing and before going into the
-tiles, so nothing in the output is a diff of a caption. Type size follows the
-image width, so it stays readable with the whole image viewed at fit-to-width;
-the heading is set in an installed sans and the detail lines in a mono, falling
-back to ImageMagick's default when neither is on the machine. Without a manifest
-the band falls back to the file path, and a directory of captioned shots whose
-`shots.json` is missing has nothing to crop by, so its captions do land in the
-diff. Keep `shots.json` next to the shots.
-
-### How the comparison works
-
-Chromatic's own capture and diff run server-side — `chromatic-cli` uploads a
-built Storybook and contains no capture or comparison code at all. What is public
-is the parameter contract, and the numbers in it say what the comparison is:
-`diffThreshold` defaults to `0.063` on a 0-1 scale, which is pixelmatch's
-`threshold`, and `diffIncludeAntiAliasing` defaults to false, which is
-pixelmatch's `includeAA: false`. So the script implements that comparison:
-
-1. Both PNGs are read as raw RGBA through `magick … RGBA:-`.
-2. Per pixel, the squared YIQ distance between the two colours (weights
-   `0.5053 / 0.299 / 0.1957`), compared against `35215 * threshold²` — 35215 is
-   the largest distance two 8-bit colours can have. Chroma is included, so a
-   colour swap at equal brightness still counts.
-3. A pixel over the threshold is dropped when it is only antialiasing: it is the
-   darkest or lightest of its eight neighbours, and the other image has a pixel
-   around there doing the same job. This is what keeps a subpixel glyph edge from
-   reading as a change.
-4. What survives is painted at full opacity, one output pixel per changed input
-   pixel. No dilation, no blobs — a one-pixel shift shows as a one-pixel line.
-
-A pair whose shots are different sizes is compared over the overlap, and every
-row and column that exists in only one of them counts as changed.
-
-Pairing is by `<theme>/<story-id>.png`, so a story that exists on only one side
-(new on the feature branch, renamed, retitled) has nothing to pair with and is
-skipped silently. On a branch-vs-branch run, compare the two runs' file lists
-before reading the numbers.
-
-## What makes a shot reproducible
-
-Most of it is in the preview, not in the script, so a Chromatic build in the
-cloud shoots the same page: `.storybook/preview-head.html` freezes the clock,
-and `settleForCapture` (the preview's `afterEach`, which runs after `play`)
-parks the animations and snaps the bottom-pinned lists. The script drives the
-rest:
-
-- **Storybook's own render phase is the readiness signal.** It waits for
-  `window.__STORYBOOK_PREVIEW__.storyRenders[].phase === 'finished'`, which is
-  reached only after the loaders, the decorators and the story's `play` are done.
-  A DOM check cannot see a `play` still running. (Storybook 10 spells the final
-  phase `finished`, not `completed`.)
-- **Network quiescence, not `networkidle`.** react-query retries and msw keep
-  requests going after load, and a few stories hang a request by design, so the
-  wait is "no request for 600ms", capped at 15s.
-- **The clock is frozen** (`2026-06-15T12:00:00Z`), by the preview itself. Chart windows, `4 mins ago`
-  labels and trial countdowns all derive from `now`; a live clock alone moved
-  8000 pixels on the dashboards list and redrew every chart axis.
-- **Animations are parked on their last frame** by `html.sb-still`, a
-  zero-length single iteration with `forwards` fill, plus `prefers-reduced-
-  motion`. The Motion toolbar item (`still` by default) turns it off. An infinite
-  spinner is otherwise caught at a random angle.
-- **`document.fonts.ready`**, because text reflows when a face lands late.
-- **Lists pinned to their bottom are snapped onto it**, once by the preview and
-  again by the script after the page goes quiet. A virtuoso list settles a
-  few pixels short of the end depending on the order its items were measured in.
-- **Two identical frames in a row**, because what a page is still waiting on is
-  often not observable from outside it.
-- **`[data-shot-ignore]`, `[data-chromatic="ignore"]` and `--ignore <selector>`**
-  hide a region that cannot be held still; Chromatic excludes the same attribute
-  from its comparison.
-- **The width is the only fixed dimension.** Chromatic's `viewports` are widths;
-  the height follows the page. `src/styles.scss` pins `html, body, #root` to
-  `height: 100%; overflow: hidden`, so the document never outgrows the viewport
-  and its height says nothing: what overflows are the shell's inner scrollers.
-  `--grow scrollers`, the default, grows the viewport until the tallest in-flow
-  scroller fits, so nothing is cut off and no scrollbar is left in the shot (the
-  dashboards list goes to 2226px in one round). Popups are skipped — they are out
-  of the flow, and a tall dropdown would otherwise drag the shot to a height
-  nothing on the page needs. A page that sizes a panel in `vh` grows its own
-  content as the viewport grows, so no height ever fits it and the rounds only
-  chase — `.alert-chart-container` is `57vh`, which puts Create Alert's fixed
-  point at 4344px with an empty band on top. Those pages are shot at `--height`
-  with their own scrollbar, which is what they look like in a browser, and the
-  log says `(viewport-sized content, stopped chasing Npx)`.
-
-With all of that, 29 of the 32 page tooltip stories are byte-identical across
-runs. The three that are not, and why:
-
-| Story | Residual | Cause |
-| --- | --- | --- |
-| `kubernetes-pods--tooltips-in-options-panel` | ~13k px | 24 tooltips held open in an overlapping cluster; they portal to `body` in mount order, and the drawer's own tooltips mount before or after the list's depending on when their data lands, so overlapping tooltips stack differently. Panel geometry itself is stable. |
-| `settings-role-editor--tooltips-in-json-editor` | ~2.5k px | monaco re-measures and lands one pixel off. |
-| `traces-trace-details--tooltips` | ~800 px | same class, one row of the waterfall. |
-
-Each is bimodal — two stable arrangements — so the same number reappears run
-after run. Diff a story against itself before believing its number, and reach
-for `--ignore` when a region cannot be settled.
-
-## Gotchas
-
-- **Zero pixels is a real answer.** A story whose tooltips are all short is
-  unaffected by a tooltip rule; it is not a broken capture.
-- **The selector matters more than the rule.** A global rule on
-  `[data-slot='…']` only reaches design-system components. antd's own tooltips
-  (`.ant-tooltip-inner`, e.g. the Create Alert help popups) are untouched, which
-  is why some stories show no diff at all.
-- **Global style overrides need `!important`.** `src/styles.scss` loads before
-  the design system injects its CSS-module styles at runtime, so a plain rule on
-  a `[data-slot='…']` element loses. A component-level `!important` of the same
-  specificity still wins over it — `PanelStatusPopover.module.scss` keeps its own
-  `max-width: 520px !important`.
-- **A fresh context per story** is why a full sweep takes ~6 min for 32 stories.
-  Reusing one page loses the msw service worker re-registration race and stories
-  start failing after a few navigations.
-- **Stories behind a hover, drawer or modal** only render what their `play`
-  reaches. If a state is missing from the shot, the story needs the `play`, not
-  the script.
