# 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). ## Infrastructure requirements - Verified Compute: Apps run in isolated x86_64 Firecracker microVMs that auto-pause when idle and wake on request; sizes are the priced VM sizes. - Verified 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. - Verified 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 ## Exact 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` ## Steps 1. **Model the course creators domain.** Create the tables course_groups, memberships, sessions, materials, uploads. Cohorts as course groups lives 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 a linked upload 6. **Deploy.** Run the synchronous deploy once and read the result. Re-running with no change is a no-op. ``` 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. ``` ample logs --kind build ``` ## Tested examples - **Laravel pattern fixture** (tests/deploy-canaries/laravel-patterns): Verified browser file uploads basis for this blueprint. ## Success checks - app responds on its public URL (`/` on the live URL, expect ample canary laravel patterns) - browser-file-uploads self-test from the example (`/p/browser-file-uploads` on the live URL, expect 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 verified. ## 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 2026-09-20T20:36:21Z at revision `118ad1c6d7d23d4c2ce069254bab9ec9d37cd57b-dirty (CLI 118ad1c)`: Laravel pattern fixture deployed on Ample (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); 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 Course creators schema and workflow below build on that verified basis and were not separately executed.
