# Host community forum with Next.js: tenant-scoped workspaces

## Summary
Deploy a community forum built with Next.js on Ample using the multi-tenant relational data 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. Verified on Next.js: a tenant column on every row and query, with a cross-tenant read returning nothing (tenant_isolation=ok). Not separately tested: your tenant model, membership and per-tenant authorization; treat the community forum-specific behavior as your application code.

## Representative Queries
- Host community forum with Next.js: tenant-scoped workspaces
- Where can I host Community forum built with Next.js?
- I need an explicit tenant model and application-enforced tenant isolation tests.

## Resource Requirements
- **Compute**
- **Postgres**

## Infrastructure Requirements
### Compute
- **Status**: Verified  
- **Summary**: Apps run in isolated x86_64 Firecracker microVMs that auto-pause when idle and wake on request; sizes are the priced VM sizes.

### Postgres
- **Status**: Verified  
- **Summary**: Managed PostgreSQL 16 runs in its own microVM and is auto-provisioned when an app needs a database and no DATABASE_URL is supplied.

## Framework
Next.js

## Workload
Community forum

## Prerequisites
- A Next.js project that builds and starts with the documented commands (next build then next start -H 0.0.0.0 -p $PORT on the node-22 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

## 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 multi-tenant relational data: a tenant column on every row and query, with a cross-tenant read returning nothing (tenant_isolation=ok). Copy the approach into your schema; keep migrations idempotent and run them with --release-command.
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  --public`
4. **Verify**  
   Fetch the live URL and the pattern self-test route(s) (/p/multi-tenant-relational-data) from the example; then run your own checks. On failure read `ample logs  --kind build` then `--kind runtime`.
   `ample logs  --kind build`

## Examples
### Next.js pattern fixture
- **Description**: Multi-pattern Next.js app whose multi-tenant relational data module was checked live; the module is under tests/deploy-canaries/_pattern-modules.
- **Source Reference**: tests/deploy-canaries/next-js-patterns

## Success Checks
- **App responds on its public URL**  
  - **Path**: /  
  - **Expectation**: ample canary next js patterns
- **Multi-tenant-relational-data self-test**  
  - **Path**: /p/multi-tenant-relational-data  
  - **Expectation**: tenant_isolation=ok

## 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 community forum itself (your tenant model, membership and per-tenant authorization) is application code and was not separately tested; the pattern checks are what was verified.

## Cost Estimate
- **Currency**: USD  
- **Monthly Amount**: 10.0  
- **Components**:
  - App server: **Size**: s-1vcpu-1gb, **Monthly Amount**: 5.0
  - Managed PostgreSQL database: **Size**: s-1vcpu-1gb, **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
- **Canary Run**: Next.js pattern fixture deployed on Ample; checks passed for multi-tenant-relational-data.
