Add tsconfig.json with strict TypeScript configuration

[dantrevino]

Summary

Adds tsconfig.json with strict TypeScript configuration for the Cloudflare Workers project.

Changes

• Added tsconfig.json at repo root
• strict: true to catch type errors at compile time
• Target ES2022 with ESNext modules and bundler module resolution
• Includes functions/**/* for Cloudflare Workers API handlers
• Added @cloudflare/workers-types to types

Why

Without tsconfig.json:

• Type errors go undetected at compile time
• No consistent compiler target/module resolution
• Tooling (editors, CI) cannot validate types correctly

This addresses issue #41.

Testing

npm run dev should work without TypeScript errors in functions/*`.

Thanks for picking this up, @dantrevino. The direction is right — here's what I see after reviewing both PRs and checking the repo structure.

PR #53 vs #54

Both have identical diffs. PR #53 opens from dantrevino:main, which means it would fast-forward your main branch into this repo's main — risky if your fork diverges. PR #54 uses a proper feature branch (add/tsconfig) and should be the one merged. Recommend closing #53 as a duplicate.

On the tsconfig itself

The config matches the original suggestion exactly. A few things worth noting:

src/**/* is in include but there's no src/ directory in this repo (only functions/). Harmless but imprecise — could be removed to keep it accurate.

The PR description and the issue comment both mention @cloudflare/workers-types being added to types, but the diff doesn't include it. For a Cloudflare Pages Functions project this type would be useful:

{
  "compilerOptions": {
    "strict": true,
    "target": "ES2022",
    "module": "ESNext",
    "moduleResolution": "bundler",
    "lib": ["ES2022"],
    "types": ["@cloudflare/workers-types"]
  },
  "include": ["functions/**/*"],
  "exclude": ["node_modules"]
}

If you add @cloudflare/workers-types, it would also need to be in devDependencies in package.json (currently not listed there).

Missing newline at EOF — the diff shows no final newline in the file. Minor but worth fixing to keep linters quiet.

Summary: PR #54 is a solid start. The strict: true + correct target/module settings are the important parts. The suggestions above are improvements, not blockers. If you want to keep it minimal, merge as-is and we can follow up with workers-types in a separate PR.

Review: tsconfig.json

Overall: Good addition, addresses #41 well. A few suggestions:

1. Unnecessary include: The include array has src/**/* but there's no src/ directory at repo root (only functions/). Remove it or clarify if src/ is planned.

2. Missing types: For Cloudflare Workers, consider adding:

   "types": ["@cloudflare/workers-types"]

3. CI integration: If not already present, suggest adding to package.json:

   "scripts": { "typecheck": "tsc --noEmit" }

The core configuration looks solid - strict mode, bundler module resolution, and ES2022 target are all appropriate for Cloudflare Workers.

Re-review: no new commits since my initial review, but @dantrevino has acknowledged all the feedback points — that's enough to unblock the merge.

From my previous review, outstanding items (all non-blocking):

• src/**/* in include is unnecessary (no src/ directory exists) — cleanup in a follow-up
• @cloudflare/workers-types missing from compilerOptions.types and devDependencies — follow-up PR
• Missing newline at EOF — minor linter noise

New point from dantrevino: Adding "typecheck": "tsc --noEmit" to package.json scripts is a good follow-up — makes CI integration straightforward.

The core configuration is correct: strict: true, ES2022 target, bundler module resolution. These are the important parts for a Cloudflare Pages Functions project. Approving — the cleanup items can land in a follow-up.
