The term \"serverless\" will surely pique your curiosity when you first hear it. You may wonder \"How do I run code on the Internet without a server?\"<\/p>\n
What this really means is that you, as a developer<\/a>, don't have to worry about the servers your code is running on. Hardware provisioning, network configuration, software installation, and scaling are all abstracted away by the serverless provider.<\/p>\n So, in this post, we are going to guide you through the step-by-step process of a creating serverless application using Netfly<\/a> and JavaScript<\/a>. Let\u2019s take a look.<\/p>\n From a development standpoint, a serverless function is a package of code that you upload to a serverless provider (like AWS<\/a> or Google<\/a>). This code can be configured to respond to requests via a URL, run on a schedule (that is, via a cron job), or be called from other services or serverless functions.<\/p>\n Serverless functionality is ideal for adding some server functionality to front-end applications without the complexity and expense of running a full server. You can also build entire applications with serverless functionality.<\/p>\n When combined with other cloud services that provide file storage, database systems, and authentication, you can create large, reliable and scalable applications without the need to dedicate a single server.<\/p>\n To get a more practical understanding of working with serverless features, let's look at a real-world example. We will create a static page with a newsletter<\/a> sign up form that uses a serverless function to store the user's name and email address in a Google spreadsheet.<\/p>\n Serverless functions can be written in different languages depending on the vendor, but we are going to use JavaScript since Netlify supports Node.js functions. Before starting, please make sure that have the latest Node \/ npm<\/a> installed on your local machine.<\/p>\n What are serverless applications<\/h2>\n
