toast-msg component

This is a toast-msg component: developers could create several toast messages. They will appear stacked on top of each other, and they will disappear automatically after a certain amount of time. It is a standard custom web component written in pure vanilla JS, so it could be used in any framework.

With the package you will find a complete functional example.html

Usage:

Import the class of this component ToastMsg, then use its constructor to create a toast message: const toast = new ToastMsg(content, msgTime, rtl); where:

• content: represents the content of the toast message.
  • could be a boolean type: if true => , if false =>
  • could be undefined (you do not pass anything): the same as if you pass boolean true
  • could be a string: you pass the message that you want to show.
• msgTime: the toast message, when appended to the document, will slid-in in 500 ms, will be shown for msgTime in ms (no-motion time), finally will slide-out in 500 ms:
  • could be a number to represent the no-motion time in ms.
  • could be undefined: in this case the no-motion time depends on the content of the message, and will be calculated according to this formula: min(5000, max(500, 60 * content.length)) which means that the no-motion time will be proportional to the length of the message, but should never be outside the range [500, 5000] ms.
• rtl: Right-to-Left or Left-to-Right.
  • could be a string: rtl => the component will behave in a way compatible with Right-to-Left hand writing systems; it will slide-in from the right-hand side of the screen. For any other string value, the component will behave in a way compatible with Left-to-Right hand writing systems: it will slide-in from the left-hand side of the screen.
  • could be a boolean type: if true => as if passed the string rtl, if false => as if passed the string ltr.
  • could be undefined (you do not pass anything): the same as if you pass boolean false

  import ToastMsg from "./toast-msg.js";
  
  document.body.appendChild(new ToastMsg());
  document.body.appendChild(new ToastMsg(false));
  document.body.appendChild(new ToastMsg(true, 1000));
  document.body.appendChild(new ToastMsg("any message"));
  document.body.appendChild(new ToastMsg("this message will appear from the right-hand side of the screen", "", "rtl"));

Styling:

The component is simply a standard div element and you can reach it through ::part(container)

::part(container) { background-color: lightgray; }
