Top 6 Nest.js Caching Libraries for Improved Performance

NestJS is popular. It is for building scalable server-side apps in Node.js. It is also for building maintainable apps.  

Several essential libraries complement NestJS, enhancing its capabilities for developers. For instance, nestjs-redis adds Redis client functionalities to NestJS. It offers simple caching. It has pub/sub messaging for real-time communication and support for distributed locks. 

• Node-cache-manager provides flexible caching options. It supports many storage types, time-based end, and customizable invalidation strategies.  
• With nestjs-cqrs-starter, developers can add the Command Query Responsibility Segregation (CQRS) architecture. It uses event sourcing and command and event buses for fast system communication.  
• nestjs-pino offers high-performance logging with Pino, featuring customizable formats and seamless integration.  
• nestjs-typeorm-paginate simplifies pagination in TypeORM queries, enhancing data handling in NestJS applications. 

Finally, nestjs-typegoose simplifies MongoDB modeling with TypeScript. It ensures type-safe queries and integrates with NestJS's dependency injection. These libraries enrich NestJS development. They empower developers to build robust, efficient, and scalable apps with ease.
