Using Xdebug in Docker

Getting setup and running with Xdebug in a docker container these days is now fairly simple and is composed of two main steps:

Ensure you've got XDebug installed and enabled in your PHP docker image, for example:

# Installing Xdebug with PHP 7.3 images:
RUN pecl install xdebug \
  && docker-php-ext-enable xdebug

Go (Golang) GOOS and GOARCH

All of the following information is based on go version go1.17.1 darwin/amd64.

GOOS Values

GOOS	Out of the Box

`android`	✅

Common Options

-#, --progress-bar Make curl display a simple progress bar instead of the more informational standard meter.

-b, --cookie <name=data> Supply cookie with request. If no =, then specifies the cookie file to use (see -c).

-c, --cookie-jar <file name> File to save response cookies to.

Debug your PHP in Docker with Intellij/PHPStorm and Xdebug

For your local dev, create a Dockerfile that is based on your production image and simply install xdebug into it. Exemple:

FROM php:5

RUN yes | pecl install xdebug \
&amp;&amp; echo "zend_extension=$(find /usr/local/lib/php/extensions/ -name xdebug.so)" &gt; /usr/local/etc/php/conf.d/xdebug.ini \

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.
