## Introduction
Well, many of you already know that while making a project we have to deal with many things like creating styles and layouts, form handling and validations, data fetching, creating functionalities, state management, etc. handling these things manually could be cumbersome. Instead, we are going to use libraries to handle these things for us.

<a id="tailwind-css"></a>
## Tailwind CSS
Let's start with the css, writing css could be messy with larger projects with lots of files, different styles, overriding classes, resetting css, utilities and all. It could take so much time to just setup the css stylesheets for the project. Tailwind is your savior for this problem, It utility-first CSS framework packed with classes like flex, grid, text-center, mt-10, etc that can be composed to build any design, directly in your markup. It's fast, flexible, and reliable — with zero-runtime.

[Documentation](https://tailwindcss.com/docs/installation)

### Example
```html
<div class="mx-auto max-w-sm bg-gray-100 mt-20">
  <div class="rounded-lg bg-slate-900 py-3 text-slate-100">
    <h2 class="text-center font-sans text-2xl md:text-3xl lg:text-4xl">Tailwind Card</h2>
  </div>
  <div class="bg-slate-00 text-balance p-5 font-sans text-base text-slate-900 md:text-lg">Tailwind is your savior for this problem, It utility-first CSS framework packed with classes like flex, grid, text-center, mt-10, etc that can be composed to build any design, directly in your markup.

```

## React hook form and Zod
* React hook form is a form handling library which is Performant, flexible and extensible with easy-to-use validation.
* Zod is a validation library which has many inbuilt methods to validate your input data without have to worry about writing logics manually
* @hookform/resolvers is a resolver library for react hook form, basically it helps in binding zod validations to react hook form inputs.

### Documentations
[React hook form](https://react-hook-form.com/)
[Zod](https://zod.dev/)
[@hookform/resolvers](https://www.npmjs.com/package/@hookform/resolvers)

### Example
```js
"use client";
import React from "react";
import { FieldValues, useForm } from "react-hook-form";
import { zodResolver } from "@hookform/resolvers/zod";
import * as z from "zod";

// NEXT UI Components
import { Modal, ModalContent, ModalHeader, ModalBody, ModalFooter, useDisclosure } from "@nextui-org/modal";
import { Button } from "@nextui-org/button";

const schema = z.object({
  name: z.string().min(1, { message: "Name is required" }),
  age: z
    .number({
      invalid_type_error: "Age must be a number",
    })
    .positive({ message: "Age must be positive" })
    .gt(18, { message: "Age should be greater than 18" }),
});

const Form = () => {
  const {
    register,
    handleSubmit,
    reset,
    watch,
    formState: { errors, isSubmitSuccessful },
  } = useForm({
    mode: "all",
    resolver: zodResolver(schema),
  });

  const onSubmit = (data: FieldValues) => {
    console.log(data);
    if (isSubmitSuccessful) {
      onOpen();
    }
  };

  const name = watch("name");

  // NEXT UI MODAL STATES
  const { isOpen, onOpen, onOpenChange } = useDisclosure();
  return (

<a id="zustand"></a>
## Zustand
It is basically a state management library just like redux but more light weight, flexible, simple and fasy.

[Documentation](https://github.com/pmndrs/zustand)

### Example
```ts
// store.ts
import { create } from "zustand";
import { persist, createJSONStorage } from "zustand/middleware";

// Define the state and action types
interface State {
  loggedIn: boolean;
  setLoggedIn: (loggedIn: boolean) => void;
}

// Create the Zustand store with type definitions and persistence
export const useStore = create<State>()(
  persist(
    (set) => ({
      loggedIn: false, // use false for boolean
      setLoggedIn: (loggedIn: boolean) => set({ loggedIn }),
    }),
    {
      name: "food-storage", // name of the item in the storage (must be unique)
      storage: createJSONStorage(() => sessionStorage), // (optional) by default, 'localStorage' is used
    },
  ),
);
```
```ts
// App.tsx
"use client";
import { useStore } from "@/store/useStore";
import React from "react";

const Zustand = () => {
  const loggedIn = useStore((state) => state.loggedIn);
  const setLoggedIn = useStore((state) => state.setLoggedIn);

  return (
    <div className="bg-gray-900 text-white min-h-[calc(100vh-64px)] p-8">
      <section className="flex flex-col items-center gap-10">
        <div className="flex items-center gap-6">
          <h3>User - {loggedIn ? "Logged In" : "Logged Out"}</h3>
          <button
            className={`px-4 py-2 inline-block rounded-lg text-white ${loggedIn ? "bg-red-500" : "bg-green-500"}`}
            onClick={() => setLoggedIn(!loggedIn)}
          >
            {loggedIn ? "Logout" : "Login"}
          </button>
        </div>
        <p className="text-lg font-sans mb-4">Login and refresh the page, the state will persist</p>
      </section>
    </div>
  );
};

export default Zustand;
```

<a id="prettier-esling"></a>
## Prettier Eslint
Prettier is a code formatting tool which helps in detecting issues related to formatting and also helps in resolving the formatting automatically while eslint is used to find linting errors like only allow single or double quotes, 100 characters per lines, variable defined but not used, etc, using eslint fix scripts, we could automatically fix these type of errors.
