semantqQL

CRUD Abstraction for Semantq Full Stack Apps (semantqQL)

A super lightweight, robust, and reusable JavaScript HTTP client class that abstracts standard CRUD (Create, Read, Update, Delete) operations with simple fetch API calls — designed to streamline REST API interactions in your full-stack SemantQL projects.

Installation

Install via npm:

npm install @semantq/ql

Import it into your project:

import smQL from '@semantq/ql';

Usage

Create an instance with the endpoint URL, HTTP method, request body (if any), and optional configuration:

const result = await new smQL(endpoint, method, body, options);

• endpoint: URL string of your API resource

• method: HTTP method string (GET, POST, PUT, PATCH, DELETE) — defaults to GET

• body: Request payload for methods like POST or PUT (default: null)

• options: Optional configuration object — supports:

  • headers — additional headers
  • log — boolean to enable/disable automatic console logging (default: true)

Automatic Logging

By default, semantQL.js automatically logs success or failure messages to the console for every request, showing HTTP method, status, and response data.

You do not need to manually log responses in your application code unless you disable logs explicitly:

await new smQL('http://localhost:3003/product/products', 'GET', null, { log: false });

Returned Result Object

The promise resolves to an object containing:

{
  status: number,       // HTTP status code
  ok: boolean,          // true if response.ok (status 2xx)
  data: any,            // Parsed JSON or plain text response body
  error?: string        // Error message if request failed
}

You can use this object directly without needing extra logging.

Examples: Common CRUD Operations

1. GET — Fetch all products

const data = await new smQL('http://localhost:3003/product/products');

//now you can do: console.log(data); 

2. POST — Create a new category

const newCategory = { name: 'Mobiles' };

const response = await new smQL('http://localhost:3003/category/categories', 'POST', newCategory);

3. PUT — Update an existing category

const updatedCategory = { name: 'Mobile Phones' };
const categoryId = 7;

const response = await new smQL(`http://localhost:3003/category/categories/${categoryId}`, 'PUT', updatedCategory);

4. DELETE — Delete a product (without logs)

const productId = 42;

const response = await new smQL(`http://localhost:3003/product/products/${productId}`, 'DELETE', null, { log: false });

Why Use semantQL.js?

This class serves as a simple CRUD abstraction layer within the full-stack SemantQL setup, allowing you to:

• Write clean, concise API calls without repeating boilerplate
• Handle JSON payloads and errors uniformly
• Have automatic logging out-of-the-box with the option to disable per request
• Plug and play with any REST API endpoint

It’s lightweight and designed with developer experience in mind.

Happy CRUDing. !!!
