f9c4061: fix(blob): Enforce content-type on fetch requests during token generation
f9c4061: fix(blob): Enforce content-type on fetch requests during token generation
Before this change, we would not send the content-type header on fetch requests sent to your server during client uploads. We consider this a bugfix as it should have been sent before.
⚠️ If you upgrade to this version, and you're using any smart request body parser (like Next.js Pages API routes) then: You need to remove any JSON.parse(request.body) at the handleUpload step, as the body will be JSON by default now. This is valid for the onBeforeGenerateToken and onUploadCompleted steps.

mode: folded | expanded (default) parameter to the list command options. When you pass folded to mode, then we automatically fold all files belonging to the same folder into a single folder entry. This allows you to build file browsers using the Vercel Blob API.Nothing published for this version

8251462: This release introduces BREAKING CHANGES. Mostly, we've separated client and server needs better. While ensuring we only export what we currently think is useful to you.
We have a completely new documentation about client (browser) uploads: https://vercel.com/docs/storage/vercel-blob/quickstart#client-uploads.
We've moved and renamed client-related utilities, including the ones to generate client tokens, to a separate entry file: @vercel/blob/client. Use it this way:
import {
upload,
handleUpload,
generateClientTokenFromReadWriteToken,
} from '@vercel/blob/client';
Here are the new features:
clientPayload?: string option during client uploads via the upload method. This payload can be used to attach metadata to your file, for example when updating a blog post cover image, you may want to pass: clientPayload: JSON.stringify({ postId: 123 }), so you can then use it server side to update the blog post.Here are the BREAKING CHANGES:
handleBlobUpload has moved to client/handleUploadupload instead of put. Also, the handleBlobUploadUrl option has been renamed to handleUploadUrl.verifyCallbackSignature is no more exported if you think you need it, open an issueBlobCommandOptions type is no longer exported. This is an internal utility type. Other internal types were removed also but nobody was using themmetadata in onBeforeGenerateToken and onUploadCompleted has been renamed to tokenPayloadEnjoy!

in seconds. Default to one year (browser) and 5 minutes (edge). The edge cache
is currently always set to a maximum of 5 minutes. But can be lowered to 0a2a4757: Removes utf-8-validate dependency and sets minimum Node.js version to 18.14
e273673: BREAKING CHANGE: Some methods responses and types have been updated following a migration Vercel did to make Vercel Blob more robust and closer to the S3 API.
Namely:
public.blob.vercel-storage.com/zyzoioy8txfs14xe/somefile-NoOVGDVcqSPc7VYCUAGnTzLTG2qEM2.txt
to
zyzoioy8txfs14xe.blob.vercel-storage.com/somefile-NoOVGDVcqSPc7VYCUAGnTzLTG2qEM2.txt
This change has been done transparently: all previous blob urls are
redirected to the new domain..put() no more sends back size and uploadedAt, use .head() to get this
information. Refer to the PutBlobResult type..list() no more sends back contentType and contentDisposition on the
blobs property. Refer to the ListBlobResult type..del() doesn't return any value (void). If the file was here prior to
a del() call, then it's now deleted.BlobResult type has been splitted to PutBlobResult for put() and
HeadBlobResult for head(). Use them accordingly.We've reworked our README to better surface the browser-upload and server-upload methods.
978a817: Added an API version string when activated, related to multi bucket migration, no need to update for now.
ce4b585: Add handleBlobUpload wrapper
08caff4: expose validUntil field
### Patch Changes - Updated dependencies [30fe8d0] - @vercel/postgres@0.9.0
30fe8d0: Upgrade underlying @neondatabase/serverless to 0.9.3. We follow @neondatabase/serverless's versioning scheme, thus the major bump.
The main changes, per https://github.com/neondatabase/serverless/blob/main/CHANGELOG.md, are:
- Use a single (per-region) domain name for all connections to Neon databases. Intended to help with connection caching in V8. Passes the endpoint ID inside connection options for WebSocket connections.
- Deprecate fetchConnectionCache option, which is now always enabled. For neon http fetch queries, enable setting options on individual queries within a batch transaction (but note that the types still do not allow this).
- Pass username (and database name) through URL decoder, so all usernames can successfully authorize.
Upgrading to this version should be safe for all users.
Also fixes #701

52ce540: Before this release, when using our default pooling client (import { sql } from '@vercel/storage'), and deploying on Vercel Edge Functions,
then your Edge Functions would timeout after 11 requests.
Full explanation: we set node-postgres Pool maxUses parameter to 1 in Edge Function, because clients can't be reused between requests in this serverless context.
This combined with how our module is made (a JavaScript proxy) triggered a specific condition where clients would never be released to the Pool.
The exact line that failed under these circumstances was: https://github.com/brianc/node-postgres/blob/735683c5cb41bcbf043c6490be4b7f38cfe3ac48/packages/pg-pool/index.js#L166
This is now fixed, thanks @cramforce.
