Repository Initialization and Module Configuration

The objective is to scaffold a convention-driven REST API structure using the Iris web libray. This foundation consolidates recurring patterns to accelerate subsequent feature implementation.

Create a remote repository through your preferred version control platform. Clone the empty repository into a dedicated local workspace directory.

# Create workspace and initialize repository
mkdir api-framework-base
cd api-framework-base
git init
git remote add origin https://github.com/yourusername/api-framework-base.git

Bootstrap the Go module system and fetch the framework dependency:

go mod init api-framework-base
go get github.com/kataras/iris/v12@latest

Application Antry Point Design

Generate the primary bootstrap file. The following implementation demonstrates route grouping, automatic response compression, and structured JSON payload binding.

package main

import (
	"log"

	"github.com/kataras/iris/v12"
)

type CatalogEntry struct {
	Identifier int    `json:"identifier"`
	Title      string `json:"title"`
	Status     string `json:"status"`
}

func registerRoutes(app *iris.Application) {
	// Enable global response compression
	app.Use(iris.Compression)

	// Establish a namespaced route group
	ns := app.Party("/catalog")
	{
		ns.Get("/", retrieveAll)
		ns.Post("/", publishItem)
	}
}

func retrieveAll(ctx iris.Context) {
	data := []CatalogEntry{
		{Identifier: 101, Title: "Quantum Modules", Status: "active"},
		{Identifier: 102, Title: "Neural Connectors", Status: "archived"},
		{Identifier: 103, Title: "Data Mesh Services", Status: "active"},
	}

	ctx.StatusCode(iris.StatusOK)
	ctx.JSON(data)
}

func publishItem(ctx iris.Context) {
	var incoming CatalogEntry

	if err := ctx.ReadJSON(&incoming); err != nil {
		log.Printf("Binding error: %v", err)
		ctx.StatusCode(iris.StatusBadRequest)
		ctx.Stop()
		return
	}

	incoming.Identifier = generateSequentialID()
	incoming.Status = "pending_review"

	log.Printf("Ingested payload: %+v", incoming)

	ctx.StatusCode(iris.StatusCreated)
	ctx.JSON(map[string]interface{}{
		"message": "item registered successfully",
		"result":  incoming,
	})
}

func generateSequentialID() int {
	return 1004
}

func main() {
	binder := iris.New()
	registerRoutes(binder)

	listenAddress := ":8090"
	log.Printf("API gateway bound to %s", listenAddress)
	if err := binder.Listen(listenAddress); err != nil {
		log.Fatalf("Runtime failure: %v", err)
	}
}

Service Execution and Endpoint Validation

Compile and launch the service directly from the commend line:

go run main.go

A successful initialization prints the binding interface. Verify routing and serialization by issuing a request through a browser or CLI tool:

GET http://127.0.0.1:8090/catalog

Receiving a well-formed JSON array confirms that the middleware pipeline, route table, and context managers are operating correctly.
