A progressive Node.js framework for building efficient and scalable server-side applications.

Description

Nest framework TypeScript starter repository.

Database Migrations

Schema changes are managed exclusively through TypeORM migrations. Auto-sync (synchronize) is disabled in all environments to prevent accidental schema changes.

# Generate a migration from entity changes
$ npm run migration:generate

# Apply pending migrations
$ npm run migration:run

# Revert the last migration
$ npm run migration:revert

# Dry-run: check for pending migrations without applying (also runs in CI)
$ npm run migration:dryrun

Note: Never rely on synchronize: true in any environment. Always generate and commit migrations alongside entity changes.

Data retention

Financial records now use soft deletes instead of hard deletes for the primary transaction, FX trade, and referral entities. Deletions should update the deletedAt timestamp so the data remains available for audit, reconciliation, and retention workflows.

Operational logging

Slow database queries are emitted as JSON log entries with the event name typeorm.slow_query. The payload includes these fields:

• thresholdMs
• durationMs
• query
• parameters

Set SLOW_QUERY_THRESHOLD_MS to adjust the slow-query warning threshold. The default is 1000 milliseconds.

Deployment

When you're ready to deploy your NestJS application to production, there are some key steps you can take to ensure it runs as efficiently as possible. Check out the deployment documentation for more information.

If you are looking for a cloud-based platform to deploy your NestJS application, check out Mau, our official platform for deploying NestJS applications on AWS. Mau makes deployment straightforward and fast, requiring just a few simple steps:

$ npm install -g @nestjs/mau
$ mau deploy

With Mau, you can deploy your application in just a few clicks, allowing you to focus on building features rather than managing infrastructure.
