NestJS #34 - Interceptors | Intercept Request & Response | Aspect Oriented Programming | (Hindi)

Interceptors in NestJS provide us many capabilities by intercepting the Request and Response, unlike Middleware which run on Request only. We can bind extra logic before and after Route Handler Method Execution benefiting us from AOP (Aspect-Oriented programming). In addition to that, Interceptors help us to Override Method Behavior, Request Timeouts, and much more. In this video, we will explore the concept of AOP, Interceptors. Also we will see some use cases like Read-through Cache and Request Timeouts. ▬▬▬▬▬▬ 🔗 Links ▬▬▬▬▬▬ ► GitHub (Source code) : https://bit.ly/3QjSNcf ► NestJS - ArgumentsHost & ExecutionContext : https://youtu.be/5uau_mqTTtU ► NestJS - Exception Filters : https://youtu.be/z8SoEQ3daRM ▬▬▬▬▬▬ 📚 CHAPTERS ▬▬▬▬▬▬ 00:00 - Introduction 00:35 - AOP & Interceptor Concept 01:17 - Tasks Requirements 03:40 - Creating Interceptor - Intercepting Returned Result 07:37 - Using Interceptor 08:45 - Intercepting Incoming Request 10:03 - Binding Extra Logic - Storing in Cache 13:40 - Method Behaviour Overriding - Read-through Cache 16:53 - Method Exception Overriding - Intercept Exception 19:49 - Request Timeouts 22:06 - Errors Inside Interceptor 22:42 - Closing notes ▬▬▬▬▬▬ 🔖 RECOMMENDED COURSES ▬▬▬▬▬▬ 🎬 Angular In-Depth (Hindi) - https://bit.ly/34nHrBh 🎬 Angular Architecture - https://youtu.be/bRTiIRPU5A0 🎬 NestJS Framework | Backend Development (Hindi) - https://bit.ly/3titPk3 🎬 RxJS - The Practical Guide (Hindi) - https://bit.ly/3GBcXsf 🎬 RxJS - Promise vs Observable | A depth comparison - https://youtu.be/WD2LYXgevY8 🎬 RxJS - Introduction to Reactive programming - https://youtu.be/v0DtWGoLRmI ▬▬▬▬▬▬ CONNECT WITH ME 👋 ▬▬▬▬▬▬ 🐦 Twitter: https://twitter.com/akacomputerbaba 🏠 Discord: https://bit.ly/3Js25iy 👓 GitHub: https://github.com/cistroncoder 📧 Email: [email protected] 💙 Join this channel https://www.youtube.com/c/ComputerBabaOfficial ▬▬▬▬▬▬ 🎻 MUSIC ▬▬▬▬▬▬ 🎵 Fresh Start - Joakim Karud https://freesound.org ▬▬▬▬▬▬ # HASHTAGS ▬▬▬▬▬▬ #AmazingNestjs #nestjs #computer_baba #interceptors #nestjs_interceptor #middleware #middlewares #nestjs_guards #nestjs_pipes #data_transformation #microservices #dependency_injection #ioc_container #routing #nestjs_project #nodejs #rest_api #http #expressjs #fastify #graphql #mongodb #sql #typeorm #microservices #backend_development #javascript #typescript #rxjs #json
