@quantojs/anything

One quanto codec that reads anything the first-party packages can: dates, times, money, every quantity, dimensions, coordinates, ring and shoe sizes, CSS colors, pitches, numbers, ratios and odds, ranges of them, infinities, and all of it approximate. It's the big field on quanto's site, as a package.

import { anything } from '@quantojs/anything';
import { phoneNumber } from '@quantojs/anything/phone';

anything().parse('24x36in');      // { value: { codec: 'dimensions(length)', value: [{ value: 24, unit: 'in' }, …] }, approximate: false }
anything().parse('about 6 ft');   // { value: { codec: 'length', value: { value: 6, unit: 'ft' } }, approximate: true }
anything().parse('$10-20k');      // { value: { codec: 'range(money)', value: { start: …, end: … } }, approximate: false }
anything().parse('next fri');     // { value: { codec: 'date', value: '2026-10-02' }, approximate: false }

const withPhones = anything({ include: [phoneNumber()] });
withPhones.parse('(415) 555-2671');   // { value: { codec: 'phoneNumber', value: '+14155552671' }, approximate: false }

• The value is tagged with the id of the codec that read it: switch on value.codec to know what value.value is. format prints it with that codec.
• The order settles conflicts. The first codec that reads the text wins, and the others' readings are its alternatives. Dates and times come first, then dimensions, length, mass, duration and temperature, money, pitch, the other quantities, coordinates, sizes and CSS colors, then plain numbers, ratios and odds, then ranges. So 24 × 36 in is dimensions, 455hz a pitch, 3 g grams, 11/4 a date, 25 bps a data rate, US 10 a ring size, 2700 K a temperature (with the color temperature as an alternative) and 70 a number. CSS colors read without bare, so bad and 0 170 255 aren't colors. A trailing odds claims any of them for odds: 11/4 odds, 70 odds. The fixtures pin every conflict.
• Infinities are tagged with the member their unit or kind names: unlimited GB is { codec: 'dataSize', value: { infinite: 1, unit: 'GB' } }, infinite length is { codec: 'length', value: { infinite: 1 } }, and a bare ∞ is { codec: 'infinite', value: { infinite: 1 } }. Test value.value with isInfinite from quanto.
• Phone numbers are opt-in with include, since libphonenumber-js's metadata is about 80 kB. phoneNumber is re-exported from @quantojs/anything/phone for convenience, on its own subpath so the main entry never brings the metadata, whatever the bundler. To load it later, await import('@quantojs/anything/phone') and build the codec again with it.
• include takes any codecs: they're read after the built-in ones and before the catch-alls (numbers, ratios, odds).
• names adds month and weekday names for dates, as date({ names }) does.
• Failures are tidied: the first issue of each informative code (unknown_unit, ambiguous, …), or one unparseable.
• Not included: addresses (an external codec), percent (proportion reads %), text and time signatures (6/8 is a date).
• Still evolving. The order changes as codecs are added, so what a text reads as can change between releases.

quanto is a peer dependency.
