依賴檢查器

Dependency Inspector

筆者幫它取名為： 依賴檢查器。

我們可以使用它來查看開發者的程式碼使用了多少本地、遠端上合法的 ES 模組：

deno info [URL]

以官網提供的依賴模組 File Server 為例：

deno info https://deno.land/std@0.67.0/http/file_server.ts

Output:

deno info https://deno.land/std@0.67.0/http/file_server.ts

利用依賴檢查器查看快取資訊

此外，我們可以利用 deno info 查看本地快取的位置：

deno info

Output:
