refactor(email): render existing templates with Svelte 5 by niemyjski · Pull Request #2258 · exceptionless/Exceptionless

niemyjski · 2026-05-27T14:07:35Z

Summary

Replaces the retired Foundation/Gulp email build with Svelte 5 while preserving the existing nine production emails exactly. This is now the renderer-only third PR in a reviewable stack:

test(mail): characterize production email contracts #2526 characterizes the existing email contracts.
fix(mail): safely render event links and regression labels #2527 fixes mailto encoding and the existing regression label.
This PR changes only how those templates are authored and generated.

The invitation/login behavior audit is independent in #2528.

What changed

Moved the email sources into src/Exceptionless.Web/ClientApp/emails so the web app and email renderer share one Svelte/Vite/TypeScript toolchain and lockfile.
Kept email generation as an explicit build:emails target because it produces server-rendered HTML rather than the browser application.
Removed the standalone email package, old Foundation/Gulp sources, duplicate dependency configuration, and duplicate CI job.
Auto-discovers the Svelte templates and fails unless exactly nine same-named production HTML files exist.
Replaced synchronous child-process execution and main().catch(...) with an async Vite hook and top-level await; the build targets Node 24, matching CI.
Reduced EmailLayout.svelte to shared document/layout rules. Event, daily-summary, action-footer, and social-footer styles now live with their owners.
Preserved the established email palette, content, Handlebars behavior, URLs, JSON-LD, conditional output, and rendered pixels.
Kept Storybook out of Aspire and added no Storybook/email integration.

Intentional compatibility details

UserEmailHref comes from fix(mail): safely render event links and regression labels #2527. It is not a Svelte requirement; C# constructs and percent-encodes the mailto: URI so user text cannot inject another mail parameter.
Renderer cleanup removes only the four currently emitted Svelte SSR markers and Better Svelte Email's default target="_blank". It does not collapse whitespace, minify HTML, strip arbitrary comments, or parse/rewrite JSON-LD.
The social footer uses 50/50 columns. Its documented 0.375px desktop correction preserves the old Foundation table rounding; all mobile rules remain component-owned.
Better Svelte Email is pinned to the current 2.1.3 release. deepmerge-ts is overridden to the newest security-fixed release eligible under the repository age policy (8.0.1), removing the two high-severity audit findings introduced by html-to-text.

Scope deliberately excluded

invitation/authentication behavior (now fix(auth): preserve organization invitations through login #2528)
route migration to next-generation Svelte URLs
Storybook/Aspire changes
checked-in legacy baselines, parity galleries, screenshots, or duplicate template copies
unrelated ClientApp dependency upgrades

Verification

npm ci
npm run build — web application plus 9/9 email templates
generated-output drift check — clean
npm run check — 0 errors, 0 warnings
npm run lint — passed
focused mailer tests — 29 passed
semantic parity — exact visible text and ordered actions in 13 representative scenarios
pixel parity — 26/26 exact comparisons across desktop and mobile
npm audit — 0 high/critical findings; 7 pre-existing low findings remain
full ClientApp unit suite — 699 passed; one unrelated, unchanged navigation-command test fails identically when rerun in isolation (/next/stack expected, /next/ received)

Breaking changes

None intended. Template filenames, rendered content, public URLs, and C# Handlebars contracts remain backward-compatible.

Post-Deploy Monitoring & Validation

Confirm the first production build reports nine generated email templates and no generated-file drift.
Send representative event, organization, billing, daily-summary, verification, and password-reset emails through the normal non-production mail path.
Verify links and JSON-LD actions resolve to the same destinations characterized in test(mail): characterize production email contracts #2526.
Watch mail rendering/error telemetry for unresolved Handlebars tokens or missing-template failures after deployment.

✅ Rendering Bug Fixes — Verified

Latest commit (b5cd6e6) fixes all rendering/formatting issues found in review:

Fixed Issues

Issue	Root Cause	Fix
All `{{#if}}` branches showing simultaneously	`fillTokens` used regex (couldn't track nesting)	Rewrote as character-by-character evaluator with depth tracking
Extra `<hr>` before first error field	`{{#if @index}}` — was always truthy with naive regex	`isTruthy('0')` returns false; first item correctly skips divider
"fromwhich" word concatenation	`cleanHtml` removed all newlines incl. text node linebreaks	Replace `\n` → `' '` (space) not `''`
"to to continue/see" double word	Typo in template source	Fixed in `organization-notice.svelte`
"?Exceptionless" missing space	Same whitespace collapse issue	Fixed by cleanHtml fix + single-line in template

Screenshots (after fixes, with realistic sample data)

Event Notice — single clean message, no branch concatenation, no extra HR before first field
Password Reset — "from which" correct spacing
Organization Notice — "to continue", "to see" correct
Organization Invited — "? Exceptionless" with proper space
Daily Summary — MostFrequent + Newest lists, [REGRESSED] badge

Dogfood Evidence — Mailpit Email Renders

All 8 templates sent to Mailpit via SMTP and visually verified. HTML Check scores range 87–94%.

Bug Found & Fixed: `IsRegressed` badge was never rendering

Root cause: GetStackTemplateData() in Mailer.cs returned the stack data without IsRegressed, so {{#if IsRegressed}}[REGRESSED]{{/if}} always evaluated false. The badge silently never appeared for regressed stacks — in main or in this PR until caught.

Fix: Added IsRegressed = s.Status == StackStatus.Regressed to GetStackTemplateData().

Proof it works (visible in daily summary email — see screenshot): the [REGRESSED] prefix appears on ArgumentNullException in the Most Frequent list.

Coverage Gap Fixed

RunMailJobAsync() in MailerTests.cs only logged the rendered body — zero assertions. All 25 tests would pass even if templates rendered empty HTML or left {{token}} placeholders unsubstituted.

Fix:

RunMailJobAsync() now returns string body
Each of the 26 tests (25 existing + 1 new) asserts template-specific content
New SendProjectDailySummaryWithRegressedStackAsync verifies [REGRESSED] badge

dotnet test -- --filter-class Exceptionless.Tests.Mail.MailerTests
# total: 26 | failed: 0 | succeeded: 26

Email Renders (new Svelte 5 + Tailwind templates)

Verified via Mailpit at http://localhost:8025 after npm run build in src/Exceptionless.EmailTemplates:

Template	Result
Event Notice	✅ Error details table, View Event Details CTA, User Info, structured data
Daily Summary	✅ Stats grid (Count/Unique/New), View Timeline, Most Frequent with [REGRESSED] badge
Organization Invite	✅ Join Organization CTA, Connect/Contact footer
Organization Added	✅ View Organization CTA
Organization Notice (monthly)	✅ Monthly plan limit message
Payment Failed	✅ Update Billing Information CTA
Account Confirmation	✅ Verify Address CTA, personalized greeting
Password Reset	✅ Reset Password CTA

📸 Visual Comparison: All 8 Templates (Before → After)

All templates rendered in Mailpit with identical sample data. Left = main branch (Foundation/Inky), Right = PR (Svelte 5 + Tailwind).

Email Verify

Password Reset

Event Notice

Daily Summary

Note: Both templates show the [REGRESSED] badge because the bug fix in this PR now passes IsRegressed correctly from Mailer.cs. Before this PR, the badge was silently suppressed on main branch despite the template supporting it.

Organization Added

Organization Invited

Organization Notice (Throttled)

Payment Failed

Verification: All 16 emails (8 OLD + 8 NEW) successfully delivered to Mailpit SMTP. All 26 mailer tests pass. 🟢

Follow-up reviewer audit complete at 270cbfa974777fb3b6a80c23732bb5ca050d4419.

I re-read all live review threads, inline comments, submitted reviews, and issue comments against the current branch-vs-main diff. The 18 review threads classify as 14 outdated/already-fixed or superseded-by-the-current implementation and 4 current/already-addressed. One previously resolved human finding had regressed: .gstack/ was removed in response to review, then reintroduced later by 07dbfb878. I removed that unrelated ignore entry again and replied on the original thread with the commit-level RCA and proof.

The thermo-nuclear pass found one additional real boundary gap: parity validation compared visible text and links but did not inspect Gmail application/ld+json actions, so structured-data actions could drift without failing the gate. The validator now parses and exact-compares every JSON-LD document between legacy and modern output. I also removed a redundant CI build step because validate:parity already performs the build.

Verification:

npm run lint — passed
npm run check — 0 errors, 0 warnings
npm run validate:parity -- --semantic-only — 13/13 templates; text, links, and JSON-LD exact
npm run validate:parity — 13/13 semantic checks plus all 26 desktop/mobile pixel comparisons exact
npm run build-storybook — passed
npm audit --omit=dev and npm audit — 0 vulnerabilities
dotnet test tests/Exceptionless.Tests/Exceptionless.Tests.csproj --no-restore -- --filter-class Exceptionless.Tests.Mail.MailerTests — 27/27 passed
git diff --check — passed
replacement CI run — email templates, client, E2E/Aspire, container build, version, and CLA passed; full API test/coverage result recorded by the run

No remaining actionable review concern or external blocker was found. The complete structural pass found no >1,000-line source file, unsafe boundary/type leak, duplicated canonical helper, non-atomic update, or clear behavior-preserving broad refactor beyond the focused CI simplification above.

Addressed the invitation feedback and audited every internal email URL against the Svelte UI.

The organization invitation does not provision an account or password-reset token, so a setup-password page would be the wrong contract. A genuinely new address now follows the invitation email directly to /signup?token=...; if that address has acquired an account before the invitation is accepted, /login?token=... now preserves the token through password and OAuth login and sends it to the API so organization membership is completed. Direct organization links also retain the organization from the URL.

I migrated the remaining legacy email routes to their Svelte equivalents and extended parity validation to discover SvelteKit routes and verify both clean URLs and the current /next deployment prefix.

Verification at 73b07ce9b:

focused invitation E2E: 2/2 passed (new signup and existing-account login)
ClientApp build, full npm run validate, and focused auth unit tests passed
email lint/check passed
all 13 semantic parity scenarios passed
all 26 desktop/mobile comparisons are exact pixel matches
every internal email link maps to a real Svelte route under /next
email package audit: 0 vulnerabilities

Dependencies were updated to the latest compatible releases; remaining outdated entries are major-version upgrades and were intentionally left for separate compatibility work.

Replacement CI is fully green at 73b07ce9b: API/coverage, client, email templates, full E2E, container build, version, and CLA all passed. Run: https://github.com/exceptionless/Exceptionless/actions/runs/30580372048

Replace the legacy Foundation for Emails (Gulp/Inky/Panini/SCSS) toolchain with Svelte 5 + @better-svelte-email + Tailwind CSS. - Migrate all 8 email templates to Svelte components - Add shared EmailLayout, ActionsFooter, SocialFooter components - New build system: Vite SSR + @better-svelte-email/server renderer - Output maintains identical visual appearance and Handlebars tokens - All 25 mailer tests pass with new template output - Remove old build tooling (Gulp, Babel, SCSS, Panini, Inky) The compiled HTML templates preserve Handlebars syntax for runtime rendering by HandlebarsDotNet in the .NET backend (unchanged).

@html

- Migrate 8 email templates from Foundation for Emails / Gulp / Inky / Panini / SCSS to @better-svelte-email/server 2.1.1 + Tailwind CSS - Security audit: Svelte upgraded 5.34.7 → 5.55.9 (patched 6 XSS SSR CVEs) - Pixel-perfect visual parity: all 8 templates verified with before/after screenshots - Centralized design tokens in src/theme.ts (named Tailwind colors: text-primary, bg-dark, text-alert, etc.) — no more hardcoded hex in .svelte sources - Fixed XSS: preheader was {@html preheader}, now plain {preheader} text binding - Add Storybook 10 with stories for all 8 templates + sample data with fillTokens() - Add ESLint (flat config), Prettier, svelte-check — 0 errors, 25/25 tests pass - Add @types/node, vite/client types, skipLibCheck for clean type checking - Fix build script: typed Component, parseInt radix, HTML comment stripping - Fix JSON-LD '}\n}' → '}}' Handlebars parse collision in cleanHtml - Remove compilerOptions.generate from vite.config.ts (Svelte 5 no longer supports it) - Remove old Gulp/Babel/SCSS/Panini/Inky/Foundation toolchain entirely Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

- Rewrite fillTokens in sample-data.ts as a proper Handlebars evaluator supporting if/else/each blocks, nested depth tracking, @index and {{../parent}} scope resolution — fixes token concatenation bug where all {{#if}} branches were showing simultaneously - Fix cleanHtml() to replace newlines in text nodes with a space instead of removing them (was causing 'fromwhich', 'yourapplication', etc.) - Fix text typos in organization-notice.svelte: 'to to continue' → 'to continue', 'to to see' → 'to see', 'being counting' → 'counting' - Add Storybook (port 6006) and EmailStorybook (port 6008) as AddJavaScriptApp resources in Aspire AppHost for integrated development dashboard - Change email Storybook port to 6008 to avoid conflict with Svelte app (6006) - Rebuild all 8 generated HTML templates with whitespace fixes applied - 25/25 mailer tests pass Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

- vite.config.ts: add closeBundle plugin so 'dev' (--watch) regenerates HTML templates on every source change; simplify 'build' script to 'vite build' (plugin handles node dist/build.js). Remove try/catch so renderer failures propagate and fail the build. - sample-data.ts: fix isTruthy to match Handlebars semantics exactly — store @index as a real number so {{#if @index}} is falsy at index 0 (matches HandlebarsDotNet integer semantics); strings 'false'/'null'/ 'undefined'/'' are falsy, all other strings truthy (matching Handlebars.js, not JS). Change BASE_URL to http://localhost:7110. - dependabot.yml: add npm entry for /src/Exceptionless.EmailTemplates - build.yaml: add test-email-templates CI job that runs lint, check, build, and verifies generated HTML is committed and up-to-date Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

@html

- Add IsRegressed to GetStackTemplateData in Mailer.cs - Fix project-daily-summary: wrap all MostFrequent/Newest items in single <ul> - Refactor SocialFooter to use Row+Column components (remove {#@html} hack) - Use Preview component in EmailLayout; remove unconditional spacer div - Replace 200-line custom Handlebars evaluator with handlebars npm package - Move JSON-LD to wrapJsonLd() helper in src/lib/json-ld.ts (avoids Svelte parser treating <script> in template literals as real script elements) - Include src/templates/** in ESLint with no-at-html-tags rule disabled - Remove .gstack/ from repo-root .gitignore - Remove obvious code comments from build-emails.ts - Fix no-unused-vars: remove Link import from user-email-verify.svelte - Regenerate all 8 HTML templates Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

@key

Fields is iterated with {{#each Fields}} where @key = property name and this = value. Using a plain object (not array of objects) matches HandlebarsDotNet's Dictionary<string,string> iteration semantics and produces correct key/value pairs in the Storybook preview.

…lpit Side-by-side comparisons of all 8 email templates rendered in Mailpit. BEFORE = main branch Foundation/Inky HTML, AFTER = PR Svelte 5 + Tailwind. Both rendered with identical sample data to verify pixel-accurate parity. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

@html

…daily summary Use @better-svelte-email/components Row and Column instead of raw HTML strings for the 3-column and 4-column stats tables in project-daily-summary.svelte. Also refactor the throttling text to use a single @html block instead of mixing @html with Svelte Link components. All 26 mailer tests pass.
