• Turso Starter Kit

The Turso Starter Kit accelerates the integration of a Turso database, created using Turso’s LibSQL SDK, into an edge function. It also provides an interface to easily create, update, and delete items in your database.

This template uses LibSQL 0.5.3.

To use this template, you must:

• Create a Turso account.
• Install the Turso CLI.
• Create a database with a table called posts, with the fields id and message, as explained in the next section.
• Generate your GitHub personal token.

You must also activate:

To enable them:

1. Access Azion Console > Account menu.
2. Select the Billing & Subscriptions option.
3. Select the Subscriptions tab.
4. Activate the switch for each module.

Assuming you’ve already created a Turso account and installed the Turso CLI on your computer, you’ll just need to complete the following steps using a few commands:

• Authenticate your Turso account: turso login
• Create a new database: turso db create
• List your databases: turso db list
  • You’ll obtain the LibSQL URL for your database.
• Create an authorization token to access it: turso db tokens create [your database name]
  • In this case, the name for your database should be posts.
  • Remember to save it in a secure place.
• Open the shell interface of your database: turso db shell [your database name]
• Create the table that’ll be used by this template using SQL:

CREATE TABLE posts (
  id INTEGER PRIMARY KEY,
  message varchar(140)
);
.quit

If you’ve run all the commands correctly, you’ll be able to use the URL/token during the launch process of this template.

To start using this template, access Azion Console and click the + Create button on the homepage.

This will open a modal where you can select Templates > Turso Starter Kit card.

On the template’s page, click the Settings tab to open the configuration form and provide the information to configure your application.

Fields identified with an asterisk are mandatory.

• Application Name *: the name of your edge application on Azion.
• GitHub Personal Token *: your GitHub personal token.
• Turso Database LibSQL URL *: the LibSQL URL to connect with your Turso database.
• Turso Database Token *: the authorization token to access your Turso database.

After completing all the information, click the Next button, located in the bottom-right corner. This will start the deployment process.

You can follow the deployment process through a window showing off the logs. When it’s complete, the deployment page appears, confirming the edge application has been successfully created.

This page shows information about the application and some options to continue your journey.

Now you can manage and adjust the settings through Azion Console.

This template deploys a basic edge application with a domain to access the interface and an edge function including a CRUD query example. Additionally, it creates an instance and a Default Rule to execute the function, as well as sets new environment variables for your Turso credentials.

It also creates a new GitHub repository, including a GitHub Action to enable a continuous development workflow and keep your application up to date.

You can use the Azion domain to access the application through the browser, as explained in the deployment section, and interact with the database through the static interface that was created.

By using this interface, you’re able to create, retrieve, update, and delete items in your posts database, which is now linked to this new application. To do so, the interface provides an input area and icon buttons to manage your data as required.

All changes will be reflected on your application and your Turso database as well.

Considering that this initial setup may not be optimal for your specific edge application, all settings can be customized any time you need through Azion Console.

To manage and edit your edge application’s settings, proceed as follows:

1. Access Azion Console > Edge Application.

• You’ll be redirected to the Edge Application page. It lists all the edge applications you’ve created.

2. Select the edge application related to this template.

• The list is organized alphabetically. You can also use the search bar located in the upper-left corner of the list; currently, it filters only by Application Name.

After selecting the edge application you’ll work on, you’ll be directed to a page containing all the settings you can configure.

Once the template is deployed, you can also edit and update your args and code, as well as implement a continuous deployment workflow. However, you’ll need first to declare secrets on your project’s GitHub repository to complete the second build with the changes. When the second build is completed, you’ll be able to manage your project with a continuous deployment workflow and edit the args as desired.

To do so, open your new [NAME] repository on GitHub. Then, go to Settings > Secrets and variables > Action to add your variables, following these instructions:

1. Add the Azion personal token to the secrets:

• Read how to generate an Azion personal token in the documentation.

    AZION_PERSONAL_TOKEN=<value>

2. Add the environments for use in the action workflow in the main.yml file, included in the .github/workflows folder of your repository:

  - name: edge-...
    id: azion_edge
    ...
    with:
        ....
        azionPersonalToken: ${{ secrets.AZION_PERSONAL_TOKEN }}
        ....

3. Open a pull request to merge the changes to the main branch and start the automatic deployment.

Now, your project is ready to work with a continuous deployment workflow, updating instantly any changes in the application or the repository.

The edge application created during the deployment has an assigned Azion domain to make it accessible through the browser. The domain has the following format: xxxxxxxxxx.map.azionedge.net/. However, you can add a custom domain for users to access your edge application through it.
