Crafting Scalable Architectures: Project Structure Insights

This section provides a high-level overview of how the Next JS TypeScript Redux boilerplate codebase is structured, including the key folders, configuration files, and development tools. Understanding the project anatomy is crucial for effectively building upon the boilerplate.

Navigating the File System of Next.js Boilerplate 2023 GitHub Repositories

The Next JS TypeScript Redux boilerplate follows common conventions for organizing a Next.js application.

Some key folders and files:

• /pages - Contains page components that define the application routes. For example, pages/index.tsx renders the homepage.
• /components - Houses all reusable React components.
• /hooks - Custom hooks like useAuth.ts for handling authentication logic.
• /store - Redux folders like slices and reducers for state management.
• /styles - Global styles and theme files using Tailwind CSS.
• /utils - Helper methods for things like API calls.

The main configuration files are:

• next.config.js - Next.js build settings, asset prefixes, redirects etc.
• tsconfig.json - TypeScript compiler options.
• .eslintrc - ESLint settings for code linting.
• jest.config.js - Jest test framework config.

This structure separates concerns into organized units while keeping a flat architecture for simplicity.

State Management with Redux: A Strategic Approach

Redux helps manage application state in a predictable way across components. The Next JS TypeScript Redux boilerplate has Redux Toolkit integrated with React/Next.js.

Some key Redux folders and files:

• store.ts - The Redux store creation and configuration.
• slices/ - State slices containing actions, reducers and action creators for each domain like auth.slice.ts.
• reducers/ - Root reducer combining all state slices.

Here is a code snippet showing a Redux slice:

// auth.slice.ts

import { createSlice } from '@reduxjs/toolkit';

export const authSlice = createSlice({
  name: 'auth',
  initialState: { isLoggedIn: false },
  reducers: {
    login: state => {
      state.isLoggedIn = true; 
    },
    logout: state => { 
      state.isLoggedIn = false;
    }
  }
})

export const { login, logout } = authSlice.actions;
export default authSlice.reducer;

This structure promotes separation of state logic while keeping related code co-located. It provides a scalable foundation for complex applications. The boilerplate handles integrating Redux with Next.js for a smooth developer experience.

Building with Best Practices: Core Functionality Using Redux

This section walks through building core app functionality using the boilerplate as a guide for developers to follow along.

Seamless Data Handling in Next.js Apps

The Next.js framework provides two key data fetching methods - getStaticProps and getServerSideProps - to handle data population on page loads. Here is an example using getServerSideProps in the boilerplate:

export const getServerSideProps = wrapper.getServerSideProps(
  (store) => async () => {
    try {
      await store.dispatch(getPosts());

      return {
        props: {},
      };
    } catch (err) {
      return {
        props: {
          error: err.message,
        },
      };
    }
  }
);

This allows handling async data, then passing props to the page component. The Redux store is also available via store.dispatch.

To manage loading and error UI states, the boilerplate provides reusable components:

<LoadingState />

<ErrorState message={error} /> 

These ensure a smooth user experience when fetching data on page navigation.

Securing User Access: Authentication Flow Mastery

The boilerplate incorporates JSON Web Token (JWT) authentication for secure user access. Signup and login works as:

// Signup request

const response = await axios.post("/api/auth/signup", {
  name,
  email,
  password
});

// Receive JWT on success
const { token } = response.data;

// Login request

const { token } = await axios.post("/api/auth/login", {
  email, 
  password
});

The JWT can then be stored locally or in a cookie for authorized API requests.

Protected routes are also configured using the isAuthorized Higher Order Component (HOC):

function PrivatePage() {
  return <p>Private page content</p>;
}

// Wrap with isAuthorized HOC
export default isAuthorized(PrivatePage);

This checks the JWT before allowing access to the page.

Ensuring Input Integrity: Form Validation Techniques

For bulletproof forms, the boilerplate includes client and server-side validation using Yup.

Example validating a signup form:

// Validation schema
const schema = yup.object().shape({
  name: yup.string().required(),
  email: yup.string().email().required(),
  password: yup
    .string()
    .min(8)
    .max(100)
    .required(),
});

// Validate on submit
const onSubmit = async (values) => {
  try { 
    await schema.validate(values, { abortEarly: false });
    
    // Submit data to API
    
  } catch (err) {
    // Yup errors
  }
}

The same validation schema can be reused on the API route:

// Reuse Yup schema

const { error } = schema.validate(req.body); 
if (error) {
  // Return error response
}

// Data is valid

This ensures consistency between client and server-side validation logic.

The boilerplate simplifies form building while keeping input secure across the stack.

Embracing Advanced Techniques for Sophisticated Applications

This section covers more advanced topics for taking apps built with this boilerplate to the next level.

Ensuring Quality with Jest: A Testing Roadmap

Jest is a popular JavaScript testing framework that comes preconfigured in Next.js. Writing tests ensures code quality and prevents regressions. Here is a guide for setting up and writing effective tests with Jest:

First install React Testing Library:

npm install --save-dev @testing-library/react

Unit Testing Components

Unit test isolated React components with helpers from React Testing Library:

import { render, screen } from '@testing-library/react'
import UserInfo from '../components/UserInfo'

describe('UserInfo', () => {
  it('renders user data', () => {
    render(<UserInfo user={{ name: 'John' }} />)
    
    const userName = screen.getByText(/John/i)
    
    expect(userName).toBeInTheDocument()
  })
})

Mock any data passed via props to test components in isolation.

Integration Testing Pages

Render full Next.js pages to integration test complete features:

import { render, screen } from '../testUtils'
import Homepage from '../pages/index'

describe('Homepage', () => {
  it('renders homepage', () => {
     render(<Homepage />)
    
     expect(screen.getByText(/welcome/i)).toBeInTheDocument()
  })
})

Use a custom test utils file to handle Next.js' Server Side Rendering during tests.

Testing Utility Functions

Test standalone utility modules:

import { formatDate } from '../utils/formatDate'

describe('formatDate', () => {
  it('returns formatted date string', () => {
    const formatted = formatDate(new Date(2020, 1, 1))
    
    expect(formatted).toBe('02/01/2020')
  })
}) 

Aim for at least 80% test coverage across the app.

Enhancing Visibility: SEO with Server-side Rendering

Next.js applications have SEO advantages out of the box with built-in server side rendering. Here are some tips for optimizing SEO:

Dynamic Routes

For dynamic pages, pre-render data at build time so search engine crawlers can index the content. Under pages, create a file called [id].js that exports a getStaticProps function:

export async function getStaticPaths() {
  // Return list of possible ids
}

export async function getStaticProps({ params }) {
  // Fetch data for id
  return {
    props: { data } 
  }
}

export default function Page({ data }) {
  // Display page
}

Now each dynamic page can be pre-rendered with data for SEO.

Head Tags

Populate all important `` meta tags in `pages/_document.js` for consistent SEO across the site:

export default class Document {
  render() {
    return (
      <Html>
        <Head>
          <meta name="description" content="Site description for SEO"/>
          <meta property="og:title" content="Page title for social media"/>
          <link rel="canonical" href="https://www.example.com/"/> 
        </Head>
        <body>
          <Main />
          <NextScript />
        </body>
      </Html>
    )
  }
}

This ensures proper search indexing and social media snippets.

Image Optimization

Use the next/image component for automatic image optimization.

With these practices, Next.js apps can match and even exceed the SEO of traditional server rendered websites.

Elevating the User Experience: PWA with Next.js Tailwind Boilerplate

The next-pwa plugin configures Next.js apps as PWAs with just a few steps:

1. Install:

npm install next-pwa

2. Add plugin config to next.config.js:

const withPWA = require('next-pwa')

module.exports = withPWA({
  pwa: {
    dest: 'public',
    register: true,
    skipWaiting: true,   
  }
})

3. Use React hooks in pages to handle service worker lifecycle:

import { useEffect } from 'react'  
import { useRouter } from 'next/router'
import * as Fathom from 'fathom-client'

export default function Home() {

  const router = useRouter()
  
  useEffect(() => {
    const handleRouteChange = url => {
      Fathom.trackPageview()
    }
    router.events.on('routeChangeComplete', handleRouteChange)
    return () => {
      router.events.off('routeChangeComplete', handleRouteChange)
    }
  }, [router.events])  

  return <p>Welcome Home!</p>
}

That's it! The app now has offline support, an installable icon on devices, and loads fast even on slow networks.
