Bold BI Dashboards embedding in React with Go using Embedded SDK

The link has been provided to download he 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 React with Go on your own.

NOTE: The best way to get started would be reading the Getting Started section of the documentation to start using first. 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 React with Go Application.

Here, the React application act as a client and the Go application act as a server since we need to set the following properties in the DashboardListing.js file in the react app as follows. Embed Properties In App Component

siteIdentifier	For Bold BI Enterprise edition, it should be like `site/site1`. For Bold BI Cloud, it should be 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). Learn more about authorize server here.
environment	Your Bold BI application environment. (If Cloud, you should use cloud, if Enterprise, you should use `enterprise`)
DashboardId	Set the item id of the dashboard to embed from BI server.

You could get the item id of the dashboard from the BI server. Please refer to this link and the following screenshot.

In the main.go of the Go application, you need to set the UserEmail and EmbedSecret properties. Embed Properties

UserEmail	UserEmail of the Admin in your Bold BI, which would be used to get the dashboard details from BI server
EmbedSecret	You could get your EmbedSecret key from Embed tab by enabling `Enable embed authentication` in Administration page

Then, run your Go application and as well as the React Application.

The dashboard can be rendered in design mode or created with the following changes in the renderDashboard() method.

renderDashboard() {
      this.dashboard= BoldBI.create({
        serverUrl: rootUrl + siteIdentifier,
        dashboardId: dashboardId,//Provide the item id to render it in the design mode and create a dashboard to remove this property.
        embedContainerId: "dashboard",
        embedType: BoldBI.EmbedType.Component,
        environment: environment,
        mode:BoldBI.Mode.Design,
        width:"100%",
        height: window.innerHeight + 'px',
        expirationTime:100000,
        authorizationServer: {
            url:authorizationUrl
        }
    });

    console.log(this.dashboard);
    this.dashboard.loadDesigner();     
      
    }

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 application.

How this sample works

Based on the dashboardId provided in the DashboardListing.js, you will authorize the server by calling the GetEmbedDetails function using the AuthorizeURL(http://localhost:8086/getDetails) with the provided EmbedProperties values.
In the above authorization, the SignatureUrl has been generated with the provided Embed Secret key and validated the embed details in Bold BI. Once details are validated, the dashboard starts to render.
In the DashboardListing.js, change the dashboard Id of the respective dashboard as you wish to embed.

Steps to create new React with Go application to embed dashboard

Install the nodeJS in application using link.
Create a react application using the command npx create-react-app my-app. Here my-app is the application folder name.
Change the directory by running the command cd my-app.
Create the folder DashboardListing. Under this folder, create the javascript files DashboardListing.js.

In the DashboardListing.js file, include the mandatory files and create a DOM element with the id dashboard to render dashboard in this container. In the componentDidMount(), invoke the renderDashboard() method as follows.

 const siteIdentifier = "site/site1";

 const rootUrl = "http://localhost:51789/bi/";

 const authorizationUrl = "http://localhost:8086/getDetails"

 const environment = "onpremise";

 const dashboardId = "Enter dashboard id here";
 var BoldBiObj;

 class DashboardListing extends React.Component {
   constructor(props){
       super(props);
       this.state = {toke: undefined, items: []};
       this.BoldBiObj = new BoldBI();
   };

   renderDashboard() {
     this.dashboard= BoldBI.create({
       serverUrl: rootUrl + siteIdentifier,
       dashboardId: dashboardId,
       embedContainerId: "dashboard",
       embedType: BoldBI.EmbedType.Component,
       environment: environment,
       width:"100%",
       height: window.innerHeight + 'px',
       expirationTime:100000,
       authorizationServer: {
           url:authorizationUrl
       },
       autoRefreshSettings: {
           enabled: true,
           hourlySchedule: {
               hours: 0,
               minutes: 1,
               seconds: 0
           }

       },
       actionBegin:"emdbedDashboardActionBegin",
       actionComplete:"emdbedDashboardActionComplete"
   });

   console.log(this.dashboard);
   this.dashboard.loadDashboard();     
     
   }

   render() {
     return (
       <div id="DashboardListing">
           <div id="viewer-section">
             <div id="dashboard"></div>
           </div>
       </div>
     );
   }

   componentDidMount() {
     this.renderDashboard();
   }  
 }
 export default DashboardListing;

Run the command npm install.Once completed, run the command npm i @boldbi/boldbi-embedded-sdk. Once completed, import @boldbi/boldbi-embedded-sdk in the DashboardListing.js.
Install the Go application with the link. Install the visual studio code extension as follows.

Create a folder in the desired location, and open it in the visual studio code. Create a file main.go and launch.jsonand include the following code.

 {
   // Use IntelliSense to learn about possible attributes.
   // Hover to view descriptions of existing attributes.
   // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
   "version": "0.2.0",
   "configurations": [
       {
           "name": "Launch",
           "type": "go",
           "request": "launch",
           "mode": "debug",
           "program": "${workspaceRoot}",
           "env": {"FLASH_PORT": 8086},
           "args": [],
           "showLog": true
       }
   ]
 }

In the main.go file, include the following code to contact the BOLD BI server.

  package main

  import (
    "crypto/hmac"
    "crypto/sha256"
    "encoding/base64"
    "encoding/json"
    "io/ioutil"
    "log"
    "net/http"
    "strings"
  )

  //Set EmbedSecret key from Bold BI Server. Please refer this link(https://help.syncfusion.com/bold-bi/on-premise/site-settings/embed-settings)
  var embedSecret = "enter embed secret here"

  //Enter your BoldBI Server credentials.
  var userMail = "enter user email here"

  func main() {
    http.HandleFunc("/getDetails", getEmbedDetails)
    log.Fatal(http.ListenAndServe(":8086", nil))
  }

  func getEmbedDetails(w http.ResponseWriter, r *http.Request) {
    w.Header().Set("Context-Type", "application/x-www-form-urlencoded")
    w.Header().Set("Access-Control-Allow-Origin", "*")
    w.Header().Set("Access-Control-Allow-Methods", "POST")
    w.Header().Set("Access-Control-Allow-Headers", "Content-Type")
    body, err := ioutil.ReadAll(r.Body)
    if err != nil {
      log.Fatalln(err)
    }
    if len(body) > 0 {
      if queryString, err := unmarshal(string(body)); err != nil {
        log.Println("error converting", err)
      } else {
        serverAPIUrl := queryString.(map[string]interface{})["dashboardServerApiUrl"].(string)
        embedQueryString := queryString.(map[string]interface{})["embedQuerString"].(string)
        embedQueryString += "&embed_user_email=" + userMail
        signatureString, err := getSignatureUrl(embedQueryString)
        if err != nil {
          log.Println(err)
        }
        embedDetails := "/embed/authorize?" + embedQueryString + "&embed_signature=" + signatureString
        query := serverAPIUrl + embedDetails
        log.Println(query)
        result, err := http.Get(query)
        if err != nil {
          log.Println(err)
        }
        log.Println(result)
        response, err := ioutil.ReadAll(result.Body)
        if err != nil {
          log.Fatalln(err)
        }
        w.Write(response)
      }
      //w.Write(result.Body)
    }
  }

  func getSignatureUrl(queryData string) (string, error) {
    encoding := ([]byte(embedSecret))
    messageBytes := ([]byte(queryData))
    hmacsha1 := hmac.New(sha256.New, encoding)
    hmacsha1.Write(messageBytes)
    sha := base64.StdEncoding.EncodeToString(hmacsha1.Sum(nil))
    return sha, nil
  }

  func unmarshal(data string) (interface{}, error) {
    var iface interface{}
    decoder := json.NewDecoder(strings.NewReader(data))
    decoder.UseNumber()
    if err := decoder.Decode(&iface); err != nil {
      return nil, err
    }
    return iface, nil
  }

Initialize the variables embedSecret and userMail for authorization purpose.
Initialize the API /getDetails to get the particular dashboard details from the server.
This API uses the method getSignatureUrl() to generate the algorithm. In the getEmbedDetails() API, the embedQuerString,userEmail and value from the GetSignatureUrl() method is appended as query parameters in the URL to get details of particular dashboard.
Run the Go application and run the React application in the visual studio code by the command npm start to render the dashboard.
