[0:00]Hello, this is Chris from the Netlify team, and today I'm going to give you a quick intro to Netlify serverless functions. Netlify functions are built on AWS lambda, but you don't need an AWS account to use them. You just write your functions, deploy them to Netlify, and they just work. What this allows you to do is to add server side code to any project that you're building on Netlify. A common use case for Netlify functions is to protect API keys. For example, if you're building a site that uses a third-party API, you don't want to expose your API key directly in your front-end code. Instead, you can create a Netlify function that makes the request to the third-party API and then returns the data to your front-end. This way your API key is never exposed to the client. Another common use case is to handle form submissions. When a user submits a form on your site, you can use a Netlify function to process that submission, save it to a database, send an email, or trigger any other custom logic you need. Netlify functions are also great for more complex tasks like image processing, sending notifications, or integrating with other services. They provide a flexible way to extend the functionality of your site without having to manage a dedicated server. Now, let's take a look at how to create a simple Netlify function. All you need to do is create a functions directory in the root of your project. Inside that directory, you can create a JavaScript file for each function. For example, let's create a file called hello.js. Inside hello.js, we'll write a simple JavaScript function that returns a greeting. Here's what the code looks like.
[1:43]This function takes an event object as an argument, which contains information about the request. It then returns an object with a status code and a body. The body can be any string, but it's often JSON. To deploy this function, all you need to do is push your code to your Git repository, and Netlify will automatically deploy your function along with your site. Once deployed, your function will be accessible at a URL like yoursite.netlify.app/.netlify/functions/hello. You can then make a request to this URL from your front-end code to execute the function. And that's it. A quick intro to Netlify serverless functions. They're a powerful way to add server-side logic to your projects without the overhead of managing a server.
