Network Error Handling

Introduction

A powerful error handling to manage network axios response errors.

Installation

npm install network-error-handling

yarn add network-error-handling

pnpm install network-error-handling

Usage

Network error handling

1. Import

import { networkErrorHandling } from "network-error-handling";

2. Call the function, example:

IMPORTANT: The error parameter is the AxiosError object from the axios response.

networkErrorHandling(error)
  .addError(
    409,
    "User already exists",
    "The user already exists, please try again with another email.",
    () => console.log("Error while creating user")
  )
  .handle();

Using toast

If you plan to display a toast of error, you will need to have a function to handle the toast, example using Shadcn UI toast component

import { toast } from "shadcn-components-folder-location/use-toast";

export const handleErrorToast = (title: string, description: string) =>
  toast({ title, description, variant: "error" });

After this, you can use the withToast method to handle the toast, example:

networkErrorHandling(error)
  .addError(
    400,
    "Invalid form data",
    "The form data is invalid, please check the fields."
  )
  .addError(
    409,
    "User already exists",
    "The user already exists, please try again with another email."
  )
  .withToast(handleErrorToast)
  .handle();

Ooh, you can also use a callback function when using a toast!

networkErrorHandling(error)
  .addError(
    409,
    "User already exists",
    "The user already exists, please try again with another email.",
    () => console.log("Error while creating user")
  )
  .withToast(handleErrorToast)
  .handle();

Status Codes

This package provides a list of status codes that you can use to handle the errors, example:

import { StatusCode } from "network-error-handling";

networkErrorHandling(error)
  .addError(
    StatusCode.CONFLICT,
    "User already exists",
    "The user already exists, please try again with another email."
  )
  .handle();

Api References

networkErrorHandling(error: AxiosError)

• error: The AxiosError object from the axios response.

addError(statusCode: number, title: string, description: string, callback?: () => void)

• statusCode: The status code to handle the error.
• title: The title of the error.
• description: The description of the error.
• callback: Optional callback function to execute when the error is handled.

CAUTION: For now, the callback parameter is not async aware, so you can't use async functions inside the callback.

Observation: You should handle the toast system by yourself in your project.

handle()
