If your Express app is using JavaScript, feel free to shift it to Azure Functions using JavaScript. The project represents a simple Node Express APIs app in TypeScript that is shifted to Azure Functions.īut what if you aren't using TypeScript? That's fine. What's in the sample project on GitHub that you'll learn about in this article? Great question! So why make this shift? Overall there is less to think about with serverless. What does this mean in a concrete example? Well, for this sample app the server.ts file effectively goes away.

Often there is very little code and some configuration. While Azure Functions don't make this go away entirely, there is less logic and less code to start Azure Functions. This sample project has a minimal amount of middleware, but you'd certainly want more in a production app with more concerns (ex: security) and features (ex: logging).

It would be nice to alleviate some of this effort and cost.Įxpress apps often have a long list of middleware and logic to start the server. Planning the Shift to Serverlessīefore shifting the app to serverless, let's think about why we might want to do this and what effort it might take to perform the shift.įirst, the Express app requires a server which you must configure and maintain. We'll walk through the code and the steps together, and at the end I share links to everything you need to get started and try this for yourself. While this article walks through the steps to shift your APIs from Express to Azure Functions, you can also follow along with the completed sample project on GitHub.

understand the differences between the approaches.

refactor existing Express APIs to Azure Functions.

Finally, we'll explore the results together. Then we'll walk through creating an Azure Functions app followed by refactoring the Express routes and data calls to the Azure Functions app. We'll start by exploring and running the Node and Express APIs in the sample project. Shifting from express to azure functions What You'll Learn

You'll learn how to shift your Node Express APIs to Serverless Functions in this article. Is it perfect? No, of course not! But this is a solid option if these factors affect you. Shifting to serverless alleviates the cost, the server upkeep, helps scale up and down easily, and reduces the surface area of the middleware required for a robust Express app.

I love Node and Express for creating APIs! However, these require a server and paying for that server in the cloud. Update: Try everything you see in this article in this hands-on tutorial But have you ever considered shifting this server based API model to a serverless one? Stick with me and this by the end of this article you'll see how to do it and have a working example to try for yourself. If you have Express APIs you are not alone.
