🤖 A robot (Claude Code) wrote this PR. The assignee directed the work.

Problem

  • Every dashboard downloads the add widget, subscriptions, sharing and Terraform export modals, which render closed but carry their editors and integration setup.

Refs #104853

Related: #110351, #110352, #110354, #110355, #110356

Changes

  • Each of the four modals loads lazily and mounts only while it is open. A modal can take a moment longer to appear the first time it opens.
  • useKeepMountedWhileOpen keeps each one mounted through its exit animation, as GlobalModals does.
  • The dashboard scene's ChunkLoadErrorBoundary is the nearest boundary, so a stale chunk reloads the page as it does for a scene.

Together the six PRs cut the dashboard scene from 11.66 to 9.62 MiB (−2.04 MiB), events from 10.89 to 9.23 MiB, replay detail from 13.77 to 12.06 MiB, and project home from 14.43 to 13.89 MiB (minified, linked stylesheet included, same master build). Several modules have more than one importer, so part of the saving appears only once all six land.

On its own this PR removes about 350 KB from the dashboard scene, and about 1 MB in combination with the others.

How did you test this code?

  • Typecheck passes, and the dashboard suites pass.
  • No story opens these modals through the dashboard route; their own stories render the components directly.
  • Not checked: opening each modal in a browser.

Test rationale: No new test. The modals keep their props and open state, and their own stories cover how they render.

Release status

  • No feature flag controls this change
  • This change is behind a feature flag and is not available to users
  • This change makes a previously flagged feature available to everyone

Created with PostHog Desktop

🤖 Generated with Claude Code

DashboardModals rendered the add widget, subscriptions, sharing and Terraform
export modals closed on every dashboard, so their editors and integration
setup sat on the dashboard scene's static graph. Each one is now a lazy
import that mounts only while open, and stays mounted through its exit
animation with useKeepMountedWhileOpen, as GlobalModals does.

✅ Trunk lane — non-backend lane

This PR is assigned to the non-backend lane. It does not run backend Python tests and may merge in parallel with PRs in other lanes.

⚠️ Complexity (TypeScript) — 1 function above the limit (max 24)

Cyclomatic complexity above the limit in changed typescript files (10 for production files, 15 for test files). Warn only: worth simplifying when you next touch these functions.

✅ Duplication (Python) — clean

New Python code duplication introduced by this branch. Fails at 70+ tokens in app code, or 150+ tokens when both copies live in test files. Advisory while the gate proves itself: extract a shared helper instead of copying.

⚠️ Comment density — 3% of added code lines are comments (5 of 149)

This section warns when comments are more than 3% of the code lines a PR adds, and alerts above 6%. Before agent-assisted PRs, the typical share was about 2%. Only full-line comments count. Docstrings, generated files, snapshots, migrations, and workflow files are left out.

Comments that restate the code, record how the change came about, or narrate the next line add noise for the next reader. Keep the comments that explain a reason the code cannot show, and remove the rest. See .agents/skills/writing-code-comments/SKILL.md for the house rules.

✅ Toolbar bundle — eager 2.19 MiB within budget

What the toolbar ships to customer pages, measured from the esbuild output (minified, post-tree-shake). The eager set is the entry plus everything statically imported from it — fetched before any feature runs; deferred chunks load lazily. The eager guardrail is 5.72 MiB. Each output file must also stay below 10 MB, where CloudFront stops compressing it. The module boundary is enforced separately by check-toolbar-graph.

📝 Walkthrough

Walkthrough

DashboardModals lazy-loads Add Widget, Sharing, Subscriptions, and Terraform Export with retry support. Each modal renders under Suspense with a delayed loading-modal fallback and remains mounted through its closing transition. Add Widget remains gated by the dashboard widgets setting. Sharing opens in Sharing mode.

Priority: ⬇️ Low

Merge Risk: 🔵 Low · up to 8c4e4

Screen-reader users may not be told that a dashboard modal is loading, though visual loading feedback and chunk-error recovery remain available. This is a bounded accessibility gap; the rest of the change appears mergeable with that limitation understood.

Security Architecture Review

Security architecture risk: ⚪ Minimal · up to 8c4e4

The reviewed changes defer existing dashboard dialogs without adding privileges or weakening their existing controls. Loading remains presentation-only, closing remains authoritative, and failed downloads use the existing recovery path.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The demonstrated change is confined to dashboard dialogs in the frontend session. The new fallback adds neither a data-store operation nor an independently privileged action; existing dashboard mutation and export paths retain their prior inputs.

Trust Boundaries and Controls

  • observed — Loading text is rendered as a React attribute, import destinations are fixed literals, and the fallback delegates closing to its caller. No dynamic import destination, credential handling, or new authorization decision appears in this entrypoint.

The lazy dashboard modals used a null Suspense fallback, so on a cold cache the
click that opened one had no visible response and nothing to close until the
chunk arrived. Each boundary now falls back to DashboardModalLoading, a spinner
modal that takes the real modal's open state and close action. It waits briefly
before it appears, so a cached chunk swaps straight to the real modal.

Risk: No findings

This increment adds an accessible loading announcement to the dashboard modal Suspense fallback: a static label prop rendered as role="status" with aria-label. It changes no security-relevant behavior; all labels are developer-authored constants, and the lazy-load gating and close handlers are unchanged.

Note

🤖 Automated comment by QA Swarm — not written by a human

Router pass over the full diff, then a second pass over the fix commits. No delegated lenses: danger graded LOW.

Verdict: ✅ APPROVE (@ eb87b76)

No findings. ReviewHog and Codex asked for loading feedback while a modal chunk downloads; fixed in eb87b76. Re-review confirmed closing during the load works through the useKeepMountedWhileOpen grace period. A NIT asking for a keep-mounted test was skipped: the hook is shared and used the same way in GlobalModals.

Checked against the lazy-load checklist from the #110093–#110095 reviews: lazyWithRetry for every dynamic import, a ChunkLoadErrorBoundary with a fallback inside query and card error boundaries, loading only on open or expand, no change to modal props or styles, and no imports left at moved paths.

This comment was marked as outdated.

The loading modal showed a bare spinner with no accessible name, so a screen
reader got no loading announcement while a modal chunk downloaded. It now wraps
the spinner in a role="status" region named from a label prop, defaulting to
"Loading". The file stays byte-identical to the copy in the sibling add-insight
PR, so the two still merge cleanly.

Approved.

Contained frontend performance change that lazy-loads four dashboard modals. It uses existing helpers (lazyWithRetry, useKeepMountedWhileOpen) and leaves modal props and open-state logic unchanged. Nothing falls in risky territory, and the reviewers' feedback was addressed with a loading fallback.
