Docker

Building an image

Note: don't forget to create a Dockerfile in the same directory. Next command build new php-obfuscator image from current directory:

docker build -t php-obfuscator .

How to verify? Next command should print info about new image:

Add line "browserslist": ["since 2017-06"] to your package.json file. Babel won't add polyfills for async/await, es6. So you don't need to install and add reneneratorRuntime (or babel-polyfill) to your bundle!

How to run puppeteer tests with your local Chrome browser

Find browser's executable path:
Go to chrome://version/ (inside Chrome browser) and find "Executable Path" variable ("/Applications/Google Chrome.app/Contents/MacOS/Google Chrome" in my case)
Modify your script:

const browser = await puppeteer.launch({
    executablePath: '/Applications/Google Chrome.app/Contents/MacOS/Google Chrome',
    args: ['--disable-blink-features=AutomationControlled'],
 headless: false,

du -shc * | sort -h - показывает сколько места занимает каждая директория

arr - array of objects
id - filter value

arr.filter((item, index, arr) => arr.findIndex(_item => _item.id === item.id) === index)

Пример, нужно дернуть какую-то стороннюю апиху https://my-awesome-api.haha CORS настроен таким образом что ты не можешь это сделать со стороннего домена, а доступа к серверу апихи нет (сторонеее апи же). То можно использовать прокси-сервер для этого. CORS реализованы в браузере только.

npx local-cors-proxy --proxyUrl https://my-awesome-api.haha

Это тулза выдаст примерно следующее:

	const express = require('express')
	const cors = require('cors')
	const bodyParser = require("body-parser")
	const app = express()

	const PORT = process.env.port \|\| 4000

	// to parse req.body for POST-requests
	app.use(bodyParser.urlencoded({extended: true}));
	app.use(bodyParser.json());

	const firebase = require('firebase');
	require('firebase/firestore');

	// firebase DB
	const firebaseConfig = {
	apiKey: '',
	authDomain: '',
	projectId: "",
	storageBucket: "",
	messagingSenderId: "",

	const loadIconAndConvertIconToBase64 = url => {
	return fetch(url)
	.then(response => response.blob())
	.then(blob => new Promise((resolve, reject) => {
	const reader = new FileReader()
	reader.onloadend = () => resolve(reader.result)
	reader.onerror = reject
	reader.readAsDataURL(blob)
	}));
	}

	async function getJSON(response) {
	if (response.status === 204) return '';
	return response.json();
	}
