Host digital downloads with Laravel: relational catalog data | Ample

WHAT WAS VERIFIED

Verified on Laravel: an optimistic version check and an event row written in the same transaction, a stale update rejected, and a history query over the application-owned events (history=2 conflict=rejected).

INFRASTRUCTURE

What it needs

• 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.)

PREREQUISITES

Before you start

• A Laravel project that builds and starts with the documented commands (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 at runtime (auto-provisioned when omitted, or supplied with --env)
• An Ample account token with servers:write, databases:read

STEP BY STEP

How to do it

1. 1

Build and start

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 server must bind 0.0.0.0 on PORT.

2. 2

Implement the pattern on PostgreSQL

The fixture's module implements transactional workflows: an optimistic version check and an event row written in the same transaction, a stale update rejected, and a history query over the application-owned events (history=2 conflict=rejected). Copy the approach into your schema; keep migrations idempotent and run them with --release-command.

3. 3

Deploy

Run the synchronous deploy once and read the result (exit 0 live, 1 failed, 2 blocked). Re-running with no change is a no-op.

ample deploy . --name <app-name> --public

4. 4

Verify

Fetch the live URL and the pattern self-test route(s) (/p/transactional-workflows) from the example; then run your own checks. On failure read ample logs <deployment_id> --kind build then --kind runtime.

ample logs <deployment_id> --kind build

EXAMPLES

Tested examples

• Laravel pattern fixture (tests/deploy-canaries/laravel-patterns): Multi-pattern Laravel app whose transactional workflows module was checked live; the module is under tests/deploy-canaries/_pattern-modules.

SUCCESS CHECKS

How to know it worked

• app responds on its public URL (/ on the live URL, expect ample canary laravel patterns)
• transactional-workflows self-test (/p/transactional-workflows on the live URL, expect tx=ok history=2 conflict=rejected)

COST

Cost estimate

Estimated 10.00 USD per month (size prices from pricing.toml at build revision 515b7316fc6e5a81679407ae0c811146ceb2c5c7).

• 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.
