海外TECH	DEV Community	Sending data from React to Flask.	https://dev.to/dev_elie/sending-data-from-react-to-flask-apm	Sending data from React to Flask In our previous article on connecting a React frontend to a Flask backend we saw how to fetch data from Flask API and then displaying it on the browser in this continuation article we ll explore how to send data to a Flask backend from React then update the UI with the new data Check my GitHub for the complete codes used in this guide Part Configuring the Flask backend routes pyBefore we continue Let s alter our Flask routes py to accept input from the React frontend then commit the database We ll add the following lines of code to our routes py file app route add methods POST strict slashes False def add articles title request json title body request json body article Articles title title body body db session add article db session commit return article schema jsonify article The function above basically gets an article title and description in json format adds the record to the database and then commits i e saves Part Configuring the React frontend In contrast to the last tutorial we will make some changes to our project by introducing a Components directory Then we ll add some new files one to manage our API services and another to display a form to the UI as well as to handle our interaction with the APIService which provides our data to Flask Components APIService jsexport default class APIService Insert an article static InsertArticle body return fetch http localhost add method POST headers Content Type application json body JSON stringify body then response gt response json catch error gt console log error To better organize our files and increase efficiency we conduct all of the Flask API services in a single file and then call the methods as needed The code above requests our Flask routes which handle data insertion and then posts our JSON stringified article title and description Flask takes care of the rest under the hood Components Form jsimport useState from react import APIService from Components APIService Because we ll require the React useState hook and the APIService component we make them available as seen above const Form props gt const title setTitle useState const body setBody useState const insertArticle gt APIService InsertArticle title body then response gt props insertedArticle response catch error gt console log error error const handleSubmit event gt event preventDefault insertArticle setTitle setBody return lt div gt Form lt div gt export default Form In the above functional component we just created we do define two sets of variables the title and the article body both are subjected to the useState hook that returns the current states title and body and a function that updates them setTitle and setBody We then invoke the APIService InsertArticle method This call takes our article object from the form submitted by the user as an argument The response is then sent as a parameter to a function insertedArticle that we are yet to create in the later steps inside App js A Parameter is variable in the declaration of function while an argument is the actual value of this variable that gets passed to function StackoverflowIn the handleSubmit function we call insertArticle and then clear the form fields after submission The return statement of the Form component delivers our actual HTML form as illustrated below lt form onSubmit handleSubmit gt lt label htmlFor title className form label gt Title lt label gt lt input type text className form control placeholder Enter title value title onChange e gt setTitle e target value required gt lt label htmlFor body className form label gt Body lt label gt lt textarea className form control placeholder Enter body rows value body onChange e gt setBody e target value required gt lt textarea gt lt button className btn btn primary mt gt Publish article lt button gt lt form gt App jsAs we near completion we need to show the Form component on the UI We ll import it then display it on the UI as shown in the steps below import the componentimport Form from Components Form Previously we passed the response from our APIService InsertArticle as a parameter it s then received on this end Using the spread operator we will combine the newly created article with the available articles The update is initiated using the setArticles method and the result is a list of updated articles update the existing article list const insertedArticle article gt const new articles articles article setArticles new articles We now have our form ready to display on the UI We can make it visible by calling the Form Component while passing to it the the data as props like this lt Form insertedArticle insertedArticle gt Also keeping the form visible all the time isn t ideal so we made it a toggle button define variables for the present state of the form and another to change its state const showForm setShowForm useState false toggle between the two states visible and hidden const toggleShowForm gt setShowForm showForm Trigger the hide show method lt button onClick toggleShowForm className btn btn primary gt Write an article lt i className bi bi pencil square m gt lt i gt lt button gt display the form conditionally showForm amp amp lt Form insertedArticle insertedArticle gt Project previewThank you for reading Please like share and leave a comment below Also do follow my blog to get notified when the next article on editing and deleting the articles we
