--- title: Securing Local Dev Server date: 2020-02-07 00:00:00 +0900 --- 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 ```
