![]() ![]() If you’d like more information on creating APIs, you might check out my previous tutorial titled, Create a Simple RESTful API with Node.js, or even my in-depth eBook and video course, Web Services for the JavaScript Developer. We’re going to build an incredibly simple RESTful API with Express Framework that uses our self-signed certificate. Developing an HTTPS Secured API with Express Framework With the certificate generated and in place on macOS, we can work towards using it in Node.js. When you close the window after making the change, you may be prompted to enter your password. If you are more comfortable choosing only what you need, go for it. Double click on the certificate entry to be brought to a new window with the certificate information.īecause this certificate is self-signed for localhost testing, it is easiest to choose the dropdown and select to always trust what the certificate has to offer. With the certificate added, we need to change the trust so that way it is actually used by our web browsers. You may be prompted to enter your computer password and if not, you will be prompted later. To do this, you’ll need to open your Keychain application. cert file in hand, the next step is to install it as a trusted authority on macOS. Installing the Certificate in the macOS Keychain ![]() cert file as both will be necessary when configuring the Node.js application. To make the certificate localhost compatible, it is important that you use localhost as the common name when prompted by the second command.ĭon’t lose the. The above commands are not specific towards generating a localhost certificate, but they are for a self-signed certificate. In the second command, we generate a certificate that expires after a a year. The first command will generate a private key to be used when creating your certificate in the second command. The above commands will do two different things. Openssl genrsa -out server.key 2048 openssl req -new -x509 -key server.key -out server.cert -days 365 If you’re on a Mac and you’ve already got your development tools installed like Xcode, you should already have the necessary command line tools to be successful.įrom the command line, execute the following: Creating a Self-Signed Certificateīefore we tell Node.js that we want to use a self-signed certificate for testing on localhost, we need to actually generate that certificate. While we’re not going to explore U2F hardware keys in this tutorial, we’re going to take a look at creating and installing a self-signed certificate for use in Node.js within macOS. ![]() The problem is that these services are for live domain names, not necessarily localhost. HTTPS is common, but I’d never actually set it up with Node.js because I had always been using services like Cloudflare that configure it for you. Things were going smooth until I realized that it is mandatory to be using HTTPS within your application, even when testing locally. I recently picked up a Yubico U2F hardware key and thought I’d try to create a web application that was protected with two-factor hardware-based authentication. ![]()
