  1. Setup a storage account and load it up with Shadow.

  2. Use wrangler secret put to setup PRIVATE_KEY https://github.com/openchaindev/cloudflare-shadow-uploader/blob/5bf2559f1491e9986f3643bf9d5187f2c4eb75c6/src/index.ts#L75

  3. Edit Config.SHADOW_ACCOUNT https://github.com/openchaindev/cloudflare-shadow-uploader/blob/5bf2559f1491e9986f3643bf9d5187f2c4eb75c6/src/Config.ts#L3 , can also be setup via wrangler secret if you prefer

  4. Run wrangler publish

Usage

  1. GET / will return the SHADOW_ACCOUNT details, storage-account-info and list-objects https://github.com/openchaindev/cloudflare-shadow-uploader/blob/86b5d4185f242ad398bd207d88f8ce58744cf5bf/src/index.ts#L43-L47

  2. GET/${ARWEAVE_NAME}

2.1. Will first try to fetch it from Shadow Drive https://github.com/openchaindev/cloudflare-shadow-uploader/blob/5bf2559f1491e9986f3643bf9d5187f2c4eb75c6/src/index.ts#L67-L73

2.2. If 2.1 doesn't find the file, get its content from arweave https://github.com/openchaindev/cloudflare-shadow-uploader/blob/5bf2559f1491e9986f3643bf9d5187f2c4eb75c6/src/index.ts#L78

2.3. Upload it to Shadow Drive https://github.com/openchaindev/cloudflare-shadow-uploader/blob/5bf2559f1491e9986f3643bf9d5187f2c4eb75c6/src/index.ts#L84

2.4. Fetch it from Shadow Drive and serve it https://github.com/openchaindev/cloudflare-shadow-uploader/blob/5bf2559f1491e9986f3643bf9d5187f2c4eb75c6/src/index.ts#L91

  • Technically, can skip 2.4 and fetch 2.2 data to improve speed, but it's sort of a sanity check

  • If file is already hosted on Shadow Drive , 2.1 will return its content early
