如何在 React JS 和 webpack 中使用 moment.js 格式化时间

Question

I am using the moment JS to format dates in my React app which is NOT setup using create-react-app . I want to format the timestamp to a readable format like below:

1. If the timestamp supplied is for today it should show only show the time. eg: 2:00 pm .
2. If the timestamp supplied is for yesterday it should show yesterday without time. eg: Yesterday .
3. If the timestamp supplied is anytime before yesterday it should show the exact date without time. eg: 24 Feb, 2019 .

Code I have so far: webpack.config.js:-

    const MomentLocalesPlugin = require('moment-locales-webpack-plugin');
....
plugins: [
     new MomentLocalesPlugin({
         localesToKeep: ['es-us', 'hi']
     })
]

App.js

import React, { useEffect } from 'react';
import moment from 'moment';

const App = () => {
    const timestamp = '1571744305';
    return (
        <Router>
            <div>
               {moment(timestamp).calendar()}//08/21/2019
            </div>
    );
};

export default App;

Using moment.js, you can do like this

 let now = moment.duration().humanize(); let oneMin = moment.duration(1, "minutes").humanize(); // a minute let twoMin = moment.duration(2, "minutes").humanize(); // 2 minutes let hours = moment.duration(24, "hours").humanize(); // a 24 hours let days = moment.duration(24, "days").humanize(); // a 24 days let weeks = moment.duration(2, "weeks").humanize(); // a weeks let months = moment.duration(5, "months").humanize(); // a months let years = moment.duration(7, "years").humanize(); // a years console.log(now); console.log(oneMin); console.log(twoMin); console.log(hours); console.log(days); console.log(weeks); console.log(months); console.log(years);
