![]() ![]() Lines 4–9: We define the markup of the component that renders a div element containing a p (paragraph) element and an img (image) element. For example, if the title prop contains the string 'Project 1', it will be returned as the string 'project-1'. It replaces the white spaces with dashes, making the title prop lowercase, and finally stores it in a constant imageName. Line 2: We perform string operation on the title prop. Line 1: We define a functional React component that accepts a title prop. Code example 1Ī common example of a white screen of death (WSOD) is when we try to access a certain property of an object which is undefined or null.Ĭonsider the following code snippet, and let’s dissect it line by line: We can also try using the React developer tools to inspect the component tree and identify issues with the component hierarchy. If WSOD is still there after checking for these potential issues, it may be helpful to use the browser’s developer console to try to identify the cause. Make sure to optimize your code and use tools like the React profiler to identify and fix any potential memory leaks. Memory leaks: If the application uses too much memory, it can crash. Make sure to check the code for any infinite loops. Infinite loops: An infinite loop in the code can cause the application to hang and appear to be a WSOD. Make sure to add try-catch blocks around code that could throw exceptions. Unhandled exceptions: If an exception is thrown in the code and not caught, it can cause the application to crash. Make sure to handle failed network requests gracefully by displaying an error message or a fallback UI. Make sure to check the code for any syntax errors.įailed network requests: If the application makes network requests to an API and those requests fail, it could cause the application to crash. Syntax errors: Syntax errors can cause the JSX elements in the application to fail to render. There are a few potential causes for this issue: ![]() The white screen of death (WSOD) in React refers to a situation where our React application appears to have crashed and only displays a blank white screen. ![]()
