How to use TypeScript with Loopback

Question

I use Strongloop's Loopback as a REST framework and ORM. I want to use TypeScript for my business logic. However, Loopback requires some form of JavaScript to support their framework. For example:

module.exports = function(Person){ Person.greet = function(msg, cb) { cb(null, 'Greetings... ' + msg); } Person.remoteMethod( 'greet', { accepts: {arg: 'msg', type: 'string'}, returns: {arg: 'greeting', type: 'string'} } ); }; 

What is TypeScript code that will generate the above JavaScript code?

What is TypeScript code that will generate the above JavaScript code?

You can simply use this code as it is (JavaScript TypeScript). If you're curious about module.export , you can use the TypeScript flag --module commonjs to get it in a Typeaware type like this:

 function personMixin(Person){ Person.greet = function(msg, cb) { cb(null, 'Greetings... ' + msg); } Person.remoteMethod( 'greet', { accepts: {arg: 'msg', type: 'string'}, returns: {arg: 'greeting', type: 'string'} } ); }; export = personMixin; // NOTE!
