Building dashboard app in VueJs with ASP.NET core using Embedded SDK

The link has been provided to download the sample application, which demonstrates the dashboard rendering with the list of dashboards available in your Bold BI server and followed by steps to create a new embedding application in the VueJs with ASP.NET Core on your own.

NOTE: The best way to get started would be to read the Getting Started section of the documentation. The Getting Started guide gives you enough information that you need to know before working on the sample.

How to run the sample

Please download the VueJS with ASP.NET Core Application sample.
Here, the VueJS application act as a client, and the ASP.NET Core application act as a server since you need to set the following properties in the App.vue file in the VueJS app as follows.

In the EmbedProperties.cs of the ASP.NET Core application, you need to set the RootUrl, SiteIdentifier, UserEmail, and EmbedSecret properties. Embed Properties in App Component

siteIdentifier	For Bold BI Enterprise edition, it should be like `site/site1.` For Bold BI Cloud, it should be an empty string.
rootUrl	Dashboard Server BI URL (ex: http://localhost:5000/bi, http://demo.boldbi.com/bi)
authorizationUrl	Url of the GetDetails action in the Go application(http://localhost:8086/getDetails).
environment	Your Bold BI application environment. (If Cloud, you should use cloud, if Enterprise, you should use onpremise)
DashboardId	Set the item id of the dashboard to embed from BI server.

Get the item id of the dashboard from the Bold BI server. Please refer to this link and the following screenshot.
Then, run your ASP.NET application and as well as the VueJS App.

The dashboard can be rendered in design mode or created with the following changes in the App.Vue method.

 let dashboard = BoldBI.create({
                serverUrl: rootUrl + siteIdentifier,
                dashboardId: dashboardId,
                embedContainerId: "dashboard",
                embedType: BoldBI.EmbedType.Component,
                environment: environment == "enterprise" ? BoldBI.Environment.Enterprise : BoldBI.Environment.Cloud,
                mode:BoldBI.Mode.Design,
                width: "100%",
                height: window.innerHeight + "px",
                expirationTime: 100000,
                authorizationServer: {
                    url: authorizationUrl
                }
            });
            dashboard.loadDesigner(); 
            console.log(dashboard);

serverUrl	Dashboard Server BI URL (ex: http://localhost:5000/bi/site/site1, http://dashboard.syncfusion.com/bi/site/site1)
dashboardId	Provide the dashboard id of the dashboard you want to embed in view or edit mode. Ignore this property to create new dashboard.
embedContainerId	Container Id in which dashboard renders.It should not contain hypen.
mode	In which mode you want to render dashboard. It can either be 'View' or 'Design' mode.
expirationTime	Set the duration for the token to be alive.
authorizationServer	Url of the 'GetDetails' action in the ASP.NET application.

How this sample works

Based on the dashboardId provided in the App.vue, you will authorize the server by calling the GetEmbedDetails function using the AuthorizeURL(http://localhost:61377/getDetails) with the provided EmbedProperties values.
In the above authorization, the SignatureURL has been generated with the provided EmbedSecret key and embed details, which can be validated in the Bold BI Server API and returns the token. Based on the returned token, the dashboard will start to render.
In theApp.vue, change the dashboard Id of the respective dashboard as you wish to embed.

Steps to create new VueJs with ASP.NET Core application to embed dashboard

Install the nodeJS, using the command prompt and type vue create my-app in desired location to create angular application. Here, my-app is the name of the folder for your application. To run the vue application, change the project folder cd my-app.

Open the App.vue page and refer to the mandatory cdn file in <head> tag using mounted function as follows.

mounted: function() {
var scripts = [
 "https://cdn.jsdelivr.net/npm/vue@2.5.16/dist/vue.js",
 "https://cdnjs.cloudflare.com/ajax/libs/jquery/1.10.2/jquery.min.js",
 "https://cdnjs.cloudflare.com/ajax/libs/jsrender/1.0.0-beta/jsrender.min.js",
 "https://cdnjs.cloudflare.com/ajax/libs/jquery-easing/1.3/jquery.easing.min.js",
 "https://cdn.boldbi.com/embedded-sdk/v5.2.48/embed-js.js",
];
scripts.forEach(script => {
 let tag = document.createElement("script");
 tag.setAttribute("src", script);
 tag.setAttribute("type", "text/javascript");
 tag.setAttribute("defer", "defer");
 tag.async = true;
 document.head.appendChild(tag);
});

Download the VueJs sample and open the VueJs in visual studio code, use the EmbedBIWrapper.js file and import it in App.vue like below.

Set the following mandatory variables to contact the server.

   let rootUrl = "http://localhost:64503/bi";//Dashboard Server BI URL (ex: http://localhost:5000/bi, http://demo.boldbi.com/bi)
   let siteIdentifier = "/site/site1";//For Bold BI Enterprise edition, it should be like site/site1. For Bold BI Cloud, it should be an empty string.
   let dashboardId = "2426b843-bf97-4392-96b1-ef12c007b66f";//Set the item id of the dashboard to embed from BI server.
   let environment = "enterprise";//our Bold BI application environment. (If Cloud, you should use cloud, if  Enterprise, you should use enterprise)
   let authorizationUrl = "http://localhost:61377/getdetails";

To render a dashboard using the EmbedWrapper file, create an instance dashboard and call a method LoadDashboard() as follows.

   let dashboard = BoldBI.create({
                   serverUrl: rootUrl + siteIdentifier,
                   dashboardId: dashboardId,
                   embedContainerId: "dashboard",
                   embedType: BoldBI.EmbedType.Component,
                   environment: environment == "enterprise" ? BoldBI.Environment.Enterprise : BoldBI.Environment.Cloud,
                   width: "100%",
                   height: window.innerHeight + "px",
                   expirationTime: 100000,
                   authorizationServer: {
                       url: authorizationUrl
                   }
               });
               dashboard.loadDashboard(); 
               console.log(dashboard);

To create an ASP.NET core Web application, start Visual Studio and click Create a new project.
Change the project name as you want, then click Create.
Select the Web Application (Model-View-Controller) template, then click Create.

In ASP.NET core, create a model as follows. Under the model folder, create the EmbedProperties.cs class to define the mandatory properties as follows.

   public class EmbedProperties
   {
       public static string UserEmail = "";

       public static string EmbedSecret = "";
   }

In the Controllers\HomeController.cs, define an API GetDetails() which uses the method GetSignatureUrl() to generate the algorithm. In this API, embedQuerString, userEmail and value from the GetSignatureUrl() method is appended as query parameters in the URL to get details of particular dashboard.

 [HttpPost]
   [Route("GetDetails")]
   public string GetDetails([FromBody] object embedQuerString)
   {
       var embedClass = Newtonsoft.Json.JsonConvert.DeserializeObject<EmbedClass>(embedQuerString.ToString());

       var embedQuery = embedClass.embedQuerString;
       // User your user-email as embed_user_email
       embedQuery += "&embed_user_email=" + EmbedProperties.UserEmail;
       var embedDetailsUrl = "/embed/authorize?" + embedQuery + "&embed_signature=" + GetSignatureUrl(embedQuery);

       using (var client = new HttpClient())
       {
           client.BaseAddress = new Uri(embedClass.dashboardServerApiUrl);
           client.DefaultRequestHeaders.Accept.Clear();

           var result = client.GetAsync(embedClass.dashboardServerApiUrl + embedDetailsUrl).Result;
           string resultContent = result.Content.ReadAsStringAsync().Result;
           return resultContent;
       }

   }

   public string GetSignatureUrl(string queryString)
   {
       if (queryString != null)
       {
           var encoding = new System.Text.UTF8Encoding();
           var keyBytes = encoding.GetBytes(EmbedProperties.EmbedSecret);
           var messageBytes = encoding.GetBytes(queryString);
           using (var hmacsha1 = new HMACSHA256(keyBytes))
           {
               var hashMessage = hmacsha1.ComputeHash(messageBytes);
               return Convert.ToBase64String(hashMessage);
           }
       }
       return string.Empty;
   }

Then run the ASP.NET core application. And VueJs by the npm run serve command to render the dashboard.
