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

Getting Started

---

Install the CData ADO.NET Provider for Jira

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

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

Create a Jira-Connected Blazor App

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

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.JIRA.dll, typically located at C:\Program Files\CData\CData ADO.NET Provider for Jira\lib etstandard2.0).

SELECT Jira Data from the Blazor App

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

   To connect to JIRA, provide the User and Password. Additionally, provide the Url; for example, https://yoursitename.atlassian.net.

   For example: User=admin;Password=123abc;Url=https://yoursitename.atlassian.net;

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

         @page "/"
         @using System.Data;
         @using System.Data.CData.JIRA;
         
         <h1>Hello, world!</h1>
         
         Welcome to your Data app.
         
         <div class="row">
             <div class="col-12">
         
                 @using (JIRAConnection connection = new JIRAConnection(
                   "User=admin;Password=123abc;Url=https://yoursitename.atlassian.net;"))
                 {
                     var sql = "SELECT Projects.LeadName, Issues.Summary FROM Projects, Issues WHERE Projects.Id=Issues.ProjectId";
                     var results = new DataTable();
         
                     JIRADataAdapter dataAdapter = new JIRADataAdapter(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 Jira data as an HTML table in the Blazor app.

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