10 Features You Should Look for in a Modern React Form Library

Forms are the backbone of most web applications — from login pages and checkout flows to dashboards and data collection tools. Choosing the right form library can make or break developer productivity and user experience.

In this article, we’ll cover 10 must-have features in a modern React form library and show how react-forminate implements each of them with practical examples.

1. Easy Setup & Provider Pattern

A good library should make initialization simple, without forcing boilerplate.

With react-forminate, you wrap your app in the FormRegistryProvider once:

import { StrictMode } from "react";
import { createRoot } from "react-dom/client";
import App from "./App";

import { FormRegistryProvider } from "react-forminate";
import "react-forminate/dist/react-forminate.css";

createRoot(document.getElementById("root")!).render(
  <StrictMode>
    <FormRegistryProvider>
      <App />
    </FormRegistryProvider>
  </StrictMode>
);

✅ No extra Redux, no context wiring — just plug and play.

2. JSON Schema Driven Forms

A modern library should allow forms to be declarative, not hand-coded.
In react-forminate, you define fields via JSON:

const formSchema = {
  formId: "userForm",
  fields: [
    { id: "firstName", type: "text", label: "First Name", required: true },
    { id: "age", type: "number", label: "Age", min: 18 },
    { id: "newsletter", type: "checkbox", label: "Subscribe", options: [{value: "yes", label: "Subscribe the newsletter"}] },
  ],
};

import { DynamicForm } from "react-forminate";

<DynamicForm formData={formSchema} />;

✅ Schema-driven forms reduce repetition and make forms reusable.

3. Strong Validation System

A library should support synchronous, asynchronous, and custom strategies. With react-forminate, you can register validation strategies globally:
(While react-forminate has pre-built validations like min/max, email, password, etc., which greatly reduces coding.)

import { validationEngine, type ValidationResponseType } from "react-forminate";

//International Bank Account Number validation
class IbanValidationStrategy {
  validate(value: string): ValidationResponseType {
    const ibanRegex = /^[A-Z]{2}\d{16}[A-Z0-9]{1,30}$/;
    const isFormatValid = ibanRegex.test(value);
    return {
      isValid: isFormatValid,
      message: isFormatValid ? "" : "Invalid IBAN format",
    };
  }
}

validationEngine.registerStrategy("IBAN", new IbanValidationStrategy());

And use it in schema:

{
  "id": "iban",
  "type": "text",
  "label": "IBAN",
  "validation": { "type": "IBAN" }
}

✅ Validation is modular, testable, and extensible.

4. Conditional Fields & Dynamic Visibility

Modern UIs often show fields based on user input.

{
  "id": "spouseName",
  "type": "text",
  "label": "Spouse Name",
  "visibility": {
    "dependsOn": "maritalStatus",
    "condition": "equals",
    "value": "married"
  },
  "required": true
}

✅ Forms react dynamically to user choices.

5. API-driven Options

Forms should support remote data sources for selects, grids, etc.

{
   fieldId:"country",
   type:"select",
   label:"Country",
   dynamicOptions: {
        endpoint: "https://api.first.org/data/v1/countries",
        transformResponse: (res) => {
          return Object.values(res.data).map((country: any) => ({
            value: country.country,
            label: country.country,
          }));
        },
        fetchOnInit: true,
        pagination: {
          limit: 300, //because we sure there is no more than 300 countries in the world!
        },
      },
   },
}

✅ Populate fields directly from APIs, with mapping support (transformResponse).

6. Support for All HTML Attributes

Every form library should not block HTML.

{
  "id": "email",
  "type": "text",
  "label": "Email",
  "required": true,
  "autoComplete": "email",
  "placeholder": "[e-mail]"
}

✅ All attributes (autoComplete, contextMenu, etc.) flow naturally.

7. Access to Values and Form Actions Anywhere

Sometimes you need to read/write form values programmatically.

import { useFormValues, useFormReg } from "react-forminate";

const Example = () => {
  const values = useFormValues("userForm"); //useFormValues Gets form Id
  const forms = useFormReg(); //Returns the states of all used forms inside the app

  return (
    <button onClick={() => console.log(values, forms)}>
      Debug Form State
    </button>
  );
};

✅ You can grab values anywhere in the tree.

8. Customizable UI & Skeleton Loading

Modern apps need loading states and the ability to swap skeletons.

const CustomSkeleton = () => {
  return (
    <div className="animate-pulse flex flex-col space-y-4 mb-4">
      <div className="h-6 bg-indigo-400 rounded w-1/3"></div>
      <div className="h-6 bg-indigo-400 rounded w-full">Loading...</div>
    </div>
  );
};

const FormData: FormDataCollectionType = {
  formId: "SimpleForm",
  title: "Simple Form Example",
  options: {
    skeleton: {
      visible: true,
      component: <CustomSkeleton />,
    },
  },
  fields: [...]
}

✅ Built-in skeletons, or inject your own.

9. Extensibility for Custom Fields

If a library doesn’t let you add new field types, it’s limiting.

With react-forminate, you can register your own:

import { registerField, useField } from "react-forminate";

const ColorPickerField = (props) => {
   const { fieldId, eventHandlers, fieldParams, setValue, values } = useField(props);

   return <input type="color" value={values[fieldId]} onChange={e => onChange(setValue(e.target.value))} {...eventHandlers.htmlHandlers} {...fieldParams} />
};

registerField("colorPicker", ColorPickerField);

Then just use in schema:

{ "id": "favColor", "type": "colorPicker", "label": "Favorite Color" }

✅ You’re not locked in to defaults.

10. Complex Layout Support

Forms aren’t always a single column. A solid library should allow grid-based layouts.

const formData = {
  formId: "formWithLayout1",
  options: {
    layout: {
      layoutType: "grid",
    },
  },
  fields: [
    { id: "firstName", type: "text", gridColumn: 6 },
    { id: "lastName", type: "text", gridColumn: 6 },
    { id: "address", type: "textarea", gridColumn: 12 },
  ],
};

✅ react-forminate supports grid-based/flexbox-based schema layouts with Tailwind utility props or custom styling.
