A Glimpse into the Code

Let’s dissect the key elements of the Sign-In page code:

Form Validation with Formik and Yup

The useFormik hook from Formik and Yup are employed for form state management and validation.

Stylish UI with Material-UI

Material-UI components such as TextFieldButtonTypography, and Alert are used to create an aesthetically pleasing and user-friendly sign-in form.

Handling Form Submission with Axios

The onSubmit function of the Formik hook is responsible for handling form submissions. In this case, Axios is utilized to make a POST request to a specified API endpoint (/api/Signin).

User Interface Split with Next.js Image Component

The Sign-In page is visually split into two sections, with the left side showcasing the service logo and a welcome message. The right side features the sign-in form.

Customizing the Sign-In Page

This Sign-In page is highly customizable for various projects. You can tweak the styling, add branding elements, or integrate it seamlessly into your existing Next.js application.

// pages/index.js
import Head from "next/head";
import NextLink from "next/link";
import { useRouter } from "next/router";
import { useFormik } from "formik";
import * as Yup from "yup";
import {
  Alert,
  Box,
  Button,
  Link,
  Stack,
  TextField,
  Typography,
  Grid,
} from "@mui/material";
import axios from "axios";
import Image from "next/image";

const Index = () => {
  const router = useRouter();

  const validationSchema = Yup.object({
    username: Yup.string().required("Username is required"),
    password: Yup.string().required("Password is required"),
  });

  const formik = useFormik({
    initialValues: {
      username: "",
      password: "",
    },
    validationSchema: validationSchema,
    onSubmit: async (values) => {
      let payload = {
        username: values.username,
        password: values.password,
      };
      try {
        const response = await axios.post(`/api/Signin`, payload);
        if (response.status === 200) {
          router.push("/dashboard");
          formik.resetForm();
        }
      } catch (error) {
        console.log("Errors", error);
      }
    },
  });
