Using the rbt CLI

Bring your own certificate with rbt dev run​

By default rbt dev run backends use plain HTTP, not HTTPS. This makes for easier development, but due to web browser limitations the number of connections to the backend over HTTP will be limited - beyond 200 connections it is required to use HTTPS. To enable HTTPS you must provide your own TLS certificate when running rbt dev run.

Generating a Certificate with mkcert​

You can use mkcert to issue a certificate. Follow these steps:

  • Install mkcert: Refer to the instructions in the mkcert README for installation.
  • Install the root certificate: Run the following command: mkcert -install.
  • Issue a certificate: mkcert localhost.
note

Running mkcert <domain> will issue a certificate for the specified domain. For local development, it is recommended to include localhost in the certificate's Subject Alternative Names. If you use a custom domain, ensure it points to 127.0.0.1 in your /etc/hosts file for rbt dev run to work seamlessly.

Configuring rbt dev run with the Certificate​

Once the certificate is issued, configure rbt dev run with the following flags:

  • --tls-certificate=<path> - The path to the certificate file (e.g. localhost.pem).
  • --tls-key=<path> - The path to the key file (e.g. localhost-key.pem).
  • --tls-root-certificate=<path> - The path to the root certificate file (e.g. rootCA.pem). To locate the root certificate, use: mkcert -CAROOT.

Updating Reboot React Endpoint​

note

Make sure to update the RebootClientProvider's url to use HTTPS when using a custom certificate.

This setup ensures secure local development with custom certificates and enables compatibility with rbt dev run.
