ionic 3 / node.js - Self signed certificate in certificate chain (how to disable strict-ssl?)

Question

I cannot create a ionic project with ionic start because of following error:

Error: self signed certificate in certificate chain
    at TLSSocket.<anonymous> (_tls_wrap.js:1103:38)
    at emitNone (events.js:106:13)
    at TLSSocket.emit (events.js:208:7)
    at TLSSocket._finishInit (_tls_wrap.js:637:8)
    at TLSWrap.ssl.onhandshakedone (_tls_wrap.js:467:38)

on cmd: ionic start myApp tabs

Because our proxy sends a self-signed signature for all sites. (FortiGate of FortiNet)

In npm I set strict-ssl to false and works fine. But ionic loads the content over a node application, right?

How to setup node to ignore self signed certificates for all node applications or how to disable it for ionic?

Answer 1

I resolved my problem using:

set NODE_TLS_REJECT_UNAUTHORIZED=0

Answer 2

Setting set NODE_TLS_REJECT_UNAUTHORIZED=0 comes at a great risk to the security of your application. I would recommend avoiding this "work around" for production software. I recommend reading this before disabling.

I'm still trying to fix my own issue and will update if I come up with a safer solution.
