Xata

Xata Open external link is a serverless data platform powered by PostgreSQL. Xata uniquely combines multiple types of stores (relational databases, search engines, analytics engines) into a single service, accessible through a consistent REST API.

​​ Set up an integration with Xata

To set up an integration with Xata:

1. You need to have an existing Xata database to connect to or create a new database from your Xata workspace Create a Database Open external link .

2. In your database, you have several options for creating a table: you can start from scratch, use a template filled with sample data, or import data from a CSV file. For this guide, choose Start with sample data. This option automatically populates your database with two sample tables: Posts and Users.

3. Add the Xata integration to your Worker:

   1. Log in to the Cloudflare dashboard Open external link and select your account.
   2. In Account Home, select Workers & Pages.
   3. In Overview, select your Worker.
   4. Select Integrations > Xata.
   5. Follow the setup flow, selecting the database created in step 1.

4. Install the Xata CLI Open external link and authenticate the CLI by running the following commands:

   $ npm install -g @xata.io/cli
   
   $ xata auth login
   

5. Once you have the CLI set up, In your Worker, run the following code in the root directory of your project:

   $ xata init
   

   Accept the default settings during the configuration process. After completion, a .env and .xatarc file will be generated in your project folder.

6. To enable Cloudflare access the secret values generated when running in development mode, create a .dev.vars file in your project’s root directory and add the following content, replacing placeholders with the specific values:

   XATA_API_KEY=<YOUR_API_KEY_HERE>
   XATA_BRANCH=<YOUR_BRANCH_HERE>
   XATA_DATABASE_URL=<YOUR_DATABASE_URL_HERE>

7. The following example shows how to make a query to your Xata database in a Worker. The credentials needed to connect to Xata have been automatically added as secrets to your Worker through the integration.

   Worker code
   export default {
     async fetch(request, env, ctx): Promise<Response> {
       const xata = new XataClient({
         apiKey: env.XATA_API_KEY,
         branch: env.XATA_BRANCH,
         databaseURL: env.XATA_DATABASE_URL,
       });
   
       const records = await xata.db.Posts.select([
         "id",
         "title",
         "author.name",
         "author.email",
         "author.bio",
       ]).getAll();
   
       return Response.json(records);
     },
   } satisfies ExportedHandler<Env>;
