海外TECH	DEV Community	Understanding Axios POST requests	https://dev.to/logrocket/understanding-axios-post-requests-48o7	Understanding Axios POST requestsWritten by Chimezie Innocent ️Sending requests to a web server is one of the most common things we do on the frontend side of web development Creating a Facebook post uploading a new Instagram image sending a tweet or logging in and signing up on new websites these scenarios all send requests to a server Axios is an open source library that helps us send all these kinds of requests by providing a promised based HTTP client method called POST In this article we ll learn how to use the Axios POST method both in vanilla JavaScript and in a framework like React Introduction to AxiosThe Axios library makes asynchronous HTTP requests to REST endpoints in browsers and Node js Because Axios is a lightweight HTTP client for both Node js and browsers it gives users the ability to take advantage of JavaScript s async await Axios is also quite similar to the native JavaScript Fetch API It offers a lot of methods like POST PUT PATCH GET DELETE and so on However in this article we will only be looking at the POST method To understand using the POST method let s consider the following scenario Take logging into Facebook for example When we first start using the app it first asks us to either sign up or log in if we already have an account To do both we must fill in the required form details and send them to a server This server then checks what we entered and proceeds to take us into the main app or respond with an error message if the details are incorrect Axios POST is the Axios method that allows us to do that Below is what an Axios POST request looks like axios post url data config From the code above Axios POST takes three parameters the url data and config The url is the server path we send the request to note that it is in string format The data then encapsulates the request body that we re sending or parsing to the url This is in object format which means it has a key and value pair The key is the schema the server accepts while the value is any data type we parse config is the third parameter where we specify the header content type authorization and so on this is also in object format Now that we understand a bit about what Axios is and what its POST method does let s go ahead and see how to use it Axios tutorial prerequisitesBefore proceeding it is of utmost importance that you have an understanding of React and how React form elements work You can read more about forms in React here Why use Axios You might wonder why you should use Axios over the native JavaScript fetch method Comparatively Axios has some advantages over fetch First Axios allows us to work with only one promise then and with JSON data by default unlike in the Fetch API where we must first convert the request body to a JSON string in the first promise With Fetchfetch url then response gt response json then data gt console log data catch error gt console log error With Axiosaxios get url then response gt console log response catch error gt console log error Secondly Axios can be used on the client as well as on the server unlike the Fetch API Axios functions are also named to match the HTTP methods To perform a POST request you use the post method and so on axios post to perform POST requestaxios get to perform GET requestaxios put to perform PUT requestaxios delete to perform DELETE requestaxios patch to perform PATCH requestOther reasons to use Axios POST over the Fetch API include the following Axios allows canceling requests and requesting timeouts which fetch does not allow Axios has better error handling by throwing a wide range of errors including network errors Axios has the ability to intercept HTTP requests Axios has a wider browser support Using Axios POSTEarlier in this article we mentioned that we will cover how to use the Axios POST method both in vanilla JavaScript and in React so we will start with the former and then proceed to the latter Note that most of this article will focus on working with React and we will use the reqres in dummy API for our calls Axios POST in vanilla JavaScriptTo use Axios in vanilla JavaScript we must first add the CDN link in the HTML before using it in the script file Let s start by creating two files to use index html and index js index html lt DOCTYPE html gt lt html gt lt head gt lt title gt Parcel Sandbox lt title gt lt meta charset UTF gt lt head gt lt body gt lt div id app gt lt h gt Login Account lt h gt lt form action gt lt label for email gt Email lt input type email name id email gt lt label gt lt label for password gt Password lt input type password name id password gt lt label gt lt button id btn gt Login lt button gt lt form gt lt div gt lt script src gt lt script gt lt script src index js gt lt script gt lt body gt lt html gt This HTML file creates a simple login page with two input fields the email and the password fields and a login button At the bottom just above the index js link we added the Axios CDN Next we head over to our index js file that we created and get the email input password input and button elements using their Ids We can then add an onClick event listener that triggers the function whenever we click the button index jsconst emailInput document getElementById email const passwordInput document getElementById password const btn document getElementById btn btn addEventListener click gt const email emailInput value const password passwordInput value axios post email email password password then response gt console log response From our reqres in dummy API use eve holt reqres in and cityslicka as the email and password values respectively If you click the login button you will get a response token in your console with a status code telling you the POST request was successful Using Axios POST in ReactWe can now perform the same POST request we just did in the vanilla JavaScript example in React To use Axios in React we must install the Axios package using npm or yarn In your terminal install Axios by running either of the following commands npm install axios yarn add axiosWith Axios installed let s go to our App js file Unlike in vanilla JavaScript we must first import Axios from the Axios package we installed before using it Then in our handleSubmit function let s call Axios with the POST method just as we did in the vanilla example import React useState from react import axios from axios const App gt const data setData useState email password const handleChange e gt const value e target value setData data e target name value const handleSubmit e gt e preventDefault const userData email data email password data password axios post userData then response gt console log response status console log response data token return lt div gt lt h gt Login Account lt h gt lt form onSubmit handleSubmit gt lt label htmlFor email gt Email lt input type email name email value data email onChange handleChange gt lt label gt lt label htmlFor password gt Password lt input type password name password value data password onChange handleChange gt lt label gt lt button type submit gt Login lt button gt lt form gt lt div gt The above code is a practical example of where and how we can use the Axios POST call Let s look at another example where we create a new user or register as a new user App jsimport React useState from react import styles css import axios from axios const App gt const state setState useState name job const handleChange e gt const value e target value setState state e target name value const handleSubmit e gt e preventDefault const userData name state name job state job axios post userData then response gt console log response status console log response data return lt div gt lt h gt Register or Create new account lt h gt lt hr gt lt form onSubmit handleSubmit gt lt label htmlFor name gt Name lt input type text name name value state name onChange handleChange gt lt label gt lt label htmlFor job gt Job lt input type text name job value state job onChange handleChange gt lt label gt lt button type submit gt Register lt button gt lt form gt lt div gt You can also create a styles css file and copy the CSS styling below to style the app It s nothing fancy but makes the interface view a bit cooler styles cssbody padding margin box sizing border box font family sans serif h text align center margin top px margin bottom px hr margin bottom px width border px solid palevioletred background color palevioletred form border px solid black margin padding px display flex flex direction column align items center justify content center label width text transform uppercase font size px font weight bold input display block margin bottom px height vh width button padding px px text transform uppercase cursor pointer With that we have our registration app to utilize our POST method As previously stated one of the advantages of using Axios over the native Fetch API is that it allows us to handle error responses better With Axios it catches errors in the catch block and allows us to check for certain conditions to see why the error occurs so we can know how to handle them Let s see how we can do that below using the first example const App gt const data setData useState email password const handleChange e gt const value e target value setData data e target name value const handleSubmit e gt e preventDefault const userData email data email password data password axios post userData then response gt console log response catch error gt if error response console log error response console log server responded else if error request console log network error else console log error return lt div gt lt h gt Login Account lt h gt lt form onSubmit handleSubmit gt lt label htmlFor email gt Email lt input type email name email value data email onChange handleChange gt lt label gt lt label htmlFor password gt Password lt input type password name password value data password onChange handleChange gt lt label gt lt button type submit gt Login lt button gt lt form gt lt div gt In the first error condition we check if there is a response that is if our request was sent and the server responded The errors we can get here range from a error telling us the user does not exist or there are missing credentials a error telling us the page was not found to a error telling us the page is unavailable and so on In the second error condition we check to see if the request was made but no response was received from the server A network error or offline internet network is usually the reason for this error And finally if the error received does not fall under these two categories then the last error block catches it and tells us what happened We can also use error toJSON to make our error response more readable Making multiple concurrent GET requestsThis section is a bonus section that covers how to perform multiple GET requests concurrently using Axios with error handling Since Axios returns a promise we can perform multiple GET requests using Promise all const getFirstUsers axios get const getSecondUsers axios get Promise all getFirstUsers getSecondUsers then response gt const firstResponse response const secondResponse response However Axios has a built in function called all that works just as Promise all const firstRequest axios get const secondRequest axios get const thirdRequest axios get axios all firstRequest secondRequest thirdRequest then axios spread res gt const firstRes res const secondRes res const thirdRes res console log firstRes secondRes thirdRes catch error gt if error response the request was made and the server responded with a status code console log error response console log error response status else if error request the request was made but no response was received console log network error else something happened when setting up the request console log error You can perform the GET request on any number of APIs of your choice by wrapping it all inside Axios all just like in Promise all It then calls them as an array and returns a promise Axios also allows you to spread the response The above code however looks a bit long and unreadable so let s rewrite it using Promise all and make it more readable let API Promise all API map api gt return axios get api then res gt console log res catch error gt if error response the request was made and the server responded with a status code console log error response console log error response status else if error request the request was made but no response was received console log network error else something happened when setting up the request console log error toJSON Now it looks shorter and more readable What we did here is simple we added all the endpoints we tried to call in an array called API We then mapped through the API array and performed the GET request on each of them All responses are now resolved under Promise all which means that Promise all waits for all input promises to resolve before returning a promise ConclusionWe have now seen what makes Axios better than the native Fetch API by performing Axios POST requests in vanilla JavaScript and React We also looked at how Axios allows us to handle our errors better and perform multiple requests using Axios all and Promise all However note that Axios all as it still works today has been deprecated and it s advised to use Promise all instead This includes by extension the Axios spread Hopefully you understood all we did in this article and can now perform POST and concurrent GET requests comfortably Gracias Full visibility into production React appsDebugging React
