Getting Started with Congree and Angular

Introduction

This document is itended to give some ideas and code snippets to allow for an easier integration of Congree's features in any application based on Angular. The code snippets shown in this document are based on Angular 7 and higher. 

It is not the intention of this document to provide a full-blown tutorial on Angular development but rather to give some ideas and hints on how to integrate Congree into an Angular app.

The entire functionality is being encapsulated into a single service that can be injected into any Angular component. It provides a hig-level API hiding the complexity of Congree's REST API.

Authentication

The preferred authentication method is TrustCMS. The usage is show in the code below. To be able to use this authentication method you have to make sure that you configure Congree to allow for TrustCMS authentication. Please refer to the Integration Guide and the User Rights settings in the official manuals.

import { Injectable } from '@angular/core';
import { HttpClient, HttpHeaders, HttpParams , HttpResponse} from '@angular/common/http';


@Injectable({
  providedIn: 'root'
})

@Injectable()
export class CongreeService {


  authUrl = '/congreeidentityserver/connect/token';

  constructor(private http: HttpClient) { }

  init(){}
  

 public GetToken(serverUrl: string, username: string, password: string) {

    let headers = new HttpHeaders();
    headers = headers.set('content-type', 'application/x-www-form-urlencoded');

    let params = new HttpParams().set('grant_type', 'password');
    params = params.append('congree_auth_type', 'trustcms');
    params = params.append('username', username);
    params = params.append('password', password);
    params = params.append('scope', 'webApi');
    params = params.append('client_id', 'CongreeWebAPI');

    return this.http.post(serverUrl + this.authUrl, params, this.getAuthHeaders());

  }
  
    return token;
  }

  private getArgHeaders(): any {
    const httpOptions = {
      headers: new HttpHeaders({
        'Content-Type': 'application/x-www-form-urlencoded;charset=UTF-8'
      })
    };
    return httpOptions;
}
}



The following listing demonstrates how this service can be injected into a component. It assumes that the corresponding HTML file contains a button firing the event 'click'.

import { Component } from '@angular/core';
import * as ClassicEditor from '@ckeditor/ckeditor5-build-classic';

import { CongreeService } from '../services/congree.service';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  public Editor = ClassicEditor;
  title = 'CongreeAngularApp';


  constructor(private congreeService: CongreeService){}

 connect() {

    this.congreeService.GetToken('http://WIN-KI2KQ6TURVN', 'UserOperator', '""').subscribe((res) => {
     
      this.token = res['access_token'];
      this.getRules();
    });


  };


}


The parameters in line 20 are hard-coded. I a real-life they will be based on the user's credential and the actual server URL. Congree's REST API returns the result as an observable. The format is a JSON object like shown below. Line 20 in the code above shows how to access the returned token.

{
    "access_token": "eyJhbGciOiJSUzI1NiIsImtpZCI6ImE2MmJlNGQyNzE1MzAwN2I3Mjk2MTFkYjNiYTI1Y2IzIiwidHlwIjoiSldUIn0.eyJuYmYiOjE1Nzc2OTMwMDksImV4cCI6MTU3NzY5NjYwOSwiaXNzIjoiaHR0cDovL3dpbi1raTJrcTZ0dXJ2bi9jb25ncmVlaWRlbnRpdHlzZXJ2ZXIiLCJhdWQiOlsiaHR0cDovL3dpbi1raTJrcTZ0dXJ2bi9jb25ncmVlaWRlbnRpdHlzZXJ2ZXIvcmVzb3VyY2VzIiwiV2ViQXBpIl0sImNsaWVudF9pZCI6IkNvbmdyZWVXZWJBUEkiLCJzdWIiOiIyNzFhNjUyMy1kOWMwLTRjMzYtOWYzNS0xZjViNmUyOGM2MTEiLCJhdXRoX3RpbWUiOjE1Nzc2OTMwMDksImlkcCI6ImxvY2FsIiwibmFtZSI6IlVzZXJPcGVyYXRvciIsInNjb3BlIjpbIndlYkFwaSJdLCJhbXIiOlsicHdkIl19.jwNobmcH6CDWK9I4JZLzw2KC2pU9maJTX2scdrXyIe--yOrSBe81_6-9zz9TOA1yr8oLq0i9ZP7KAyoZiO_nD_YdlJ-Eh9dyXI7gREDzoUd9LOK90Jxq8FksdJkPfWs9dIBw0a1ZOVLZqm8YwHLVUHoROghg5yvwDOHyD_uYMDNn6HrP4ExuPxfT85AJ9c6T1ywY8B0I9GUYASy-I-OkgmTIUxtJFvr1Z2EQ-mC_OkyVchzcj-85wd3fRnA9GWcsPmw83XooyQKWSkPJU16F2C1thb94pKiCuudcDN83ah64Mj3gUXJwK1MYqluQWl6ii8POQ-PSSg0eSI6-uasJMg",
    "expires_in": 3600,
    "token_type": "Bearer"
}

Checking documents

Getting the rules

To be able to do linguistic checks we need to specify the rules the checks are based upon. The rules sets are part of any configuration of the Congree Language Server. To allow the user to select the rules he wants to apply for a check we need to obtain them from the server.

We do this by adding a new method to the service.

public GetDocumentRules(serverUrl: string, token: string) {

    let headers = new HttpHeaders();
    headers = headers.set('Authorization', 'Bearer ' + token);

    return this.http.request('GET', this.serverUrl + this.documentsUrl, { headers });

  }


The argument token is the token we obtained during the authentication process. The expression this.documentsUrl is a reference to a constant defined in the header of the component declaration.

documentsUrl = '/congree/api/Settings/v1/Document/';


The rest of the code is self-explanatory. 

The method GetDocumentRules returns an observable that can be subscribed like shown in the next listing.


getRules() {
   
    this.congreeService.GetDocumentRules('http://WIN-KI2KQ6TURVN', this.token).subscribe((res: []) => {

      this.rules = res;

      this.rules = Array.from(this.rules)
      
    });;

  }

The observable is a list of strings that need to be converted to an array to be useful in UI components like the select element in HTML. The observable may look like this: 

[
    "Congree Standard",
    "Compathy_InDesign_DE",
    "Compathy_InDesign_EN",
    "Compathy_DITA",
    "Compathy_Office_DE",
    "Compathy_Office_EN",
    "Author it",
    "InDesign_Auto",
    "Compathy_DITA_EN",
    "CWI_DE",
    "CWI_EN",
    "STE",
    "Compathy_DITA_FR",
    "Compathy_InDesign_FR",
    "Compathy_Office_FR",
    "CWI_FR",
    "Compathy_DITA_ES",
    "Compathy_Office_ES",
    "Italian",
    "日本の"
]

Checking a document

A document is always a well-formed XML document. Make sure that you obey the constraints that are applicable to well-formed documents. To allow for a check of documents the service will be enhanced by the following method:

public Check(serverUrl: string,text: string, ruleSet: string, token: string) {

    let body = {
      'Xml':  text + , 'options': {
        "includeValidTerms": true,
        "includeReporting": true,
        "extractTermCandidates": true,
        "includeContextMapping": true
      }
    };

    let headers = new HttpHeaders();
    headers = headers.set('Authorization', 'Bearer ' + token);
    headers = headers.append('Content-Type', 'application/json');

    return this.http.post(this.serverUrl + this.checkDocumentUrl + ruleSet, body, { headers: headers });

  }

The parameters of the method Check.

Parameter

Description

serverUrlthe URL of the server where the Congree Api resides
textThe document you are going to check.
ruleSetThe name of the rule set you want to perform the check against.
tokenthe bearer token you have obainted during the authentication process

To make the method more generic you may want to add additional parameters to allow for a flexible configuration of the check and the response object. In the sample code above the configuration is hard-wired. A better approach would be the one shown in the next listing.

public Check(serverUrl: string,text: string, ruleSet: string, token: string, includeValidTerms: boolean, includeReporting: boolean, extractTermCandidates: boolean, includeContextMapping: boolean) {

    let body = {
      'Xml':  text + , 'options': {
        "includeValidTerms": includeReporting,
        "includeReporting": extractTermCandidates,
        "extractTermCandidates": extractTermCandidates,
        "includeContextMapping": includeContextMapping
      }
    };

    let headers = new HttpHeaders();
    headers = headers.set('Authorization', 'Bearer ' + token);
    headers = headers.append('Content-Type', 'application/json');

    return this.http.post(this.serverUrl + this.checkDocumentUrl + ruleSet, body, { headers: headers });

  }

In an Angular component you can now use this method which returns an observable.

check(text) {
    this.congreeService.Check(text, this.selectedRule, this.token).subscribe((res: CongreeCheckResult) => {
    
     console.log(res);
     
    });
  };

Processing the server response

The response is a huge JSON object containing information about each finding as well as information about terms and reporting information. To allow for an easier access to this information in the presentation layer of your application it is a good idea to convert this JSON object into a more convient TypeScript structure. In the sample above the response is being converted into a CongreeCheckResult object representing the JSON structure.

CongreeCheckResult
import { CongreeError } from './CongreeError';
import { CongreeTermCandidate } from './CongreeTermCandidate';
import { CongreeReporting } from './CongreeReporting';

export interface CongreeCheckResult {
    ResultXml: string;
    Errors: CongreeError[];
    TermCandidates: CongreeTermCandidate[];
    Reporting: CongreeReporting;
}


CongreeError
import { CongreeErrorDescription} from '../lib/CongreeErrorDescription';
import { CongreeProposal } from './CongreeProposal';
import { CongreeExplanation } from './CongreeExplanation';

export interface CongreeError{
    Id: string;
    ContextId: string;
    Type: string;
    Descriptions: CongreeErrorDescription[];
    Explanation: CongreeExplanation[];
    ExplanationReWrite: CongreeExplanation[];
    Proposals: CongreeProposal[];
}


CongreeExplanation
export interface CongreeExplanation{
    Type: string;
    Text: string;
}


CongreeErrorDescription
export interface CongreeErrorDescription{
    Code: string;
    Description: string;
    Header: string;
    Instruction: string;
    Explanation: string;
    
}


CongreeProposal
export interface CongreeProposal{
    ConceptId: string;
    Text: string;
    AdditionalInfo: string;
    BaseTermForm: string;
    
}


CongreeReporting
import { CongreeReportingType } from './CongreeReportingType';

export interface CongreeReporting{
   
   TotalCheckedWords: number;
   ReleaseLevel: string;
   RelativeReleaseLevel: string;
   SafeReleaseLevel: string;
   SafeReleaseLevelTitle: string;
   AcceptableReleaseLevel: string;
   AcceptableReleaseLevelTitle: string;
   UnsafeReleaseLevel: string;
   UnsafeReleaseLevelTitle: string;
   ReportingByTypes: CongreeReportingType[];

}


CongreeReportingType
export interface CongreeReportingType{
    
    Type: string;
    ErrorCount: string;
    Severity: string;
    RelativeSeverity: string;
}


CongreeTermCandidate
export interface CongreeTermCandidate{
    Id: string;
    Text: string;
    Context: string;
    IsExist: boolean;
}

Processing the check result

This section details the response object and the way it is rendered in Congree's UIs. The sample is a part of the infamous Compathy Grasp SX document. 

Checking this text results in the following JSON response.

{
    "ResultXml": "<body><p><?cngr-ctx-b 1?>Congratulations on your purchase of the <?cngr-lc-b 0?>ContentGrasp SX<?cngr-lc-e 0?> <?cngr-lc-b 1?>headset<?cngr-lc-e 1?>.

Below you see the rendered presentation of this JSON object.


Finding terms

Finding a term is straightforward. The Angular service gets a new method that does all the job for us:

public SearchTerm(serverUrl: string, term: string, ruleSet: string, token: string){
    let headers = new HttpHeaders();
    headers = headers.set('Authorization', 'Bearer ' + token);

    return this.http.request('GET', this.serverUrl + this.termUrl + 'term=' + term + '&ruleSet=' + ruleSet,  {headers});
  }


ParameterDescription
serverUrlthe URL of the host where the Congree REST API resides
termThe term we are looking for
ruleSetThe rule set we want to use
tokenThe authentication token

The variable termUrl is defined in the header of the service.

termUrl ='/congree/api/Terminology/v1/SearchTerm?';

Getting information on rules sets

A couple of the REST API endpoint expect different parameters that are related to properties of rules sets. In Checking documents we have learned how to retrieve available rule sets and how to use them to perform a document check. However, a rule set is defined by more properties than just the name. 

Let's see how we can retrieve all the properties belonging to a rule set. To do so we enhance the service file by this method:

public GetRuleSetSttings( ruleSet: string, token: string) {
    let headers = new HttpHeaders();
    headers = headers.set('Authorization', 'Bearer ' + token);

    return this.http.request('GET', this.documentSettingsUrl + ruleSet, { headers });
  }

The variable documentSettingsUrl must be defined in the header part of the service.

 documentSettingsUrl = '/congree/api/Settings/v1/Document/';


ParameterDescription
ruleSetThe name of the rule set.
tokenThe bearer token to do the authentication

We can now use this method in one of our Angular components.

getRulesSettings(ruleSet:string){
    this.congreeService.GetRuleSetSttings(ruleSet,this.token).subscribe((res: CongreeRulesSetConfiguration) => {
    
      console.log(res);
      
     });
  }

The response is an obervable that we have to subscribe. To make the access to and the processing of this structure more convenient the sample above use an automatic conversion into a JavaScript structure shown below.

CongreeRulesSetConfiguration
export interface CongreeRulesSetConfiguration{
    LanguageSettings: {
        Language: string
    };
    LinguisticReportingConfiguration:{
        ConfigurationName: string;
        Language: string,
        WordCountFactor: string,
        HighRatingLimit: string,
        HighRatingName: string,
        MediumRatingLimit: string,
        MediumRatingName: string,
        LowRatingLimit: string,
        LowRatingName: string,
        Rules:[
            {
                RuleName:string,
                CategoryType:string,
                Weight:string
            }
        ],
        Categories:[
            {
                ErrorType:string,
                Priority: string
            }
        ]
    };
    ParagraphRecognition:{
        IsAutomaticMode: boolean,
        SymbolsAmountToCheck: string,
        CheckUnitDefinitions:[],
        InlineElementDefinitions:[]
    };
    TermCandidates:{
        Attributes:[{
            AttributeLevel: string,
            Type: string,
            AttributeName: string,
            Values:[],
            AutoValue:string,
            Editable: boolean,
            Mandatory: false
        }
        ]
    }
}

 

If we want to use the language information which is being refered to in the API documentation as culture we can do so like shown below.

getRulesSettings(ruleSet:string){
    this.congreeService.GetRuleSetSttings(ruleSet,this.token).subscribe((res: CongreeRulesSetConfiguration) => {
    
      console.log(res.LanguageSettings.Language);
      
     });
  }
