React : window.scrollTo or move page to a position

 

Certainly, if you want to use `window.scrollTo` or equivalent methods to scroll the page, here are some examples:

 

1. **Using `window.scrollTo` with Coordinates**:

 

```tsx

const scrollToPosition = (yPosition: number) => {

    window.scrollTo({ top: yPosition, behavior: 'smooth' });

};

// Example usage

scrollToPosition(500); // Scroll to y position 500

```

In this example, `window.scrollTo` is used to scroll to a specific y-position on the page. The `behavior: 'smooth'` option provides smooth scrolling.

2. **Using Element's `scrollIntoView` Method**:

```tsx

const scrollToElement = (elementId: string) => {

    const element = document.getElementById(elementId);

    if (element) {

        element.scrollIntoView({ behavior: 'smooth' });

    }

};

// Example usage

scrollToElement('myTargetElement'); // Scroll to element with id "myTargetElement"

```

In this example, the `scrollIntoView` method is used on an HTML element with a specified ID. The element will be scrolled into view with smooth scrolling.

 

3. **Using `scrollTo` or `scrollBy` on Specific Element**:

 

```tsx

const scrollToElement = (elementId: string, yOffset: number = 0) => {

    const element = document.getElementById(elementId);

    if (element) {

        const yPosition = element.getBoundingClientRect().top + window.pageYOffset + yOffset;

        window.scrollTo({ top: yPosition, behavior: 'smooth' });

    }

};

// Example usage

scrollToElement('myTargetElement', -100); // Scroll to element with id "myTargetElement" with a yOffset of -100 pixels

```

In this example, `getBoundingClientRect` is used to calculate the y-position of an element relative to the viewport. You can adjust the yOffset to fine-tune the scrolling position.

Remember that smooth scrolling behavior might not work in all browsers or under all circumstances. It's generally supported in modern browsers. If smooth scrolling doesn't work as expected, you can use the default behavior by omitting the `behavior` option or replacing `'smooth'` with `'auto'`.

yup vs formik in React TS

 Both "yup" and "Formik" are popular libraries in the React ecosystem, especially when it comes to handling forms and form validation. Let's take a look at what each library does and how they compare in the context of React with TypeScript.

1. **yup:**

   "yup" is a schema validation library that focuses on defining and validating data schemas, often used for form input validation. It provides a simple and declarative way to define validation rules for your data structures. "yup" is not specifically designed for form management but rather for validating data before it gets submitted to APIs or stored in a database.

   **Pros of yup:**

   - Declarative schema validation.

   - Works well with form validation scenarios.

   - Provides powerful validation and transformation capabilities.

   - Schema can be reused across different parts of your application.

   **Cons of yup:**

   - It's primarily focused on validation and doesn't handle form state management.

   - Doesn't offer built-in form handling features like handling form submissions, tracking form values, etc.

2. **Formik:**

   "Formik" is a library that provides a set of tools and utilities for handling forms in React. It helps manage form state, form submission, and validation. While Formik itself doesn't provide schema validation, it can work seamlessly with validation libraries like "yup" to achieve comprehensive form handling.

   **Pros of Formik:**

   - Offers a complete solution for form management, including state, submission, and validation.

   - Integrates well with various validation libraries, including "yup."

   - Provides a way to manage form fields and their values efficiently.

   - Supports handling complex form validation scenarios.

   **Cons of Formik:**

   - Might have a bit of a learning curve for complex use cases.

   - Formik's API and concepts might seem overwhelming for simpler forms.

**Using them together:**

A common approach is to use "Formik" for managing form state and submission while using "yup" for schema validation. This combination leverages the strengths of both libraries. Formik provides an excellent framework for handling form state and user interactions, while "yup" takes care of data validation based on the defined schemas.

In a TypeScript React application, you can benefit from TypeScript's type checking to ensure that your form state and validation schemas align correctly.

In summary, if you're looking for a comprehensive solution for handling forms, especially in a TypeScript environment, using "Formik" for form management and combining it with "yup" for schema validation is a strong approach.
