Introduction to ns-api: A Comprehensive Guide for Developers

The ns-api is a powerful tool for developers looking to integrate third-party functionalities into their web applications seamlessly. It offers a wide array of endpoints and services, making development quicker and more efficient.

Getting Started with ns-api

Before diving into the various functionalities, let’s start with how you can set up the ns-api in your project:

  
    // Installation
    npm install ns-api
    
    // Importing the library
    const nsApi = require('ns-api');
    
    // Initialization
    const api = new nsApi({
      apiKey: 'YOUR_API_KEY'
    });
  

User Management APIs

Create a User

The following example demonstrates how to create a new user using ns-api

  
    api.createUser({
      username: 'john_doe',
      email: 'john_doe@example.com',
      password: 'securePassword'
    }).then(response => {
      console.log(response.data);
    }).catch(error => {
      console.error(error);
    });
  

Get User Information

Fetch information about a specific user:

  
    api.getUser('john_doe')
      .then(response => {
        console.log(response.data);
      })
      .catch(error => {
        console.error(error);
      });
  

Product Management APIs

Fetch All Products

Retrieve a list of all products:

  
    api.getProducts()
      .then(response => {
        console.log(response.data);
      })
      .catch(error => {
        console.error(error);
      });
  

Create a New Product

Add a new product to the catalog:

  
    api.createProduct({
      name: 'New Product',
      price: 99.99,
      description: 'This is a new product'
    }).then(response => {
      console.log(response.data);
    }).catch(error => {
      console.error(error);
    });
  

Order Management APIs

Create an Order

API to create a new order:

  
    api.createOrder({
      userId: '123',
      productId: '456',
      quantity: 2
    }).then(response => {
      console.log(response.data);
    }).catch(error => {
      console.error(error);
    });
  

Get Order Details

Fetch details of an existing order:

  
    api.getOrder('789')
      .then(response => {
        console.log(response.data);
      })
      .catch(error => {
        console.error(error);
      });
  

Building an Application with ns-api

Here’s an example of a simple Node.js application that utilizes several ns-api methods:

  
    const express = require('express');
    const nsApi = require('ns-api');
    
    const app = express();
    const api = new nsApi({ apiKey: 'YOUR_API_KEY' });
    
    app.get('/users/:username', (req, res) => {
      api.getUser(req.params.username)
        .then(response => res.json(response.data))
        .catch(error => res.status(500).json({ message: error.message }));
    });
    
    app.post('/products', (req, res) => {
      api.createProduct(req.body)
        .then(response => res.json(response.data))
        .catch(error => res.status(500).json({ message: error.message }));
    });
    
    app.listen(3000, () => {
      console.log('Server is running on port 3000');
    });
  

With the ns-api, you can build robust and scalable web applications. The examples provided here are just the beginning. Numerous more functionalities are available, which you can explore in the official documentation.
