QueryForge is a TypeScript library that provides a flexible and type-safe way to compose SQL queries dynamically. With QueryForge, you can easily construct SELECT, INSERT, UPDATE, and DELETE queries using TypeScript code.

import QueryComposer from 'queryforge';
interface Casa {
quartos: number;
bairro: string;
rua: string;
}
// Create an instance of QueryComposer with the desired type
const queryComposer = new QueryComposer<Casa>();
// Example: Generating a SELECT query
const selectQuery = queryComposer
.startSelection('Casa')
.Select('quartos', 'bairro', 'rua')
.Where((item) => {
return item.quartos > 2 && item.bairro === '1';
})
.toString();
console.log(selectQuery);
// Output: SELECT quartos, bairro, rua FROM Casa WHERE quartos > 2 AND bairro = '1';
// Example: Generating an INSERT query
const insertQuery = queryComposer
.startInsertion('Casa')
.Insert('bairro', 'Paulista')
.Insert('quartos', 3)
.toString();
console.log(insertQuery);
// Output: INSERT INTO Casa SET (bairro, quartos) VALUES ('Paulista',3);
// Other examples for UPDATE and DELETE queries are also available.The main class responsible for composing SQL queries. It accepts a type parameter T representing the schema of the table.
startSelection(entity: string): ConstructorQuerySelectable<T>: Initialize a SELECT query for the specified entity.startUpdation(entity: string): ConstructorQueryUpdatable<T>: Initialize an UPDATE query for the specified entity.startDeletion(entity: string): ConstructorQueryDeletable<T>: Initialize a DELETE query for the specified entity.startInsertion(entity: string): ConstructorQueryInsertable<T>: Initialize an INSERT query for the specified entity.
