In this short article, we would like to show how to run Node.js application with ignoring/accepting unauthorized certificates (lets to create HTTPS connections with untrusted addresses).

Quick solution:

xxxxxxxxxx

• NODE_TLS_REJECT_UNAUTHORIZED=0 permits to create HTTPS connections with untrusted addresses - useful in development mode.

It is necessary to indicate the script was want to run. In our case, it will be devServer located in the scripts property.
