How It Works

SurveyJS Form Library renders forms from JSON definitions directly in your web application. It runs in the browser and does not require a SurveyJS backend, so you retain control over form definitions, submitted responses, and data storage.

Your application can:

1. Create or load a SurveyJS JSON form definition.
2. Render it with SurveyJS Form Library.
3. Collect responses in the browser.
4. Send submitted data to your backend.
5. Store it in the database or service of your choice.

Package Architecture

SurveyJS Form Library separates form logic from rendering. The framework-independent survey-core package provides the form model, validation, conditional logic, calculations, navigation, localization, and other core behavior. Framework-specific packages such as survey-react-ui, survey-angular-ui, and survey-vue3-ui render that model in React, Angular, and Vue 3 applications. Installing a rendering package brings survey-core with it.
