Typeify

Introduction

Typeify is a JS-to-TS (JavaScript to TypeScript) converter that converts your messy and bland JavaScript file into a nice, clean and type safety TypeScript file.

Documentations on how to use Typeify!

Install

First let's install it from npm:

npm install -g @starlo/typeify

Create a .js file

Second let's create a .js file as an example:

// example.js

var myVar = "ok"

if(!myVar) {
    console.log("not ok")
} else {
    console.log(myVar)
}

Now based on your opinion this might be messy or not clean so let's use Typeify!

Note(Seriously): You need to make the node_modules set to global in the system environment variables in order to make this work.

Type this command:

typeify example.js

or if you want to refer to a directory you can run:

typeify test/example.js

And the result should look like this:

// example.ts

let myVar: string = "ok";

if (!myVar) {
    console.log("not ok");
} else {
    console.log(myVar);
}

What Typeify does?

1. Converts .js files to .ts files
2. Adds basic type annotations
3. Fixes some common JavaScript issues (like using var)
4. Keeps your original .js file as a backup

Limitations

Typeify is a learning project and may not handle all JavaScript constructs perfectly. It's best used on simple JavaScript files and as a learning tool for TypeScript conversion.
