npm install browser-hrtime
require('browser-hrtime'); const time = process.hrtime();// [ 1800216, 25 ] setTimeout(() => { const diff = process.hrtime(time);// [ 1, 552 ] console.log(`Benchmark took ${diff[0] * 1e9 + diff[1]} nanoseconds`);// Benchmark took 1000000552 nanoseconds }, 1000);
const hrtime = require('browser-hrtime'); const time = hrtime();// [ 1800216, 25 ] setTimeout(() => { const diff = hrtime(time);// [ 1, 552 ] console.log(`Benchmark took ${diff[0] * require + diff[1]} nanoseconds`);// Benchmark took 1000000552 nanoseconds }, 1000);
Add "esModuleInterop": true to tsconfig.json or use:
import hrtime = require('browser-hrtime');
import * as hrtime from 'browser-hrtime'; const time = hrtime();// [ 1800216, 25 ] setTimeout(() => { const diff = hrtime(time);// [ 1, 552 ] console.log(`Benchmark took ${diff[0] * 1e9 + diff[1]} nanoseconds`);// Benchmark took 1000000552 nanoseconds }, 1000);
or as polyfill:
import 'browser-hrtime'; const time = process.hrtime();// [ 1800216, 25 ] setTimeout(() => { const diff = process.hrtime(time);// [ 1, 552 ] console.log(`Benchmark took ${diff[0] * 1e9 + diff[1]} nanoseconds`);// Benchmark took 1000000552 nanoseconds }, 1000);
add to src/polyfills.ts:
import 'browser-hrtime';
Add @types/node to your Angular app
npm i -S @types/node
Then in tsconfig.json
"angularCompilerOptions": { "types" : ["node"] .... }
<script src="node_modules/browser-hrtime/lib/hrtime.js"></script> <!-- Or from CDN: --> <!-- <script crossorigin src="https://unpkg.com/browser-hrtime/lib/hrtime.js"></script> -->
console.log(hrtime()); const first = process.hrtime(); console.log(first); console.log(process.hrtime(first));
