By the end of this tutorial, you'll have a solid understanding of how to set up, develop, and release an Airtable extension. Let's dive in!

Introduction

Creating extensions in Airtable allows you to customize functionalities tailored to specific needs, providing a seamless and personalized experience. This guide will walk you through the entire process, ensuring you have a working extension by the end.

Setting Up Your Airtable Base

To start, let's create a new Airtable base from scratch. While the base’s name doesn't matter for this tutorial, we'll call it “Extensions!” for simplicity.

1. Create a New Base:

   • Go to your Airtable dashboard.
   • Click on "Add a base."
   • Name your base “Extensions!”

2. Navigate to Extensions:

   • Click the “Extensions” button at the top-right of the screen.
   • This will open the Extensions dashboard.

Creating a New Extension

From the Extensions dashboard, we will initiate the creation of our new extension:

1. Install a New Extension:

   • Click “Install an extension.”
   • Select “Build a custom extension.”

2. Name Your Extension:

   • For the purpose of this guide, name it “Hello Extensions.”

3. Create and Configure:

   • Click “Create extension” to proceed.
   • Follow the on-screen instructions to open your terminal and install the Airtable Blocks command line tool.

4. Verify Installation:

   • In your terminal, check the correct version of blocks-cli by running the following command:

   block --version

5. Initialize Your Project:

   • Run block init with the necessary arguments.
   • Input your Airtable personal access token (with block:manage scope).

6. Navigate to Your Project:

   • Move to your project directory by running:

   cd hello_extensions

7. Run Your Extension:

   • Start your extension with:

   block run

Developing Your Extension

Now that your environment is set up, let's make some changes to see it in action.

1. Locate Frontend File:

   • Open frontend/index.js in your text editor.

2. Modify Output:

   • Change the text from “Hello world 🚀” to another message, like:

   const message = "Goodbye, Earth! 🌍";

3. Save and Refresh:

   • Save the file.
   • The extension server will automatically update, and your extension should refresh in the browser.

Releasing Your Extension

Once your extension is ready for the rest of your team or collaborators, it's time to release it.

1. Build & Release:

   • Run the following command in your terminal:

   block release

   This will upload and store your code on Airtable's servers.

2. Refresh Base:

   • Refresh your Airtable base in the browser.
   • Your extension will still be present even if the development server is off.

3. Collaborator Access:

   • Invite collaborators to your base to see and interact with your extension.
