Using json2ts to generate TypeScript interfaces from your JSON

This last recipe is more of a tip than a recipe; if you've got some JSON you developed using another programming language or by hand, you can easily create a TypeScript interface for objects to contain the JSON by using Timmy Kokke's json2ts website.

How to do it…

import module = require('module');
