Examples

Byte Formatter Basics

The file is in size.

<div class="format-bytes-overview">
  The file is <sl-format-bytes value="1000"></sl-format-bytes> in size. <br /><br />
  <sl-input type="number" value="1000" label="Number to Format" style="max-width: 180px;"></sl-input>
</div>

<script>
  const container = document.querySelector('.format-bytes-overview');
  const formatter = container.querySelector('sl-format-bytes');
  const input = container.querySelector('sl-input');

  input.addEventListener('sl-input', () => (formatter.value = input.value || 0));
</script>
div.format-bytes-overview
  | The file is
  sl-format-bytes value="1000"
  | in size.
  br
  br
  sl-input type="number" value="1000" label="Number to Format" style="max-width: 180px;"

javascript:
  const container = document.querySelector(.format-bytes-overview);
  const formatter = container.querySelector(sl-format-bytes);
  const input = container.querySelector(sl-input);

  input.addEventListener(sl-input, () => (formatter.value = input.value || 0));
import { useState } from 'react';
import SlButton from '@teamshares/shoelace/dist/react/button';
import SlFormatBytes from '@teamshares/shoelace/dist/react/format-bytes';
import SlInput from '@teamshares/shoelace/dist/react/input';

const App = () => {
  const [value, setValue] = useState(1000);

  return (
    <>
      The file is <SlFormatBytes value={value} /> in size.
      <br />
      <br />
      <SlInput
        type="number"
        value={value}
        label="Number to Format"
        style={{ maxWidth: '180px' }}
        onSlInput={event => setValue(event.target.value)}
      />
    </>
  );
};

Formatting Bytes

Set the value attribute to a number to get the value in bytes.




<sl-format-bytes value="12"></sl-format-bytes><br />
<sl-format-bytes value="1200"></sl-format-bytes><br />
<sl-format-bytes value="1200000"></sl-format-bytes><br />
<sl-format-bytes value="1200000000"></sl-format-bytes>
sl-format-bytes value="12"
br
sl-format-bytes value="1200"
br
sl-format-bytes value="1200000"
br
sl-format-bytes value="1200000000"
import SlFormatBytes from '@teamshares/shoelace/dist/react/format-bytes';

const App = () => (
  <>
    <SlFormatBytes value="12" />
    <br />
    <SlFormatBytes value="1200" />
    <br />
    <SlFormatBytes value="1200000" />
    <br />
    <SlFormatBytes value="1200000000" />
  </>
);

Formatting Bits

To get the value in bits, set the unit attribute to bit.




<sl-format-bytes value="12" unit="bit"></sl-format-bytes><br />
<sl-format-bytes value="1200" unit="bit"></sl-format-bytes><br />
<sl-format-bytes value="1200000" unit="bit"></sl-format-bytes><br />
<sl-format-bytes value="1200000000" unit="bit"></sl-format-bytes>
sl-format-bytes value="12" unit="bit"
br
sl-format-bytes value="1200" unit="bit"
br
sl-format-bytes value="1200000" unit="bit"
br
sl-format-bytes value="1200000000" unit="bit"
import SlFormatBytes from '@teamshares/shoelace/dist/react/format-bytes';

const App = () => (
  <>
    <SlFormatBytes value="12" unit="bit" />
    <br />
    <SlFormatBytes value="1200" unit="bit" />
    <br />
    <SlFormatBytes value="1200000" unit="bit" />
    <br />
    <SlFormatBytes value="1200000000" unit="bit" />
  </>
);

Localization

Use the lang attribute to set the number formatting locale.




<sl-format-bytes value="12" lang="de"></sl-format-bytes><br />
<sl-format-bytes value="1200" lang="de"></sl-format-bytes><br />
<sl-format-bytes value="1200000" lang="de"></sl-format-bytes><br />
<sl-format-bytes value="1200000000" lang="de"></sl-format-bytes>
sl-format-bytes value="12" lang="de"
br
sl-format-bytes value="1200" lang="de"
br
sl-format-bytes value="1200000" lang="de"
br
sl-format-bytes value="1200000000" lang="de"
import SlFormatBytes from '@teamshares/shoelace/dist/react/format-bytes';

const App = () => (
  <>
    <SlFormatBytes value="12" lang="de" />
    <br />
    <SlFormatBytes value="1200" lang="de" />
    <br />
    <SlFormatBytes value="1200000" lang="de" />
    <br />
    <SlFormatBytes value="1200000000" lang="de" />
  </>
