v5.0.0

Features

• core: support async lifecycle hooks (OnModuleInit and OnModuleDestroy) #569
• core: HTTP server independence, fastify integration (FastifyAdapter)
• core: allow binding global interceptors, filters, pipes, and guards from any module. Example:

{
  provide: APP_INTERCEPTOR,
  useClass: LoggerInterceptor,
}

• core: @UseGuards(), @UsePipes(), @UseFilters(), and @UseInterceptors() extend metadata, instead of overriding existing one
• core: dependency injection everywhere (pipes, filters, interceptors, and guards)
• core: pass ArgumentsHost to exception filters (ability to access each argument)
• core: pass enhanced ExecutionContext to both interceptors and guards (ability to access each argument and execution context)
• microservices: rewrite existing transporters (TCP, Redis), provide new strategies: Nats, MQTT, gRPC
• all: improve execution context performance (http, ws, microservices)

Bug Fixes

• common: incorrent multer dependency #532
• core: hanging NestApplicationContext process #503
• microservices: concurrency issues (both TCP and Redis transporters) #505

Improvements

• all: remove reflect-metadata peer dependency #563
• all: upgrade RxJS to 6.0.0
• all: move to Node.js >= 8.9.0 (TypeScript target es2017)
• core: more descriptive exceptions (circular dependency) #493
• core: Nest container compatible with useContainer() (class-validator and typeorm packages) #528
• core: remove static dependencies (webpack compatibility)
• websockets: @WebSocketGateway() takes options argument that is passed to socket.io instance #508

Deprecations

• common: deprecate @Component(), @Middleware(), @Interceptor(), @Pipe(), and @Guard() decorators (use @Injectable() instead)
• common: removed ExpressMiddleware (use MiddlewareFunction)
• core: deprecate modules: [] property (use imports: [] instead)
• core: deprecate components: [] property (use providers: [] instead)
• core: removed MiddlewaresConsumer (use MiddlewareConsumer)

Notes

• move from traditional express middleware model: each middleware is solely bounded to a particular path, regardless of the request method
