Usage

You can use generic component Form and construct your own view for it:

import {Form, Field} from '@simpozio/contact-form';

const Component = () => {
    const initialValues = {
        name: ''
    }

    const onChange = () => Promise.resolve(console.log('Form Updated'));

    const onValidate = ({fields}) => {
        return Promise.resolve(_.mapValues(fields, value => (value => !!value));
    }

    const onValid = ({fields}) => console.log('Form is valid!', fields);

    const onSubmit = ({values, resetForm}) => {
            return new Promise((resolve, reject) => {
                try {
                   api.post(values)
                    .then(resolve)
                    .then(() => {
                        resetForm()
                    })
                } catch(e) {
                   reject(e);
                };
            }
        }

    const onError = ({error, resetForm}) => {
        console.log(error);
        resetForm();
    };

    return (
        <Form
            initialValues={initialValues}
            onChange={onChange}
            onValid={onValid}
            onValidate={onValidate}
            onSubmit={onSubmit}
            onError={onError}
        >
            {({
                fields,
                formError,
                onChange,
                isValid,
                isSubmitting,
                updateForm,
                submitForm,
                resetForm
            }) => (
                <Field
                    label="name"
                    name="name"
                    field={fields["name"]}
                    onChange={onChange}
                    onBlur={updateForm}
                />

                {formError && <p>{formError}</p>}

                <button onClick={submitForm} disabled={!isValid || isSubmitting}>Submit</button>
                <button onClick={resetForm}>Reset</button>
            )}
        </Form>
    )
}

Or you can you preset with predefined structure, e.g. Short:

import {ShortForm} from '.@simpozio/contact-form/dist/presets';

const StyledShortForm = styled(ShortForm)`
  min-height: 750px;

  @media (max-width: 767px) {
    min-height: 580px;
  }
`;

const Component = () => {
    const fields = {
        name: {
          label: 'Your name',
          initialValue: ''
        },
        phone: {
          label: 'Your phone',
          initialValue: ''
        },
        email: {
          label: 'Your email',
          initialValue: ''
        }
      };

    const onChange = () => Promise.resolve(console.log('Form Updated'));

    const onValidate = ({fields}) => {
        return Promise.resolve(_.mapValues(fields, value => (value => !!value));
    }

    const onValid = ({fields}) => console.log('Form is valid!', fields);

    const onSubmit = ({values, resetForm}) => {
            return new Promise((resolve, reject) => {
                try {
                   api.post(values)
                    .then(resolve)
                    .then(() => {
                        resetForm()
                    })
                } catch(e) {
                   reject(e);
                };
            }
        }

    const onError = ({error, resetForm}) => {
        console.log(error);
        resetForm();
    };

    return (
        <StyledShortForm
          formText={'The price for this model starts at £300,000'}
          bottomText={
            'We collect your data to keep you updated about our reservation program. By submitting this form you agree to the Privacy Policy.'
          }
          fields={fields}
          onValidate={onValidate}
          onChange={onChange}
          onSubmit={onSubmit}
          onError={onError}
        />
    );
};

Styling

Form component is generic, so it don't have any styles. So you need to add styles by yourself with css or with styled component. Preset have default styles, and you can style them in 3 ways:

Theming

Preset accepts theme props, so you can pass theme from your styled-components theme context to preset component:

import {useContext} from 'react';
import styled, {ThemeContext} from 'styled-components';
import {ShortForm} from '@simpozio/contact-form/dist/presets';

const Component = (props) => {
    const theme = useContext(ThemeContext);

    return (
        <ShortForm {...props} theme={theme} />
    )
}

Styled Components

Default styling with styled components

import styled from 'styled-components';
import {ShortForm} from '@simpozio/contact-form/dist/presets';

const StyledForm = styled(ShortForm)`
    color: #fff;
    backgroung-color: #000;
`

const Component = (props) => {
    return (
        <StyledForm {...props} />
    )
}

Custom Styles

Preset supports styles with interpolated string from styled-components:

import styled, {css} from 'styled-components';
import {ShortForm} from '@simpozio/contact-form/dist/presets';

const customStyles = css(({Field, BottomText}) => css`
    ${Field} {
        color: #fff;
        backgroung-color: #000;
    }

    ${BottomText} {
        font-size: 0.8rem;
    }
`

const Component = (props) => {
    return (
        <StyledForm {...props} styles={customStyles} />
    )
}

Properties

Form

Form accepts standard HTML attributes as props: action, method, className. And form have it's own additional properties: fields, isSubmitted, isValid: boolean, error, resetForm

• initialValues: {[key: string]: string} - object with default values for fields
• onChange: ({fields, isSubmitted, isValid}) => Promise<newFields> - callback called when form was updated via updateForm() method. It accepts object with fields and it's values, and optionally can return fields with new values. It can be used to modify fields values in dependency of other values of form changes.
• onValidate: ({fields, isSubmitted, isValid}) => Promise<object> - callback called when form was validated. It accepts object with fields and it's values, and should return fields with boolean values (valid/not valid).
• onValid: ({fields, isSubmitted, isValid}) => void - callback called when form become valid, after onValidate() check
• onSubmit: ({fields, isSubmitted, isValid, resetForm}) => Promise<void> - callback called when form is submitting via submitForm() method. It accepts object with fields and it's values, and optionally can return error that will be passed to onError callback. Also accepts resetForm() method as second argument.
• onError: ({fields, isSubmitted, isValid, error, resetForm}) => void - callback called when form is errored (after onSubmit callback). It accepts error string passed form onSubmit callback as first argument, and resetForm() method as second argument.

• fields - object with field name as keys, and object with value, field error and touched properties as value.
  • value: string - field value
  • error: boolean - validation state of field
  • touched: boolean - becomes true when value of field is different from the initial
• formError: string - string with for error passed from onSubmit callback
• onChange: (name, value) => void - onchange handler for fields, should be passed to onChange callback of fields
• isValid: boolean - becomes true when all fields are valid after onValidate callback,
• isSubmitted: boolean - prop that shows submitted state of form
• isSubmitting: boolean - props that show is submitting in process
• updateForm: () => void - method for call form onChange callback (e.g. for saving values to redux)
• submitForm: () => void - method for submitting form, will call onSubmit callback
• resetForm: () => void - method for resetting form to initialValues

---
