I want to know if there is a way to create a kind of middleware in React?
What i want is to have an alert component show if there is a failing result for an http request.
Right now, i am making http request on login,registration,etc and i am importing my alert component in every page and setting the Alert component props like type, message, visibility everywhere i need the component, but i think maybe there is a better way of doing this.
Here is my code:
...imports
export const RegisterPage = () => {
const [alertConfig, setAlertConfig] = useState({
type: "",
message: "",
show: false,
});
...code
const onSubmitHandler = async (e) => {
e.preventDefault();
if (!isFormValid()) return;
const formData = new FormData();
formData.append("password", formValues.password);
if (formValues.provider.startsWith("8")) {
formData.append("contact", formValues.provider);
} else {
formData.append("email", formValues.provider);
}
setIsLoading(true);
try {
const response = await fetch(
`${process.env.REACT_APP_API_URL}/auth/register`,
{
method: "POST",
body: formData,
}
);
const data = await response.json();
if (data.status === "success") {
const { token, user } = data.data;
dispatch(setCurrentUser(user, token));
navigate("/choose-actor");
} else {
setAlertConfig({
type: "warning",
message: data.message,
show: true,
});
}
} catch (error) {
console.log(error);
setAlertConfig({
type: "danger",
message: "Ocorreu algum erro",
show: true,
});
} finally {
setIsLoading(false);
}
};
return
...html
{alertConfig.show && <Alert {...alertConfig} />}
...more html
As you can see, i am changing the configuration for the alert inside inside the function that executes the http request, and i have to do the save for every page that performs this action.
I looking for a design patter where i dont have to repeat myself.
Hope my question is clear.
