So you're still stuck with errors? One of the most frustrating things about Go is dealing with errors. Error handling in Go is a topic that has been discussed for the last couple of years. Although there are some proposed changes to the language that will hopefully improve error handling, little progress has actually been made. What every programmer want is to get more stability and reliability. In this video I will go over some of the most sensible proposals that has the most traction and see how we can fix error handling in Go. Enjoy!

In today's video we learn about error handling in Go! In this tutorial we will learn how to handle errors, return errors, create custom error types, and some error handling best strategies in Go! We will learn the difference between other languages that use try/catch and throw for errors and exception versus the idiomatic way Go handles errors. So if you are just starting out and don't understand error handling in Go, then this is the video tutorial for you!

Go 1.13 introduced support for working with wrapped errors, in the form of three new functions and a new formatting directive. But those small changes have big ramifications for how you return errors from your code, and how you act on errors from the code you call. Jonathan's talk begins by defining what it means to wrap errors, and when you’d want to do so (and when not!). He'll then explain how the additions to the errors and fmt packages support wrapping. Jonathan will also address some features that didn't make it in, like stack traces and formatting. He will show how you can incorporate those features, and others like error codes, into your own error packages.
How to handle Error in Golang Error Handling in Golang is done through the build in interface type, error. Its Zero value is nil. So, if it returns nil, that means there were no errors in the program. Simple Example to understand Error Handling in Golang.

In this video I share with you the approach I like to take and the best practices I follow when implementing domain errors in Go/Golang using the Hexagonal Architecture and writing idiomatic code: * How to implement new errors * How to deal with errors * How to wrap errors * How to define concrete codes to determine where errors come from All of that using the new API introduced by Go 1.13: * errors.Is * errors.As * errors.Unwrap And the new verb added to the fmt package called %w. This is the first of a series where I will cover more things related working with errors and dealing with failures where I'm planning to cover: * Observability using OpenTelemetry * Observability using NewRelic * Resilience via Retries, Backoff algorithms and Circuit Breaking. * Example code: 🤍 * Blog post: 🤍 * Previous episode: "Building Microservices in Golang: REST APIs - Versioning Techniques" 🤍 * Playlist "Golang/Go Tools and Packages": 🤍 * Playlist "Building Microservices in Go/Golang": 🤍 * Playlist "Golang/Go Testing": 🤍 00:00 Start 00:10 Agenda 00:40 Errors in Go 1.13 04:07 Other resources 06:23 Demo: project structure 07:34 Demo: implementing errors 08:23 Demo: errors in domain package 09:19 Demo: errors in PostgreSQL repository package 10:01 Demo: errors in service package 10:17 Demo: errors in rest package 11:27 Demo: connecting everything using swagger-ui 13:13 Demo: recap 14:30 Parting words - Who am I: Hello👋🏼!

This presentation was recorded at GOTO Chicago 2018. #gotocon #gotochgo 🤍 Joe Armstrong - Principal Inventor of the Erlang Programming Language ABSTRACT Handling errors in programs is tricky. We want to write systems that work reasonable well even if there are errors in the code. This is possible, and the results have been used in production systems for many years. This talk outlines the do's and don'ts of error handling. Things you should do if you want to write fault tolerant code, and things you should not do. I will argue that making fault-tolerant and scalable systems is possible if you [...] Download slides and read the full abstract here: 🤍 🤍 🤍 🤍 #ErrorHandling #Erlang #FaultTolerance Looking for a unique learning experience?

About the talk: CockroachDB has seen a relatively large amount of bugs in 2018-2019 due to improper error handling, in turn stemming from Go’s “idioms” (community recommendations). Close inspection has revealed that previous Go best practices turn into outright bugs and code complexity when the code is distributed and error handling spans a network. The various problems have been identified in the CockroachDB RFC here. The talk will summarize the main findings and generalize them to other Go projects beyond CockroachDB, as well as present the general design directions behind the general-purpose ‘errors’ library aiming to become a drop-in replacement to Go’s standard errors package in distributed Go apps. About the speaker: Raphael 'kena' Poss (🤍kena42) graduated with a PhD in computer architecture. I work with compilers and, lately, databases. I am also a major contributor to CockroachDB, one of the largest Go codebases. I like to scrutinise the choices made by the implementers of the Go compiler. #gopherconEU

UPDATE: At 8:32 you should replace the generic string with err.message to send a dynamic error message to the client. Are you fed up writing try…catch in your Node.js application? In this video I’ll show you how to set up a global error handler in a Node.js application in a few easy steps. You will never have to write another try…catch statement again! This trick will save you from writing hundreds of lines of unnecessary code. The tutorial uses Express.js but this technique will work with any framework and an API. It’s simply a higher order function (HOF) that wraps around your function calls to catch errors. QUESTIONS Have a question about error handling in Node.js?

Serverless technologies introduced new ways to build highly scalable, resilient applications without managing infrastructure. When building serverless applications by using several managed services, how should you handle errors? Should you include a try/catch block in your code or let the service deal with errors? What if the function is invoked as a task in an AWS Step Functions state machine? Can AWS Lambda Destinations help? In this session, explore error handling across Lambda invocation models and discuss patterns for proper visibility and retry behavior. Leave this session with a better understanding of how to code and/or configure services to better deal with errors across different use cases.

Can We Panic Yet? Error Handling in Go Golang’s “one-size-fits-all” error handling is not a panacea. Alternatives provide good performance, and perhaps more surprisingly, are actually cheaper from a software engineering perspective. In this talk, Raphael dives into the Go calling convention and quantify experimentally the mandatory performance overhead of Go’s return value handling, as well as that of handling Go’s panics, a variant of exceptions found in other languages. There is a surprising inflection point with regard to performance between error returns and panic-based exceptions to signal errors, which challenges the programming idioms recommended by the Go team. In fact, we will see how panic-based exceptions can not only improve performance, but generally improve code quality and reduce software engineering costs. These insights will be illustrated through the software patterns found in a major open source project written in Go, CockroachDB. ✅ Follow Raphael Twitter: 🤍 LinkedIn: 🤍 GitHub: 🤍 ✅ Follow us on social media for the latest updates!

Webinar Description Most modern programming environments offers exception handling in some form, and SQL Server provides the popular TRY-CATCH concept. However, error handling in SQL Server is not as straight¬forward as one may wish, but it is marred with inconsistencies and surprises. This session starts off by displaying the some of the surprises you can encounter, both when you use TRY-CATCH and when you don’t. The session presents a recipe for writing CATCH block where focus is on keeping things simple and you will learn why it is not a good idea to make your error handling “fancy”, although it may seem to be a good idea in theory. The session also covers a few things to think of on client level.
