Are you looking for the most effective way to display the messages in react apps? If yes, then go through this guide and gather more ideas about this process. In general, react can be often used to build the extraordinary front end of a wide range of applications. It means that the developers are having many choices from the more number of UI libraries.
In this guide, here you can consider a project based on insurance & litigation technology. Building such applications is very complex, since it has a wide range of reusable components and complicated user flows. So after careful requirement analysis and due diligence, the developers have decided to make use of the MUI – Material UI to extraordinarily develop the front end of the application. To implement this in your app you can hire react developers from BOSC Tech Labs at best prices.
A lot of scratch code is required to be written to complete the simple task from the ant design system to Material UI. The simple task is nothing but the forms with the no out-of-the-box component to work with the other forms.
Developers build some interesting processes with ant like using the imperative writing style of simple logic such as using useNotification, useMessage hooks to show notifications and messages. But the Material UI never provides any kind of out-of-the-box solution.
After the proper Google search, the developer got the idea about the library notistack that let them to grab this style very effectively. But here bundle phobia is the major thing and the developer wants to reduce the footprint of their module too.
By keeping that in mind, they have to make the bare-bone imperative Application Programming Interface (API) to grab this task without any blunders. Then the developer created the simple component known as AppContext. This AppContext will effectively reside in the SRC directory.
It will show you the snackbar component either any component calls the useMessage hook. There are also popular codes you can explore from the official site for the useMessage hook.
It is the useMessage hook’s vanilla version. Then you can effectively customize it as much as you need with the passing parameters that can extend the SnackbarProps. You can also now call this hook anywhere in the component very easily.
In order to manage the snackbar display logic, the developers are using the redux store. If you have any doubt regarding that, you can check out how these developers have configured it with Redux. At last, the developers have added the AppContext component in the root component without any issues.
It is the most intuitive and simple way for creating the imperative style Application Programming Interface using the react hooks for displaying the messages. You must also know some of the interesting facts regarding the AppContext component. The fact is that you can make use of the provider pattern in the React and then wrap the app component around the AppContext.
Here the developers avoid doing it, since it may create some confusion in you. The Context API can wrap the app component and here they are using Redux to carry over the essential process.
Users can also add the hooks for managing the open dialog boxes. Then can handle the async logics around the AppContext. Finally users can maintain the individual components very clean and it can ensure reusability too.
Ways to display error messages in React apps:
In React, the developers are required to work with the external APIs. They grab the data typically from the remote server and then display it in their application.
They find that one popular library to make the http requests to remote servers is Axios. It will let them use some methods such as post (), get () and some more that call the http methods to deal with posting, getting, deleting and updating data from the API.
What are the possible API errors?
One could not assure that all external APIs can be successful. There are some API errors that may occur. It is very possible that the remote server can be down or some blockage prevents the data from being accessed.
During this case, the Axios will return the error. It is the common practice for notifying the user that the error may occur by triggering certain notification like displaying the error message in the web page.
How to display the error message?
When something bad happens, then it is necessary to display the error message at the top of the view. For displaying the message, it is necessary to have the message ready in the component state.
Then it is better to add the errorMessage property to the state object with the empty string value as the initial state. The developers place the Axios call around componentDidMount(). They will set the state to all kinds of value that is returned in the API response when the call is completely successful.
The data will never be available around then () and instead, the catch () method can be called when there is an error. The error object can be returned by the Application Programming Interface and will be passed around there.
During that time, you need to grab the error and then update the errorMessage property in the state via using the setState ().
Display the error message:
There are multiple ways to make it possible but the developers like to create the conditional statement for displaying the error message. Those conditional statements basically require saying:
If having the errorMessage on the state, then display the h3 element through the errorMessage value. But when the errorMessage is empty, then don’t need to display anything. For translating those if conditions into the code, it is best to use the plain old if statement.
Example:
import React from ‘react’;
const Message = ({ type, text }) => {
return (
<div className={`message ${type}`}>
<p>{text}</p>
</div>
);
};
export default Message;
Creating a Message Store
Next, let’s create a message store using React’s Context API. The message store will be responsible for managing and storing the messages in the application. Here’s an example implementation:
import React, { createContext, useState, useContext } from ‘react’;
const MessageContext = createContext();
export const useMessage = () => {
return useContext(MessageContext);
};
export const MessageProvider = ({ children }) => {
const [messages, setMessages] = useState([]);
const addMessage = (type, text) => {
const newMessage = { type, text };
setMessages([…messages, newMessage]);
};
const removeMessage = (message) => {
const updatedMessages = messages.filter((msg) => msg !== message);
setMessages(updatedMessages);
};
const clearMessages = () => {
setMessages([]);
};
const messageContextValue = {
messages,
addMessage,
removeMessage,
clearMessages,
};
return (
<MessageContext.Provider value={messageContextValue}>
{children}
</MessageContext.Provider>
);
};
In this code, we define a MessageContext using createContext() and export a custom hook useMessage() and a MessageProvider component. The MessageProvider component wraps the application’s root component and provides the message context to its descendants.
The message store maintains an array of messages using the useState hook. It provides methods like addMessage() to add a new message, removeMessage() to remove a specific message, and clearMessages() to remove all messages from the store.
Using the Message Component and Message Store
Now that we have our Message component and the MessageProvider, let’s see how we can use them in our app.
import React from ‘react’;
import { useMessage, MessageProvider } from ‘./MessageContext’;
import Message from ‘./Message’;
const App = () => {
const { messages, addMessage } = useMessage();
const handleShowSuccessMessage = () => {
addMessage(‘success’, ‘Operation successful!’);
};
const handleShowErrorMessage = () => {
addMessage(‘error’, ‘An error occurred.’);
};
return (
<div>
<h1>My App</h1>
<button onClick={handleShowSuccessMessage}>Show Success Message</button>
<button onClick={handleShowErrorMessage}>Show Error Message</button>
<div>
{messages.map((message, index) => (
<Message key={index} type={message.type} text={message.text} />
))}
</div>
</div>
);
};
const AppWrapper = () => {
return (
<MessageProvider>
<App />
</MessageProvider>
);
};
export default AppWrapper;
In this code snippet, we import the useMessage hook and the MessageProvider from our message store. Inside the App component, we use the useMessage hook to access the messages array and the addMessage method from the message context.
We define two event handlers, handleShowSuccessMessage and handleShowErrorMessage, which call the addMessage method to add a success or error message to the message store. Know how react chatbots are revolutionising customer service in detail here. To display the messages, we map over the messages array and render a Message component for each message, passing the type and text as props.
Conclusion:
From the above mentioned scenario, now you have got the idea about the way to display the messages in react apps. Hence go to hire react developers and they will follow the most effective way to display the messages in react apps. Without further delay, get help from these app developers now.
