Installation

Install the package using npm:

npm install @emacapt/widget-react

Usage

There are two ways to use the EmacaptWidget: with a server-side endpoint (recommended for security) or with direct API calls. You must choose one of these methods. Email field is mandatory and will be automatically added to the form.

Server-Side Usage (Recommended for Security)

Use @emacapt/widget-react with a Next.js API route:

  1. Create an API route (e.g., pages/api/submit-form.ts):
import type { NextApiRequest, NextApiResponse } from "next";

export default async function handler(
  req: NextApiRequest,
  res: NextApiResponse,
) {
  if (req.method !== "POST") {
    return res.status(405).json({ message: "Method Not Allowed" });
  }

  const formData = req.body;

  try {
    const headers = new Headers();

    headers.append('Content-Type', 'application/json');
    headers.append('X-Project-Api-Key', process.env.API_KEY ?? '');

    const response = await fetch('https://api.emacapt.com/clients', {
      method: 'POST',
      headers,
      body: JSON.stringify(formData)
    });

    if (!response.ok) {
      throw new Error("API request failed");
    }

    const data = await response.json();
    return res.status(200).json(data);
  } catch (error) {
    console.error("Error submitting form:", error);
    return res
      .status(500)
      .json({ error: "An error occurred while submitting the form" });
  }
}
  1. Use the widget in your React component:
import React from "react";
import { EmacaptWidget, createField, validations } from "@emacapt/widget-react";

const MyForm = () => {
  const fields = [
    // Note: You don't need to include an email field, it's automatically added
    createField({
      name: "name",
      label: "Full Name",
      type: "text",
      required: true,
    }),
    createField({
      name: "message",
      label: "Message",
      type: "text",
      required: false,
    }),
  ];

  const customTextOptions = {
    openFormButton: "Contact Us",
    submit: "Send Message",
    success: "Thank you for your message!",
  };

  const handleSuccess = (data) => {
    console.log("Form submitted successfully:", data);
  };

  const handleError = (error) => {
    console.error("Error submitting form:", error);
  };

  return (
    <div>
      <h1>My Contact Form</h1>
      <EmacaptWidget
        serverEndpoint="/api/submit-form"
        fields={fields}
        primaryColor="indigo"
        textOptions={customTextOptions}
        onSuccess={handleSuccess}
        onError={handleError}
      />
    </div>
  );
};

export default MyForm;

Client-Side Usage (Less Secure)

For scenarios where server-side processing is not possible, you can use the widget with direct API calls. However, this method is less secure as it exposes your API key to the client.

import React from "react";
import { EmacaptWidget } from "@emacapt/widget-react";

const MyForm = () => {
  // ... rest of the component logic

  return (
    <EmacaptWidget
      apiKey="your-api-key-here"
      apiUrl="https://api.emacapt.com/submit-form"
      primaryColor="indigo"
      textOptions={customTextOptions}
      onSuccess={handleSuccess}
      onError={handleError}
    />
  );
};

export default MyForm;

Configuration Options

Props

You must provide either serverEndpoint or both apiKey and apiUrl:

  • serverEndpoint (string, recommended): The endpoint for your server-side API route.
  • apiKey (string, less secure): Your API key for direct API calls.
  • apiUrl (string, less secure): The URL to submit the form data to.

Other props:

  • fields (Field[]): An array of field configurations. Note: An email field is automatically added and does not need to be included in this array.
  • primaryColor (string, optional): The primary color theme ('blue', 'indigo', 'green', or 'red'). Default is 'blue' or put your own color value as hex string, e.g "#0066ff".
  • textColor (string, optional): The color of the text in the form. Default is 'white'.
  • textOptions (Partial, optional): Customized text for various parts of the widget.
  • onSuccess (function): Callback function called when form submission is successful.
  • onError (function): Callback function called when an error occurs during form submission.

Field Configuration

Fields are typically configured using the createField helper function and preset validations. However, you can also manually create fields and provide custom validation functions if needed.

import { createField, validations } from "@emacapt/widget-react";

const fields = [
  // Note: You don't need to include an email field, it's automatically added
  createField({
    name: "name",
    label: "Full Name",
    type: "text",
    required: true,
  }),
  createField({
    name: "age",
    label: "Age",
    type: "number",
    required: true,
    validation: (value: number) => {
      return value >= 18 ? null : "You must be 18 or older";
    },
  }),
  createField({
    name: "preferences",
    label: "Preferences",
    type: "select",
    options: [
      { value: "option1", label: "Option 1" },
      { value: "option2", label: "Option 2" },
    ],
    required: false,
  }),
  // ... other fields
];

return (
  <EmacaptWidget
    apiKey="your-api-key-here"
    apiUrl="https://api.emacapt.com/submit-form"
    fields={fields} // put fields here
    textOptions={customTextOptions}
    onSuccess={handleSuccess}
    onError={handleError}
  />
);

Submission Data Structure

When the form is submitted, the data will be structured as follows:

{
  email: string,
  data: {
    [fieldName: string]: string | number | boolean
  }
}

The email field is automatically included at the top level, and all other fields are included in the data object.

Text Customization

Customize the widget's text by passing a textOptions object:

const customTextOptions = {
  openFormButton: "Contact Us",
  submit: "Send",
  submitting: "Sending...",
  success: "Thank you!",
  error: "Oops! Something went wrong.",
  requiredField: "This field is required",
  invalidEmail: "Please enter a valid email",
  selectPlaceholder: "Choose an option",
  modalTitle: "Get in Touch",
  modalSubheading: "We'd love to hear from you!",
  closeButtonAriaLabel: "Close form",
};

Styling

The widget uses Tailwind CSS for styling. The necessary styles are included in the package, so you don't need to import any additional CSS files.
