1) First step is downloading a virtual machine with Internet Explorer link = https://developer.microsoft.com/en-us/microsoft-edge/tools/vms/ Select your virtual machine in the drop down NOTE: I am going to choose IE on Win81 Then select the platform NOTE: VirtualBox and Vagrant are free but I have found VirtualBox is easier to get up and running If you would like to download virtual box here is a direct link https://download.virtualbox.org/virtualbox/6.0.8/VirtualBox-6.0.8-130520-OSX.dmg If you would like to download vagrant here is a link https://releases.hashicorp.com/vagrant/2.2.4/vagrant_2.2.4_x86_64.dmg With vagrant it is easier to manage with vagrant manager https://github.com/lanayotech/vagrant-manager/releases 2) Now that the IE VM is downloaded, install it and make sure you are able to connect to the internet 3) Next create an account on Ngrok https://dashboard.ngrok.com/ NOTE: This is the secret to connecting the VM to your local development (ie: localhost:3000) 4) Download and install Ngrok NOTE: It's easiest to download into your home directory 5) Now that we have Ngrok and IE VM installed start your local development My local developmen is running on http://localhost:8100 so to run ngrok I wil use the following ~/ngrok http 8100 -host-header="localhost:8100" NOTE: Ngrok will provide the forwarding url example: http://28214884.ngrok.io 6) In the IE VM past the forwarding url into IE address bar and you should now see localhost:8100 within IE on the VM
