TL;DR

I looked and looked for days (seriously) for a simple Vuetify (or Vue) component that only accepted floating point numbers of a specified range before and/or after the decimal.

<input type="number"...> (via <v-text-field type="number"...>) seems to:

1. not allow controlling the selection/cursor:
   https://developer.mozilla.org/en-US/docs/Web/API/HTMLInputElement/setSelectionRange
   This blocks the ability to control the number range before and/or after the decimal.
2. automatically place "step" arrows on the right edge
3. be left justified
4. ignore max/min/maxlength properties
5. (I am sure I am missing a few other limitations/problems)

This results in a control unusable for limiting floating point input.

input type="text" pattern="[0-9\.]" only validates the input when it is submitted.

There seems to be a crazy [legacy?] history about input's limitations and why it is so bad.

To make things even weirder, Vuetify rejected even rejected a PR to do this:

• https://github.com/vuetifyjs/vuetify/pull/2235

3rd Party:

• https://github.com/vuejs-tips/v-money
  • https://codesandbox.io/s/38r6wq4mjp
    Has a blocking bug:

    https://codepen.io/paulpv/pen/oqMeXd
• https://vuejs-tips.github.io/vue-the-mask/
  Recommends using [above] v-money
  Problem is that "mask=###.##" doesn't allow the user to enter "0.1"! They must enter "000.10".

None of these seem to "just work" without some annoying side-effects.

After days of searching I finally gave up looking for an existing component and decided to learn a bit more Vue & Vuetify and write my own.

If you can find an existing component that does precisely what this component does, or better, PLEASE TELL ME ABOUT IT!

Originally created via:
https://github.com/vue-land/create-vue-component

Another option was to try:
https://github.com/NetanelBasal/vue-generate-component
But, I didn't like that template's generated output.
(However, I might revisit this with what I have learned since.)

I tried using:
https://github.com/vuejs-tips/vue-component-template
But, that project is over a year old and relys on vue build which was removed 2017/10/01.

I would prefer to base this repo off of a webpack[-simple] template, but I have been unable to find examples of how to do this or get this to work the way that I want.
I am all ears if you have any recommendations/suggestions on how to better package this component.
