Introduction This is a comprehensive page about the technologies I have shared in series format. You can view brief introductions and links to directly access each series you are interested in. In the field of software development, to deploy a product from the initial idea to its release, the standard process typically involves several stages as follows: Database : Designing and implementing the database according to business requirements, storing data during the system's operation. Backend : Handling the main logic of the system, communicating with the database and services. Frontend : Building the interface for users to interact with the system, which could be a desktop, mobile, or web application. This usually includes implementing UI/UX and integrating APIs from the backend. DevOps : Deploying the system for use, which can be done on a server or in the cloud. Testing : Applying testing methods to ensure the product meets the standards for release. Of course, these are just stan...

Guide to integrating NextJS with gRPC and NestJS via HTTP/2

Image
Introduction gRPC is a high-performance RPC (Remote Procedure Call) framework developed by Google, using Protocol Buffers (protobuf) as the interface definition language and data serialization format. Unlike traditional REST which uses text (JSON), gRPC transmits data in binary format to optimize payload size and processing speed. In particular, gRPC operates based on HTTP/2, providing outstanding advantages such as: Multi-plexing (sending multiple concurrent requests over a single connection), Header Compression, and Server Push, helping to reduce latency and increase bandwidth for microservices systems. In this article, I will use NextJS for the frontend and act as a BFF (Backend For Frontend) as a proxy server to aggregate information and communicate via HTTP/2 gRPC with the NestJS server. Our connection will be as follows: Frontend connects to NextJS proxy server using restful api HTTP/1.1, NextJS connects to NestJS using gRPC via HTTP/2, we need a NextJS middleware to handle it, n...
