Validator Toolkit

A comprehensive toolkit for data validation in JavaScript.

Description

Validator Toolkit provides a set of tools and utilities to validate various types of data, including strings, numbers, arrays, and objects. Whether you're building a web application, API, or any other software that deals with user input, Validator Toolkit can help ensure that your data meets the required criteria.

Installation and Usage

Server-side

To install Validator Toolkit using npm, run the following command:

npm install ds-validator-toolkit

Browser Usage (ESM)

You can use Validator Toolkit directly in the browser without installing it by importing the desired functions from the unpkg.com CDN:

<script type="module">
  // inporting package from the URL
  import { VALIDATE_STRING } from "https://unpkg.com/ds-validator-toolkit/dist/index.mjs";

  let name = VALIDATE_STRING.validateString("Mareline", {
    // options...
  });

  console.log(name);
</script>

ES6 Modules

If you're using ES6 modules in your project, you can import the desired functions from the package:

import {
  _STR_,
  VALIDATE_STRING,
} from "./node_modules/ds-validator-toolkit/dist/index.mjs";

Add this line in your html file

<script src="./app.js" type="module"></script>

Webpack Integration

If you're using Webpack, you can easily integrate Validator Toolkit into your project. Follow these steps:

1- Initialize a new npm project using:

npm init -y

2- Install the required dependencies:

npm install webpack webpack-cli babel-loader @babel/core @babel/preset-env --save-dev

3-Create a webpack.config.js file with the following configuration:

const path = require('path');

module.exports = {
    entry: './src/index.js',
    output: {
        path: path.resolve(__dirname, 'dist'),
        filename: 'bundle.js',
    },
    module: {
        rules: [
            {
                test: /\.(js|jsx)$/,
                exclude: /node_modules/,
                use: {
                    loader: 'babel-loader',
                    options: {
                        presets: ['@babel/preset-env'],
                    },
                },
            },
        ],
    },
};

</script>

4- Create a src folder and an index.js file within it. You can import the desired functions from the package in this file:

import { _STR_, VALIDATE_STRING } from "ds-validator-toolkit";

5- In your HTML file, include the bundled JavaScript file:

<script src="./dist/bundle.js" type="module"></script>

6- Run npm run build to generate the bundled JavaScript file (dist/bundle.js).

With these steps, you should be able to use Validator Toolkit in your Webpack project.

Example 1: Using VALIDATE_STRING

Here's an example demonstrating the VALIDATE_STRING function with various options:

const name = "Chloe";
const result = VALIDATE_STRING(name, {
  // Options
  isRequired: true,
  minStringLength: 10,
  maxStringLength: 20,
  // ...

  // Error Messages
  isStringError: "Input must be a string.",
  lengthError: "Input length must be between 10 and 20 characters.",
  // ...
});

console.log(result); // { isValid: false, message: "Input length must be between 10 and 20 characters." }

This example showcases the VALIDATE_STRING function with the specified options and custom error messages.

Example 2: Using STR Class

const name = "flower";

// Check if the string is required
_STR_.isRequired(name, true);

// Check if the string contains blacklisted words
const result = _STR_.containsBlacklistedWord(name, ["flower", "garden"]);

console.log(result); // { isValid: false, message: "Name contains blacklisted words." }

The STR class provides various functions for string validation, making it easy to perform specific checks on strings.

What's New

available options:

isRequired, maxValue, minValue, isInteger, allowNegative = true, allowPositive = true, allowZero = true, onlyDecimal, maxDecimalPlaces, minDecimalPlaces, allowExponent, onlyBinary thousandSeperator customThousandSeperator customValidationFn (NEW!!!)

Future

allowCurrencySymbol
