I have a simple module. Use for checking variable type.
index.js
'use strict';
var typeOf = function (variable) {
return ({}).toString.call(variable).match(/\s([a-zA-Z]+)/)[1].toLowerCase();
};
module.exports = typeOf;
index.d.ts
export default typeOf;
declare function typeOf(value:any):string;
Here how I use it.
import typeOf from 'lc-type-of';
typeOf(value);
But the code dosen't work as expect. The typeOf function came out undefined error. Do I miss something?
when you export node like with Javascript:
module.exports = something;
in Typescript import it like :
import * as something from "./something"
and in the definition
// Tell typescript about the signature of the function you want to export
declare const something: ()=> void ;
// tell typescript how to import it
declare module something {
// Module does Nothing , it simply tells about it's existence
}
// Export
export = something;
error TS2349: Cannot invoke an expression whose type lacks a call signature. Type 'typeof "E:/project/node_modules/lc-type-of/index"' has no compatible call signatures.
