Before embarking on creating our blog, it is essential to understand what VitePress is and its origins. Familiarity with the tools we utilize for our blog creation is crucial.

According to the homepage:

Vite & Vue Powered Static Site Generator, Markdown to Beautiful Docs in Minutes

While the tagline's use of "docs" might suggest VitePress is exclusively for documentation websites, it can create any content-centric website.

The "What is VitePress?" section explains:

VitePress is a Static Site Generator (SSG) designed for building fast, content-centric websites. In a nutshell, VitePress takes your source content written in Markdown, applies a theme to it, and generates static HTML pages that can be easily deployed anywhere.

In essence, VitePress builds upon a basic Vite and Vue application, similar to what you could generate with npx create-vite --template vue. However, VitePress offers much more.

It introduces three key features to the standard Vite and Vue application:

  1. Markdown Support: VitePress comes with a pre-configured Markdown to HTML compiler based on markdown-it. It inherently supports frontmatter, syntax highlighting, GitHub-style alerts, emojis, Vue components, and more. It leverages a comprehensive configuration with numerous plugins. You can review the source code for more insight.
  2. Data Loading: VitePress enables data loading from the file system, networks, or any other sources. This potent feature facilitates the creation of dynamic websites using a static site generator.
  3. Pre-rendering at Build-time: VitePress operates as a Single Page Application (SPA), enhancing User Experience (UX) but challenging Search Engine Optimization (SEO). However, due to its markdown-centric static content nature, VitePress pre-renders pages during build-time, resulting in static HTML files. This approach is excellent for SEO while maintaining SPA benefits for UX. It cleverly employs Server Side Rendering (SSR) capabilities of Vue, which you can observe in the source code.

These elements constitute VitePress's foundation, making it ideal for creating blogs, documentation, and other content-focused websites. While it supports dynamic data, that aspect will be explored in another series.

Equipped with a default theme, VitePress facilitates attractive documentation websites. The default theme, available for exploration in the VitePress documentation and its source code, is simply a built-in Vue library comprising components, composables, and CSS, easy to override for creating custom themes.

Understanding the tagline's real implication clarifies why VitePress is chosen for developing a blog; it's a versatile tool for content-centric websites beyond just documentation.

Note

Attempting to utilize a custom Vite and Vue application is ill-advised. VitePress's complexity and configuration management save considerable time, both now and during future blog updates.

History

Developed by Evan You alongside Vite, VitePress tested Vite in a real-world setting, ensuring its practicality and user-friendliness. VitePress evolved from its predecessor VuePress, upgrading from Webpack and Vue 2 to Vite and Vue 3, offering significant performance and developer experience enhancements.

VitePress is popular for creating documentation sites or blogs like The Vue Point, the official Vue.js blog. Its thin layer over Vite ensures it remains highly extendable and customizable, with assurances of continued support.

Initializing the Project

Armed with a better understanding of VitePress, we can initiate a fresh project called "Garabit." You can access the source code on garabit.

Despite being initially tailored for documentation sites within existing projects, the installation process could be smoother. I have highlighted this in two pull requests on the VitePress repository: feat(cli): support custom npm scripts prefix and feat(cli): support custom srcDir.

First, create a folder for our project:

bash
mkdir garabit

Then, initialize npm inside this folder and install VitePress:

bash
pnpm init
pnpm add -D vitepress

Note

Throughout this series, I will use pnpm as the package manager, but you can adapt the commands for your preferred package manager.

Finally, scaffold the VitePress project:

bash
pnpm vitepress init

Respond to the prompts (press enter for default values, which we will adjust later):

bash
  Welcome to VitePress!

  Where should VitePress initialize the config?
  ./

  Site title:
  My Awesome Project

  Site description:
  A VitePress Site

  Theme:
  Default Theme

  Use TypeScript for config and theme files?
  Yes

  Add VitePress npm scripts to package.json?
  Yes

  Done! Now run pnpm run docs:dev and start writing.

Exploring the Project

We now have a freshly minted VitePress project. Let's examine the project structure:

bash
.
├── .vitepress
   └── config.mts
├── api-examples.md
├── index.md
├── markdown-examples.md
├── package.json
└── pnpm-lock.yaml

The root level contains our Markdown files, representing our blog's pages, with filenames (and directories) corresponding to page URLs. index.md serves as the homepage. Although this structure is basic, we will refine it in future articles.

Being content-focused, VitePress's configuration and theme-related elements reside within the .vitepress directory, where the config.mts file configures the theme, plugins, data loading, and more, written in TypeScript. We will delve into this in upcoming articles.

Enhancing the Developer Experience (DX)

While suitable for documentation websites, our custom blog requires additional dependencies to enhance the developer experience (DX). We will incorporate two dependencies:

Tailwind CSS

We will leverage Tailwind CSS for styling our custom theme. This utility-first CSS framework offers powerful, user-friendly design capabilities.

Begin by installing Tailwind CSS:

bash
pnpm add -D tailwindcss postcss autoprefixer

Create the configuration file for Tailwind CSS:

bash
npx tailwindcss init -p

We'll configure Tailwind CSS as we progress.

Auto-import Vue Components

We'll use unplugin-vue-components for automatic Vue component importation, a Vite plugin enabling on-demand component importation. This automated process significantly saves time by eliminating manual importation per file. Components are not globally available, mitigating performance impact, as our files are transformed via a rollup plugin, adding an import at the file's top solely if the component is utilized—a testament to the on-demand philosophy.

First, install unplugin-vue-components:

bash
pnpm add -D unplugin-vue-components

Then, integrate it into the config.mts file:

typescript
import Components from 'unplugin-vue-components/vite'
import { defineConfig } from 'vitepress'

export default defineConfig({
  // ...
  vite: {
    plugins: [Components()],
  },
})

We will configure unplugin-vue-components more thoroughly later.

Ready for the Next Step

With our VitePress project now featuring Tailwind CSS and unplugin-vue-components, we are poised to begin developing our blog.

In the subsequent article, we will examine VitePress fundamentals and craft a personalized theme for our blog.
