Add Tracwell traffic to the stats page by radiumcoders · Pull Request #56 · radiumcoders/23rd.dev

radiumcoders · 2026-10-29T06:51:09Z

Adds a "Last 30 days" section to /stats from Tracwell's read-only MCP endpoint: visitors and page views with change against the previous 30 days, visitors per day, top pages, sources, countries, and devices.

One stateless analytics_overview call per hourly regeneration, server side only. The key is TRACWELL_MCP_KEY (already set on Vercel, documented in .env.example).
Today is left out so the chart doesn't end on a half day.
Without the key, or if Tracwell fails, the traffic section is hidden and the rest of the page renders.
On phones, bar list rows stack the bar under the label so long paths aren't cut off.

Summary by CodeRabbit

New Features
- The stats page now includes traffic analytics for the last 30 days, including visitor and page-view totals with percentage changes, daily visitor trends, and ranked pages, traffic sources, countries, and devices.
- Traffic analytics appear when data is available; existing project statistics remain.

… daily visitors, top pages, sources, countries, and devices.

Walkthrough

The stats page now fetches Tracwell traffic alongside site statistics. When traffic data is available, it displays 30-day metrics and breakdowns. Shared chart and list components also render weekly commits and project categories.

Changes: Stats Traffic

Layer / File(s)	Summary
Traffic data retrieval `.env.example`, `lib/tracwell.ts`	The environment example adds a `TRACWELL_MCP_KEY` placeholder. `getTraffic` requests the previous 30 full UTC days and maps metrics, trends, and ranked breakdowns.
Reusable stats visualizations `app/(marketing)/stats/page.tsx`	`StatTile` supports optional percentage changes. `BarChart` renders numeric bars, and `BarList` renders ranked rows with links for page paths.
Stats page integration `app/(marketing)/stats/page.tsx`	The page fetches site statistics and traffic concurrently. When traffic is available, it renders traffic tiles, daily visitor bars, and ranked breakdowns. Project metrics use the shared chart and list components.

Merge Risk: Moderate · up to 801a6

An empty traffic trend could prevent the entire stats page from rendering, rather than hiding only traffic. Guard that case before merging; confirm the top-page metric against Tracwell’s response contract.

Full details: Title check

Explanation

The title "Add Tracwell traffic to the stats page" matches the main change. The changeset adds a traffic section to /stats that uses the Tracwell analytics MCP endpoint through a new getTraffic function in lib/tracwell.ts. The title is specific and concise, and it names the feature and the page it affects. It does not cover details such as the hidden-when-unavailable behavior or the shared chart components, which is acceptable for a title.

Full details: Docstring Coverage

Explanation

Docstring coverage is 20.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 5 functions across 2 files. (1 skipped: 1 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Guard the endpoint labels when the traffic trend is empty.

If the Tracwell trend array is empty, /stats can fail to render. getTraffic() passes the empty array through as days, and BarChart then reads bars[0].label without a length check. The error happens during page render, outside the try block in getTraffic(), so the fallback that hides the traffic section does not catch it. The Project section does not render either.

Use optional access for the endpoint labels. An empty chart then renders with blank endpoint labels:

Minor · Functional Correctness · Quick win

Use page views for top pages.

top() uses row.count for every breakdown, including breakdowns.pages. Tracwell presents top pages by views, and the response has a separate row.views field. When those fields differ, /stats shows the wrong page totals. Select views for pages and rank those rows by the same field. (tracwell.app)
