create-T3-app with extra tools/config out of the box

create-t3-app is one of the fastest and easiest way to scaffold fullstack app. This version make it even faster for my case (and maybe yours). 🏃💨

Step to follow:

1. pnpm install
2. Rename next-env to next-env.d.ts
3. Rename .env.example to .env and fill the value 3.1 Local database 3.2 Google Oauth
4. Deploy 🎉 🚀 4.1 Planetscale 4.2 Vercel

Linting & Formatting 🧹

better code ¹ without the frustration of config.

Install prettier with the config & plugin for eslint & tailwind

pnpm i -D prettier eslint-config-prettier eslint-plugin-prettier prettier-plugin-tailwindcss

  Confuse about plugin vs config? Read this and this.

  Why don't we use stylelint also?
  Tailwind is more than enough. Use arbitrary value & custom style.

Here is my experience:
I make component animation on css and realize that you can move it to tailwind custom style. I use scss on svg animation and realize css is not for this kind of job. You will screw up really fast (sarah drasner said). I move using animation library instead (more below).

Add prettier config file prettier.config.cjs

module.exports = {
  trailingComma: 'es5',
  useTabs: true,
  tabWidth: 2,
  semi: false,
  singleQuote: true,
  bracketSpacing: false,
  jsxSingleQuote: true,
  plugins: [require('prettier-plugin-tailwindcss')],
  tailwindConfig: './tailwind.config.cjs',
}

Extend eslint config .eslint.json

{
- "plugins": ["@typescript-eslint"],
+ "plugins": ["@typescript-eslint", "prettier"],
  "extends": [
    "next/core-web-vitals",
    "plugin:@typescript-eslint/recommended",
+   "prettier"
  ],
+ "rules": {
+   "prettier/prettier": "warn"
+ }
}

You can use prettier only on formatting or also give linting error/ warning. For my chase warn me.

Add more plugin if you need it

I personally love unicorn plugin.

Lint & format all of your file

pnpm prettier --write .

pnpm eslint .

Git hooks ⛓️

better ¹ and more exciting git experience. It can slow you down and it is. Here is why. Move pre-commit & pre-push on CI (vercel status check)

🧹 Pre-commit

  You don't need it. But if your need it, add it by yourself.

Add husky to the project

pnpm dlx husky-init && pnpm i

Install lint-staged

pnpm i -D lint-staged

Add config file .lintstagedrc

{
  "*.{js,jsx,cjs,ts,tsx}": "eslint --fix",
  "*.{md,json}": "prettier --write"
}

Run lint-staged on pre-commit hook

#!/usr/bin/env sh
. "$(dirname -- "$0")/_/husky.sh"

- npm test
+ pnpm lint-staged

If the log message doesn't show correctly, see this issue

📨 Commit message

  Give clear message by following the convention

Install commitlint

pnpm install -D @commitlint/cli @commitlint/config-conventional

Add config file
commitlint.config.cjs

module.exports = {
  extends: ['@commitlint/config-conventional'],
}

Add to commit-message hook

pnpm dlx husky add .husky/commit-msg "pnpm commitlint --edit \"\$1\""

Test by making a commit

git commit -m "foo: bar"

🤯 Commit emoji

  Who don't like emoji??

Install gitmoji

pnpm i -g gitmoji-cli

Install gitmoji config for commitlint

pnpm i -D commitlint-config-gitmoji

Update commitlint config file

module.exports = {
- extends: ['@commitlint/config-conventional'],
+ extends: ['gitmoji'],
+ rules: {
+   'header-max-length': [0, 'always', 100],
+   'scope-case': [0, 'always', 'pascal-case'],
+ },
}

Commit using gitmoji

gitmoji -c

🏗️ Pre-push

  Clean doesn't mean it's not break

pnpm dlx husky add .husky/pre-push "pnpm build"

Hosting provider usually charge money if you exceed the build time limit. It can save you some time.

Optimization 📈

Don't bring unnecessary thing in your baggage

📦 Bundle Analyzer

  Consider package bundle size before add it to your arsenal.

Install bundle analyzer

pnpm -i -D @next/bundle-analyzer

Edit next.config.cjs

+ import bundleAnalyzer from '@next/bundle-analyzer'

+ const withBundleAnalyzer = bundleAnalyzer({
+   enabled: process.env.ANALYZE === 'true',
+ })

function defineNextConfig(config) {
- return config
+ return withBundleAnalyzer(config)
}

Add bundle analyzer build script

+ "build-stats": "ANALYZE=true pnpm build"

Run build with bundle analyzer

pnpm build-stats

You can also check using bundle size using bundlephobia.

🧰 CSS

  Optimize tailwind on production

Minify CSS using cssnano

pnpm -i -D cssnano

Edit postcss.config.cjs

module.exports = {
  plugins: {
    tailwindcss: {},
    autoprefixer: {},
+   ...(process.env.NODE_ENV === 'production' ? {cssnano: {}} : {}),
  },
}

Going Live 🚀

Why wait so long to go to the moon?

🪐 MySQL on PlanetScale

  Sit with ease in case your app suddenly become a startup. Watch this interview

I use both local database & PlanetScale branch database for development. Depend on your need.
For local I use prisma migrate dev
For remote I use prima db push
Read this for the differences.

Local MySQL server

For MySQL installation follow guide.

Set database url on .env
DATABASE_URL=mysql://user:password@localhost:3306/database_name

Migrate local database (better wait after planet scale setup)

pnpm prisma migrate dev

PlanetScale setup

Ignore prisma migration file in .gitignore
/prisma/migrations/*

Follow this instruction and you are good to go.

Code mods:
prisma.schema

datasource db {
  url                  = env("DATABASE_URL")
+ relationMode = "prisma"

model Account {
...
+ @@index([userId])
}

model Session {
...
+ @@index([userId])
}

Replace your DATABASE_URL on .env with url that you get from PlanetScale

Add SSL certificate to database url to enable secure connection. For SSL certificate location, see this docs. ?ssl={"rejectUnauthorized":true}&sslcert=/etc/pki/tls/certs/ca-bundle.crt

To establish secure connection from local server with branch database, add env below. MYSQL_ATTR_SSL_CA=/etc/ssl/certs/ca-certificates.crt

🔎 Google OAuth

  Who doesn't have google account?

Create new project

Configure OAuth consent screen

Your vercel preview branch domain will not be allowed to access the OAuth consent screen except your add it. So my workaround would be to create a development branch, add a new domain (for preview) on vercel and attach it to the development branch. On the authorized domains section, add both of your domains.

your-domain.vercel.app
your-preview-domain.vercel.app

Create credentials

Add "Authorized JavaScript origins" with base url

http://localhost:3000
https://your-domain.vercel.app
https://your-preview-domain.vercel.app

Add "Authorized redirect URIs" with callback url

http://localhost:3000/api/auth/callback/google
https://your-domain.vercel.app/api/auth/callback/google
https://your-preview-domain.vercel.app/api/auth/callback/google

Add google credential to .env

+ GOOGLE_CLIENT_ID = 'Your Client ID'
+ GOOGLE_CLIENT_SECRET = 'Your Client Secret'

Add google env to schema.mjs

export const serverSchema = z.object({
  ...
+ GOOGLE_CLIENT_ID: z.string(),
+ GOOGLE_CLIENT_SECRET: z.string(),
})

Add Google provider & enable jwt on [..nextauth].ts

+ import GoogleProvider from 'next-auth/providers/google'

  callbacks: {
    session({session, user}) {
      ...
    },
+   async jwt({token}) {
+     return token
+   },
  },

  providers: [
+   GoogleProvider({
+     clientId: env.GOOGLE_CLIENT_ID,
+     clientSecret: env.GOOGLE_CLIENT_SECRET,
+   }),
    ...
  ],

Enable jwt callback (required)

callbacks: {
  session({session, user}) {
    ...
  },
+ async jwt({token}) {
+   return token
+ },
},

🔺 Vercel

  Except you like to complicate things

Add the env for each environment & deploy

Add your live url as next auth url on .env

+ NEXTAUTH_URL=https://your-domain.vercel.app

Other helpful things 🪛

Trivially important

📄 NextJS custom Document

Create custom document _document.tsx on pages directory

import {Html, Head, Main, NextScript} from 'next/document'

export default function Document() {
  return (
    <Html>
      <Head></Head>
      <body>
        <Main />
        <NextScript />
      </body>
    </Html>
  )
}

🅵 Fonts

  There are a lot of curated font pairing ready to pick.

Pick font pairing from two of the most useful collection from heyreliable.com and pagecloud.com. You can also filter by the style that match your app.

💡 Steal font combo from your favorite website.

Go to google font and search those fonts.

Select the specimen that you will use. Remember about performance! I recommend pick three font weight and the italic version of each weight.

Add the font link inside <Head> component on _document.tsx

  <Head>
+   <link rel="preconnect" href="https://fonts.googleapis.com" />
+   <link rel="preconnect" href="https://fonts.gstatic.com" crossorigin="" />
+   <link
+     href="https://fonts.googleapis.com/css2?family=Hind:wght@400;600&family=Montserrat:ital,wght@0,400;0,600;0,800;1,400;1,600;1,800&display=swap"
+     rel="stylesheet"
+   />
  </Head>

Extend tailwind config with the font family

  theme: {
    extend: {
      fontFamily: {
+       heading: ['Montserrat', 'sans-serif'],
+       body: ['Hind', 'sans-serif'],
      },
    },
  },

You can apply it directly to the tag if needed by changing styles/global.css

@layer base {
  h1,
  h2,
  h3,
  h4,
  h5,
  h6 {
    @apply font-heading;
  }

  p {
    @apply font-body;
  }
}

⭐ Favicon

  Just get it correctly.

Prepare your svg icon

Go to realfavicongenerator.net

Adjust & generate favicon

Download & put on public directory

Copy generated link to head on _document.tsx

  <Head>
  ...
+   <link rel="apple-touch-icon" sizes="180x180" href="/apple-touch-icon.png" />
+   <link rel="icon" type="image/png" sizes="32x32" href="/favicon-32x32.png" />
+   <link rel="icon" type="image/png" sizes="16x16" href="/favicon-16x16.png" />
+   <link rel="manifest" href="/site.webmanifest" />
+   <link rel="mask-icon" href="/safari-pinned-tab.svg" color="#5bbad5" />
+   <meta name="msapplication-TileColor" content="#2d89ef" />
+   <meta name="theme-color" content="#ffffff" />
  <Head />

🌟 Animation

  Steal user attention & help them navigate.

These css animation collection very useful to make your website stand out

• animate.css
• magic
• hover

Auto animate also really helpful for element transition.

For svg animation use GSAP. Sarah Drasner and other pro recommend it because it's the most mature and reliable library.

💨 Tailwind config

  Small details fixes.

Additional default override. For what? read this

@layer base {
  html {
    -webkit-tap-highlight-color: transparent;
  }
}

@layer utilities {
  .pb-safe {
    padding-bottom: env(safe-area-inset-bottom);
  }
}

👓 SASS

  Managing keyframe will ruin your entire day.

You will mess up very quickly if you don't use variables for handling keyframe. But we don't want JS yet for this simple animation.

• Attention seeker & Transition > SASS
• Interaction & complex SVG > JS library

Install sass

pnpm i -D sass

Add script to watch & debug sass

"scripts": {
  ...
+ "sass-watch": "sass --watch src/styles:css"
},

Ignore output file

+ # sass watch output
+ /css

Add typescript-plugin-css-modules for autocompletion

pnpm i -D typescript-plugin-css-modules

Update tsconfig

"compilerOptions": {
+ "plugins": [{ "name": "typescript-plugin-css-modules" }]
}

Add to vscode config

+ "typescript.tsserver.pluginPaths": ["typescript-plugin-css-modules"]

🛣 Path Aliases

  Stop playing guess game while importing module

Add base path & path aliases on tsconfig.json

+ "baseUrl": "src",
+ "paths": {
+   "@components/*": ["components/*"],
+   "@api/*": ["pages/api/*"],
+   "@pages/*": ["pages/*"],
+   "@animation/*": ["styles/animation/*"],
+   "@styles/*": ["styles/*"],
+   "@utils/*": ["utils/*"],
+   "@server/*": ["server/*"],
+   "@images/*": ["../public/images/*"]
+ },

🗡️ Bleeding edge tech

Cool tech should not make you bleeding

These is only for exploration & discussion.

ORM Replacement

Kysely provide end-to-end type-safety but also edge-first approach to ORM replacement

DB Replacement

Legacy databaase is awesome. PlanetScale is super awesome.
