Examples

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>

import SlFormatBytes from '@shoelace-style/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>

import SlFormatBytes from '@shoelace-style/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>

import SlFormatBytes from '@shoelace-style/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" />
