Architecture practices: form collection using Next.js
Summary
A form collection blueprint for architecture practices built with Next.js on Ample. Domain schema: client_entities (name, entity_type, site_address): clients and project sites; projects (client_entity_id, project_name, stage, period_start, period_end): engagement periods by RIBA/AIA-style stage; drawing_sets (project_id, set_name, revision, object_key, issued_at): versioned drawing issues; approvals (project_id, drawing_set_id, approver_role, decided_at, decision): client sign-offs per issue; uploads (id, owner_reference, object_key, content_type, size, uploaded_at): validated uploads linked to their owner. Public information: portfolio and services, team and accreditations, studio locations. Kept out of scope until handling is reviewed: unreleased drawings and site surveys, planning submissions before filing, client contact details. Drawings and surveys are client-confidential until issued; the portal models per-project authorization only. 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).
Infrastructure requirements
- Compute: verified (Apps run in isolated x86_64 Firecracker microVMs that auto-pause when idle and wake on request; sizes are the priced VM sizes.)
- Postgres: verified (Managed PostgreSQL 16 runs in its own microVM and is auto-provisioned when an app needs a database and no DATABASE_URL is supplied.)
- S3-compatible object storage: verified (Buckets are S3-compatible with issued credentials; PutObject and GetObject are verified by canary. Other S3 operations are not verified.)
Prerequisites
- A Next.js project (next build then next start -H 0.0.0.0 -p $PORT on the node-22 template)
- A PostgreSQL driver reading DATABASE_URL (auto-provisioned when omitted)
- Bucket credentials from
ample bucket createpassed as encrypted S3_* environment variables - A review of which architecture practices data classes may be handled at all; this blueprint models public information only
Exact tested configuration

npm run start
Steps
Model the architecture practices domain. Create the tables client_entities, projects, drawing_sets, approvals, uploads. Clients and project sites lives in client_entities; keep the sensitive classes (unreleased drawings and site surveys, planning submissions before filing, client contact details) out of this schema.
Workflow step 1. Model document requests per engagement with due dates and status
Workflow step 2. Validate uploaded files (type, size) before storing them in the private bucket and linking them to the request
Workflow step 3. Authorize uploads by client entity
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.
ample deploy . --name <app-name> --public --env S3_ENDPOINT=... --env S3_REGION=... --env S3_BUCKET=... --env S3_ACCESS_KEY_ID=... --env S3_SECRET_ACCESS_KEY=...Verify. Run the pattern self-test(s) from the example (/p/browser-file-uploads) and your own acceptance checks for the architecture practices workflow.
ample logs <deployment_id> --kind build
Tested examples
- Next.js pattern fixture (tests/deploy-canaries/next-js-patterns): Verified browser file uploads basis for this blueprint.
Success checks
- app responds on its public URL (
/on the live URL, expect ample canary next js patterns) - browser-file-uploads self-test from the example (
/p/browser-file-uploadson the live URL, expect see the pattern fixture checks)
Limitations
- The technical basis (browser file uploads on Next.js) was verified with the pattern fixture; the architecture practices 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. Drawings and surveys are client-confidential until issued; the portal models per-project authorization only.
- 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
Estimated 10.00 USD per month.
- app server x1
s-1vcpu-1gb: 5.00 USD - managed PostgreSQL database x1
s-1vcpu-1gb: 5.00 USD
Always-on monthly price of the tested sizes; apps and databases auto-pause when idle. Buckets are allocation-priced per quota and not included.
Verification evidence
- canary_run on 2026-09-21T02:34:39Z: Next.js pattern fixture deployed on Ample; 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 Architecture practices schema and workflow below build on that verified basis and were not separately executed. (expires 2027-03-20T02:34:39Z)
