Static websites are great. I’m an enormous fan.
In addition they have their points. Specifically, static websites both are purely static or the frameworks that generate them fully lose out on true static era while you simply dip your toes within the route of server routes.
Astro has been watching the front-end ecosystem and is making an attempt to maintain one foot firmly embedded in pure static era, and the opposite in a strong set of server-side performance.
With Astro Actions, Astro brings a whole lot of the facility of the server to a website that’s nearly solely static. A very good instance of this kind of performance is coping with search. When you have a content-based website that may be purely generated, including search is both going to be one thing dealt with solely on the entrance finish, by way of a software-as-a-service answer, or, in different frameworks, changing your complete website to a server-side software.
With Astro, we will generate most of our website throughout our construct, however have a small little bit of server-side code that may deal with our search performance utilizing one thing like Fuse.js.
On this demo, we’ll use Fuse to go looking by way of a set of non-public “bookmarks” which might be generated at construct time, however return correct outcomes from a server name.
Beginning the venture
To get began, we’ll simply arrange a really primary Astro venture. In your terminal, run the next command:
npm create astro@newestAstro’s lovely mascot Houston goes to ask you a couple of questions in your terminal. Listed here are the fundamental responses, you’ll want:
- The place ought to we create your new venture? Wherever you’d like, however I’ll be calling my listing
./astro-search - How would you want to begin your new venture? Select the fundamental minimalist starter.
- Set up dependencies? Sure, please!
- Initialize a brand new git repository? I’d advocate it, personally!
It will create a listing within the location specified and set up every thing it’s worthwhile to begin an Astro venture. Open the listing in your code editor of alternative and run npm run dev in your terminal within the listing.
While you run your venture, you’ll see the default Astro venture homepage.
We’re able to get our venture rolling!
Primary setup
To get began, let’s take away the default content material from the homepage. Open the /src/pages/index.astro file.
This can be a pretty barebones homepage, however we wish it to be much more primary. Take away the <Welcome /> part, and we’ll have a pleasant clean web page.
For styling, let’s add Tailwind and a few very primary markup to the homepage to include our website.
npx astro add tailwindThe astro add command will set up Tailwind and try to arrange all of the boilerplate code for you (helpful!). The CLI will ask you if you would like it so as to add the assorted parts, I like to recommend letting it, but when something fails, you possibly can copy the code wanted from every of the steps within the course of. Because the final step for attending to work with Tailwind, the CLI will let you know to import the kinds right into a shared format. Observe these directions, and we will get to work.
Let’s add some very primary markup to our new homepage.
---
// ./src/pages/index.astro
import Structure from '../layouts/Structure.astro';
---
<Structure>
<div class="max-w-3xl mx-auto my-10">
<h1 class="text-3xl text-center">My newest bookmarks</h1>
<p class="text-xl text-center mb-5">That is solely 10 of A LARGE NUMBER THAT WE'LL CHANGE LATER</p>
</div>
</Structure>Your website ought to now seem like this.
Not precisely successful any awards but! That’s alright. Let’s get our bookmarks loaded in.
Including bookmark information with Astro Content material Layer
Since not everybody runs their very own software for bookmarking attention-grabbing objects, you possibly can borrow my information. Right here’s a small subset of my bookmarks, or you possibly can go get 110 objects from this link on GitHub. Add this information as a file in your venture. I prefer to group information in a information listing, so my file lives in /src/information/bookmarks.json.

]Now that the information is within the venture, we want for Astro to include the information into its construct course of. To do that, we will use Astro’s new(ish) Content Layer API. The Content material Layer API provides a content material configuration file to your src listing that permits you to run and gather any variety of content material items from information in your venture or exterior APIs. Create the file /src/content material.config.ts (the title of this file issues, as that is what Astro is on the lookout for in your venture).
import { defineCollection, z } from "astro:content material";
import { file } from 'astro/loaders';
const bookmarks = defineCollection({
schema: z.object({
pageTitle: z.string(),
url: z.string(),
description: z.string().non-compulsory()
}),
loader: file("src/information/bookmarks.json"),
});
export const collections = { bookmarks };On this file, we import a couple of helpers from Astro. We will use defineCollection to create the gathering, z as Zod, to assist outline our sorts, and file is a particular content material loader meant to learn information information.
The defineCollection methodology takes an object as its argument with a required loader and non-compulsory schema. The schema will assist make our content material type-safe and ensure our information is all the time what we count on it to be. On this case, we’ll outline the three information properties every of our bookmarks has. It’s vital to outline all of your information in your schema, in any other case it received’t be obtainable to your templates.
We offer the loader property with a content material loader. On this case, we’ll use the file loader that Astro offers and provides it the trail to our JSON.
Lastly, we have to export the collections variable as an object containing all of the collections that we’ve outlined (simply bookmarks in our venture). You’ll wish to restart the native server by re-running npm run dev in your terminal to select up the brand new information.
Utilizing the brand new bookmarks content material assortment
Now that we have now information, we will use it in our homepage to point out the newest bookmarks which have been added. To get the information, we have to entry the content material assortment with the getCollection methodology from astro:content material. Add the next code to the frontmatter for ./src/pages/index.astro .
---
import Structure from '../layouts/Structure.astro';
import { getCollection } from 'astro:content material';
const bookmarks = await getCollection('bookmarks');
---This code imports the getCollection methodology and makes use of it to create a brand new variable that incorporates the information in our bookmarksassortment. The bookmarks variable is an array of information, as outlined by the gathering, which we will use to loop by way of in our template.
---
import Structure from '../layouts/Structure.astro';
import { getCollection } from 'astro:content material';
const bookmarks = await getCollection('bookmarks');
---
<Structure>
<div class="max-w-3xl mx-auto my-10">
<h1 class="text-3xl text-center">My newest bookmarks</h1>
<p class="text-xl text-center mb-5">
That is solely 10 of {bookmarks.size}
</p>
<h2 class="text-2xl mb-3">Newest bookmarks</h2>
<ul class="grid gap-4">
{
bookmarks.slice(0, 10).map((merchandise) => (
<li>
<a
href={merchandise.information?.url}
class="block p-6 bg-white border border-gray-200 rounded-lg shadow-sm hover:bg-gray-100 darkish:bg-gray-800 darkish:border-gray-700 darkish:hover:bg-gray-700">
<h3 class="mb-2 text-2xl font-bold tracking-tight text-gray-900 darkish:text-white">
{merchandise.information?.pageTitle}
</h3>
<p class="font-normal text-gray-700 darkish:text-gray-400">
{merchandise.information?.description}
</p>
</a>
</li>
))
}
</ul>
</div>
</Structure>This could pull the newest 10 objects from the array and show them on the homepage with some Tailwind kinds. The primary factor to notice right here is that the information construction has modified just a little. The precise information for every merchandise in our array really resides within the information property of the merchandise. This permits Astro to place further information on the article with out colliding with any particulars we offer in our database. Your venture ought to now look one thing like this.
Now that we have now information and show, let’s get to work on our search performance.
Constructing search with actions and vanilla JavaScript
To begin, we’ll wish to scaffold out a brand new Astro part. In our instance, we’re going to make use of vanilla JavaScript, however should you’re aware of React or different frameworks that Astro helps, you possibly can go for shopper Islands to construct out your search. The Astro actions will work the identical.
Organising the part
We have to make a brand new part to accommodate a little bit of JavaScript and the HTML for the search discipline and outcomes. Create the part in a ./src/parts/Search.astro file.
<kind id="searchForm" class="flex mb-6 items-center max-w-sm mx-auto">
<label for="simple-search" class="sr-only">Search</label>
<div class="relative w-full">
<enter
kind="textual content"
id="search"
class="bg-gray-50 border border-gray-300 text-gray-900 text-sm rounded-lg focus:ring-blue-500 focus:border-blue-500 block w-full p-2.5 darkish:bg-gray-700 darkish:border-gray-600 darkish:placeholder-gray-400 darkish:text-white darkish:focus:ring-blue-500 darkish:focus:border-blue-500"
placeholder="Search Bookmarks"
required
/>
</div>
<button
kind="submit"
class="p-2.5 ms-2 text-sm font-medium text-white bg-blue-700 rounded-lg border border-blue-700 hover:bg-blue-800 focus:ring-4 focus:outline-none focus:ring-blue-300 darkish:bg-blue-600 darkish:hover:bg-blue-700 darkish:focus:ring-blue-800">
<svg
class="w-4 h-4"
aria-hidden="true"
xmlns="<http://www.w3.org/2000/svg>"
fill="none"
viewBox="0 0 20 20">
<path
stroke="currentColor"
stroke-linecap="spherical"
stroke-linejoin="spherical"
stroke-width="2"
d="m19 19-4-4m0-7A7 7 0 1 1 1 8a7 7 0 0 1 14 0Z"></path>
</svg>
<span class="sr-only">Search</span>
</button>
</kind>
<div class="grid gap-4 mb-10 hidden" id="outcomes">
<h2 class="text-xl font-bold mb-2">Search Outcomes</h2>
</div>
<script>
const kind = doc.getElementById("searchForm");
const search = doc.getElementById("search");
const outcomes = doc.getElementById("outcomes");
kind?.addEventListener("submit", async (e) => {
e.preventDefault();
console.log("SEARCH WILL HAPPEN");
});
</script>The fundamental HTML is organising a search kind, enter, and outcomes space with IDs that we’ll use in JavaScript. The fundamental JavaScript finds these parts, and for the shape, provides an occasion listener that fires when the shape is submitted. The occasion listener is the place a whole lot of our magic goes to occur, however for now, a console log will do to verify every thing is about up correctly.
Organising an Astro Motion for search
To ensure that Actions to work, we want our venture to permit for Astro to work in server or hybrid mode. These modes enable for all or some pages to be rendered in serverless features as an alternative of pre-generated as HTML through the construct. On this venture, this might be used for the Motion and nothing else, so we’ll go for hybrid mode.
To have the ability to run Astro on this manner, we have to add a server integration. Astro has integrations for many of the main cloud suppliers, in addition to a primary Node implementation. I sometimes host on Netlify, so we’ll set up their integration. Very like with Tailwind, we’ll use the CLI so as to add the bundle and it’ll construct out the boilerplate we want.
npx astro add netlifyAs soon as that is added, Astro is operating in Hybrid mode. Most of our website is pre-generated with HTML, however when the Motion will get used, it would run as a serverless operate.
Organising a really primary search Motion
Subsequent, we want an Astro Motion to deal with our search performance. To create the motion, we have to create a brand new file at ./src/actions/index.js. All our Actions stay on this file. You possibly can write the code for each in separate information and import them into this file, however on this instance, we solely have one Motion, and that appears like untimely optimization.
On this file, we’ll arrange our search Motion. Very like organising our content material collections, we’ll use a way referred to as defineAction and provides it a schema and on this case a handler. The schema will validate the information it’s getting from our JavaScript is typed accurately, and the handler will outline what occurs when the Motion runs.
import { defineAction } from "astro:actions";
import { z } from "astro:schema";
import { getCollection } from "astro:content material";
export const server = {
search: defineAction({
schema: z.object({
question: z.string(),
}),
handler: async (question) => {
const bookmarks = await getCollection("bookmarks");
const outcomes = await bookmarks.filter((bookmark) => {
return bookmark.information.pageTitle.contains(question);
});
return outcomes;
},
}),
};For our Motion, we’ll title it search and count on a schema of an object with a single property named question which is a string. The handler operate will get all of our bookmarks from the content material assortment and use a local JavaScript .filter() methodology to test if the question is included in any bookmark titles. This primary performance is able to check with our front-end.
Utilizing the Astro Motion within the search kind occasion
When the person submits the shape, we have to ship the question to our new Motion. As a substitute of determining the place to ship our fetch request, Astro offers us entry to all of our server Actions with the actions object in astro:actions. Which means any Motion we create is accessible from our client-side JavaScript.
In our Search part, we will now import our Motion immediately into the JavaScript after which use the search motion when the person submits the shape.
<script>
import { actions } from "astro:actions";
const kind = doc.getElementById("searchForm");
const search = doc.getElementById("search");
const outcomes = doc.getElementById("outcomes");
kind?.addEventListener("submit", async (e) => {
e.preventDefault();
outcomes.innerHTML = "";
const question = search.worth;
const { information, error } = await actions.search(question);
if (error) {
outcomes.innerHTML = `<p>${error.message}</p>`;
return;
}
// create a div for every search consequence
information.forEach(( merchandise ) => {
const div = doc.createElement("div");
div.innerHTML = `
<a href="https://css-tricks.com/powering-search-with-astro-actions-and-fuse-js/${merchandise.information?.url}" class="block p-6 bg-white border border-gray-200 rounded-lg shadow-sm hover:bg-gray-100 darkish:bg-gray-800 darkish:border-gray-700 darkish:hover:bg-gray-700">
<h3 class="mb-2 text-2xl font-bold tracking-tight text-gray-900 darkish:text-white">
${merchandise.information?.pageTitle}
</h3>
<p class="font-normal text-gray-700 darkish:text-gray-400">
${merchandise.information?.description}
</p>
</a>`;
// append the div to the outcomes container
outcomes.appendChild(div);
});
// present the outcomes container
outcomes.classList.take away("hidden");
});
</script>When outcomes are returned, we will now get search outcomes!
Although, they’re extremely problematic. That is only a easy JavaScript filter, in any case. You possibly can seek for “Favourite” and get my favourite bread recipe, however should you seek for “favourite” (no caps), you’ll get an error… Not perfect.
That’s why we should always use a bundle like Fuse.js.
Including Fuse.js for fuzzy search
Fuse.js is a JavaScript bundle that has utilities to make “fuzzy” search a lot simpler for builders. Fuse will settle for a string and based mostly on quite a lot of standards (and quite a lot of units of information) present responses that intently match even when the match isn’t excellent. Relying on the settings, Fuse can match “Favourite”, “favourite”, and even misspellings like “favrite” all to the precise outcomes.
Is Fuse as highly effective as one thing like Algolia or ElasticSearch? No. Is it free and fairly darned good? Completely! To get Fuse shifting, we have to set up it into our venture.
npm set up fuse.jsFrom there, we will use it in our Motion by importing it within the file and creating a brand new occasion of Fuse based mostly on our bookmarks assortment.
import { defineAction } from "astro:actions";
import { z } from "astro:schema";
import { getCollection } from "astro:content material";
import Fuse from "fuse.js";
export const server = {
search: defineAction({
schema: z.object({
question: z.string(),
}),
handler: async (question) => {
const bookmarks = await getCollection("bookmarks");
const fuse = new Fuse(bookmarks, {
threshold: 0.3,
keys: [
{ name: "data.pageTitle", weight: 1.0 },
{ name: "data.description", weight: 0.7 },
{ name: "data.url", weight: 0.3 },
],
});
const outcomes = await fuse.search(question);
return outcomes;
},
}),
};On this case, we create the Fuse occasion with a couple of choices. We give it a threshold worth between 0 and 1 to resolve how “fuzzy” to make the search. Fuzziness is unquestionably one thing that relies on use case and the dataset. In our dataset, I’ve discovered 0.3 to be a fantastic threshold.
The keys array permits you to specify which information needs to be searched. On this case, I need all the information to be searched, however I wish to enable for various weighting for every merchandise. The title needs to be most vital, adopted by the outline, and the URL needs to be final. This manner, I can seek for key phrases in all these areas.
As soon as there’s a brand new Fuse occasion, we run fuse.search(question) to have Fuse test the information, and return an array of outcomes.
After we run this with our front-end, we discover we have now yet one more challenge to deal with.
The construction of the information returned will not be fairly what it was with our easy JavaScript. Every consequence now has a refIndex and an merchandise. All our information lives on the merchandise, so we have to destructure the merchandise off of every returned consequence.
To try this, modify the front-end forEach.
// create a div for every search consequence
information.forEach(({ merchandise }) => {
const div = doc.createElement("div");
div.innerHTML = `
<a href="https://css-tricks.com/powering-search-with-astro-actions-and-fuse-js/${merchandise.information?.url}" class="block p-6 bg-white border border-gray-200 rounded-lg shadow-sm hover:bg-gray-100 darkish:bg-gray-800 darkish:border-gray-700 darkish:hover:bg-gray-700">
<h3 class="mb-2 text-2xl font-bold tracking-tight text-gray-900 darkish:text-white">
${merchandise.information?.pageTitle}
</h3>
<p class="font-normal text-gray-700 darkish:text-gray-400">
${merchandise.information?.description}
</p>
</a>`;
// append the div to the outcomes container
outcomes.appendChild(div);
});Now, we have now a totally working seek for our bookmarks.
Subsequent steps
This simply scratches the floor of what you are able to do with Astro Actions. As an illustration, we should always in all probability add further error dealing with based mostly on the error we get again. You may also experiment with dealing with this on the page-level and letting there be a Search web page the place the Motion is used as a kind motion and handles all of it as a server request as an alternative of with front-end JavaScript code. You might additionally refactor the JavaScript from the admittedly low-tech vanilla JS to one thing a bit extra sturdy with React, Svelte, or Vue.
One factor is for positive, Astro retains wanting on the front-end panorama and studying from the errors and greatest practices of all the opposite frameworks. Actions, Content material Layer, and extra are only the start for a very compelling front-end framework.
