Multipage Vite Vanilla JavaScript

Source Code: https://github.com/mochamadboval/multipage-vite-vanilla-js

Main Configuration

Create a Vite Vanilla JavaScript project.

npm create vite@latest multipage-vite-vanilla-js -- --template vanilla

cd multipage-vite-vanilla-js
npm i

Customize the project folder structure as follows.

|- node_modules/
|- src/
   |- assets/
      |- img/
         |- javascript.svg
      |- js/
         |- counter.js
   |- public/
      |- vite.svg
   |- index.html
   |- main.js
   |- style.css
|- .gitignore
|- package-lock.json
|- package.json

Since the index.html is no longer in the main project folder, the npm run dev cannot be executed. Therefore, create a vite.config.js file and set the new root path to the src folder. This only applies when the npm run dev and npm run build commands are executed.

// vite.config.js

export default {
  root: "./src",
};

Make some adjustments as follows and move the CSS import method to HTML.

// ./src/main.js

import { setupCounter } from "./assets/js/counter";

import viteLogo from "/vite.svg";
import javascriptLogo from "./assets/img/javascript.svg";

document.querySelector("#app").innerHTML = `
  <div>
    ...
    ...
    <a href="/about">About</a> |
    <a href="/blog/article">Article</a>
  </div>
`;

setupCounter(document.querySelector("#counter"));

<!-- ./src/index.html -->

  <title>Vite App</title>
  <link rel="stylesheet" href="/style.css">

Now we can execute npm run dev command. However, when running npm run build the dist folder will be created in the src folder. To move it out of that folder add the following configuration.

// vite.config.js

export default {
  root: "./src",
  build: {
    outDir: "../dist",
    emptyOutDir: true,
  },
};

We can still use the npm run preview command to run the dist folder because root: "./src" doesn't affect it (it still points to the main project folder).

Next, let's create about.html in the src folder and article.html in the blog folder.

<!-- ./src/about.html -->



  
    <meta charset="UTF-8">
    <link rel="icon" type="image/svg+xml" href="/vite.svg">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>About | Multipage Vite Vanilla JavaScript</title>
    <link rel="stylesheet" href="/style.css">
  
  
    <div>
      <h1 id="About-page">About page.</h1>
    </div>
  

<!-- ./src/blog/article.html -->



  
    <meta charset="UTF-8">
    <link rel="icon" type="image/svg+xml" href="/vite.svg">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Article | Multipage Vite Vanilla JavaScript</title>
    <link rel="stylesheet" href="/style.css">
  
  
    <div>
      <h1 id="Article-page">Article page.</h1>
    </div>
  

Then, add the following configuration so that both files are also created in the dist folder.

// vite.config.js

export default {
  root: "./src",
  build: {
    outDir: "../dist",
    emptyOutDir: true,
    rollupOptions: {
      input: {
        index: "./src/index.html",
        about: "./src/about.html",
        article: "./src/blog/article.html",
      },
    },
  },
};

Now the project is successfully multipage.

However, you might have noticed that we need to add a new path in input every time we create a new HTML file. If you want this to work dynamically, let's install the glob package and add the following configuration.

npm install -D glob

// vite.config.js

import { sync } from "glob";

export default {
  ...
  build: {
    ...
    rollupOptions: {
      input: sync("./src/**/*.html".replace(/\\/g, "/")),
    },
  },
};

Things that can be improved and added:

'404 Not Found' page

When we write the wrong url, the page displayed is the main page. We can make it show the default 'Not Found' page.

// vite.config.js

export default {
  appType: "mpa",
  root: "./src",
  ...

If we deploy the project to Netlify, we can easily redirect the default 'Not Found' page to our own 404 page.

Create 404.html in the src folder and _redirects file (without extension) in the public folder.

<!-- ./src/404.html -->



  
    <meta charset="UTF-8">
    <link rel="icon" type="image/svg+xml" href="/vite.svg">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Page not found | Multipage Vite Vanilla JavaScript</title>
    <link rel="stylesheet" href="/style.css">
  
  
    <div>
      <h1 id="Page-not-found">Page not found.</h1>
    </div>
  

_redirects

/* /404.html 200

Minify HTML

We can minify all HTML files during the build process using this plugin (let me know if I can do it without the plugin).

npm install -D vite-plugin-minify

// vite.config.js

...
import { ViteMinifyPlugin } from "vite-plugin-minify";

export default {
  plugins: [ViteMinifyPlugin()],
  appType: "mpa",
  ...

Create Path Aliases

// vite.config.js

...
import { resolve } from "path";

export default {
  resolve: {
    alias: {
      "@js": resolve(__dirname, "src/assets/js"),
    },
  },
  plugins: [ViteMinifyPlugin()],
  ...

// ./src/main.js

import { setupCounter } from "@js/counter";

import viteLogo from "/vite.svg";
...

To enable auto-suggestion in the text editor (VS Code), create a jsconfig.json file and add this configuration.

// jsconfig.json

{
  "compilerOptions": {
    "paths": {
      "@js/*": ["./src/assets/js/*"]
    }
  }
}

Install TailwindCSS

You can follow the official documentation.

npm install -D tailwindcss postcss autoprefixer
npx tailwindcss init

// tailwind.config.js

/** @type {import('tailwindcss').Config} */
export default {
  content: ["./src/**/*.{html,js}"],
  theme: {
    extend: {},
  },
  plugins: [],
};

// poscss.config.js

export default {
  plugins: {
    tailwindcss: {},
    autoprefixer: {},
  },
};

/* ./src/style.css */

@tailwind base;
@tailwind components;
@tailwind utilities;

root: {
  ...

To automatically sort TailwindCSS classes when using Prettier, you can follow this documentation.

npm install -D prettier prettier-plugin-tailwindcss

// .prettierrc

{
  "plugins": ["prettier-plugin-tailwindcss"]
}

Hope it helps you :)
