Connect to Sentry 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 Sentry 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 Sentry using standard SQL queries.

Install the CData API Driver for ADO.NET

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

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

Create a Sentry-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.
👁 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.API.dll, typically located at C:\Program Files\CData\CData API Driver for ADO.NET\lib etstandard2.0).
👁 Reference ADO.NET for Sentry .dll in the Blazor app.

SELECT Sentry 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

   Sentry uses token-based authentication. To obtain an Auth Token:

   1. Log in to your Sentry account at https://sentry.io
   2. Navigate to Settings > Auth Tokens
   3. Click "Create New Token"
   4. Select the required scopes and click "Create Token"
   5. Copy the generated token (it will only be shown once)

   After obtaining your Auth Token, set the following connection properties:

   • AuthScheme: Set this to APIKey.
   Set the following in the ProfileSettings connection property:
   • APIKey: Set this to your Sentry Auth Token.
   • OrganizationId: Set this to your Sentry organization slug or ID.

   Example Connection String

   Profile=C:\profiles\Sentry.apip;AuthScheme=APIKey;ProfileSettings="APIKey=your_auth_token;OrganizationId=your_org_slug";
   

   Connecting to Sentry

   Once the authentication is configured, you can connect to Sentry and query data from any of the available tables such as Organizations, Projects, Issues, and Events.

   For example: Profile=C:\profiles\Sentry.apip;AuthScheme=APIKey;ProfileSettings="APIKey=your_auth_token;OrganizationId=your_org_slug";

3. The code below creates a simple Blazor app for displaying Sentry data, using standard SQL to query Sentry 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\Sentry.apip;AuthScheme=APIKey;ProfileSettings="APIKey=your_auth_token;OrganizationId=your_org_slug";"))
    {
    var sql = "SELECT , FROM UserOrganizations WHERE = ''";
    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 Sentry data as an HTML table in the Blazor app. 👁 Query Sentry from Blazor app.
   

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