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:

Run single test

node <path-to-jest> -i <you-test-file> -c <jest-config> -t "<test-block-name>"

Change Iphone submit button text from "Go" to "Search"

You need create form and at least one input element. Required:

input with type="search"
define attribute "action" at form

<form action="">
	<input type="search" name="q" aria-label="Search" />

Fetch handle response

Variant 1

const requestOptions = {
    mode: 'cors',
    headers: {
      'Content-Type': 'application/json',
      'Access-Control-Allow-Origin': '*'
    }

Quick servers

Python

user@user-pc:~$ python3 -m http.server 8000
user@user-pc:~$ python -m SimpleHTTPServer 8000
