How to debug a Wails application (golang)

In the following you will find all the configs and script to fully debug your wails application (Both the frontend and the backend) in vs code while also having live reload.

What you need

• install delve if you haven't already
• python3.x

How it works

Since @ngtools/webpack doesn't support preprocess chain loader, see (here)[https://github.com/nippur72/ifdef-loader/issues/4].
We use process.env to pass the ifdef loader options and patch the compiler (webpack) to read the env and parse the files.
We use a prefix 'IFDEF_' to filter the environment variables.

This is more a fix than anything else for now. A better fix would have been a PR to enable webpack to use any preprocessor 
but I don't have the time right now.

BroadcastChannel Polyfill

BroadcastChannel is a new communication API proposed in the HTML Standard but not yet widely implemented. It allows messages to be sent to all other BroadcastChannel instances sharing the same channel name within the same browsing context and origin.

var bc = new BroadcastChannel('name');

bc.postMessage(payload);

The default format of keys was changed in OpenSSL 1.0. From OpenSSL 1.0 change log:

Make PKCS#8 the default write format for private keys, replacing the traditional format. This form is standardised, more secure and doesn't include an implicit MD5 dependency. [Steve Henson]

Good explanations of the difference between the two formats: https://tls.mbed.org/kb/cryptography/asn1-key-structures-in-der-and-pem
