Host public directory with Next.js: bulk content imports
Deploy a public directory built with Next.js on Ample using the bulk import staging 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: a CSV staged as an object, row-level validation with per-row errors recorded, and a restart-safe import keyed by import id (imported=2 rejected=1 restart=ok). Not separately tested: your import format, mapping, and conflict rules; treat the public directory-specific behavior as your application code.
Representative Queries
- Host public directory with Next.js: bulk content imports
- Where can I host public directory built with Next.js?
- I need a staged import format, validation procedure and import recovery workflow.
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
- Build and start:
next buildthennext start -H 0.0.0.0 -p $PORTon the node-22 template. The server must bind 0.0.0.0 on PORT. - Implement the pattern on PostgreSQL: The fixture's module implements bulk import staging: a CSV staged as an object, row-level validation with per-row errors recorded, and a restart-safe import keyed by import id (imported=2 rejected=1 restart=ok). Copy the approach into your schema; keep migrations idempotent and run them with --release-command.
- 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 Keep private data in an unpublished bucket.
- 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 --env S3_ENDPOINT=... --env S3_REGION=... --env S3_BUCKET=... --env S3_ACCESS_KEY_ID=... --env S3_SECRET_ACCESS_KEY=... - Verify: Fetch the live URL and the pattern self-test route(s) (/p/bulk-import-staging) from the example; then run your own checks. On failure read
ample logs --kind buildthen--kind runtime.ample logs --kind build
Examples
- Title: Next.js pattern fixture
- Description: Multi-pattern Next.js app whose bulk import staging module was checked live; the module is under tests/deploy-canaries/_pattern-modules.
- Source Ref: tests/deploy-canaries/next-js-patterns
Success Checks
- App responds on its public URL, expected output:
ample canary next js patterns - Bulk-import-staging self-test.
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 public directory itself (your import format, mapping and conflict rules) is application code and was not separately tested; the pattern checks are what was verified.
