Get started with Astro and Xata

In this guide, you'll create a new Astro application and walk through adding Xata database and search functionality. You'll build the following basic blog application features:

1. List all blog posts
2. Retrieve and view a single blog post
3. Full-text fuzzy search of blog posts

Although this application is a simple blog, you can apply these basics to other types of Astro applications.

The completed Astro and Xata code for this guide is available via the Xata examples repo on GitHub.

Install the Xata CLI:

npm install -g @xata.io/cli

npm install -g '@xata.io/cli'

Once installed, authenticate the Xata CLI with your Xata account. If you don't already have an account, you can use the same workflow to sign up for a new account. Run the following command to begin the authentication workflow:

xata auth login

Upon completion, the command will generate a new API key for your user account. You should be able to view this key in the "Account Settings" page in the Xata UI. That key will also be stored locally on your computer (the location might vary for each OS). It looks like this:

# .config/xata/credentials
[default]
apiKey=YOUR_API_KEY_HERE

Begin by creating a new Astro application with a template setup to use Tailwind CSS for some styling. Run the following command and accept all the prompt defaults:

npm create astro@latest -- --template with-tailwindcss xata-astro

$ npm create astro@latest -- --template with-tailwindcss xata-astro

Once the command has completed, go to the xata-astro directory and run the application:

cd xata-astro
npm run dev

By default, the application will run on http://localhost:3000.

Once you have the Xata CLI installed, are logged in, and have set up a new Astro application, you are ready to use the Xata CLI to generate a new database. Accept all the prompt defaults for the following command, except for the region selection. Choose the region closest to your application's users:

xata init

i Use xata pull main to regenerate code and types from your Xata database

On completion, the CLI will create .env, .xatarc, and src/xata.ts files within your project folder with the correct credentials to access your database.

Your .env file should look something like this:

XATA_API_KEY=YOUR_API_KEY_HERE
XATA_BRANCH=main

To inform the TypeScript typechecking about these new environment variables, update src/env.d.ts as follows:

/// <reference types="astro/client" />

interface ImportMetaEnv {
  readonly XATA_API_KEY: string;
  readonly XATA_BRANCH?: string;
}

interface ImportMeta {
  readonly env: ImportMetaEnv;
}

Since TypeScript support was selected, it also created files that provide typings and functions to call using Xata's TypeScript SDK. This will additionally be referenced in the .xatarc file as follows:

{
  "databaseUrl": "https://my-xata-app-database-url",
  "codegen": {
    "output": "src/xata.ts"
  }
}

The src/xata.ts file includes generated code you should typically never touch manually.

You can use the Xata UI to manually define your schema and add data. However, for this guide, you'll walk through using the Xata CLI and a CSV file to:

1. Auto-generate a schema based on column headings for names and data types inferred from the column values
2. Import data to the database

First, download the CSV file of blog posts. You can either do this manually or by running the following command:

curl --create-dirs -o seed/blog-posts.csv https://raw.githubusercontent.com/xataio/examples/main/seed/blog-posts.csv

curl.exe --create-dirs -o seed/blog-posts.csv https://raw.githubusercontent.com/xataio/examples/main/seed/blog-posts.csv

Next, import the CSV:

xata import csv seed/blog-posts.csv --table Posts --create

$ xata import csv seed/blog-posts.csv --table Posts --create
i 45 rows successfully imported 0 errors. 100% complete
✔ Completed

Now, if you open up the Xata UI and navigate to your database, you will see the Posts table. Alternatively, you can run the command xata browse to open a browser window:

Click Schema to see the schema definition with the inferred data types:

You'll also see xata.* special columns automatically created and maintained by Xata.

With the database schema in place, the final step is to generate the code to access and query the data from our Astro application. To do this, run:

xata pull main

$ xata pull main
Successfully pulled 1 migrations from main branch
Running codegen...
Generated Xata code to ./src/xata.ts

This updates the contents of src/xata.ts based on the schema defined on the main branch of our database. So, if you make any further changes to the schema, run xata pull <branch> to update the auto-generated code.

Replace the contents of src/layouts/main.astro with the following:

---
const { title } = Astro.props;
---

<html lang="en">
  <head>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width" />
    <link rel="icon" type="image/svg+xml" href="/favicon.svg" />
    <title>{title}</title>
    <style>
      :root {
        --foreground-rgb: 0, 0, 0;
        --background-start-rgb: 214, 219, 220;
        --background-end-rgb: 255, 255, 255;
      }

      @media (prefers-color-scheme: dark) {
        :root {
          --foreground-rgb: 255, 255, 255;
          --background-start-rgb: 0, 0, 0;
          --background-end-rgb: 0, 0, 0;
        }
      }

      body {
        color: rgb(var(--foreground-rgb));
        background: linear-gradient(
            to bottom,
            transparent,
            rgb(var(--background-end-rgb))
          )
          rgb(var(--background-start-rgb));
      }
    </style>
  </head>

        <p class="fixed left-0 top-0 flex w-full justify-center pb-6 pt-8 lg:static lg:w-auto bg-gradient-to-b from-white via-white via-65% dark:from-black dark:via-black lg:bg-none">
          <a href="/">Get started with Xata and Astro</a>
        </p>
        <div class="fixed bottom-0 left-0 flex w-full items-end justify-center bg-gradient-to-t from-white via-white dark:from-black dark:via-black lg:static lg:h-auto lg:w-auto lg:bg-none">

            <img src="https://raw.githubusercontent.com/xataio/examples/main/docs/app_logo.svg" />
          </a>
        </div>
      </div>
      <slot />
    </main>
  </body>
</html>

The two main points to be aware of in this layout are:

1. This layout has a title property that sets the page <title />.
2. The contents of the pages that use this layout will appear where <slot /> is defined.

Now, you are ready to integrate Xata into the Astro codebase. Start by updating the landing page, src/pages/index.astro, to use the layout:

---
import MainLayout from '../layouts/main.astro';
---

<MainLayout title="Get started with Xata and Astro">

  <div class="w-full max-w-5xl mt-16">No posts</div>

</MainLayout>

Next, import the auto-generated XataClient class definition from src/xata.ts, get all the posts using the client, and list them within the page:

---
import MainLayout from '../layouts/main.astro';

import { XataClient } from '../xata';

const xata = new XataClient({
  apiKey: import.meta.env.XATA_API_KEY,
  branch: import.meta.env.XATA_BRANCH
});

let posts = await xata.db.Posts.getAll();
---

<MainLayout title="Get started with Xata and Astro">

  <div class="w-full max-w-5xl mt-16">
    {posts.length === 0 && <p>No blog posts found</p>}
    {posts.map((posts) => (
      <div class="mb-16">
        <p class="text-xs mb-2 text-purple-950 dark:text-purple-200">
          {posts.pubDate?.toDateString()}
        </p>
        <h2 class="text-2xl mb-2">
          <a href={`posts/${posts.slug}`}>{posts.title}</a>
        </h2>
        <p class="text-purple-950 dark:text-purple-200 mb-5">
          {posts.description}
        </p>
        <a
          href={`posts/${posts.slug}`}
          class="px-4 py-2 font-semibold text-sm bg-purple-700 text-white rounded-lg shadow-sm w-fit"
        >
          Read more &rarr;
        </a>
      </div>
    ))}
  </div>

</MainLayout>

Here's a breakdown of what's happening in the code above.

First, import the XataClient constructor and create a new instance, passing in the apiKey and branch with the values set via the XATA_API_KEY and XATA_XATA_BRANCH environment variables, respectively. Then assign the XataClient instance to a variable named xata:

import { XataClient } from '../xata';

const xata = new XataClient({
  apiKey: import.meta.env.XATA_API_KEY,
  branch: import.meta.env.XATA_BRANCH
});

Then, in the Astro page Component Script (the section within ---), use the xata client instance to get all the posts stored in the database. This is achieved via the auto-generated Posts property, which exposes a number of helper functions. In this case, use the getAll function to get all the Post records.

let posts = await xata.db.Posts.getAll();

Finally, update the UI to display the result of the getAll call. If no Post records are present (posts.length === 0), show a message saying, "No blog posts found". Otherwise, loop through the posts using posts.map and access the columns of each Post record using their properties: id as a unique identifier for the key attribute, pubDate to show the date the blog post was published, slug to link to individual blog posts (which you'll use later), title for the title of the post, and description for the textual description of the post:

<div class="w-full max-w-5xl mt-16">
  {posts.length === 0 && <p>No blog posts found</p>}
  {posts.map((posts) => (
    <div class="mb-16">
      <p class="text-xs mb-2 text-purple-950 dark:text-purple-200">{posts.pubDate?.toDateString()}</p>
      <h2 class="text-2xl mb-2">
        <a href={`posts/${posts.slug}`}>{posts.title}</a>
      </h2>
      <p class="text-purple-950 dark:text-purple-200 mb-5">{posts.description}</p>
      <a
        href={`posts/${posts.slug}`}
        class="px-4 py-2 font-semibold text-sm bg-purple-700 text-white rounded-lg shadow-sm w-fit"
      >
        Read more &rarr;
      </a>
    </div>
  ))}
</div>

This results in the page looking like the following:

You'll notice that the post heading and "Read more →" text use the slug property to link to a page that doesn't presently exist. That's the next step in this guide.

You access a single post via the slug value of the Post in the application's URL. For example, /posts/awesome-blog-post where awesome-blog-post is the slug. You achieve this using Astro's dynamic routes. You identify parameters within Astro dynamic routes by a name within square brackets in the file path. For example, lang and version within src/pages/[lang]/[version]/info.astro.

Astro is in SSG (Static Site Generator) mode by default, meaning that all routes are identified within the getStaticPaths function, and site content is generated at build time. Since all the blog posts and their slug are defined within the Posts table, you can query the table for all posts and inform the framework about all possible routes and content.

Create a new file, src/pages/posts/[slug].astro to enable access to a slug parameter:

---
import MainLayout from '../../layouts/main.astro'

import { XataClient } from '../../xata';

export async function getStaticPaths() {
  const xata = new XataClient({
    apiKey: import.meta.env.XATA_API_KEY,
    branch: import.meta.env.XATA_BRANCH
  });
  const posts = await xata.db.Posts.getAll();

  const routes = posts.map(({ slug, title, description, pubDate }) => {
    return {
      params: { slug },
      props: { title, description, pubDate },
    };
  });

  return routes;
}

const post = Astro.props;
---

<MainLayout title={post.title}>

  <div class="w-full max-w-5xl mt-16">
    <p class="mb-2">
      <a href="/" class="text-purple-600">
        &larr; Back to blog
      </a>
    </p>

    <h1 class="text-3xl mb-2">{post?.title}</h1>
    <p class="text-sm mb-4 text-purple-950 dark:text-purple-200">
      {post?.pubDate?.toDateString()}
    </p>
    <p class="text-xl">{post?.description}</p>

  </div>

</MainLayout>

As discussed, this defines all static pages, their content, and how to render the post details for a single blog post view. Here's a breakdown.

From the code above, the MainLayout is imported to be used within the Astro Component Template:

import MainLayout from '../../layouts/main.astro';

Next, import the XataClient class definition from the auto-generated xata.ts file to be used within getStaticPaths:

import { XataClient } from '../../xata';

The getStaticPaths Astro framework function is then declared. First, instantiate an instance of the XataClient object, passing in the apiKey with a value assigned via the XATA_API_KEY environment variable. Then, get all the Post records using xata.db.Posts.getAll. The next step is to create a map to inform Astro of the possible routes with a slug parameter and pass the properties associated with each route: the title, description, and pubDate are returned as props for each slug. Finally, return the routes array from the function.

export async function getStaticPaths() {
  const xata = new XataClient({
    apiKey: import.meta.env.XATA_API_KEY,
    branch: import.meta.env.XATA_BRANCH
  });
  const posts = await xata.db.Posts.getAll();

  const routes = posts.map(({ slug, title, description, pubDate }) => {
    return {
      params: { slug },
      props: { title, description, pubDate }
    };
  });

  return routes;
}

The last line within the Component Script section of [slug].astro pulls the properties returned from getStaticPaths for the current slug generated as part of the Astro Static Site Generate process. So, post represents a single post and contains properties for title, description, and pubDate.

The Component Template (the contents after the second ---) uses the MainLayout component and passes the blog post title, post.title, used within <title>. Finally, the values for post.title, post.description, and post.pubDate are then used within the UI.

...

const post = Astro.props;
---

<MainLayout title={post.title}>

  <div class="w-full max-w-5xl mt-16">
    <p class="mb-2">
      <a href="/" class="text-purple-600">
        &larr; Back to blog
      </a>
    </p>

    <h1 class="text-3xl mb-2">{post?.title}</h1>
    <p class="text-sm mb-4 text-purple-950 dark:text-purple-200">
      {post?.pubDate?.toDateString()}
    </p>
    <p class="text-xl">{post?.description}</p>

  </div>

</MainLayout>

The single blog post page will look as follows:

The last piece of functionality to add to the application is full-text fuzzy search of blog posts.

When you insert data into a Xata database, it is automatically indexed for full-text search. So you don't need to change any configuration to enable search, you just need to use the TypeScript SDK search feature.

As mentioned earlier, by default, Astro is in SSG Mode. However, generating static paths for all possible user search values is impossible. So, for dynamically generated pages such as search results, Server Side Rendering (SSR) is required. Astro supports a "hybrid" mode for sites that use SSG and SSR. You enable this within apps/getting-started-astro/astro.config.mjs as follows:

import { defineConfig } from 'astro/config';

import tailwind from '@astrojs/tailwind';

// https://astro.build/config
export default defineConfig({
  integrations: [tailwind()],
  output: 'hybrid'
});

With output set to hybrid, static pages continue to work as they did previously. Now, you are ready to add the search functionality.

Adding search is as simple as updating the landing page as follows:

---
import MainLayout from '../layouts/main.astro';

import { XataClient } from '../xata';

const xata = new XataClient({
  apiKey: import.meta.env.XATA_API_KEY,
  branch: import.meta.env.XATA_BRANCH
});

const search = Astro.url.searchParams.get('q')! || '';

let posts = null;
if (search) {
  const { records } = await xata.db.Posts.search(search, { fuzziness: 2 });
  posts = records;
} else {
  posts = await xata.db.Posts.getAll();
}
---

<MainLayout title="Get started with Xata and Astro">
  <div class="w-full max-w-5xl mt-16">
    <form action="/">
      <input
        name="q"
        value={search}
        placeholder="Search..."
        class="w-full rounded-lg border-2 p-2 dark:text-purple-950"
      />
    </form>
  </div>

  ...

</MainLayout>

First, update the Component Script to retrieve the q query string value and assign the result to a search variable. If the query string parameter is not present, set the value to an empty string.

const search = Astro.url.searchParams.get('q')! || '';

Second, the landing page should list all blog posts if search is an empty string. However, if the search contains a value, a search is performed on the Posts table using the search function exposed on the auto-generated Posts property. Pass search as the text value to search for, and use a second options parameter with fuzziness set to 2, which informs the fuzzy search behavior to allow for two letters changed/added/removed. See fuzziness and typo tolerance for more details.

let posts = null;
if (search) {
  const { records } = await xata.db.Posts.search(search, { fuzziness: 2 });
  posts = records;
} else {
  posts = await xata.db.Posts.getAll();
}

The third and last change is to add a <form> to the page to allow a search value to be entered and submitted. The default behavior of a form is to submit a GET request to the current URL with any form inputs added to the query string in the format {url}/?{input-name}={input-value}. For our search form, the result of a form submission is a GETrequest in the format?q={q-value}.

In addition to posts being dynamically populated based on the search result, the search value is also used within the <input value={search} /> of the <form /> to inform the user of the current search.

Since this is precisely the behavior required, and the page is already updated to get the value of q via Astro.url.searchParams.get('q'), everything is now in place.

<div class="w-full max-w-5xl mt-16">
  <form action="/">
    <input
      name="q"
      value={search}
      placeholder="Search..."
      class="w-full rounded-lg border-2 p-2 dark:text-purple-950"
    />
  </form>
</div>

The application now supports listing posts, viewing single posts via a dynamic route, and full-text fuzzy search of posts.

In this guide, you've learned Astro with SSG (Static Site Generation) and SSR (Server-Side Rendering), and Xata is a powerful combination. You created an application from scratch that lists blog posts, supports viewing a single blog post, and performs full-text fuzzy search on all posts.

You walked through setting up the Xata CLI and using it to:

• Create a new Xata project
• Create a database schema and populate it with data from an imported CSV file
• Update the auto-generated code (in src/xata.ts) using xata pull main to reflect the updated schema

You then updated the landing page to list all blog posts, making use of the auto-generated xata.db.Posts.getAll function. You also added the single post page using Astro SSG, where the slug Posts record column was used in combination with Astro's getStaticPaths to identify all possible routes and, thus, the static files to be generated.

Finally, you added full-text fuzzy search functionality to the landing page, leveraging Xata's automatic table indexing. To do this, you enabled Astro's hybrid mode to generate search results using SSR based on the search query passed in the q query string and the results from the auto-generated xata.db.Posts.search function.

If you enjoyed this guide, you could continue working on improving the application. Here are some suggestions:

• Add pagination for the blog post listing
• Add pagination for blog post search results
• Handle single post view page not finding a result for a slug
• Add a body field to the database schema to contain the full text of the blog post and update the single page view to use that new field

You can explore some of the features covered in more detail:

• Getting records
• Filtering records
• Searching records

Or dive into some of Xata's more advanced features, such as:

• Aggregations
• Transactions
• Vector search
