Add a Survey to a React Application
This step-by-step tutorial will help you get started with the SurveyJS Library in a React application. To add a survey to your React application, follow the steps below:
- Install the
survey-react-ui
npm Package - Configure Styles
- Create a Model
- Render the Survey
- Handle Survey Completion
As a result, you will create a survey displayed below:
You can find the full code in the following GitHub repository: Get Started with SurveyJS - React.
Install the survey-react-ui
npm Package
The SurveyJS Library for React consists of two npm packages: survey-core
(platform-independent code) and survey-react-ui
(rendering code). Run the following command to install survey-react-ui
. The survey-core
package will be installed automatically because it is listed in survey-react-ui
dependencies.
npm install survey-react-ui --save
Configure Styles
SurveyJS ships with the Modern and Default V2 UI themes illustrated below.
Open the React component in which your survey will be and import a style sheet that implements the required theme.
// Modern theme
import 'survey-core/modern.min.css';
// Default V2 theme
// import 'survey-core/defaultV2.min.css';
To apply the imported theme, call the applyTheme(themeName)
method. Depending on the theme, pass "modern"
or "defaultV2"
as the method's argument. For instance, the following code applies the Modern theme:
import { StylesManager } from 'survey-core';
StylesManager.applyTheme("modern");
Create a Model
A model describes the layout and contents of your survey. The simplest survey model contains one or several questions without layout modifications.
Models are specified by model definitions (JSON objects). For example, the following model definition declares two textual questions, each with a title and a name. Titles are displayed on screen. Names are used to identify the questions in code.
const surveyJson = {
elements: [{
name: "FirstName",
title: "Enter your first name:",
type: "text"
}, {
name: "LastName",
title: "Enter your last name:",
type: "text"
}]
};
To instantiate a model, pass the model definition to the Model constructor as shown in the code below. The model instance will be later used to render the survey.
import { ..., Model } from 'survey-core';
// ...
function App() {
const survey = new Model(surveyJson);
return ... ;
}

import 'survey-core/modern.min.css';
// import 'survey-core/defaultV2.min.css';
import { StylesManager, Model } from 'survey-core';
StylesManager.applyTheme("modern");
const surveyJson = {
elements: [{
name: "FirstName",
title: "Enter your first name:",
type: "text"
}, {
name: "LastName",
title: "Enter your last name:",
type: "text"
}]
};
function App() {
const survey = new Model(surveyJson);
return ...;
}
export default App;
Render the Survey
To render a survey, import the Survey
component, add it to the template, and pass the model instance you created in the previous step to the component's model
attribute:
import { Survey } from 'survey-react-ui';
// ...
const surveyJson = { ... };
function App() {
const survey = new Model(surveyJson);
return <Survey model={survey} />;
}
If you replicate the code correctly, you should see the following survey:

import 'survey-core/modern.min.css';
// import 'survey-core/defaultV2.min.css';
import { StylesManager, Model } from 'survey-core';
import { Survey } from 'survey-react-ui';
StylesManager.applyTheme("modern");
const surveyJson = {
elements: [{
name: "FirstName",
title: "Enter your first name:",
type: "text"
}, {
name: "LastName",
title: "Enter your last name:",
type: "text"
}]
};
function App() {
const survey = new Model(surveyJson);
return <Survey model={survey} />;
}
export default App;
Handle Survey Completion
After a respondent completes a survey, the results are available within the onComplete event handler. In real-world applications, you should send the results to a server where they will be stored in a database and processed. In this tutorial, the results are simply output in an alert dialog:
import { useCallback } from 'react';
// ...
function App() {
const survey = new Model(surveyJson);
const alertResults = useCallback((sender) => {
const results = JSON.stringify(sender.data);
alert(results);
}, []);
survey.onComplete.add(alertResults);
return <Survey model={survey} />;
}
As you can see, survey results are saved in a JSON object. Its properties correspond to the name
property values of your questions in the model definition.
To view the application, run npm run start
in a command line and open http://localhost:3000/ in your browser.

import { useCallback } from 'react';
import 'survey-core/modern.min.css';
// import 'survey-core/defaultV2.min.css';
import { StylesManager, Model } from 'survey-core';
import { Survey } from 'survey-react-ui';
StylesManager.applyTheme("modern");
const surveyJson = {
elements: [{
name: "FirstName",
title: "Enter your first name:",
type: "text"
}, {
name: "LastName",
title: "Enter your last name:",
type: "text"
}]
};
function App() {
const survey = new Model(surveyJson);
const alertResults = useCallback((sender) => {
const results = JSON.stringify(sender.data);
alert(results);
}, []);
survey.onComplete.add(alertResults);
return <Survey model={survey} />;
}
export default App;
