How to Use Wire 0.5 for Dependency Injection with Go 1.24 and gRPC 1.60

Dependency injection (DI) simplifies managing complex object graphs in Go applications, and Wire 0.5 is a compile-time DI tool that eliminates runtime overhead. Combined with Go 1.24's performance improvements and gRPC 1.60's enhanced streaming support, Wire streamlines building modular, testable gRPC services. This guide walks through a complete implementation from scratch.

Prerequisites

Go 1.24 or later installed

Protocol Buffers compiler (protoc) v3.21+

protoc-gen-go v1.32+ and protoc-gen-go-grpc v1.3+

Wire CLI v0.5 installed (go install github.com/google/wire/cmd/ [email protected] )

Basic familiarity with Go interfaces and gRPC concepts

Step 1: Initialize Go Module

Create a new project directory and initialize a Go module:

go mod init github.com/example/grpc-wire-demo cd grpc-wire-demo

Enter fullscreen mode

Exit fullscreen mode

Step 2: Define gRPC Service with Protocol Buffers

Create a proto directory and add a user service…
