Pure ESM package

The package that linked you here is now pure ESM. It cannot be require()'d from CommonJS.

This means you have the following choices:

1. Use ESM yourself. (preferred)
   Use import foo from 'foo' instead of const foo = require('foo') to import the package. You also need to put "type": "module" in your package.json and more. Follow the below guide.
2. If the package is used in an async context, you could use await import(…) from CommonJS instead of require(…).
3. Stay on the existing version of the package until you can move to ESM.

var express = require('express')
var session = require('express-session')
var app = express()
var r = require('request')

// By default cookies are disabled, switch it on
var request = r.defaults( { jar:true } )

app.use(session({ secret: 'keyboard cat',saveUninitialized : false, resave : false, cookie: { maxAge: 60000 }}))

How to produce a reliable ant-design CSS with all rules prefixed ("namespaced")

I wrote this to add a prefix to all antd style rules (or any other external CSS files). It is far from perfect, but works surprisingly well at least for my needs ;-)

Thanks to @dbtedman for making this possible with his fine PostCSS postcss-prefixwrap plugin.

Prerequisites:

1. make sure Gulp is installed (yarn global add gulp-cli, the required gulp package is included in package.json)
2. adapt variables at top of gulpfile.js to your needs

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent
