Create Your First Netlify Serverless Function!

Netlify lets you deploy serverless Lambda functions without an AWS account, and with function management handled directly within Netlify. Your serverless functions are version-controlled, built, and deployed along with the rest of your Netlify site, and we will automatically handle service discovery through our built-in API gateway. This eliminates overhead and brings the power of Deploy Previews and rollbacks to your serverless functions.

Server-less functions are essentially server-side functions that are hosted on a third-party service. They are great as they essentially mean we can run them on someone else’s server! All with the benefit of writing them in our own projects where the frontend code lives.

We are going to build our first Netlify Serverless Function with 3 easy steps:

Step 1: Installing the Netlify command line interface
Step 2: File setup: so creating a directory to store your functions and writing a configuration file
Step 3: Learning the syntax

If you would like to use Netlify Functions in a real working example, please visit my Tik Tok Clone Video, in which we use them along with DataStax.

How To Get Page Views From Google Analytics via a Netlify Serverless function

After getting my blog up and running I recently decided to add Google Analytics to it, to understand what content people were most interested in. At first this was amazing as I could see which blog posts were getting the most traction, but after a while it became a bit of a pain to log into

my Google Analytics dashboard when all I wanted was to quickly see the

page view count of a blog post.

Wouldn’t it be easier to just go to my site and see the page view count displayed on each blog post? It most certainly would, and so that’s what I set out to build. Since Google Analytics has a powerful API, all I really needed to do was call that API and retrieve my information, but ideally I wouldn’t want to be making that call directly from this blog as that would mean exposing my API key and any other sensitive information to anyone who knows hows how to press F12.

TL;DR Here is the GitHub repository for the serverless function that I wrote for retrieving Google Analytics page views.

Since this blog is setup to be completely free (aside from the domain name), leveraging Netlify for the hosting, Cloudinary for images and Ghost

for the content management system, I definitely wouldn’t want to pay

for running a back-end (especially one that was simply fetching stats

from Google Analytics). And that’s where Netlify functions come in.

Netlify has a very generous free plan that allows 125k function

executions and 100 hours execution time, a quota that this blog would

never reach within 1 month, and this seemed like a perfect fit for what I

needed.

Overcoming Common Serverless Challenges with Mainframe CICS Programs

By this point most enterprises, including those running on legacy infrastructures, are familiar with the benefits of serverless computing:

  • Greater scalability
  • Faster development
  • More efficient deployment
  • Lower cost

The benefits of agility and cost reduction are especially relevant in the current macroeconomic environment when customer behavior is changing, end-user needs are difficult to predict, and development teams are under pressure to do more with less.

So serverless is a no-brainer, right?

Not exactly. Serverless might be relatively painless for a new generation of cloud-native software companies that grew up in a world of APIs and microservices, but it creates headaches for the many organizations that still rely heavily on legacy infrastructure.

In particular, enterprises running mainframe CICS programs are likely to encounter frustrating stumbling blocks on the path to launching Functions as a Service (FaaS). This population includes global enterprises that depend on CICS applications to effectively manage high-volume transactional processing requirements – particularly in the banking, financial services, and insurance industries.

These organizations stand to achieve time and cost savings through a modern approach to managing legacy infrastructure, as opposed to launching serverless applications on a brittle foundation. Here are three of the biggest obstacles they face and how to overcome them.

Challenge #1

Middleware that introduces complexity, technical debt, and latency. Many organizations looking to integrate CICS applications into a microservices or serverless architecture rely on middleware (e.g., an ESB or SOA) to access data from the underlying applications. This strategy introduces significant runtime performance challenges and creates what one bank’s chief architect referred to as a “lasagna architecture,” making DevOps impossible.

How to Build and Deploy Serverless Functions to Netlify

Introduction

It is a good software engineering practice to separate portions of your code function to work independently of other parts. Since your codes are made up of functions basically, serverless functions allow you to deploy those functions without the complexity of managing a server to run them.

In this tutorial, we will be learning what serverless functions are, how to write them, and how to deploy them on Netlify in minutes. We will also touch up on other uses of serverless functions.

What are Serverless Functions?

A serverless function is a function hosted on a cloud infrastructure and performs a single purpose. It is very similar to every other function you write as long as it has its own dependencies and can run on its own. It is serverless because it takes off the stress of server maintenance and scaling the function from you.

Netlify has made it very easy to write any backend task and deploy it independently or alongside your project in simple steps. Your functions can also be deployed by a simple git push command if linked with your GitHub repository. These functions are called Netlify Functions.

Serverless functions work just like your API endpoint

Let’s Build our Serverless Function

Create a project folder

Create an empty folder either manually or by running mkdir custom-netlify-functions. Use any name you feel like. Here I’m using ‘custom-netlify-functions’.

Setup CI/CD with GitHub

Initialize repo with GitHub

  • Change to the folder cd custom-netlify-functions
  • Create a readme.md file touch readme.md
  • Run git init to initialize folder with Git repository
  • Run git add . && git commit -m "initial commit" to add the file and commit changes.
  • Go to github.com/new, create a new repo — preferably with same name
  • Link the local repository with your remote repo like so: git remote add origin git@github.com:YourGithubName/your-repo-slug.git
  • Run git push -u origin master to push your files

Install Netlify CLI

We will be using the Netlify CLI as it makes it super easy to get our project up and running Run npm install -g netlify-cli

Initialize Netlify in folder

If you don’t have a netlify account, create one now

While inside the folder, run netlify init to initialize the folder with netlify.

The prompt will ask you “What would you like to do?”, select “Create and configure a new site”. This option creates a new site on your netlify account.

If you are already authenticated, it will ask you to select your team (Netlify Account). If you aren’t authenticated on netlify.com yet, it will open a browser and request that you enter your login credentials.

The next prompt will ask your Site name and if you’ll like to authenticate with Github. For site name, retain the same name as ‘custom-netlify-functions’ and authenticate with Github

This step connects your Netlify account and repo with the same one you just created on GitHub.

Next prompts. For “Your build command”, simply press Enter key. For Directory to deploy to, press Enter key too to use “.” (the current directory).
