node.js - How to use existing javascript files in typescript files? -

i have existing project in nodejs + express in javascript. working on es5.

now added typescript in same project , want new development in typescript. facing issue in accessing existing javascript files.

i found can create definition file xx.d.ts (not sure if correct approach) of each existing javascript file , use in typescript files.

for example have javscript file

myfile.js

function myclass(){ //some functions here associated variable }  exports.mydata = new myclass();

now want use in new ts file

so did in ts file access is

declare function require(path: string): any;  var auth = require('./myfile').mydata;

i not sure if right approach. secondly tried myfile.d.ts file well.

i defined file in following way

declare module './myfile' {   export var mydata: }

but gives error of relative path - ts2436 ambient module declaration cannot specify relative module path

please let me know if has idea resolve problem or suggest if okay go first approach.
