A javascript plugin to add a user feedback form to your website.
You will also need a backend data store. See user-feedback-store.

import userFeedbackForm from '@nhsuk/user-feedback-form';
userFeedbackForm({
cssSelector: "#my-div-id",
formEndpoint: "https://example.com/my-api-endpoint/",
enableTextResponse: false,
});If you do not have a node-based javascript frontend build, you can use the minified javascript distribution.
The latest javascript file can be found in github releases https://github.com/nhsuk/user-feedback-form/releases
<!-- in the html <head> -->
<script src="./user-feedback-form.min.js" defer></script>
...
<!-- where you want the form to appear -->
<div id="nhsuk-user-feedback-form" data-form-endpoint="https://example.com/endpoint/"></div>data-form-endpoint - (required) An HTTP data store endpoint to POST data to. Include the trailing slash. The endpoint setting should probably be this:

An onFeedback event is emitted when the user gives satisfied or unsatisfied feedback by clicking on the yes or no buttons.
You can listen to this event to trigger custom javascript code.
// Listen to the event on the container div
document.querySelector("#nhsuk-user-feedback-form").addEventListener('onFeedback', (event) => {
// custom code using the boolean `isSatisfied` value.
console.log(event.detail.isSatisfied)
});Run npm install followed by npm start to start a development server. A test site will be available at http://localhost:8080/tests/example/
For now, this app is very simple, so we don't use any libraries like Vue or React.
The App class in src/index.js represents the app as a whole.
Each screen has it's own class which can be instantiated and rendered with the render method when the screen should be displayed.
The screen classes are responsible for screen-level interactions such as rendering, attaching event listeners and input validation.
Run npm run lint to run eslint code linting.
Run npm test to run all tests.
