This is my approach to a purely client side search feature for static blogs and sites.

I am currently using this under /posts to let readers search through my blog posts.

Read more below about how to integrate it in your site.


In 2015 I did a similar thing for Jekyll sites, namely Simple-Jekyll-Search

It’s gotten quite a bit of attention and merged various Pull-Requests (64!) from others.

I ditched Jekyll a few years ago, to use a JavaScript based static site generator:

My home-made static site generator devblog, and settled with Eleventy

How it works

Under /posts I render the full list of blog posts.

(Not with the full content but with an excerpt/description.)

In my Nunjucks template I render the posts like this:

<div class="searchable">
<input type="text" autofocus placeholder="🔍 Search posts"/>
{% set postslist = | reverse %}
{% for post in postslist %}
<div class="searchable-item" data-search="{{ | escape }} {{ | json | escape }}">
{% endfor %}

The idea is the following:

Within a .searchable element

  • look for a input element and attach an event listener to it (keyup event)
  • when searching, parse all .searchable-items data-search attribute and test a RegExp on it
  • make items that match visible, and make others disappear


This is the full code for the search functionality on this blog:

;(function search () {
function makeSearchable ($searchable) {
const $searchableItems = [...$searchable.querySelectorAll('.searchable-item')]
const $search = $searchable.querySelector('input')
$search.addEventListener('keyup', (e) => {
$searchableItems.forEach(function ($el) {
const text = $el.getAttribute('data-search') || $el.innerText
const show = new RegExp(, 'i').test(text)
$ = show ? '' : 'none'

How to integrate it on your site

Grabbed the JavaScript above and put it in a <script> tag.

Define a minimal markup to enable the search functionality:

<div class="searchable">
<input type="text" autofocus placeholder="🔍 Search posts"/>
<!-- Loop through your blog posts -->
<div class="searchable-item">

Make sure you have the wrapper element .searchable, containing an input field and your post items with the .searchable-item class.

By default the search function will match the blog posts to filter with the element’s innerText.

Optionally, apply a data-search attribute to each .searchable-item and set the value of your blog post title, tags, short description etc.
