Use Go language to build npm packages and break through technical boundaries

You can build and publish NPM packages using Go by following these steps: Create a Go project directory containing a main.go file. Write Go code in main.go. Create a package.json file to define package metadata. Use the go build command to compile Go code into JavaScript modules. Run the npm publish command to publish the package to NPM.

Use Go to build npm packages and break through technical boundaries

Introduction
The Go language is powerful and suitable for various scenarios. Includes building NPM packages. This article will guide you to build and publish an NPM package using Go language.

Prerequisites

• Install Go language (version 1.13 or above)
• Install npm
• Node.js environment ( Version 10 or above)

Step 1: Create a Go project
Create a new directory to store your package source code, and create a main.go document.

mkdir my-npm-package
cd my-npm-package
touch main.go

Step 2: Write Go code
In the main.go file, write your Go code. For example, use the greeting method to return a greeting:

package main

import "fmt"

func greeting(name string) string {
    return fmt.Sprintf("Hello, %s!", name)
}

Step 3: Create a package.json file
Create a package.json file to define your NPM package.

{
  "name": "my-npm-package",
  "description": "A Go library for greeting",
  "version": "1.0.0",
  "main": "main.go",
  "scripts": {
    "start": "go run main.go",
    "build": "go build -o index.js -ldflags=\"-s -w\""
  }
}

Step 4: Compile Go code
Run the go build command to compile your Go code into a JavaScript module.

go build -o index.js -ldflags="-s -w"

Step 5: Publish to NPM
Publish your package to NPM by running the following command:

npm publish

Practical case: Node .js application
Install your package using NPM:

npm install my-npm-package

Use your package in your Node.js application:

const myPackage = require('my-npm-package');

console.log(myPackage.greeting('John')); // Hello, John!
