# Tutoring centers: member portal using Next.js

## Summary

A member portal blueprint for tutoring centers built with Next.js on Ample. Domain schema:

- **course_groups** (subject, level, start_at, end_at, capacity): tutoring groups;
- **memberships** (course_group_id, student_reference, guardian_reference, role): students, guardians and tutors;
- **sessions** (course_group_id, starts_at, tutor, attendance_count): session events;
- **materials** (course_group_id, title, object_key, visibility): worksheets and answer keys;
- **document_access** (document_id, principal_reference, role, granted_at): who may read which document.

Public information: subjects and levels, schedule and locations, tutor qualifications. Kept out of scope until handling is reviewed: minor students and guardian identity, progress reports.

## 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 create` passed as encrypted S3_* environment variables
- A review of which tutoring centers data classes may be handled at all; this blueprint models public information only

## Steps

1. **Model the tutoring centers domain.** Create the tables course_groups, memberships, sessions, materials, document_access. Tutoring groups lives in course_groups; keep the sensitive classes (minor students and guardian identity, progress reports) out of this schema.
2. **Workflow step 1.** Model groups, memberships and roles
3. **Workflow step 2.** Authorize access to materials by membership and role (401, 403 negative tests)
4. **Workflow step 3.** Store materials in the private bucket and stream them through the app
5. **Workflow step 4.** Deploy and verify the negative tests and an authorized download
    
    ```
    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=...
    ```
6. **Verify.** Run the pattern self-test(s) from the example (/p/private-document-library) and your own acceptance checks for the tutoring centers workflow.
    
    ```
    ample logs <deployment_id> --kind build
    ```

## Tested examples

- **Next.js pattern fixture** (tests/deploy-canaries/next-js-patterns): Verified private document library basis for this blueprint.

## Cost estimate

Estimated 10.00 USD per month (size prices from pricing.toml at build revision a1b8c38919e59cd035ebabaced73cf84ece24371).

- 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 (next build then next start -H 0.0.0.0 -p $PORT on the node-22 template); the private document library checks passed: a role-to-document access model with negative tests (401 without identity, 403 for the wrong role) and a private-bucket round-trip for the allowed role (private=ok). The blueprint's Tutoring centers schema and workflow below build on that verified basis and were not separately executed.
