📦 NuGet Download Stats 动态下载图表

memoryfraction · GitHub · data: nuget.org live totals + daily snapshots (stats/history.jsonl)

Period downloads + cumulative trend

Bars = downloads in the selected period (day / ISO-week / calendar-month / calendar-year); in Year view each bar is stacked by version share; line = cumulative lifetime total at period end. 柱 = 当期下载量（年份视图柱内按版本分段叠加）；线 = 期末累计总量。

Estimated organic vs. automated downloads 自然下载估计

Each day's delta is split by version against its nuget.org publish date: release burst = downloads to a version within days of publishing (mirrors / scanners / cache warmers fetch every new version); old-version sweep = downloads to superseded versions, plus the same floor subtracted from the latest when a sweep hits every old version at once; organic = what remains on the current latest version. A heuristic estimate, not ground truth — it cannot tell a human from a CI restore. Dashed lines = releases. HealthData.Interop.* components are pulled in by the Fhir meta-package, so don't add them to Fhir.
按版本拆分每日增量：发版脉冲 = 版本发布后天内的下载（镜像 / 扫描器会抓取每个新版本）；旧版本扫描 = 对已被取代版本的下载（所有旧版本同时 +1 时，最新版本也扣除同样的底数）；自然 = 最新版本上剩余的下载。启发式估计，无法区分真人与 CI 还原。虚线 = 发版。

Per-version breakdown（按版本，最新快照）

Latest snapshot · NuGet only publishes lifetime-cumulative per-version totals.

📊 Data source & granularity 数据源与粒度

NuGet public APIs expose lifetime cumulative downloads (per package / per version, CORS-open) plus a rolling “last 6 weeks” window at www.nuget.org/stats/reports/packages/{id} — the data behind nuget.org’s “Package Downloads” page, pivotable by version / client name. It has no CORS header (server-side only), a fixed 6-week window, and is not a time series. The v3 stats time-series API is gone (all endpoints 404 — re-verified 2026-08-25; no Stats resource in the v3 service index).
NuGet also publishes each version’s release timestamp (second precision, registration API) — but that is release dates, not downloads-over-time.
Finest granularity = DAY, and it is derived: a GitHub Actions workflow snapshots the cumulative counters once per day (11:30 UTC); a day’s downloads = difference between consecutive snapshots.
Week / Month / Year views = calendar aggregations (ISO week / month / year) of those daily deltas. In Year view each bar is stacked by version share.
Sub-day (hourly) precision: not possible — no public NuGet source provides it.
NuGet’s counters update with a lag (hours), so the latest day may be under-counted until the next snapshot.

NuGet 公开 API 提供：累计总下载量（按包 / 按版本，支持浏览器跨域）＋ www.nuget.org/stats/reports/packages/{id} 的滚动“近 6 周”窗口（可按版本 / 客户端拆分，即 nuget.org “Package Downloads” 页面的数据源；无 CORS、固定 6 周窗口、仅服务端可调用，且不是时间序列）。v3 统计时间序列接口已下线（2026-08-25 实测全部 404，v3 service index 无 Stats 资源）。
注册 API 还提供每个版本的发布时间戳（精确到秒）——但那是发布时间，不是下载量时间序列。
最细粒度 = 天，且属于推导值：GitHub Actions 每天 11:30 UTC 快照一次累计计数，某天的下载量 = 相邻两次快照的差值。
周 / 月 / 年视图 = 对这些日增量按日历周（ISO）/ 月 / 年的聚合。年份视图柱内按版本分段叠加。
小时级更细：任何公开 NuGet 数据源都不支持。
NuGet 计数器本身有数小时延迟，最近一天可能要等下一次快照才完整。
