mobx-zod-form-store

A MobX-based form store with Zod validation, featuring a dynamic Form component for React applications.

Description

mobx-zod-form-store is a comprehensive utility package designed to streamline the process of creating, managing, and validating forms in React applications. It utilizes MobX for state management and Zod for robust schema validation. This package also includes a dynamic Form component, making form creation more declarative and less error-prone.

Installation

To install the package, use npm:

npm i mobx-zod-form-store

Usage

Basic FormStore Usage

Here's a basic example of how to use the FormStore:

import FormStore from 'mobx-form-store';
import { z } from 'zod';

// Define your schema
const formSchema = z.object({
  name: z.string().min(1, 'Name is required'),
  bio: z.string().min(1, 'Bio is required'),
});

// Create a store
const formStore = new FormStore({ name: '', bio: '' }, formSchema);

// Update fields and validate
formStore.setField('name', 'John Doe');
formStore.validate();

Using useFormStore Hook

You can also use the useFormStore hook for managing form state in functional components:

import React from 'react';
import useFormStore from 'path-to-useFormStore';
import { z } from 'zod';

// Define your form schema
const formSchema = z.object({
  name: z.string().min(1, 'Name is required'),
  email: z.string().email('Invalid email address'),
});

const MyForm = () => {
  const { formStore, handleChange, handleSubmit } = useFormStore({
    initialFields: { name: '', email: '' },
    validationSchema: formSchema,
    onSubmit: async (fields) => {
      // Handle form submission
      console.log('Form Data:', fields);
    },
  });

  return (
    <form onSubmit={handleSubmit}>
      <div>
        <label htmlFor="name">Name</label>
        <input
          id="name"
          type="text"
          value={formStore.fields.name}
          onChange={(e) => handleChange('name', e.target.value)}
        />
        {formStore.errors.name && <span>{formStore.errors.name}</span>}
      </div>

      <div>
        <label htmlFor="email">Email</label>
        <input
          id="email"
          type="email"
          value={formStore.fields.email}
          onChange={(e) => handleChange('email', e.target.value)}
        />
        {formStore.errors.email && <span>{formStore.errors.email}</span>}
      </div>

      <button type="submit">Submit</button>
    </form>
  );
};

export default MyForm;

Dynamic Form Component

The Form component allows you to create forms dynamically based on a configuration array. This array defines the fields, their types, placeholders, and other properties.

Form Field Types The package supports the following field types:

  • text: For text input.
  • number: For numeric input.
  • textarea: For multiline text input.
  • multiselect: For a multi-select input.
  • multiitem: For a group of related inputs.
  • imageupload: For uploading images.

Example of Using the Form Component

import React from 'react';
import Form, { FieldType } from 'path-to-Form';
import { z } from 'zod';

// Form fields configuration
const fieldsConfig = [
  { name: 'name', type: FieldType.Text, placeholder: 'Name', className: 'mb-4 p-2 border rounded' },
  { name: 'age', type: FieldType.Number, placeholder: 'Age', className: 'mb-4 p-2 border rounded' },
  // More fields with Tailwind classes...
];

// Form validation schema
const formSchema = z.object({
  name: z.string().min(1, 'Name is required'),
  age: z.number().min(0, 'Age must be a positive number'),
  // Validation for other fields...
});

const MyDynamicForm = () => {
  const handleSubmit = async (fields) => {
    // Handle form submission
    console.log('Form Data:', fields);
  };

  return (
    <Form
      fieldsConfig={fieldsConfig}
      initialFields={{ name: '', age: 0 }}
      validationSchema={formSchema}
      onSubmit={handleSubmit}
      className={'border p-2'}
    />
  );
};

export default MyDynamicForm;

  • Use the Component: Import and use the ImageUpload component in your forms.

import React from 'react';
import { useFormStore, ImageUpload } from 'mobx-zod-form-store';
import { z } from 'zod';

const formSchema = z.object({
  imageUri: z.array(z.string()),
});

const MyForm = () => {
  const { formStore, handleSubmit } = useFormStore({
    initialFields: { imageUri: [] },
    validationSchema: formSchema,
    onSubmit: (fields) => {
      console.log('Form Data:', fields);
    },
  });

  return (
    <form onSubmit={handleSubmit}>
      <ImageUpload name="imageUri" formStore={formStore} />
      <button type="submit">Submit</button>
