CI / Secret scan (gitleaks) (pull_request) Failing after 12s
refactor: newsletter signup posts no credential (SEC-14-R1 option a)
Rework PR #15 per security review SEC-14-R1: the client no longer carries
an API token. js/newsletter-config.js ships only the non-secret endpoint,
enforced https-only at config load time via validateEndpoint() (mirroring
the protocol allowlist in js/reading-list.js); js/newsletter.js POSTs
email-only with no Authorization header. Failure paths keep the single
user-safe message that never leaks token, endpoint, status, or raw body;
success still shows the confirmation. CI gains a gitleaks step that fails
on any secret hit; README documents the server-side token, the residual
signup-abuse risk, and the authoritative server-side validation follow-up.

# Personal Blog
A small static personal blog. No build step, no backend — plain HTML, CSS, and
vanilla JavaScript.
## Pages
- `index.html` — home page
- `reading.html` — reading list page (curated links grouped by category,
rendered from `data/reading-list.js`)
- `contact.html` — contact page (opens the visitor's mail client with the form
fields pre-filled via a `mailto:` link)
- `newsletter.html` — newsletter signup page (posts the visitor's email to a
configured serverless endpoint; no self-hosted backend or subscriber list
management)
## Newsletter signup
The signup form on `newsletter.html` POSTs the visitor's email to a serverless
endpoint. The client ships only the endpoint URL — no credential is ever sent
in the request:
- `NEWSLETTER_ENDPOINT` — the serverless endpoint the form POSTs to. This is
the **only** thing configured in `js/newsletter-config.js`, and it is
enforced `https://`-only at config load time and by tests (mirroring the
protocol allowlist in `js/reading-list.js`).
**Authentication is server-side only.** The serverless function reads its API
token from platform env/secrets at deploy time — never from this repository and
never from any client-served asset. Do not add a token to `js/newsletter-config.js`
or anywhere else in the tree; anything committed here is public.
When the endpoint is unavailable or rejects the submission, the visitor sees a
fixed, user-safe error message — the server-held token, the endpoint, the status
code, and any raw response body are never surfaced. After a successful signup a
confirmation message is shown.
**Server-side validation (required follow-up on the function, not this diff):**
the serverless function must authoritatively validate submissions before
processing — email syntax, length caps, pinned `Content-Type`, and rejection of
unknown fields. Client-side checks here are UX only and are bypassable by
direct API calls.
**Residual signup-abuse risk (accepted, out of scope):** this pass adds no spam
filtering or captcha. Scripted signups remain possible, so the serverless
function must mitigate abuse server-side with rate limiting and an origin
allowlist.
## Reading list
The reading list is a single data file: `data/reading-list.js`. The page code
renders whatever is in it, so it can grow to hundreds of entries without code
changes.
To add a link, edit `data/reading-list.js` only — add an entry with a `title`,
a `url`, a `category`, and an optional one-line `note`:
```js
{
category: "Engineering",
title: "A new article",
url: "https://example.com/article",
note: "Optional one-liner shown under the title.",
},
```
Categories appear on the page in the order they are first used; entries keep
the order they are listed in.
## Development
Serve the directory with any static file server, e.g.:
```sh
python3 -m http.server 8000
```
Then open <http://localhost:8000>.
## Tests
Tests use Node's built-in test runner (no dependencies to install):
```sh
npm test
```
## Project layout
```text
index.html Home page
reading.html Reading list page
contact.html Contact page
newsletter.html Newsletter signup page
css/style.css Global + responsive styles
data/reading-list.js Curated reading list data (edit to add links)
js/newsletter-config.js Newsletter endpoint (non-secret, https-only) — edit at deploy time
js/newsletter.js Newsletter signup wiring: credential-free POST + user-safe errors (tested)
js/mailto.js Pure mailto: URL builder (unit tested)
js/contact.js Contact form wiring (browser + tests)
js/reading-list.js Reading list renderer: data file -> grouped HTML (tested)
tests/ Node built-in test suite
.gitea/workflows/ ci.yml runs `npm test` plus a gitleaks secret scan (fails on any hit) on PRs and pushes to main
