Express error handling
In this lesson we will talk about error and exceptions in Node as well as in Express.
We will talk about sync errors as well as asynchronous errors.
We will demonstrate exceptions in async types like Promises, EventEmitter and Error first callback and we will learn how to deal with exceptions with those async patterns.
While covering how to deal with exceptions on Promises we will also demonstrate handling those exceptions on promises using the async-await.
We will show what happens on your Express application when you are not catching exceptions and we will also demonstrate best practices and using error middlewares in Express.
We will learn how to run our node server using process manager - pm2.
We will demonstrate using winston to log our exceptions.
