Mobx-React-Form Tutorial

Creating a detailed tutorial here might be challenging due to space constraints, but I can provide a general overview of how to get started with Mobx-react-form and where to find resources for learning more.

Getting Started:

  1. Installation: First, you need to install mobx-react-form along with its dependencies. You can do this via npm or yarn:

    npm install mobx mobx-react-form --save

    or

    yarn add mobx mobx-react-form
  2. Setting up MobX: If you haven’t already, you need to set up MobX in your project. This typically involves creating a MobX store and configuring it to manage your application’s state.

  3. Creating a Form: Start by creating a new form using mobx-react-form. You can define your form fields and validation rules using a simple schema syntax. For example:

    import { Form } from 'mobx-react-form';
    
    const fields = {
      name: '',
      age: 0,
    };
    
    const rules = {
      name: 'required|string',
      age: 'required|numeric',
    };
    
    const form = new Form({ fields }, { plugins: { dvr: { package: validatorjs } }, rules });
  4. Rendering the Form: Once your form is created, you can render it in your React components using MobX’s observer higher-order component. This will ensure that your form updates reactively in response to changes in its state.

    import { observer } from 'mobx-react';
    
    const MyForm = observer(() => (
      <form onSubmit={form.onSubmit}>
        <input {...form.$('name').bind()} />
        <p>{form.$('name').error}</p>
    
        <input {...form.$('age').bind()} />
        <p>{form.$('age').error}</p>
    
        <button type="submit">Submit</button>
      </form>
    ));
  5. Handling Form Submission: Finally, you need to handle form submission by calling the onSubmit method of your form instance. You can then access the form values and perform any necessary actions, such as sending data to a server.

    form.onSubmit((form) => {
      console.log('Form submitted:', form.values());
    });
