ngx-bootstrap-feedback

Overview

This module provides a modal popup (powered by bootstrap) for collecting user feedback.

Features:

• Customizable form body.
• Configurable styles, text, callbacks.
• Optional screenshot taking and / or uploading functionality.
• Configurable allowed image types and size (for uploading).

Heavily inspired by angular-bootstrap-feedback.

Requirements:

"bootstrap": "^3.3.7",`
"@angular/core": "^2.4.0 || ^4.0.0",
"@herbis/ngx-modal": "^0.1.0", // Modal Functionality
"rxjs": "^5.0.1",
"html2canvas": "0.5.0-beta4" // Optional*

You will also need have the following scripts added in your application (.angular-cli.json example):

{
  ...
  "apps": [
    {
        ...
        "styles": [
          "../../../node_modules/bootstrap/dist/css/bootstrap.min.css",
          "../../../node_modules/ngx-bootstrap-feedback/dist/css/feedback-take-screenshot.min.css" // Optional*
        ],
        "scripts": [
          "../../../node_modules/bootstrap/dist/js/bootstrap.min.js",
          "../../../node_modules/html2canvas/dist/html2canvas.min.js" // Optional* 
        ],
        ...
    }
  ]
  ...
}

• Optionals are only required for 'Take Screenshot' feature.

Installation and Usage

Install using NPM

npm install ngx-bootstrap-feedback --save

Import Feedback module in the required module (usually app root module).

import {FeedbackModule} from "ngx-bootstrap-feedback/feedback.module";
import {ModalModule} from "@herbis/ngx-modal";

@NgModule({
  ...
  imports: [
    ...
    FeedbackModule,
    ModalModule,
    ...
  ],
  ...
})
...

See below for available configuration options.

Initialize feedback configuration

...
this.feedbackConfiguration = {
  onCancel: () => this.clearFeedbackFields(),
  onSubmit: (feedback: FeedbackModel) => this.onSubmitFeedback(feedback),
  screenshotOnlyHighlighted: true
};
...

Add selectors to your component template (usually root) and bind configuration to them.

...
<ngx-bootstrap-feedback [configuration]="feedbackConfiguration">
  <!-- Your customizations. -->
  ...
      <!-- Screenshot field (Optional). -->
      <ngx-bootstrap-feedback-screenshot [configuration]="feedbackConfiguration"></ngx-bootstrap-feedback-screenshot>
  ...
</ngx-bootstrap-feedback>
...

<ngx-bootstrap-feedback [configuration]="feedbackConfiguration">
  <!-- Your customizations. -->
  <div class="row">
    <!-- Input fields. -->
    <div class="col-md-6">
      <!-- Subject field. -->
      <div class="row">
