Implement Search with Pagefind

The site is having more and more of blog posts now. And sometimes, when I need to find a specific post, it takes time. So a search function is much needed. After some quick research, I found a library called Pagefind. It is a search engine that can be integrated with any static site generator. In this post, I will walk you through the basic way to integrate it so that you can have something like this:

#Why Pagefind?

There are a few reasons why I decided to go with Pagefind:

• Static site compatibility: Pagefind is designed specifically for static websites, making it an excellent choice for JAMstack and other static site architectures.
• Lightweight: The library is very lightweight, adding minimal overhead to your site.
• Easy setup: Pagefind can be implemented with minimal configuration, often requiring just a single line of JavaScript.
• No external dependencies: It doesn't rely on external services or APIs, which can improve reliability and reduce costs.
• Automatic index generation: Pagefind automatically generates a search index from your static site content.
• Fast performance: The library offers quick search results, even on large sites. You can check out their demo on MDN Web Docs, very impressive.
• Multilingual support: Pagefind can handle content in multiple languages.

#Installation

First, you need to install the library itself and the default stylesheet. You can do it by running the following command:

npm install --save-dev pagefind @pagefind/default-ui

#Configuration

#Indexing

In order for Pagefind to work, it needs to index your site. Let's say you have your build output in the dist folder. You can run the following command to index it:

pagefind --source dist

But we want to run automatic after every build. So we need to add a script to our package.json file:

{
  //...
  "scripts": {
    //...
    "postbuild": "pagefind --source dist"
  }
  //...
}

#Search UI

It depends on the way you want to have the search UI. In the example above, I use the default UI with very little tweaks wrapped in a modal. Inside of the modal, you can place an element with an specific id like:

<div id="pagefind__search"></div>

Then in the script, you can import the default UI and initialize it :

const { PagefindUI } = await import('@pagefind/default-ui')
const _pagefindUI = new PagefindUI({
  element: '#pagefind__search',
  baseUrl: import.meta.env.BASE_URL,
  bundlePath: `${import.meta.env.BASE_URL.replace(/\/$/, '')}/pagefind/`,
  showImages: false,
})

You can also customize the styles using the CSS custom properties listed in the documentation. And if you want to see how I implemented it, check out Search.vue.
