Sending requests to web servers is one of the most common things developers do on the front-end side of web development. For example, uploading a new Instagram image, creating a Facebook post, sending a tweet, or signing up or logging in to a new website requires sending a request to a server.
Axios is mainly an open-source library the developers mostly use to send all these types of requests by offering the promise-based HTTP client method named Post. You can hire React expert to guide you in correctly implementing post form data using Axios. However, in this Post, we will discuss the steps to post form the data using Axios.
An Introduction to the Axios
One of the primary roles of the Axios is to make asynchronous HTTP requests to the Rest endpoints in Node.js and browsers. As Axios is among the lightweight HTTP client for React and Node.js, it offers the ability to reap maximum advantage of JavaScript’s await and async. Moreover, it shares a similarity with the native JavaScript Fetch API. As a result, it has gained popularity among developers because it offers several methods such as PUT, POST, GET, PATCH, DELETE, etc. Though in this article, we will only talk about the POST method.
Understanding the POST Method
To understand the POST method clearly, we must consider a few things. For example, when we log into Facebook, it asks people either to log in or sign up if they already have a Facebook account. Hence, we need to fill in all the required form details to send them to the server. Then, the server thoroughly checks to proceed to the app. They will also respond by giving an error message if the details are incorrect. So, Axios POST is the method that makes the entire process happen. When you hire React expert, the expert will form a POST code that looks like- axios.post(url[, data[, config]]).
Axios POST will take three parameters from the code mentioned above: the data, url, and config. Url is where the developers send the request, while the data encapsulates the part of the request that developers send to the url. Finally, the config is the last parameter where the developers specify the permissions, content header type, etc. All of these three methods are in the object format.
Why Should You use Axios?
You might wonder why you need to use Axios over fetch () of the native JavaScript method. It is so because Axios offers a list of benefits of using post form data. First, it allows the developers to work with the JSON data by default. It is far better than the fetch () as you need to convert the request body to a JSON string. Finally, when you hire React expert, they can use Axios both on the client and server.
The best part of using Axios is that it allows requesting timeouts and canceling requests. It has come up with better error handling as it throws many errors, including network errors. Additionally, Axios offers broader browser support compared to the fetch (). Also, it has the power to intercept HTTP requests. Several things make the Axios Dev-friendly. Some of them are:
- In Axios, you can cancel requests.
- You can transform the request and the response to the data
- It supports the Promise API
- Intercepts response and request
- It offers automatic transforms for the JSON data
Steps to Post Form Data Using Axios
The steps to post form data with the help of Axios is pretty simple if you know the correct process. When you hire React expert, the developer will follow these steps to post the form data using Axios successfully.
Step 1: Install the Axios to Add This To The React Project
If the user has not installed the Axios yet, then the first thing you need to do is install the Axios.. It will add the dependency of the Axios to the package.JSON file of the project. You can run either npm i Axios or yarn add Axios command to install the Axios. After you complete the installation, you can go to the App.js file. Then, you must import the Axios from the package you have installed before using it.
Step 2: Submit the Form With The Axios
To use the Axios, you just have to install the Axios dependency. Below we have mentioned the code that shows how you can submit the form with the help of Axios.
Step 3: Submit Your Form Using Axios With Files or Images
If the Axios post involves images or files, Axios will accept the specific object with the header properties. As a result, it will allow you to do the proper customization the post request. For better guidance, you can hire React expert.
axios({
method: "post",
url: "http://localhost:8082/user/create",
data: person,
headers: { "Content-Type": "multipart/form-data" },
})
.then((response) => {
setResponse(response.data)
console.log(response.data)
})
.catch(function (error) {
console.log(error);
});
Step 4: Form an Express API using Axios
After posting the form by following the simple steps mentioned above, it is time to form a simple express API. After identifying the destination of your API, you must form a simple express server to manage the posting request. To do that, you must create a specific folder for hosting the server. For example, you name the folder express. Then, in the terminal, open the express folder to run the follwoing commands for installing.
- npm init
- npm install express – save
Step 5: Install the Nodemon and Cors
Nodemon is one of the popular filesystem watchers. The primary role of nodemon is to allow the deployment of the node application after identifying changes in the file system.
npm install – save –dev nodemon
Then, include the starter your scrips in the package.json after installing.
“start” : “node index.js” ,
“dev” : “nodemon index.js”
When you install the cors, it will further enables the cross-origin sharing resource. The browser blocks the api calls across several domains by default.
Step 6: Create the Server
The final step is to form the index.js. After that, you must run the npm dev to begin the server in its development mood. Then, you need to run the npm start. Then, your React.js app will be ready for sending the request to express backend.
Conclusion
Posting form data has become extremely simple using Axios. It performs better compared to the native Fetch API. All you need to do is follow the steps properly to post using Axios successfully. Otherwise, you can hire React expert to get professional help in the entire process.
