The error message in Angular4 displays code that does not match the intended code to be executed

I am currently developing an application for a website that will handle simplex algorithms. One of my current tasks is to implement a feature that allows the user to input the number of coefficients and constraints, give them custom names, and then have the application generate the necessary UI elements based on this input. The relevant portion of code appears to be in the app.component.ts file:

import { Component } from '@angular/core';

[...]

export class UIComponent {
  id: 1;
  name: string;
  value: number;
  type: string;
}

//* Sample data */
const UICOMPONENTS: UIComponent[] = [
  { id: 1, name: 'coefficient1', value: 4, type: '1dslide' },
  { id: 2, name: 'constraint1', value: 2, type: '2dslide' },
  { id: 3, name: 'min_max', value: 0, type: 'switch' },
  { id: 4, name: 'profit', value: 100, type: 'num_output' }
];

[...]

export class AppComponent {
  title = 'SimutronX';
  uicomponents = UICOMPONENTS;
  [...]
}

When I run the app, I encounter an error message stating:

Failed to compile.

/root/simutronx/simutron-app/src/app/app.component.ts (18,49): ',' expected.

This error specifically points to the line:

{ id: 2, name: 'constraint1', value: 2, type: '2dslide' },

The issue seems to be with the 2 in 2dslide. The error message also includes additional information:

./src/app/app.component.ts
Module parse failed: /root/simutronx/simutron-app/node_modules/@ngtools/webpack/src/index.js!/root/simutronx/simutron-app/src/app/app.component.ts Unexpected token (22:85)
You may need an appropriate loader to handle this file type.
| var UICOMPONENTS = [
|     { id: 1, name: 'coefficient1', value: 4, type: '1dslide' },
|     { id: 2, name: 'constraint1, value: 2, type: ', 2: dslide, ' },: { id: 3, name: 'min_max', value: 0, type: 'switch' }, },
|     { id: 4, name: 'profit', value: 100, type: 'num_output' }
| ];

This error message is puzzling because the code itself does not match what's being reported. Can someone help me understand what could be causing this?

Answer №1

You are encountering an issue with the UIComponent type:

export class UIComponent {
  id: number; //FIX THIS
  name: string;
  value: number;
  type: string;
}
