feat(frontend): invoice document upload and verification workflow#242fadesany wants to merge 2 commits into
Conversation
Originators can now attach PDF/image proof documents to an invoice and lenders can verify them before offering financing. - Upload accepts PDF, JPG and PNG up to 10 MB (validated client-side, on the upload route, and in the database) - Files are pinned to IPFS via Pinata (@pinata/sdk) in a server-side route; SHA-256 hashes are stored with the row and re-checked on every read so tampered IPFS objects are never served silently - New invoice_documents table (migration 002) with RLS: only invoice parties (originator or a lender with an offer) can read, only the originator can attach, and only lenders can verify; a trigger limits updates to verification fields and stamps verifier/timestamp - Invoice detail page gains a Documents section with drag-and-drop upload, inline previews (image / PDF iframe), status badges (pending/verified/rejected), and lender verification comments - Adds the stack's first server-only secrets (PINATA_API_KEY / PINATA_SECRET_API_KEY) plus a configurable IPFS gateway, all documented in docs/08-environment-variables.md - 13 new unit tests (hash, validation, status); e2e fixtures stub invoice_documents reads Closes Stellar-VaultLink#222

In `@docs/06-supabase.md`:
- Around line 133-135: Update the runnable SQL block in the Supabase
documentation to define the enforce_document_verification_update trigger
function and create the corresponding BEFORE UPDATE trigger on documents. Ensure
documents_verify restricts authorized lender updates to verification fields
while stamping verified_by and verified_at from the caller session, preventing
changes to ipfs_cid and document_hash.
In `@invofi/apps/frontend/e2e/fixtures.ts`:
- Line 232: Add documents to the options type used by authenticate, matching the
documents fixture accepted by mockSupabaseMirror. Replace the generic object[]
type with the existing document fixture type so invoice-detail tests can provide

- Around line 26-27: Expand the invoice-detail end-to-end coverage beyond the
Documents heading by exercising originator proof-document upload and lender
verification actions, including their expected UI outcomes. Add route-level
coverage for document content hash mismatch and assert that the endpoint returns
HTTP 409, using the existing invoice-detail test helpers and route symbols where
available.
In `@invofi/apps/frontend/src/app/api/documents/upload/route.ts`:
- Around line 41-45: In the upload route, inspect the file bytes after the
existing fileCheck and before uploadBufferToPinata to detect PDF, JPEG, and PNG
signatures independently of file.type. Reject unsupported or mismatched detected
formats, requiring the detected format to match the declared MIME type before
hashing and pinning.
- Around line 30-32: Update the document upload size limit used by the upload
route to remain below Vercel’s 4.5 MB Function request limit, including the
DOCUMENT_MAX_SIZE_BYTES configuration and its validation around formData/file
handling. Preserve the existing 413 response behavior for files exceeding the
revised limit.
In `@invofi/apps/frontend/src/components/invoices/documents/DocumentUploader.tsx`:
- Around line 39-60: The DocumentUploader flow currently pins via
uploadInvoiceDocument before persisting invoice_documents, allowing orphaned
pins and client-side authorization gaps. Move pinning and metadata insertion
into one authenticated server workflow that authorizes the invoice party,
compensates by unpinning the CID when insertion fails, and returns the persisted
document record only after both operations succeed; update DocumentUploader to
use that workflow and its returned record.
In `@invofi/apps/frontend/src/hooks/useInvoiceDocuments.ts`:
- Around line 15-29: The refresh callback in useInvoiceDocuments must ignore
stale query results when invoiceId changes or a newer request starts. Track
request identity with a sequence ID or abort signal, and gate setDocuments,
setError, and setLoading so only the latest request updates state.
In `@invofi/apps/frontend/src/lib/documents/server.ts`:
- Around line 49-57: Update fetchDocumentFromIpfs to enforce
DOCUMENT_MAX_SIZE_BYTES before buffering: reject responses whose Content-Length
exceeds the limit, then stream the response body while counting bytes and
aborting or rejecting once the limit is exceeded, including when Content-Length
is missing or inaccurate. Only construct the buffer after the streamed size has
been validated, preserving the existing contentType and successful
IpfsFetchResult behavior.
- Around line 49-51: Update fetchDocumentFromIpfs to use a bounded
AbortController timeout for the IPFS gateway fetch, pass its signal to fetch,
and clean up the timeout afterward. Detect timeout-induced aborts and map them
to the existing gateway error response while preserving current handling for
other failures.
- Around line 15-17: Update getIpfsGatewayUrl to treat an empty IPFS_GATEWAY_URL
value as unset, returning DEFAULT_IPFS_GATEWAY_URL instead; preserve configured
non-empty gateway values.
In `@invofi/apps/frontend/src/lib/migrations/002_invoice_documents.sql`:
- Around line 50-57: Update the documents_insert policy on invoice_documents to
require uploader_id = auth.uid() and enforce new documents start with status
pending and all verification fields unset, including verified_by and
verified_at, while preserving the existing invoice ownership check.
Apply the same fix in `@docs/06-supabase.md` around lines 125 - 128: The
documentation contains the same insert-policy omission and must apply the same
identity restriction.

Include the verification trigger in the runnable SQL.
This document instructs users to run the SQL block, but the block does not define enforce_document_verification_update. Without that trigger, documents_verify permits an authorized lender to update all document columns, including ipfs_cid and document_hash, not only verification fields.
Add the trigger function and CREATE TRIGGER statement to this block. Alternatively, replace this executable block with a migration-only instruction.

Expose document fixtures through authenticate.
mockSupabaseMirror accepts documents, but authenticate does not declare documents in its options type. Invoice-detail tests that use authenticate cannot provide a non-empty document fixture without a TypeScript error.
Add documents to the authenticate options type. Use a document fixture type instead of object[] so tests must provide the fields used by the document UI.

Next.js App Router route handlers request.formData request body size limit Node runtime official documentation
💡 Result:
In Next.js App Router, Route Handlers (which use the standard Web Request API) do not have a dedicated, per-route configuration object to limit or increase the request body size in the same way the Pages Router's API routes do [1][2][3]. For Route Handlers, the request body is handled by the underlying runtime environment. If you are encountering issues with request body sizes, it is important to distinguish between the two primary scenarios where limitations may occur: 1. Server Actions: If you are using Server Actions instead of Route Handlers, you can configure the body size limit globally in your next.config.js file using the serverActions.bodySizeLimit option [4]. This allows you to increase the default 1MB limit [4]. 2. Middleware/Proxy Buffering: If you are using Middleware or a proxy feature that clones and buffers the request body, Next.js imposes a default limit (typically 10MB) to prevent excessive memory usage [5][6]. This can be adjusted via the middlewareClientMaxBodySize or proxyClientMaxBodySize configuration options in your next.config.js [5][6]. Note that Route Handlers themselves are designed to be isomorphic and use the Web Request API. Unlike the Pages Router's API routes, which use an internal body-parser that can be configured via a route-level export const config = { api: { bodyParser:... } } object [2][7], this mechanism is not supported in the App Router [1]. If your application requires handling very large request bodies, you may need to bypass standard parsing by streaming the request body directly or using alternative architectures (such as dedicated file upload services) to avoid memory or execution limits [2][8].

Vercel Functions request body size limit official documentation 2025
💡 Result:
According to official Vercel documentation, the maximum payload size for the request body (and response body) of a Vercel Function is 4.5 MB [1][2]. If a request exceeds this limit, the function will return a 413: FUNCTION_PAYLOAD_TOO_LARGE error [1][3]. This is an infrastructure-level limit that cannot be increased via configuration files like vercel.json [4]. To handle data larger than 4.5 MB, Vercel recommends alternative architectural patterns, such as: - Uploading files directly to a storage service (e.g., using Vercel Blob or an S3 presigned URL) so that the file data does not pass through the function [5][4]. - Using streaming functions for responses, which are not subject to the same payload size limitations [5].

Align the upload limit with Vercel's request limit. Vercel rejects Function request payloads above 4.5 MB before this route runs. DOCUMENT_MAX_SIZE_BYTES allows 10 MB, so valid files between 4.5 MB and 10 MB fail before the route can return its 413 response. Set the application limit below 4.5 MB, or upload files directly to Pinata/storage and send only metadata through this route.

Validate the file bytes, not only File.type.
file.type is caller-controlled metadata. A client can label arbitrary bytes as application/pdf, image/jpeg, or image/png, and this route will hash and pin them. The content route later serves the stored MIME type as authoritative.
After line 70, validate PDF, JPEG, and PNG signatures from the bytes before calling uploadBufferToPinata. Reject files whose detected format does not match the declared MIME type.

Prevent stale document queries from replacing the current invoice documents.
If invoiceId changes while a prior query is pending, the prior query can complete last and replace the new invoice document list. The user can then view or verify a document from the previous invoice on the current invoice page.

Line 56 buffers the complete gateway response. The database file_size check does not limit these bytes, because the content route does not pass an expected size and an originator can store an arbitrary CID. A large IPFS object can exhaust route memory before the hash mismatch response.
Stream the response and abort after DOCUMENT_MAX_SIZE_BYTES. Reject an oversized Content-Length as an early optimization, but retain the streamed byte limit when that header is absent or false.

Update fetchDocumentFromIpfs to enforce DOCUMENT_MAX_SIZE_BYTES before
buffering: reject responses whose Content-Length exceeds the limit, then stream
the response body while counting bytes and aborting or rejecting once the limit
is exceeded, including when Content-Length is missing or inaccurate. Only
construct the buffer after the streamed size has been validated, preserving the
existing contentType and successful IpfsFetchResult behavior.

Bind uploader identity and initial verification state in every executable RLS definition. The insert policy checks invoice ownership but does not require uploader_id = auth.uid(), so an originator can assign access to another user. It also allows forged initial verification status and metadata because the update trigger does not protect inserts. Require the authenticated uploader, status = 'pending', and null verification fields in both this migration and the runnable SQL block in docs/06-supabase.md.

Thanks @fadesany — the invoice document upload and verification workflow fills a real gap.
CodeRabbit flagged 11 items. Key items:
docs/06-supabase.md: The SQL block needs theenforce_document_verification_updatetrigger function and BEFORE UPDATE trigger. Ensuredocuments_verifyrestricts authorized lender updates to verification fields only.e2e/fixtures.ts: Theauthenticateoptions type needs adocumentsfield matching themockSupabaseMirrordocument fixture type.- Security: Document upload endpoints must validate file type and size server-side. Don't trust client-side validation alone.
Address items 1–3 and push. The rest are minor.

Summary
Closes #222 — implements the invoice document upload and verification workflow. Originators attach PDF/image proof files for an invoice; lenders preview and verify (or reject) them before offering financing.
What changed
Upload & storage (IPFS via Pinata)
POST /api/documents/upload— a server-side route pins the file to IPFS using @pinata/sdk and returns the CID + SHA-256 hash of the bytes. Only the invoice originator may upload (checked server-side and by RLS on the mirror insert).Data model (
src/lib/migrations/002_invoice_documents.sql)invoice_documentstable:ipfs_cid,document_hash(SHA-256),status(pending/verified/rejected),verification_comment,verified_by,verified_at.verified_by/verified_atfrom the sessionReading & tamper detection
GET /api/documents/[id]/content— streams the file from IPFS to an invoice party (non-parties get 404), re-computes the SHA-256 of the fetched bytes, and returns 409 on any mismatch so a tampered/corrupted IPFS object is never served silently.UI (invoice detail page)
Config & docs
PINATA_API_KEY/PINATA_SECRET_API_KEY(read only by route handlers), plus configurableIPFS_GATEWAY_URL— documented indocs/08-environment-variables.md,.env.local.example, and the Supabase schema indocs/06-supabase.md. No CSP changes needed (upload/download are same-origin routes).Acceptance criteria
