🛠️ Extension Guide

Clone this repository.
Copy src/storage/redis.ts to a new file and modify it according to your needs (the learning curve of unjs/unstorage is very friendly).
Test and verify the effects.
(Optional) Submit a merge request.

If you are not a TypeScript developer, please submit an issue to request support for other drivers.

Tips for Cursor/Cline Assisted Programming

@/src/storage/mongodb.ts, please implement this file:
1. You need to use the corresponding documentation URL of the storage type (https://unstorage.unjs.io/drivers/<storage type>) to obtain information.
2. You can refer to the examples in @/src/adapter/redis.ts and @/src/storage/http.ts.
3. You only need to generate the code without performing tests.

🐞 Debugging Methods

Using mcp - inspector

mcp-inspector -e HTTP_BASE=http://localhost:3001 -e HTTP_MOUNT_POINT=http_storage -e FS_BASE=D:/temp -e FS_MOUNT_POINT=fs_storage -e HTTP_HEADERS="Authorization=Bear 123;" tsx ./src/index.ts
