Automatically add types to node.js TypeScript code using typewiz-core
yarn global add typewiz-node
or
npm install -g typewiz-node
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.
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.
