Top 5 Projects Compared

form
5,864

TanStack/form is a lightweight, type-safe, and framework-agnostic form management library for JavaScript applications.

Code Example

import { useForm } from '@tanstack/react-form'

const form = useForm({ defaultValues: { name: '' } })
const { Field } = form

Pros

Offers excellent TypeScript support and type safety out of the box
Framework-agnostic, allowing use with various JavaScript frameworks
Provides a simple and intuitive API for form management

Cons

Less mature compared to some other form libraries, potentially with fewer community resources
May require more manual setup for complex form scenarios compared to feature-rich alternatives
Lacks built-in UI components, requiring developers to create their own form elements

survey-library
4,564

SurveyJS is a comprehensive JavaScript library for creating dynamic, customizable surveys and forms.

Code Example

const survey = new Survey.Model(surveyJSON);
survey.onComplete.add((sender, options) => {
    console.log("Survey results:", sender.data);
});

Pros

Offers a rich set of question types and advanced features like conditional logic and branching.
Provides a visual survey builder tool for easy survey creation without coding.
Supports multiple frameworks (React, Vue, Angular) and can be used with plain JavaScript.

Cons

Has a steeper learning curve compared to simpler form libraries like TanStack/form or ngx-formly.
May be overkill for basic form needs, as it's primarily designed for complex surveys.
Requires a commercial license for certain advanced features and removing the SurveyJS branding.

ngx-formly
2,934

ngx-formly/ngx-formly is a dynamic form library for Angular that allows developers to create complex forms from simple JSON configurations.

Code Example

import { FormlyFieldConfig } from '@ngx-formly/core';

const fields: FormlyFieldConfig[] = [
  { key: 'name', type: 'input', templateOptions: { label: 'Name' } },
  { key: 'email', type: 'input', templateOptions: { label: 'Email', type: 'email' } }
];

Pros

Seamless integration with Angular, providing a native experience for Angular developers
Extensive customization options, allowing for complex form layouts and field types
Strong community support and regular updates, ensuring compatibility with the latest Angular versions

Cons

Steeper learning curve compared to some simpler form libraries
Less suitable for non-Angular projects, unlike more framework-agnostic options like TanStack/form or SurveyJS
May require more setup and configuration for basic forms compared to simpler alternatives

jsonforms
2,554

JSONForms is a declarative framework for efficiently building form-based web UIs using JSON Schema and UI Schema.
