Creating a Typescript interface for a sophisticated response fetched from a REST API

I'm currently struggling with how to manage the response from VSTS API in typescript.

Is there a way to handle this interface effectively?

export interface Fields {
'System.AreaPath': any;

'System.TeamProject': string;
'System.IterationPath': string;
'System.WorkItemType': string;
'System.State': string;
'System.Reason': string;
'System.AssignedTo': string;
'System.CreatedDate': Date;
'System.CreatedBy': string;
'System.ChangedDate': Date;
'System.ChangedBy': string;
'System.Title': string;
'Microsoft.VSTS.Feedback.ApplicationType': string;
'System.Description': string;
'System.History': string;
'Microsoft.VSTS.Feedback.ApplicationStartInformation': string;
'Microsoft.VSTS.Feedback.ApplicationLaunchInstructions': string;
}

Within my code, I am attempting to iterate through the Fields (workItems === Fields)


<tbody>
        <tr *ngFor="let workitem of workItems">
          <!-- *ngFor="let field of workitems.fields" -->
          <td>{{workitem.fields.System.AreaPath}} << THIS IS NOT ALLOWED</td>
        </tr>

      </tbody>

Does anyone have a brilliant idea on how to solve this issue?

Answer №1

{{ workitem.fields['System.AreaPath'] }}

Is this functionality functional?

Answer №2

Initially, it is not feasible to employ ngFor on an object.

Furthermore, assuming workItems belongs to the Fields category, there is no requirement for a loop in order to exhibit one of its characteristics. The only necessity, identical to JavaScript or TypeScript, would be

workItems['System.AreaPath']

Answer №3

Big shoutout to @elzoy and @JB Nizet for helping me figure out that ['System.AreaPath'] is the key I needed when dealing with complex properties on interfaces. Wish TypeScript had some decorators like [JsonProperty] in C#, but this solution works really well.

Thank you so much - I was struggling for hours before your assistance came through. :)


<tbody>
<tr *ngFor="let workitem of workItems">

<td>{{workitem.fields['System.AreaPath']}}</td>
</tr>
</tbody>


export interface Fields {

'System.AreaPath': string;

'System.TeamProject': string;
'System.IterationPath': string;
'System.WorkItemType': string;
'System.State': string;
'System.Reason': string;
'System.AssignedTo': string;
'System.CreatedDate': Date;
'System.CreatedBy': string;
'System.ChangedDate': Date;
'System.ChangedBy': string;
'System.Title': string;
'Microsoft.VSTS.Feedback.ApplicationType': string;
'System.Description': string;
'System.History': string;
'Microsoft.VSTS.Feedback.ApplicationStartInformation': string;
'Microsoft.VSTS.Feedback.ApplicationLaunchInstructions': string;
}

export interface WorkItemFullInformation {
id: number;
rev: number;
fields: Fields;
url: string;

}

export interface FetchWorkItemRootObject {
count: number;
value: WorkItemFullInformation[];

}
