#10 Serving a web pageNovember 03, 2022
Let's set up the serving of our app's frontend. First, let's change the domain name of our server from
api.jurajmajerik.com to a more fitting
app.jurajmajerik.com. At this point, it's okay to serve both the frontend and the APIs from the same server. We might separate them out later.
To start, in the GoDaddy dashboard, we need to add a new A record with the name
app and point it to our server's IPv4 address.
We also need to generate a new SSL certificate, as any certificate pertains to a specific domain name. Because of this, if you try to access a domain at HTTPS with a non-matching certificate, you'll get a warning.
To solve this, we need to follow the steps described in the earlier HTTPS article, substituting
app. We can then update the
http.ListenAndServeTLS() method with the location of the newly generated certificate and the key.
Next, let's set up a
static folder in our
server directory. Here we can place an
index.html file with a simple "Hello world" message. In the future, we will serve any frontend files such as .css, .js, or any assets from this folder.
The code to serve frontend files is a simple one-liner added to the main function. At the
/ path, let's serve all of the files in the
Let's first run
main.go locally and check if the file is being served at
localhost:8080. Then, let's deploy it to the production server and start the server script there.
Our app frontend is now being served at https://app.jurajmajerik.com!
