Build Vercel-Connected Web Apps in Servoy

Servoy is a rapid application development and deployment platform. When paired with the CData API Driver for JDBC, users can build Vercel-connected apps that work with live Vercel data. This article describes how to connect to Vercel from Servoy and build a simple web app to display and search Vercel data.

With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live Vercel data. When you issue complex SQL queries to Vercel, the driver pushes supported SQL operations, like filters and aggregations, directly to Vercel and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations). Its built-in dynamic metadata querying lets you work with Vercel data using native data types.

Connect to Vercel in Servoy Developer

To build Vercel-connected apps, you need to first create a data provider in Servoy Developer using the CData API Driver for JDBC.

1. Install the JDBC Driver.
2. Copy the JDBC Driver JAR file. (cdata.jdbc.api.jar) to the /application_server/drivers/ directory in the installation directory for Servoy.
3. Open Servoy Developer.
4. In the Solution Explorer, right-click Database Server (under Resources) and choose "Connect to existing database" -> "empty."
   1. Name the server.
   2. Click to show the advanced server settings.

      • Set the URL, for example: jdbc:api:Profile=C:\profiles\Vercel.apip;AuthScheme=APIKey;APIKey=your_access_token;

        Built-In Connection String Designer

        For assistance in constructing the JDBC URL, use the connection string designer built into the Vercel JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

        				java -jar cdata.jdbc.api.jar
        				

        Fill in the connection properties and copy the connection string to the clipboard.

        Using API Key Authentication

        Vercel uses Bearer token authentication. You can use either a personal access token or an OAuth access token as the API key.

        To obtain a personal access token:

        1. Log into your Vercel account at https://vercel.com/
        2. Navigate to Account Settings > Tokens.
        3. Click Create Token, enter a name and expiration, and click Create.
        4. Copy the generated token (it will only be shown once).

        After obtaining your token, set the following connection properties:

        • AuthScheme: Set this to APIKey.
        • APIKey: Set this to your Vercel personal access token or OAuth access token.

        Example Connection String

        Profile=C:\profiles\Vercel.apip;AuthScheme=APIKey;APIKey=your_access_token;
        

        Working with Teams

        Many Vercel resources are scoped to a team. To scope all requests to a specific team, set the TeamId connection property to your team's ID. You can find your team ID by querying the Teams table or from the Vercel dashboard. Alternatively, you can specify TeamId in your SQL queries using the WHERE clause where supported.

        Connecting to Vercel

        Once the authentication is configured, you can connect to Vercel and query data from any of the available tables such as Projects, Deployments, Teams, and Domains.

Build a Vercel-Connected Web App

Once you have configured the connection to Vercel in the Servoy Developer resources, you are ready to build apps with access to live Vercel data.

Create a New Solution

1. In the Server Explorer, right-click "All solutions" and select "Create new solution."
2. Name the solution.
3. Select the checkbox to include the "search" module.
4. Click "Finish."

Create a New Form

Right-click "Forms" and select "Create new form."

1. Name the form.
2. Select a Datasource.
3. Set the type (e.g., Simple) and click "Finish."

Add a Data Grid to the Form

1. Drag a Data Grid component (from Servoy NG-Grids) onto the form.

2. Drag a column component onto the Data Grid and set the "dataprovider" property for each column component to a column from the Vercel "table" (e.g., from the User table).

   Continue adding columns as desired.

Add Searching to the App

Note that the "svySearch" extension is required to add search functionality (included by default when you create a new solution). If you did not add the extension when you created the solution or you are modifying an existing solution, you can add the search module by right-clicking Modules (in the solution) and selecting "Add Module." Select "svySearch" and click "OK."

1. Drag a Text Field component onto the Form.
2. Right-click the Form and select "Open in Script Editor."
3. Create a new variable (JavaScript) to hold the search value:

   var searchText = '';
   

4. Back on the Form, in the Text Field properties:
   1. Set the "dataprovider" property to the Form variable you just created.
   2. Double-click to add a method for the onAction event.
   3. Click to create the method in "Form," name the method (e.g., onEnter), and click "Create private."
   4. Click "OK & Show."
5. Add the following JavaScript to the JavaScript file to use the Servoy framework to implement searching bound data based on the text in the Text Field:

   var search = scopes.svySearch.createSimpleSearch(foundset).setSearchText(searchText);
   search.setSearchAllColumns();
   search.loadRecords(foundset);
   

Save and Launch the App

Save the form and JavaScript file, then click Run -> Launch NGClient to start the web app.
