Connect to Miro 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 API Driver for ADO.NET can be used with standard ADO.NET interfaces, such as LINQ and Entity Framework, to interact with live Miro 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 Miro using standard SQL queries.

Install the CData API Driver for ADO.NET

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

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

Create a Miro-Connected Blazor App

Start by creating a Blazor project that references the CData API Driver for ADO.NET

1. Create a Blazor project on Visual Studio.

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.API.dll, typically located at C:\Program Files\CData\CData API Driver for ADO.NET\lib etstandard2.0).

SELECT Miro Data from the Blazor App

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

   Using API Key Authentication

   Miro uses API Key authentication with an access token. To generate an access token:

   1. Log in to your Miro account
   2. Navigate to Settings > Your apps
   3. Click "Create new app" or select an existing app
   4. Configure the required permissions (e.g., boards:read, teams:read)
   5. Install the app and generate an access token
   6. Copy the generated access token (it will only be shown once)

   After obtaining your access token, set the following connection properties:

   • AuthScheme: Set this to APIKey.
   • APIKey: Set this to your access token.

   Connecting to Miro

   Once the authentication is configured, you can connect to Miro and query data from any of the available tables such as Boards, Items, Teams, Organizations, and more.

   For example: Profile=C:\profiles\Miro.apip;AuthScheme=APIKey;ProfileSettings='APIKey=your_access_token';

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

         @page "/"
         @using System.Data;
         @using System.Data.CData.API;
         
         <h1>Hello, world!</h1>
         
         Welcome to your Data app.
         
         <div class="row">
             <div class="col-12">
         
                 @using (APIConnection connection = new APIConnection(
                   "Profile=C:\profiles\Miro.apip;AuthScheme=APIKey;ProfileSettings='APIKey=your_access_token';"))
                 {
                     var sql = "SELECT ,  FROM Boards WHERE BoardId = '3074457361234567890'";
                     var results = new DataTable();
         
                     APIDataAdapter dataAdapter = new APIDataAdapter(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 Miro data as an HTML table in the Blazor app.

   At this point, you have a Miro-connected Blazor app, capable of working with live Miro data just like you would work with a SQL Server instance. Download a free, 30-day trial and start working with live Miro data in your Blazor apps today.
