typewiz-node

typewiz-node

Automatically add types to node.js TypeScript code using typewiz-core

Installation

yarn global add typewiz-node

or

npm install -g typewiz-node

Usage

typewiz-node <main.ts>

If you want to enable typewiz for your mocha test, simply add -r typewiz-node/dist/register to your mocha command-line, e.g.:

mocha -r typewiz-node/dist/register src/**/test.ts

This will run your unit tests, discover type information, and write it back to your source files.

Example

Given the following input file:

function greet(who) {
    return `Hello, ${who}`;
}

console.log(greet('Uri'));

Typewiz will run the program and then the code will be updated as following:

function greet(who: string) {
    return `Hello, ${who}`;
}

console.log(greet('Uri'));

Note the addition of the : string type for the who parameter in the first line.
