Setting up localhost SSL Cert

Create a file server.csr.cnf

openssl = genrsa
[req]
default_bits = 2048
prompt = no
default_md = sha256
distinguished_name = dn

[dn]
C=US
ST=RandomState
L=RandomCity
O=RandomOrganization
OU=RandomOrganizationUnit
emailAddress=hello@example.com
CN = localhost

Create a file v3.ext

authorityKeyIdentifier=keyid,issuer
basicConstraints=CA:FALSE
keyUsage = digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment
subjectAltName = @alt_names

[alt_names]
DNS.1 = localhost
IP.1 = 192.168.1.70

run the following

openssl genrsa -des3 -out rootCA.key 2048
openssl req -x509 -new -nodes -key rootCA.key -sha256 -days 1024 -out rootCA.pem
openssl req -new -sha256 -nodes -out server.csr -newkey rsa:2048 -keyout server.key -config <( cat server.csr.cnf )
openssl x509 -req -in server.csr -CA rootCA.pem -CAkey rootCA.key -CAcreateserial -out server.crt -days 500 -sha256 -extfile v3.ext

Angular

Just add the certs in

        "serve": {
          "builder": "@angular-devkit/build-angular:dev-server",
          "options": {
            "browserTarget": "bibbleWeb:build",
            "ssl": true,
            "sslKey": "../not_saying_relative_to_project/server.key",
            "sslCert": "../not_saying_relative_to_project/server.crt"
          },

And import it in Chrome

Import the rootCA.pem into chrome under the authorities page
