🔍 TypeChecker

An advanced Type Checker that checks and handles type for the param name on your function built to make nodejs module creating easy. Both TypeScript and JavaScript.

🚀 Features

- Easy to code
- Zero dependencies
- Light weight module
- Make type-checking easy
- Error handler

💻 Installation

NPM:

``sh
npm install type-checker-handler
`

Yarn:

`sh
yarn add type-checker-handler
`

📝 How to use

Using Type Checker is very easy
Only 1-2 lines code

Example usage (TypeScript):

`ts
import { JsTypes, typeCheck } from "type-checker-handler";

const aFunction = (msg: string, ...optional: any[]) => {
typeCheck({ paramName: msg, expectedType: JsTypes.String });
let output = msg;

if (optional.length > 0) {
output += optional.join(" ");
}

return output;
};

export { aFunction };
`

If the user provided parameter type is not same as the function's required type it will throw a \TypeError\

Example Usage (JavaScript):

`js
const { JsTypes, typeCheckJs } = require("type-checker-handler");

const aFunction = (msg, ...optional) => {
typeCheckJs({
paramName: msg,
paramType: JsTypes.String,
expectedType: JsTypes.String,
});
let output = msg;

if (optional.length > 0) {
output += optional.join(" ");
}

return output;
};

export { aFunction };
`

Not 1-2 line(s) of code?

The code given in the example is full code.

The exact type-checking code is:

`ts
typeCheck({ paramName: msg, expectedType: JsTypes.String });
`

And

`js
typeCheckJs({
paramName: msg,
paramType: JsTypes.String,
expectedType: JsTypes.String,
});
``

It is same for both TypeScript and JavaScript
