Connect to WooCommerce Data from Blazor Apps

Blazor is a framework for developing modern, client-side web UIs using .NET technology. Instead of coding in JavaScript, developers can use the familiar C# language and .NET libraries to build app UIs.

The CData ADO.NET Provider for WooCommerce can be used with standard ADO.NET interfaces, such as LINQ and Entity Framework, to interact with live WooCommerce data. Since Blazor supports .NET Core, developers can use CData ADO.NET Providers in Blazor apps. In this article, we will guide you to build a simple Blazor app that talks to WooCommerce using standard SQL queries.

Install the CData ADO.NET Provider for WooCommerce

CData ADO.NET Providers allow users to access WooCommerce just like they would access SQL Server, using simple SQL queries.

Install the WooCommerce ADO.NET Data Provider from the CData website or from NuGet. Search NuGet for "WooCommerce ADO.NET Data Provider."

Create a WooCommerce-Connected Blazor App

Start by creating a Blazor project that references the CData ADO.NET Provider for WooCommerce

1. Create a Blazor project on Visual Studio.
👁 Create a Blazor app project.

2. From the Solution Explorer, right click Dependencies, then click Add Project Reference.
3. In the Reference Manager, click the Browse button, and choose the .dll file of the installed ADO.NET Provider (e.g. System.Data.CData.WooCommerce.dll, typically located at C:\Program Files\CData\CData ADO.NET Provider for WooCommerce\lib etstandard2.0).
👁 Reference ADO.NET for WooCommerce .dll in the Blazor app.

SELECT WooCommerce Data from the Blazor App

1. Open the Index.razor file from the Project page.
2. In a WooCommerceConnection object, set the connection string:

   WooCommerce supports the following authentication methods: one-legged OAuth1.0 Authentication and standard OAuth2.0 Authentication.

   Connecting using one-legged OAuth 1.0 Authentication

   Specify the following properties (NOTE: the below credentials are generated from WooCommerce settings page and should not be confused with the credentials generated by using WordPress OAuth2.0 plugin):

   • ConsumerKey
   • ConsumerSecret

   Connecting using WordPress OAuth 2.0 Authentication

   After having configured the

   • OAuthClientId
   • OAuthClientSecret
   • CallbackURL
   • InitiateOAuth - Set this to either GETANDREFRESH or REFRESH

   In either case, set the Url property to the URL of the WooCommerce instance.

   For example: Url=https://example.com/; ConsumerKey=ck_ec52c76185c088ecaa3145287c8acba55a6f59ad; ConsumerSecret=cs_9fde14bf57126156701a7563fc87575713c355e5;InitiateOAuth=GETANDREFRESH;

3. The code below creates a simple Blazor app for displaying WooCommerce data, using standard SQL to query WooCommerce just like SQL Server.

    @page "/"
    @using System.Data;
    @using System.Data.CData.WooCommerce;
    
    <h1>Hello, world!</h1>
    
    Welcome to your Data app.
    
    <div class="row">
    <div class="col-12">
    
    @using (WooCommerceConnection connection = new WooCommerceConnection(
    "Url=https://example.com/; ConsumerKey=ck_ec52c76185c088ecaa3145287c8acba55a6f59ad; ConsumerSecret=cs_9fde14bf57126156701a7563fc87575713c355e5;InitiateOAuth=GETANDREFRESH;"))
    {
    var sql = "SELECT ParentId, Total FROM Orders WHERE ParentId = '3'";
    var results = new DataTable();
    
    WooCommerceDataAdapter dataAdapter = new WooCommerceDataAdapter(sql, connection);
    dataAdapter.Fill(results);
    
    <table class="table table-bordered">
    <thead class="thead-light">
    <tr>
    @foreach (DataColumn item in results.Rows[0].Table.Columns)
    {
    <th scope="col">@item.ColumnName</th>
    }
    </tr>
    </thead>
    <tbody>
    @foreach (DataRow row in results.Rows)
    {
    <tr>
    @foreach (var column in row.ItemArray)
    {
    <td>@column.ToString()</td>
    }
    </tr>
    }
    </tbody>
    </table>
    }
    </div>
    </div>
    

4. Rebuild and run the project. The ADO.NET Provider renders WooCommerce data as an HTML table in the Blazor app. 👁 Query WooCommerce from Blazor app.
