Let's Encrypt

Examples of getting certificates from Let's Encrypt working on Apache, NGINX and Node.js servers.

Obtain certificates

I chose to use the manual method, you have to make a file available to verify you own the domain. Follow the commands from running

git clone https://github.com/letsencrypt/letsencrypt
cd letsencrypt

In the default React Native app scaffolding you have to edit AppDelegate.m to change where it loads the code if you want to test on your device. I use the following snippet to detect if it's being compiled for Debug or Production and for the Simulator or a device. For Production it uses a copy of the code included in the bundle, for Debug on the simualtor it loads from a server on localhost and for Debug on a device it loads from a server on a given IP address.

NOTE: You need to edit YOUR-IP-HERE and change it to the IP to load the code from when in Debug mode on a device. You could use a service like ngrok to make this work from anywhere.

  NSURL *jsCodeLocation;

  // Loading JavaScript code
  #if DEBUG
    // For Debug build load from development server. Start the server from the repository root:
