Elixir Error Management: A Manual For Efficiently Managing Errors And Exceptions In Elixir Programmes

If you are not yet aware of the Elixir programming language, then now is the time to do so. Elixir has turned out to be a highly reliable programming language in recent times. It comes with a wide range of tools using which you can manage exceptions and errors in your program in a really effective way. 

 

Being a programmer, you must already be aware of the fact that errors and exceptions are an inevitable part of the development process which is why it is important that you remain well aware of the different ways in which you can manage errors and exceptions so that the entire coding process can take place in a highly effective manner. 

 

So, in order to help you out on your programming journey, we are here for you. We are going to provide you with a few tips and tricks that will allow you to manage exceptions and errors in your program in a highly effective and efficient manner. Let us have a look at what we have got in store for you:

 

Make use of pattern matching:

 

In Elixir, pattern matching can be used to handle errors and exceptions. By making use of pattern matching, you can match the expected value of a function call against the particular pattern. This can be a really great way of writing code. You will also not have to spend hours troubleshooting a particular error.

 

Use exceptions only when it is mandatory: 

 

You can use exceptions anywhere in your program using the raise function. However, it is recommended that you raise exceptions only when it is absolutely necessary. Otherwise, it is going to cause hindrance to your overall program structure.

 

Make use of the try catch block:

 

Try catch blocks are an effective way of handling exceptions and errors. Try catch blocks will allow you to catch unhandled exceptions that are raised by a function call. This is another great way of writing your code. It can also add a modular structure to your code.

 

Define custom exceptions:

 

Elixir allows us to include custom exceptions in our program including the defexception macro. You can also raise custom exceptions using the raise function. These exceptions can be caught by the try catch blocks.

 

Use supervisors to manage errors:

 

Supervisors are a really powerful tool of Elixir. This allows us to manage errors in a fault-tolerant way. You can use supervisors for starting, stopping, and restarting different processes in the Elixir application. As soon as a process fails, the supervisor can start the process or terminate it and launch a new process.

 

Use logger to log errors:

 

You can make use of the logger module to log errors and exceptions. This can be a really great way of logging different kinds of messages. It is also a really effective way of handling errors and exceptions in your program.
