 *A heavy-duty web file browser for CRAZY files.*

 ## Features

- Automated cache management
-    - Optionally fill the cache on server start, or as requests come in.
-    - Watch for changes or scan interval.
+- Automated cache management. Fill the cache when the starts, or as requests come in.
 - File browsing API.
 - Download API.
 - Restrict certain files and directories from the download API to prevent users from downloading your entire 100GB+
  dataset.
- Frontend-agnostic design. You can have it serve a simple web interface or just act as a JSON API and serve files.
- Simple resources. The resources for the frontend aren't compiled into the binary which allows you to modify or even
-  replace it.
- Basic searching.
- Elasticsearch integration (to do).

 By default, it looks for your config in the same directory as the executable: `./config.yml` or `./config.yaml`.

-so minutes for it to traverse the directory structure. CrazyFS is heavily threaded so you'll want at least an 8-core

+- Track active crawls and list them on the admin page
+- Limit to one on-demand crawl per path. Don't start another if one is already running. See HandleFileNotFound()
+- Add config value to limit the number of on-demand crawls
+- Add config value to limit the number of concurrent crawls, other crawls get queued.
+- add an admin endpoint to fetch the last n modified files.
+- fix /api/file/download when an item is in the cache but does not exist on the disk
+- Is using scroll for the Elastic query really the best way to do a real-time query?
+
+
+Later:
 - Add a wildcard option to restricted_download_paths to block all sub-directories
 - Add a dict to each restricted_download_paths item to specify how many levels recursive the block should be applied
- Add an endpoint to return restricted_download_paths so the frontend can block downloads for those folders
- Load the config into a global variable and stop passing it as function args
- Remove the file change watcher mode
+- add a "last modified" to "sort" https://chub-archive.evulid.cc/api/file/list?path=/chub.ai/characters&page=1&limit=50&sort=folders
