Component definition is missing display name

Often, a hook is going to need a value out of context. The useContext hook is really good for this, but it will often require a Provider to be wrapped around the component using the hook. We can use the wrapper option for renderHook to do just that. Let's change the useCounter example from the Basic Hooks section to get a step value from context and build a CounterStepProvider that allows us to set the value:. In our test, we simply use CounterStepProvider as the wrapper when rendering the hook:. The wrapper option will accept any React component, but it must render children in order for the test component to render and the hook to execute. Sometimes we need to test a hook with different context values. By using the initialProps option and the new props of rerender method, we can easily do this:. Note the initialProps and the new props of rerender are also accessed by the callback function of the renderHook which the wrapper is provided to. It can be very tempting to try to inline the wrapper variable into the renderHook line, and there is nothing technically wrong with doing that, but if you are using eslint and eslint-plugin-react , you will see a linting error that says:. If you feel strongly about not having a separate wrapper variable, you can disable the error for the test file by adding a special comment to the top of the file:. Similar techniques can be used to disable the error for just the specific line, or for the whole project, but please take the time to understand the impact that disabling linting rules will have on you, your team, and your project.

Component definition is missing display name

This error occurs when you define a component without providing a display name. In this blog post, we will explore the reasons behind this error and discuss multiple solutions to fix it. The display name of a component is used for debugging purposes and is typically shown in error messages or React DevTools. It helps developers identify which component is causing an issue. When the display name is missing, React throws an error to alert you about the missing information. The simplest solution is to assign a display name to your component. This can be done by setting the displayName property on the component. By setting the displayName property, you provide a human-readable name for your component, which will be used in error messages and React DevTools.
