Creating a registration form
The registration form is divided into two components in this tutorial i.e. H. Header and registration form being renderedapplication.js
.
Create a new folder namedcomponents
in the src folder. The following files are created in the component folder:
header.js
registroForm.js
style.css
Note: In exchange, JSX is used instead of HTML code. JSX is a markup language that includes HTML and JavaScript.
In themheader.js
write the following code. You can also copy and paste from here.
import React von 'react';function Header() { hand back( <Navigation class="bg-dark navbar-dark navbar"> <division class name="Zeile Spalte-12 d-flex Justify-Content-Center Text-White"> <h3>recording</h3> </div> </navigation>)}Export Lack Header;
Now your header is ready. In order to display it on the website, you need to import themheader.js
inapplication.js
. Write the following code in theapplication.js
.
import Logo von './logotipo.svg';import './Aplicación.css';import Header von './components/headers';function App() { hand back( <division class name="App"> <Header/> </div>);}Export Lack App;
If you wrote the code above correctly, the web page will look like this:
;
Proceed to the next component, the registration form.
Contains the following fields:
- first name
- surname
- E-mail address
- Clave
- Confirm Password
- Submit button
Then write the following code in theregistroForm.js
to create the body of the form.
import React, {useState}von 'react';import './estilo.css'function registration form() { hand back( <division class name="the picture"> <division class name="Body shape"> <division class name="username"> <label class name="form_label" through="First name">First Name </caption> <Entry class name="form_entry" write="Text" I WOULD="First name" position marker="First name"/> </div> <division class name="Surname"> <label class name="form_label" through="Surname">Last Name </caption> <Entry write="Text" Name="" I WOULD="Surname" class name="form_entry"position marker="Surname"/> </div> <division class name="Email"> <label class name="form_label" through="Email">Email </caption> <Entry write="Email" I WOULD="Email" class name="form_entry" position marker="Email"/> </div> <division class name="piano"> <label class name="form_label" through="piano">Clave </caption> <Entry class name="form_entry" write="piano" I WOULD="piano" position marker="Clave"/> </div> <division class name="Confirm Password"> <label class name="form_label" through="Confirm Password">Confirm Clave </caption> <Entry class name="form_entry" write="piano" I WOULD="Confirm Password" position marker="Confirm Password"/> </div> </div> <division class="Footlines"> <Taste write="Submit" class="btn">recording</Taste> </div> </div>)}Export Lack registration form;
Your basic shape structure is complete but still needs some styling. To design your form, write the following code instyle.css
.
Note: Don't forget to import
style.css
inregistroForm.js
. It has already been added in this tutorial.
Body{ background:#bdc3c7;/* support for old browsers */ background:-webkit-linear gradient (a Right,#2c3e50,#bdc3c7);/* Chrom 10-25, Safari 5.1-6 */ background: linear gradient (a Right,#2c3e50,#bdc3c7);/* W3C, IE 10+/ Edge, Firefox 16+, Chrome 26+, Opera 12+, Safari 7+ */}.the image{ background color:White; Table radio:5Pixel; ancho:550Pixel; Rand:20Pixel Auto; filling:20Pixel; /* Height: 600px; 🇧🇷}.shape body{ aligned text:links; filling:20Pixel 10Pixel;}.shape body > *{ filling:5Pixel;}.form_label{ ancho:40%;}.input form{ ancho:60%;}.Footer{ aligned text:Center;}
Add this componentapplication.js
.
import Logo von './logotipo.svg';import './Aplicación.css';import Header von './components/headers';import registration form von './components/registration form'function App() { hand back( <division class name="App"> <Header/> <registration form/> </div>);}Export Lack App;
Implementation of hooks in the registration form.
This section provides an overview of hooks in respond.js. For more details, I recommend you to read the official React documentation first.
useState
Hook is used to hold a state of a variable that you can dynamically updateset state
.
Now go to your form where you need to maintain the status of each input in the form. When users click the submit button, they can submit the data to the backend API. In vanilla JavaScript this is done withdocument.getElementById("demo").value
As we react, we have a status for each input and update it on each onChange event.
importuseState
jset state
responsive hook at the top of our code. Now we can create a state for all input elements.
Constantly[first name,insert name]= useState(Null); Constantly[surname,establecerApellido]= useState(Null); Constantly[Email,Set email]= useState(Null); Constantly[Clave,set key]= useState(Null); Constantly[Confirm Password,Set confirmation password]= useState(Null);
We will add two attributes inEntry
Label to hold the state variable, i.e.
- bravery
- upon change
bravery: The value attribute contains the name of the fields we use when declaring states.
upon change: Write the following code for the onChange attribute.
upon change ={(mi) =>handleInputChange(mi)}
<Entry class name="form_entry" write="Text" bravery={first name}upon change ={(mi) =>handleInputChange(mi)}I WOULD="First name" position marker="First name"/> <Entry write="Text" Name="" I WOULD="Surname" bravery={surname}class name="form_entry" upon change ={(mi) =>handleInputChange(mi)}position marker="Surname"/><Entry write="Email" I WOULD="Email" class name="form_entry" bravery={Email}upon change ={(mi) =>handleInputChange(mi)}position marker="Email"/><Entry class name="form_entry" write="piano" I WOULD="piano" bravery={Clave}upon change ={(mi) =>handleInputChange(mi)}position marker="Clave"/><Entry class name="form_entry" write="piano" I WOULD="Confirm Password" bravery={Confirm Password}upon change ={(mi) =>handleInputChange(mi)}position marker="Confirm Password"/>
In the following code, within the onChange event, the function is calledhandleInputChange
which handles the status updates of all input changes.
Constantly handleInputChange =(mi) => { Constantly{I WOULD,bravery}= mi.objective; and(I WOULD === "First name"){ insert name(bravery);} and(I WOULD === "Surname"){ establecerApellido(bravery);} and(I WOULD === "Email"){ Set email(bravery);} and(I WOULD === "piano"){ set key(bravery);} and(I WOULD === "Confirm Password"){ Set confirmation password(bravery);}}
In this function, you will get the ID and the value entered in the input field. As soon as you type something there, the status of that particular field will be updated. This way you keep all the states so that you can send all the necessary information to the backend APIs on the submit button.
in this tutorialhandle send
The function in which you get all the values that are filled in the form is used. This function is used to connect the app to Firebase. This is the final code for the registration form, containing all the details you've learned in the tutorial so far.
import React, {useState,set state}von 'react';import './estilo.css'function registration form() { Constantly[first name,insert name]= useState(Null); Constantly[surname,establecerApellido]= useState(Null); Constantly[Email,Set email]= useState(Null); Constantly[Clave,set key]= useState(Null); Constantly[Confirm Password,Set confirmation password]= useState(Null); Constantly handleInputChange =(mi) => { Constantly{I WOULD,bravery}= mi.objective; and(I WOULD === "First name"){ insert name(bravery);} and(I WOULD === "Surname"){ establecerApellido(bravery);} and(I WOULD === "Email"){ Set email(bravery);} and(I WOULD === "piano"){ set key(bravery);} and(I WOULD === "Confirm Password"){ Set confirmation password(bravery);}} Constantly handle send =() => { console.log in(first name,surname,Email,Clave,Confirm Password);} hand back( <division class name="the picture"> <division class name="Body shape"> <division class name="username"> <label class name="form_label" through="First name">First Name </caption> <Entry class name="form_entry" write="Text" bravery={first name}upon change ={(mi) =>handleInputChange(mi)}I WOULD="First name" position marker="First name"/> </div> <division class name="Surname"> <label class name="form_label" through="Surname">Last Name </caption> <Entry write="Text" Name="" I WOULD="Surname" bravery={surname}class name="form_entry" upon change ={(mi) =>handleInputChange(mi)}position marker="Surname"/> </div> <division class name="Email"> <label class name="form_label" through="Email">Email </caption> <Entry write="Email" I WOULD="Email" class name="form_entry" bravery={Email}upon change ={(mi) =>handleInputChange(mi)}position marker="Email"/> </div> <division class name="piano"> <label class name="form_label" through="piano">Clave </caption> <Entry class name="form_entry" write="piano" I WOULD="piano" bravery={Clave}upon change ={(mi) =>handleInputChange(mi)}position marker="Clave"/> </div> <division class name="Confirm Password"> <label class name="form_label" through="Confirm Password">Confirm Clave </caption> <Entry class name="form_entry" write="piano" I WOULD="Confirm Password" bravery={Confirm Password}upon change ={(mi) =>handleInputChange(mi)}position marker="Confirm Password"/> </div> </div> <division class="Footlines"> <Taste click={()=>handle send()}write="Submit" class="btn">recording</Taste> </div> </div> )}Export Lack registration form

Connecting the registration form to Firebase
Live!! Your registration form is complete, but you need to save the information registered by the user, which is done using Firebase.
Good news, to use Firebase you don't need to install an app, you just need a Google/Gmail mail id.
Here's how to connect your signup form to Firebase. To do this, you must do the following.click hereTo start.
- To start your project, click Add project.
- Give your project a name. This tutorial uses the registration form.
Then click Next.
- Then you need to select the default account for Firebase.
Then click on “Create project”
Now your project file is ready. You will use it to build the database in real time.
- To perform a real-time data setup, select "Real-time Database" in the left pane.
Then click the "Create Database" button. The Configure Database dialog box appears.
You go to the next step and leave the default save location. Since it is in development mode, it will select and check "Start in test mode".
Now your database is ready to store data in real time.
You need to create a link between your reaction project and the real-time data.
- To do this, go to the project overview in the left pane and then click the Web button.
- You need to register your app and give it a nickname. In this tutorial the "Registration Form" is used, you can choose any name of your choice.
Since you are not hosting, DO NOT select the "Configure Firebase hosting for this app" option and then click Register App.
- Now you need to add the package to your React app. From the terminal or command prompt, change to the directory where your project is located and run this command.
Install npm Firebase
Create a new file named "firebase.js" in the src folder where you copy the code.
First you need to initialize Firebase in your project. Then import the database into your code.
- Enter the following statement to import the data.
import{retrieve database}von "Firebase/Database"
- To use this database in your registration form component, you must export it. Add the following code.
Export Constantly Database = retrieve database(App);
In the registration form component, import the following files.
import{Database}von '../firebase'import{referee,To press,Niño,To update}von "Firebase/Database";
- To save the input entered by the user, you need to paste the following code into the Handle Submit function that you ran earlier.
Constantly handle send =() => { To let Object ={ first name : first name, surname:surname, Email:Email, Clave:Clave, Confirm Password:Confirm Password,} Constantly new contribution key = To press(Niño(referee(Database),'Releases')).key; Constantly Update ={}; Update['/' + new contribution key]= Object hand back To update(referee(Database),Update);}
Now you have successfully completed the steps.
Finally, let's see how it works.
Enter your details in the form and then click Register.
To verify the input, you can view it in your Firebase account. It will appear as shown below.
Conclusion
Congratulations, you have successfully learned how to use React.js to create, structure and style a signup form. It also used React Hooks to maintain state so the data could be stored in the Firebase real-time database.
Happy coding!
