Usage

sion.js has no dependency so you can simply put it anywhere handy. It is a ES6 module so you need a faily modern environments.

on browsers

In your JS script:

</script>

You can even directly import from CDN:

<script type="module">
  import {SION} from 'https://cdn.jsdelivr.net/npm/[email protected]/sion.min.js';
</script>

Tree-shaken import is also supported.

import {stringify, parse} from './sion.js';

Besides SION, the trunk, the follow symbols are exported:

• RE_HEXFLOAT: a RegExp that matches hexadecimal floating-point number.
• RE_HEXFLOAT_G: same as RE_HEXFLOAT with a 'g' flag.
• parseHexFloat: parses hexadecimal floating point.
• toHexString: prints number in hexadecimal floating point format.
• stringify: cf. JSON.stringify. stringifies a JS object to a SION string.
• parse: cf. JSON.parse. parses SION string to a JS object.
• version: The version of module.

$ node
> const SION = await import('js-sion');
undefined
> SION

  RE_HEXFLOAT: /([+-]?)0x([0-9A-F]+).?([0-9A-F]*)p([+-]?[0-9]+)/i,
