Sometimes you want to interact with a local webserver with https support because of some browser APIs that are only available in an https environment.
You can easily create a self-signed TLS cert for development purposes with [`mkcert`](https://github.com/FiloSottile/mkcert).
```bash
brew install mkcert
mkcert -install # Install the local CA in the OS keychain
```
After installing `mkcert` and generating system-wide local CA cert, you can create a certificate for each project.
```bash
cd awesome-website
mkcert localhost # this will generate ./localhost.pem and ./localhost-key.pem
npm install -g serve
serve --ssl-cert ./localhost.pem --ssl-key ./localhost-key.pem
```
