# Course creators: asset library using Laravel

## Summary
A asset library blueprint for course creators built with Laravel on Ample. Domain schema:
- **course_groups** (name, start_at, end_at, capacity): cohorts as course groups;
- **memberships** (course_group_id, member_email, role, joined_at): learner and instructor membership;
- **sessions** (course_group_id, starts_at, title, recording_object_key): session events and recordings;
- **materials** (course_group_id, title, object_key, visibility): teaching materials;
- **uploads** (id, owner_reference, object_key, content_type, size, uploaded_at): validated uploads linked to their owner.

Public information: course catalog and syllabus, instructor profile, schedule. Kept out of scope until handling is reviewed: learner progress and grades, recordings showing learners, payment status. Recordings and progress data are personal data; materials are authorized per course group.

Technical basis verified on Laravel: 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
- Course creators: asset library using Laravel
- Where can I host Course creators: Asset library built with Laravel?
- I need a genuinely specialized asset library workflow covering course structure, member entitlements and downloadable materials.

## Resource Requirements
- **Primitive Compute**
- **Postgres**
- **S3-compatible object storage**

## Infrastructure Requirements
- **Compute:** Apps run in isolated x86_64 Firecracker microVMs that auto-pause when idle and wake on request; sizes are the priced VM sizes.
- **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.
- **S3-compatible object storage:** Buckets are S3-compatible with issued credentials; PutObject and GetObject are verified by canary. Other S3 operations are not verified.

## Prerequisites
- A Laravel project (composer install --no-dev from composer.lock, then FrankenPHP serving public/ (php-server with the index.php fallback) reading PORT on the php-8.5 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 course creators data classes may be handled at all; this blueprint models public information only

## Tested Configuration
- **Template:** php-8.5
- **Runtime:** php
- **Size:** s-1vcpu-1gb
- **Install:** composer install --no-dev --prefer-dist --no-interaction --no-progress --optimize-autoloader
- **Start:** frankenphp php-server --listen :$PORT --root public

## Workflow Steps
1. **Model the course creators domain**: Create the tables course_groups, memberships, sessions, materials, uploads. Cohorts as course groups live in course_groups; keep the sensitive classes (learner progress and grades, recordings showing learners, payment status) out of this schema.
2. **Workflow step 1**: Model assets linked to their owning group or workspace.
3. **Workflow step 2**: Validate uploads and store them in the private bucket; link each object to its row.
4. **Workflow step 3**: Authorize downloads by membership.
5. **Workflow step 4**: Deploy and verify rejection of disallowed files and linked upload.
6. **Deploy**: Run the synchronous deploy once and read the result. Re-running with no change is a no-op.
   - *Command*: ample deploy . --name  --public --env S3_ENDPOINT=... --env S3_REGION=... --env S3_BUCKET=... --env S3_ACCESS_KEY_ID=... --env S3_SECRET_ACCESS_KEY=...
7. **Verify**: Run the pattern self-test(s) from the example (/p/browser-file-uploads) and your own acceptance checks for the course creators workflow.
   - *Command*: ample logs  --kind build

## Success Checks
- App responds on its public URL: Expect ample canary laravel patterns
- Browser-file-uploads self-test from the example: Expect to see the pattern fixture checks.

## Limitations
- The technical basis (browser file uploads on Laravel) was verified with the pattern fixture; the course creators 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. Recordings and progress data are personal data; materials are authorized per course group.
- Public content and synthetic examples only until actual data-handling requirements have been reviewed.
- Verified on the php-8.5 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**: Laravel 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. The blueprint's Course creators schema and workflow below build on that verified basis and were not separately executed.
