@ssibrahimbas/query

A fast, synchronized and dynamic query builder package.

What is?

In short, the query builder. You can write complex and parameterized queries fast, plain and dynamically using the Query class, which uses the chain of responsibility pattern!

Motivation

Generally, adding parameters to queries and parsing objects increases the distance of us as software developers to sql. This package was influenced by mongoose's Query class, aiming to make it usable in SQL databases, and that's what it ultimately does.

Run it on the drive you want! Sequelize can work with postgresql or any driver. All it needs is a driver that accepts sql code!

Looking forward to your pull requests and issues to make this package better.

Finally, all functions are gesture tested.

Installation

To include this package in your project, run the following command:

npm install @ssibrahimbas/query

or with yarn

yarn add @ssibrahimbas/query

And try this:

import { Query } from "@ssibrahimbas/query"

console.log(Query.table("users").getAll())

// SELECT * FROM users

ISsiQuery

Abstract of the Query class. If you wish, you can use as follows:

import { ISsiQueue, SsiQuery } from "@ssibrahimbas/query"

const Query : ISsiQuery = new SsiQuery();

Although this doable, it is memory redundant as the new key is constantly used. The Queue class has been developed to reset itself after each query. So you can use it with peace of mind as follows:

import { Query } from "@ssibrahimbas/query"

Functions

table

It is used to declare a table in SQL.

Abstract:

table(table: string | Array<string>) : ISsiQuery;

Example:

import { Query } from "@ssibrahimbas/query"

const query : string = Query.table("users").getAll();

// SELECT * FROM users

Using arrays:

import { Query } from "@ssibrahimbas/query"

const query : string = Query.table(["users", "products"]).analyze();

// ANALYZE TABLE users, products

select

Select the fields to use for the query

Abstract:

select(fields: Record<string,string> | Array<Record<string, string>> | string | Array<string>) : ISsiQuery;

Example:

import { Query } from "@ssibrahimbas/query"

const query : string = Query.table("users").select("id").getAll();

// SELECT id FROM users

Using arrays:

import { Query } from "@ssibrahimbas/query"

const query : string = Query.table("users").select(["id As userId", "name As userName"]).analyze();

// SELECT id As userId, name As userName FROM users

Using Records:

import { Query } from "@ssibrahimbas/query"

const data = { Id: "userId", FirstName: "firstName" };
const query : string = Query.table("users").select(data).getAll();

// SELECT Id AS userId, FirstName AS firstName FROM users

Using Records With Arrays:

import { Query } from "@ssibrahimbas/query"

const data: Array<Record<string, string>> = [
  { Id: "userId" },
  { FirstName: "firstName" },
];
const query : string = Query.table("users").select(data).getAll();

// SELECT Id AS userId, FirstName AS firstName FROM users
