Direzione di ricerca
Start with lib/tools.ts and the Tool interface, then use app/(tools)/base64/ as the route and UI reference; read the README's "Add a tool" section for the checklist. Implement and test pure UUID logic in lib/uuid.ts and lib/__tests__/uuid.test.ts, then build the route /uuid-generator and its client UI. Done means the scoped v4/v7 generation and inspection work, the listed tests pass, and npm run lint && npm run test && npm run build succeeds.

Descrizione
Generate random (v4) and time-ordered (v7, RFC 9562) UUIDs locally, and inspect a pasted UUID to see its version, its variant and, for v7, the timestamp inside it.
Route: /uuid-generator
Suggested registry values: title UUID Generator & Inspector, tagline Identifiers, heroHeading UUID Generator & Inspector with heroDim &, features ["UUID v4", "UUID v7", "Bulk", "Inspect", "No hyphens"].
Core logic in lib/uuid.ts
uuidV4(random: Uint8Array)anduuidV7(nowMs: number, random: Uint8Array). They take randomness and time as arguments so they're easy to test; the UI passes bytes fromcrypto.getRandomValues.- v7 layout: a 48-bit big-endian Unix timestamp in milliseconds, version bits
0111, variant bits10, and the rest random formatUuid(bytes, { uppercase, hyphens })inspectUuid(text)returning{ ok, version, variant, timestampMs? }, recognising the nil and max UUIDs; malformed input returnsok: false
v1 scope
- Generate 1 to 100 UUIDs with a v4 / v7 toggle
- Uppercase and no-hyphens toggles
- Copy all
- An inspector input
Out of scope for v1: v1, v3, v5, v6, ULID and nanoid (good follow-up issues).
Where to look
lib/tools.ts(the registry and theToolinterface)app/(tools)/base64/(a complete tool to copy the structure from)- The "Add a tool" section of the README
Acceptance criteria
- Tests: correct version nibble and variant bits for v4 and v7, the v7 timestamp round-trips through
inspectUuidfor a fixednowMs, two v7 UUIDs with increasing time sort in order, formatting options, malformed input rejected, and the nil UUID detected - UI as scoped above
- The standard new-tool checklist below is complete
Standard new-tool checklist
Everything (home grid, metadata, JSON-LD, OG image, sitemap, manifest, command palette) is driven by the registry in lib/tools.ts, so a new tool is mostly one registry entry plus a route.
- Add an entry to
TOOLSinlib/tools.tsfilling every field of theToolinterface (lib/tools.ts:19-52). UseapplicationCategory: "DeveloperApplication", reuse theCTA_PROJECTS/CTA_CONTACTconstants for the CTA links, and setsitemapPriority: 0.9like the other tools. - Pick
accentVarfrom the accent variables inapp/globals.css(the list is under "Adding a tool" in CONTRIBUTING.md). Take one that no tool uses yet, or the one the fewest tools have if they're all taken. Don't use--rose, it's the color of error messages. SetaccentHexto that variable's dark-theme value.heroDimmust be""or a substring ofheroHeading. - Write 3 or 4 FAQs (3 renders as a 3-column grid, see
components/shared/ToolPageLayout.tsx:25). KeepmetaTitleunder 60 characters andmetaDescriptionaround 150 to 160. - Keep
featuresandogDescriptionto plain Latin text and punctuation. The social card font is a subset with no arrow or symbol glyphs (lib/og.tsx:33-36). - Create
app/(tools)/<slug>/page.tsx,<Name>Client.tsx(with"use client"), andopengraph-image.tsx. Copypage.tsxandopengraph-image.tsxfromapp/(tools)/base64/and change the slug. - Put all pure logic in
lib/<name>.ts(no React, no DOM) with tests inlib/__tests__/<name>.test.ts. Tests can import with@/like the app does (vitest.config.tshas the alias). - Nothing leaves the browser: no network calls with user input, no analytics, no third-party scripts (the CSP in
middleware.tsblocks external scripts anyway). - Reuse shared pieces:
CopyButton,useToast, and optionallyuseRegisterCommandsfor command palette actions (example inapp/(tools)/base64/Base64Client.tsx:43-53). - Every input has a visible label or an
aria-label, the tool works with the keyboard alone, and it looks right in both light and dark themes. - Add the tool to the "Which tool?" dropdown in
.github/ISSUE_TEMPLATE/bug_report.yml. -
npm run lint && npm run test && npm run buildpasses.
One new tool per contributor, so more people get a chance. Add your registry entry at the end of TOOLS and rebase on develop before asking for review, since other new tools will touch the same file.
