Vanilla JS Login System Using A Custom API Full Series - #80
I do not use Bootstrap, jQuery, or any other frameworks. This method can be used on local browsers, web apps, and even on your server since it is all front-end code.
Next, we convert data from MySQL to JSON format using PHP, OOP, and PDO. This is a simple way to create information that can be read by an external application. In this tutorial, we create an application that makes data accessible on different platforms regardless of code. We create a REST or RESTful API that takes data from a server opens it to your applications. Converting the data to JSON is the first step to building your own API.
Finally, we tie it all together. Using JS Fetch, we send a username and password as JSON to our API, validate that against our database, then finally return with an error message or a single user account.
This project will teach you about the basics of JS fetch and how to encode and send JSON data using JS. It will also show you how to get that JSON data and interpret it in a way our API can understand and return the correct information or messages.
