In the world of serverless applications, Webiny is becoming a popular way to adopt the serverless approach of building applications by providing handy tools that developers can build their apps upon. In this article, we will look into what Webiny is and try out the headless CMS as a data source for a Gatsby blog application. This article has been kindly supported by our dear friends at Webiny who help folks to architect, build and deploy solutions on top of serverless infrastructure. Thank you! In time past, developers reduced the challenges associated with managing content-dependent platforms through the use of Content Management Systems (CMS) which allowed web content to be created and displayed using existing design templates provided by the CMS service.
