    React form library.



    re-form requires

    • react/react-dom 16.8.3 or later to build your form.

    $ npm install --save @savedo/re-form


    $ yarn add @savedo/re-form


    Basic usage: Creating a react form component with three input fields (name, age, email) validation and values assignment.

    Create your form component:

    import React from 'react';
    import { FormBuilder } from '@savedo/re-form';
    const MyForm = ({ handleSubmit }) => {
      const fields = [
      const fieldOptions = {
        name: {
          label: 'Name:'
        age: {
          label: 'Age:',
          type: 'number'
        email: {
          label: 'E-mail:'
      const validate = (formData) => {
        const errors = {};
        const { name, age } = formData;
        if (!name) {
          errors.name = 'Name is required!';
        if (!age) {
          errors.age = 'Age is required!';
        } else if (Number(age) < 18) {
          errors.age = 'You should be 18 years old or older!';
        return errors;
      return (
          <FormBuilder { ...{ fields, fieldOptions, handleSubmit, validate } } />
    export default MyForm;

    And use form component elsewhere:

    import React from 'react';
    import MyForm from './MyForm';
    const App = () => {
      const handleSubmit = (formData) => {
      return (
        <MyForm handleSubmit={ handleSubmit } />
    export default App;


    The FormBuilder component has props as shown below. It has FormBuilderPropsType<T> type. T refers to your object type having key (Field name, ) / values (Field options ).
