MegaORM Utils

This package provides utility functions to validate whether a value is a MegaORM driver or a connection.

Installation

To install this package, run the following command:

npm install @megaorm/utils

Functions

isDriver(driver): Ensures that the given value is one of MegaORM's supported drivers: @megaorm/mysql, @megaorm/sqlite, or @megaorm/pg.

const { isDriver } = require('@megaorm/utils');

console.log(isDriver({})); // false

Returns true if the value is a valid MegaORM driver, false otherwise.

isMySQL(driver): Ensures that the given value is a @megaorm/mysql driver.

const { isMySQL } = require('@megaorm/utils');

console.log(isMySQL({})); // false

Returns true if the value is the MySQL driver, false otherwise.

isPostgreSQL(driver): Ensures that the given value is a @megaorm/pg driver.

const { isPostgreSQL } = require('@megaorm/utils');

console.log(isPostgreSQL({})); // false

Returns true if the value is the PostgreSQL driver, false otherwise.

isSQLite(driver): Ensures that the given value is a @megaorm/sqlite driver.

const { isSQLite } = require('@megaorm/utils');

console.log(isSQLite({})); // false

Returns true if the value is the SQLite driver, false otherwise.

isCon(connection): Ensures that the given value is a MegaConnection — a connection created by any MegaORM driver.

const { isCon } = require('@megaorm/utils');

console.log(isCon({})); // false

Returns true if the value is a MegaConnection, false otherwise.

isPendingCon(connection): Ensures that the given value is a MegaPendingConnection — a connection that could not be closed by MegaPool.

const { isPendingCon } = require('@megaorm/utils');

console.log(isPendingCon({})); // false

Returns true if the value is a MegaPendingConnection, false otherwise.

isPoolCon(connection): Ensures that the given value is a MegaPoolConnection — a connection created by MegaPool.

const { isPoolCon } = require('@megaorm/utils');

console.log(isPoolCon({})); // false

Returns true if the value is a MegaPoolConnection, false otherwise.

Usage Examples

const { isDriver, isSQLite, isCon } = require('@megaorm/utils');

const { SQLite } = require('@megaorm/sqlite');

// Create a driver instance
const driver = new SQLite(':memory:');

// Ensure it's an SQLite driver instance
if (isSQLite(driver)) {
  console.log('This is an SQLite driver!');
}

// Ensure it's a MegaORM driver instance (SQLite, PostgreSQL, MySQL)
if (isDriver(driver)) {
  console.log('This is a MegaORM driver!');
}

// Create a connection
driver.create().then((connection) => {
  // Ensure it's a MegaConnection
  if (isCon(connection)) {
    console.log('This is a MegaConnection!');
  }
});
