## Host CRM with Next.js: Downloadable Reports

Deploy a CRM built with Next.js on Ample using the generated downloads pattern. Compute runs the app in an isolated microVM behind a public HTTPS URL; a managed PostgreSQL 16 database is auto-provisioned and injected as DATABASE_URL. A private S3-compatible bucket holds objects with credentials delivered as encrypted environment variables. Verified on Next.js: an export query rendered to a CSV artifact stored with metadata in a private bucket and returned only to an authorized caller (401 without token, export=ok rows=3). Not separately tested: your export formats, retention policy, and entitlement model; treat the CRM-specific behavior as your application code.

### Representative Queries
- Host CRM with Next.js: downloadable reports
- Where can I host a CRM built with Next.js?
- I need an export query, generated artifact retention, and authorized download flow.

### Resource Requirements
- `primitive:compute`
- `primitive:postgres`
- `primitive: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.

### Workflow Steps
1. **Build and Start**: `next build` then `next start -H 0.0.0.0 -p $PORT` on the node-22 template. The server must bind 0.0.0.0 on PORT.
2. **Implement the Pattern on PostgreSQL**: The fixture's module implements generated downloads: an export query rendered to a CSV artifact stored with metadata in a private bucket and returned only to an authorized caller (401 without token, export=ok rows=3). Copy the approach into your schema; keep migrations idempotent and run them with `--release-command`.
3. **Wire Object Storage**: Create the bucket(s), then pass endpoint, region, bucket, and keys as `--env` values. Use path-style addressing. Keep private data in an unpublished bucket.
4. **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.
   - Command: `ample deploy . --name --public --env S3_ENDPOINT=... --env S3_REGION=... --env S3_BUCKET=... --env S3_ACCESS_KEY_ID=... --env S3_SECRET_ACCESS_KEY=...`
5. **Verify**: Fetch the live URL and the pattern self-test route(s) (/p/generated-downloads) from the example; then run your own checks. On failure read `ample logs --kind build` then `--kind runtime`.
   - Command: `ample logs --kind build`

### Success Checks
- **App responds on its public URL**: `http_get` - Path: `/`, Expect: `ample canary next js patterns`
- **Generated-downloads self-test**: `http_get` - Path: `/p/generated-downloads`, Expect: `export=ok rows=3 (with ?token=...; 401 without)`

### Limitations
- Verified on the node-22 template at s-1vcpu-1gb with the example fixture; other sizes, templates, and Next.js major versions are not verified.
- The CRM itself (your export formats, retention policy, and entitlement model) is application code and was not separately tested; the pattern checks are what's verified.
- Region, compliance attestations, and request-duration limits are unknown and not claimed.
- Apps auto-pause when idle and wake on the next request; always-on is an operator setting, not a plan feature.
- Managed PostgreSQL 16 only; extensions, connection limits, and backup or restore procedures are not verified; apps and their databases are placed together.
- PutObject and GetObject with path-style addressing are verified; multipart upload, listing, presigned URLs, and lifecycle rules are not.

### Cost Estimate
- **Currency**: USD
- **Monthly Amount**: 10.0
- **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.

### Examples
- **Next.js Pattern Fixture**: Multi-pattern Next.js app whose generated downloads module was checked live; the module is under tests/deploy-canaries/_pattern-modules. 
  - **Source Reference**: tests/deploy-canaries/next-js-patterns

### Evidence Summary
- **Canary Run**: Next.js pattern fixture deployed on Ample (next build then next start -H 0.0.0.0 -p $PORT on the node-22 template); checks passed for generated-downloads and configuration-secrets. Pattern proof: an export query rendered to a CSV artifact stored with metadata in a private bucket and returned only to an authorized caller (401 without token, export=ok rows=3).
