"TypeError: process.hrtime is not a function" about perfy HOT 4 CLOSED

I tried in server code

TypeError: perfy.start is not a function

from perfy.

I don't know how you transpile your code but perfy is a ES5 package (uses module.export). So it's important how you bundle your project if you're using import.

See this test using babel. This runs the following command to transpile:
npx babel index.js --out-file index-compiled.js --sourceType module --presets=@babel/preset-env

And below works as expected:

import perfy from 'perfy';            // works
// import * as perfy from 'perfy';    // also works
// const perfy = require('perfy');    // also works

perfy.start('test1');
setTimeout(() => {
    const result = perfy.end('test1');
    console.log(result);
}, 1000);

By the way, title of this issue is TypeError: process.hrtime is not a function.
Are you trying to use perfy in a browser environment? If so you can't. perfy is a lib for Node.js. It uses process object which is only available in Node.js (i.e. server side).
