海外TECH	DEV Community	Express.js Server Error Handling Explained	https://dev.to/code_black/expressjs-server-error-handling-explained-2e4d	Express js Server Error Handling ExplainedEffective error handling on the web server is a critical component of developing a resilient system  since when an error is handled effectively you are less likely to become irritated when anything goes wrong By supplying helpful information and precise error code you will be able to troubleshoot quickly Only operational errors will be addressed in this article Before we go into how to handle operational failures let s build a node js server using express js Express js is built on top of node js a powerful JavaScript engine that enables server side programming Table Of Contents Setting up Express Server Building Components for Efficiently Dealing With Errors Endpoint Creation Web Server Example ErrorsLet s dive in Setting up Express Server Creating the projectmkdir error handlingcd error handlingnpm initnpm i express nodemonUse mkdir to create a folder in the root directory and move cd to the folder that was created Create a package json that will keep record of all the dependencies that will be used for this article Install the following dependencies nodemon to listen for changes in the source file and restart the serverRunning the servercreate an app js file app js const app express const PORT app get req res gt res send Welcome to error handling in Express app listen PORT gt console log Server is running on port PORT In app js create an instance of expressCreate the server and listen to incoming HTTP request on port Define the root route that handles HTTP GET request name error handling version description main app js scripts start nodemon app js author license ISC dependencies express joi nodemon Add a start script in the package json file the start script will start the server using nodemon On postman run localhost Hurray we have our server running Building Components for Efficiently Dealing With Errors Error handler middleware Any code that runs between the request and the answer is referred to as middleware The error handler middleware in this scenario will be an abstraction of the many errors that will be handled in the server It accepts error request response and next parameters If the error that is passed is an instance of the custom AppError handleError function respond with the statusCode errorMessage and errorStatus If the error is not an instance of AppError the respond will be a errorCode and an internal server error message because the error that occurred wasn t taken into consideration middleware handlError js const AppError require utils AppError const handleError err req res next gt if err instanceof AppError return res status err statusCode json message err message status err status res status json message Internal Server Error status module exports handleError AppError Class A customized error called AppError extends the new Error base error class It accepts the message argument and the errorCode Super method runs the base error constructor with the message parameter utils AppError js class AppError extends Error constructor statusCode message super message this statusCode statusCode this status statusCode startsWith fail error module exports AppError TryCatch Abstraction An abstraction called tryCatch delivers a middleware with a try and catch block when it receives a controller as an argument The controller is called in the try block and If an error occurs the next parameter is called in the catch block with the specified error exports tryCatch controller gt async req res next gt try await controller req res next catch err next err Endpoint Creation Before we build a model endpoint that will be utilized to show how errors are effectively handled Let s add handleError middleware to the server s index file app js const express require express const handleError require middleware handleError const app express const PORT app get req res gt res send Welcome to error handling in Express error handler middlewareapp use handleError app listen PORT gt console log Server is running on port PORT handleError middleware will be used to handle errors that occurs during a HTTP process Creating an Example Express Routercreate a user endpoint that returns an array of users This endpoint will be used to experiment several operational error that can be handled in a HTTP process routes user route js const express require express const tryCatch require utils tryCatch const getUsers require service users service const router express Router const userController tryCatch async req res next gt const users await getUsers res status json users router get user userController module exports router Web Server Example Errors Bad Request Error often known as When the web server cannot handle the request given by the web client a error is one form of HTTP response status that appears This kind of error is likely caused by the web client There are several things that might result in a error When the endpoint URL contains a mistakeWhen the web client gives the web server inaccurate or incomplete information A browser or internet connection issue for the usercode exampleWe can handle an invalid endpoint error in the app js file which is an example of a bad request error app js app get req res gt throw new AppError Invalid endpoint The asterisk character in Express Router can be used to match any number of characters in a route The asterisk route for example will be triggered when the specified URL does not match any of the existing routes In that instance the web server returns a error code Unauthorized Error often known as When a web client communicates with a web server without the necessary rights the web server responds with a error indicating that the user is not authorized to do the intended activity code exampleTo demonstrate the error let s build a user authentication middleware that checks to see if the user is authorized before completing the user request const AppError require utils AppError const authenticated req res next gt const isAuthenticated req headers authorization if isAuthenticated throw new AppError unauthorized request next module exports authenticated The authorized middleware will then be used in the user route routes user route js router get user authenticated userController If you query the user endpoint in Postman without authorization you will receive a error as seen in the picture below Not Found Error often known as A HTTP response status occurs when the web client can interact with the web server but the web server is unable to locate the requested resource Consider the following scenario you attempt to fetch your t shirt from your closet and you can t find it but you can go into your closet I hope this was helpful XD code exampleAssume there are no users on the server at the moment When we request the users the server returns a error The modifications may be done on the user controller const userController tryCatch async req res next gt const users undefined if users throw new AppError No users found res status json users Run the user endpoint in your postman Internal Server error often known as A response status indicates a web server issue and has nothing to do with the web client The following factors may contribute to the occurrence of a error When a problem arises with the web server hosting providerThe reason for a failed database connectionA programming error occurred in the web server code ConclusionFinally it is critical to always have a correct error handling structure on your web server in order to maximize the possibilities of troubleshooting specific operational errors that may occur when working on the web server I recommend you read this to learn more about how to handle errors efficiently in an express server Remember that your education does
