Making QR codes with cloud functions • tommorris.org

Tom makes an endpoint for generating QR codes so you don’t have to rely on the Google Charts API.

He also provides a good definition of “serverless”:

Now, serverless is a very silly buzzword dreamed up by someone from the consultant class who love coming up with terrible names, so I promise I won’t use it any further. Your code obviously run on a server. It just means it runs on a server someone else manages.

Amazon call it a ‘Lambda Function’. Google call it a ‘Cloud Function’. Microsoft Azure call it simply a ‘Function’. But none of those are very descriptive, because, well, anyone who writes any kind of programming language generally writes functions pretty much all the time in much the same way as anyone who writes English writes paragraphs, and we don’t call our blogging software “Cloud Paragraphs”. (Someone will now, I’m guessing.)

The Power of Serverless

Chris has set up a whole site dedicated to someone-else’s-server sites with links to resources and services (APIs), along with ideas of what you could build in this way.

Here’s one way to think about it: you can take your front-end skills and do things that typically only a back-end can do. You can write a JavaScript function that you run and receive a response from by hitting a URL. That’s sometimes also called Cloud Functions or Functions as a Service, which are perhaps better names, but just a part of the whole serverless thing.
