Use Angular CLI to serve https locally

Developing an angular application with HTTPS is useful, this is a guide outlining how to do it in a Linux environment.



Initialize an angular application by running ng new https-dev in your terminal. Once the application is generated, change directory into it and create a folder called ssl . This will contain the certificates needed.


Optionally you can edit .gitignore to ignore this folder, preventing it from being committed.

Using mkcert

There are instructions on the page to guide you through installing mkcert regardless of your OS. With mkcert installed, run mkcert -install to generate a local Certificate Authority (CA) and restart your browser to make sure it registers the newly generated CA.


Head to preferences and type in certificates in the search bar. Click on View Certificates and head to Authorities and locate mkcert development CA.



Head to settings and type in certificates in the search bar. Scroll down to Manage certificates and head to Authorities and locate org-mkcert development CA.


Generating certificates

At the root of your project, run the following command:

$ mkcert -cert-file <folder/filename.pem> -key-file <folder/filename.pem> <space delimeted domain>
$ mkcert -cert-file ssl/local-cert.pem -key-file ssl/local-key.pem localhost ::1 

Created a new certificate valid for the following names 📜
 - "localhost"
 - ""
 - ""
 - "localhost"
 - ""
 - "::1"

The certificate is at "./ssl/local-cert.pem" and the key at ".ssl/local-key.pem"
Enter fullscreen mode Exit fullscreen mode


Development with https

To use the certificate we generated, use the following:

$ ng serve --ssl <boolean> --ssl-cert <path-to-cert> --ssl-key <path-to-key>
$ ng serve --ssl true --ssl-cert ./ssl/local-cert.pem --ssl-key ./ssl/local-key.pem
Enter fullscreen mode Exit fullscreen mode

After the application is being served, check your address bar for the padlock. Indicating that localhost has https
