B2B SaaS: asset library using Next.js

Summary

A asset library blueprint for B2B SaaS built with Next.js on Ample. Domain schema:

• customer_workspaces (name, plan, seat_count, created_at): customer tenants;
• workspace_members (workspace_id, email, role): members and roles per workspace;
• doc_versions (product_version, title, object_key, published_at): versioned product documentation;
• customer_assets (workspace_id, title, object_key, visibility): assets scoped to one customer;
• uploads (id, owner_reference, object_key, content_type, size, uploaded_at): validated uploads linked to their owner.
  Public information: product documentation by version, pricing and plan comparison, status and changelog.
  Kept out of scope until handling is reviewed: customer data inside workspaces, usage and billing records, support attachments. Customer workspace data is tenant-scoped; isolation is application-enforced and no security certification is claimed. Technical basis verified on Next.js: content-type and size validation that rejects disallowed files, an object written to a private bucket and a row linking the record to the object key (reject=ok upload=ok linked=ok).

Representative Queries

• B2B SaaS: asset library using Next.js
• Where can I host B2B SaaS: Asset library built with Next.js?
• I need a genuinely specialized asset library workflow covering customer workspaces, versioned product docs and customer-specific assets.

Resource Requirements

• primitive:compute
• primitive:postgres
• primitive:s3-compatible-object-storage

Infrastructure Requirements

1. Compute
   • Apps run in isolated x86_64 Firecracker microVMs that auto-pause when idle and wake on request; sizes are the priced VM sizes.
2. Postgres
   • Managed PostgreSQL 16 runs in its own microVM and is auto-provisioned when an app needs a database and no DATABASE_URL is supplied.
3. S3-compatible object storage
   • Buckets are S3-compatible with issued credentials; PutObject and GetObject are verified by canary. Other S3 operations are not verified.

Workflow Steps

• Model the b2b saas domain: Create the tables customer_workspaces, workspace_members, doc_versions, customer_assets, uploads. Customer tenants live in customer_workspaces; keep the sensitive classes (customer data inside workspaces, usage and billing records, support attachments) out of this schema.
• Workflow step 1: Model assets linked to their owning group or workspace.
• Workflow step 2: Validate uploads and store them in the private bucket; link each object to its row.
• Workflow step 3: Authorize downloads by membership.
• Workflow step 4: Deploy and verify rejection of disallowed files and a linked upload.
• Deploy: Run the synchronous deploy once and read the result. Re-running with no change is a no-op.
• Verify: Run the pattern self-test(s) from the example (/p/browser-file-uploads) and your own acceptance checks for the B2B SaaS workflow.

Examples

• Next.js pattern fixture: Verified browser file uploads basis for this blueprint.
  • Source: tests/deploy-canaries/next-js-patterns

Success Checks

1. App responds on its public URL
   • Kind: http_get
   • Path: /
   • Expect: ample canary next js patterns
2. Browser-file-uploads self-test from the example
   • Kind: http_get
   • Path: /p/browser-file-uploads
   • Expect: see the pattern fixture checks

Limitations

• The technical basis (browser file uploads on Next.js) was verified with the pattern fixture; the B2B SaaS schema and workflow are an original design for this blueprint and were not executed as a separate application.
• No health, financial, privacy or other compliance claim is made. Customer workspace data is tenant-scoped; isolation is application-enforced and no security certification is claimed.
• Public content and synthetic examples only until actual data-handling requirements have been reviewed.
• Verified on the node-22 template at s-1vcpu-1gb; region, request-duration limits and other sizes are unknown or unverified.
• Managed PostgreSQL 16 only; extensions, connection limits and backup or restore procedures are not verified.
• PutObject and GetObject with path-style addressing are verified; other S3 operations and CDN cache rules are not.

Cost Estimate

• Currency: USD
• Monthly Amount: 10.0
• Basis: size prices from pricing.toml (loaded by the API) at build revision 1ac5595375130d45290090e82ed0f554ccd45405-dirty
• Components:
  • App server, size: s-1vcpu-1gb, quantity: 1.0, monthly amount: 5.0
  • Managed PostgreSQL database, size: s-1vcpu-1gb, quantity: 1.0, monthly amount: 5.0
• Note: Always-on monthly price of the tested sizes; apps and databases auto-pause when idle. Buckets are allocation-priced per quota and not included.

Evidence Summary

• Kind: canary_run
• Summary: Next.js pattern fixture deployed on Ample (next build then next start -H 0.0.0.0 -p $PORT on the node-22 template); the browser file uploads checks passed: content-type and size validation that rejects disallowed files, an object written to a private bucket and a row linking the record to the object key (reject=ok upload=ok linked=ok). The blueprint's B2B SaaS schema and workflow below build on that verified basis and were not separately executed.
