execution-time-decorators

Measure of typescript method execution time

Adding to your project

In Node.js

Call require to get the instance:

const { sync_timer, async_timer } = require('execution-time-decorators');

Or in ES6 and TS:

import { sync_timer, async_timer, sync_hrtimer, async_hrtimer } from 'execution-time-decorators';

Usage

class ExampleTimers {

    @sync_timer
    public readSync(filepath: string) {
        return fs.readFileSync(filepath);
    }

    @async_timer
    public async readAsync(filepath: string) {
        return fs.promises.readFile(filepath);
    }

    @sync_hrtimer
    public static readSync(filepath: string) {
        fs.readFileSync(filepath);
    }

    @async_hrtimer
    public static async readAsync(filepath: string) {
        return fs.promises.readFile(filepath);
    }
