# NestJS Best Practices Comprehensive best practices for NestJS development. ## Core Principles 1. **Always use constructor injection** - Never use property injection 2. **Use DTOs for data transfer** - Define interfaces for request/response 3. **Implement proper error handling** - Use exception filters 4. **Validate all inputs** - Use validation pipes 5. **Keep modules focused** - Single responsibility principle 6. **Use environment variables** - Never hardcode credentials 7. **Write comprehensive tests** - Unit and integration tests 8. **Use transactions for complex operations** - Maintain data consistency 9. **Implement proper logging** - Use interceptors for cross-cutting concerns 10. **Use type safety** - Leverage TypeScript features ## Database Best Practices - **Connection pooling** - Always use pooling for production workloads - **Index frequently queried columns** - Improve query performance - **Use migrations for schema changes** - Never modify schema manually - **Implement soft deletes** - Preserve data history - **Use transactions** - Ensure data consistency ## Security Best Practices - **Never expose stack traces** - In production error responses - **Validate all inputs** - Prevent injection attacks - **Use parameterized queries** - Drizzle does this automatically - **Implement rate limiting** - Prevent abuse - **Use HTTPS** - Encrypt data in transit ### Install Drizzle and Gel Packages Source: https://orm.drizzle.team/docs/get-started/gel-new Installs the necessary Drizzle ORM and Gel packages, along with development dependencies like Drizzle Kit and tsx. ```bash npm i drizzle-orm gel npm i -D drizzle-kit tsx ``` ```bash yarn add drizzle-orm gel yarn add -D drizzle-kit tsx ``` ```bash pnpm add drizzle-orm gel pnpm add -D drizzle-kit tsx ``` ```bash bun add drizzle-orm gel bun add -D drizzle-kit tsx ``` -------------------------------- ### Install Drizzle ORM and Drizzle Kit with bun Source: https://orm.drizzle.team/docs/get-started/bun-sql-new Installs Drizzle ORM and Drizzle Kit using the Bun runtime's package manager, including types for Bun. ```bash bun add drizzle-orm bun add -D drizzle-kit @types/bun ``` -------------------------------- ### Install Drizzle ORM and Drizzle Kit with npm Source: https://orm.drizzle.team/docs/get-started/bun-sql-new Installs the necessary Drizzle ORM package for database operations and Drizzle Kit for schema management and migrations using npm. ```bash npm i drizzle-orm npm i -D drizzle-kit @types/bun ``` -------------------------------- ### Install Drizzle ORM and Drizzle Kit with yarn Source: https://orm.drizzle.team/docs/get-started/bun-sql-new Installs the Drizzle ORM and Drizzle Kit packages using yarn, including the types for Bun. ```bash yarn add drizzle-orm yarn add -D drizzle-kit @types/bun ``` -------------------------------- ### Install Drizzle Packages with bun Source: https://orm.drizzle.team/docs/get-started/planetscale-new Installs the necessary Drizzle ORM packages, the PlanetScale database driver, dotenv for environment variables, and Drizzle Kit with tsx for development. ```bash bun add drizzle-orm @planetscale/database dotenv bun add -D drizzle-kit tsx ``` -------------------------------- ### Install Drizzle ORM and Drizzle Kit with pnpm Source: https://orm.drizzle.team/docs/get-started/bun-sql-new Installs Drizzle ORM and Drizzle Kit, along with Bun types, using the pnpm package manager. ```bash pnpm add drizzle-orm pnpm add -D drizzle-kit @types/bun ``` -------------------------------- ### Install Drizzle Packages with pnpm Source: https://orm.drizzle.team/docs/get-started/planetscale-new Installs the necessary Drizzle ORM packages, the PlanetScale database driver, dotenv for environment variables, and Drizzle Kit with tsx for development. ```bash pnpm add drizzle-orm @planetscale/database dotenv pnpm add -D drizzle-kit tsx ``` -------------------------------- ### Install Drizzle Packages with npm Source: https
