Once you've made all the above changes to your JavaScript project, run your build tool and you should have your TypeScript project compiled into plain JavaScript that you can run in the browser. All you need to do is install the types for each of the libraries used in your project.įor example, for Jquery, install the definition: npm install list of all available TypeScript Type definitions can be seen here. So, we don't need to add types to these ourselves. TypeScript needs to know the types of all objects in these libraries in order to compile files.įortunately, TypeScript Type definition files for most JavaScript libraries are already available at DefinitelyTyped. Most JavaScript projects use third-party libraries like jQuery or Lodash.
