vue-luxon

DateTime formatting & parsing in Vue using Luxon

https://packages.cblm.nl/vue-luxon

Install

npm install vue-luxon

Setup

import VueLuxon from "vue-luxon";
Vue.use(VueLuxon);

By default, vue-luxon expect the given datetime string to be time zone utc and format iso . The output will be based on the client's locale.

Change the default settings:

Vue.use(VueLuxon, {
    input: {
        zone: "utc",
        format: "iso"
    },
    output: "short"
});

Basic usage

You can use the $luxon method everywhere in your vue app:

this.$luxon("2020-10-05T14:48:00.000Z")
// October 5, 2020

Or use the luxon filter, as shown below:

{{ "2020-10-05T14:48:00.000Z" | luxon }}
// October 5, 2020

You can change the output format:

this.$luxon("2020-10-05T14:48:00.000Z", "dd-MM-yyyy")
// 05-10-2020

this.$luxon("2020-10-05 22:36", "relative")
// 22 days ago

And other settings:

this.$luxon("2020-10-05 22:36", {
    input: { format: "yyyy-MM-dd HH:mm", zone: "Asia/Tokyo" },
    output: "full",
})
// October 5, 2020, 3:36 PM GMT+2

These formats will be in the clients browser language, unless you set a [specific language].

Settings

| prop | options (default) | description | | --------- | -------------------------------------- | ------------------------------------------------------------ | | input | see settings.input | The default input format and zone | | output | see settings.output | The default output format, zone, language, and relative settings | | templates | see templates | Define objects to use as properties |

Default settings

You can change the default settings with the second argument of the Vue.use function.

Vue.use(VueLuxon, {
  templates: {},
    input: {
        zone: "utc",
        format: "iso"
    },
    output: {
        zone: "local",
        format: {
            year: "numeric",
            month: "long",
            day: "numeric"
        },
        locale: null,
        relative: {
            round: true,
            unit: null
        }
    }
});

You can also override the default settings per method/filter easily:

{{ datetimeString | luxon({ settings }) }}
this.$luxon({ settings })

Zone

eg: UTC, America/New_York, Asia/Tokyo, ...

For the systems local zone you use local.

Formats

Input and Output formats

These formats can be used as input.format and output.format

| format | description | in- or output | example | | -------------- | ------------------------------------ | ------------- | --------------------------------- | | sql | SQL dates, times, and datetimes | both | 2017-05-15 09:24:15 | | iso | ISO 8601 date time string | both | 2018-01-06T13:07:04.054 | | rfc2822 | RFC 2822 | both | Tue, 01 Nov 2016 13:23:12 +0630 | | http | HTTP header specs (RFC 850 and 1123) | both | Sun, 06 Nov 1994 08:49:37 GMT | | seconds | Unix timestamp | both | 1542674993 | | millis | Unix timestamp milliseconds | both | 1542674993410 | | tokens | see: tokens | both | yyyy-MM-dd | | templateName | see: Templates | both | |

Output formats

These formats can only be used as output.format

| format | example (with locale en_US) | | ---------------- | ---------------------------------------------------------- | | relative | see: Relative | | short | 10/14/1983, 1:30 PM | | shorts | 10/14/1983, 1:30:23 PM | | med | Oct 14, 1983, 1:30 PM | | meds | Oct 14, 1983, 9:30:33 AM | | full | October 14, 1983, 9:30 AM EDT | | fulls | October 14, 1983, 9:30:33 AM EDT | | huge | Friday, October 14, 1983, 9:30 AM Eastern Daylight Time | | huges | Friday, October 14, 1983, 9:30:33 AM Eastern Daylight Time | | time | 9:30 AM | | times | 09:30:23 AM | | time24 | 09:30 | | time24s | 09:30:23 | | time24longoffset | 09:30:23 Eastern Daylight Time | | date_full | October 14, 1983 | | date_huge | Tuesday, October 14, 1983 | | date_med | Oct 14, 1983 | | date_medd | Fri, Oct 14, 1983 | | date_short | 10/14/1983 |

output.format can also be an object:

// using an object:
format: {
    year: 'numeric',
    month: 'long',
    day: 'numeric'
}

| Property | Possible values | Description | | ------------ | ------------------------------------------- | ---------------------------------------- | | weekday | narrow short long | The representation of the weekday | | era | narrow short long | The representation of the era | | year | numeric 2-digit | The representation of the year | | month | numeric 2-digit narrow short long | The representation of the month | | day | numeric 2-digit | The representation of the day | | hour | numeric 2-digit | The representation of the hour | | minute | numeric 2-digit | The representation of the minute | | second | numeric 2-digit | The representation of the second | | timeZoneName | short long | The representation of the time zone name |

settings.input

object or string

An objectcontaining a zone and format or a string of a template name.

{
	zone: "utc",
	format: "iso"
}

settings.output

object or string

An objectcontaining a zone and format or a string of a template name.

{
    zone: "local",
    format: "short",
    locale: null,
    relative: {} // see settings.relative
}

locale set to null will use the client's locale.

relative Read about the relative format below

settings.output.locale

string

null default value, this will use the client's locale.

Or use a locale tag to set a client location.

Examples:

en: English (primary language).
hi: Hindi (primary language).
de-AT: German as used in Austria (primary language with country code).
zh-Hans-CN: Chinese written in simplified

settings.output.relative

Set the output.format to relative to use the relative format. Or use the luxonRelative filter.

{{ datetime | luxonRelative }}
this.$luxon({ output: { format: "relative" } })

{{ datetime | luxonRelative({ style: "short" }) }}
this.$luxon({ output: { format: "relative", relative: { style: "short" } } })

You can change the behavior with the relative settings object in the output` .

{
    output: {
        format: "relative"
        relative: {
            style: "long",
            unit: null,
            round: true,
            padding: 0
        },
    }
}

| property | description | default | | -------- | ------------------------------------------------------------ | ------- | | style | the style of units, must be "long", "short", or "narrow" | long | | unit | use a specific unit; if omitted, the method will pick the unit. Use one of "years", "quarters", "months", "weeks", "days", "hours", "minutes", or "seconds" | null | | round | whether to round the numbers in the output. | true | | padding | padding in milliseconds. This allows you to round up the result if it fits inside the threshold. Don't use in combination with {round: false} because the decimal output will include the padding. | 0 |

Templates

You can predefine setting templates.

By default there is a server, client and a inputdate template, but you can add your own to the options object.

It's also possible to use a template in a template, as the inputdate uses the client template's zone for example.

templates: {
    server: {
        zone: "utc",
        format: "iso"
    },
    client: {
        zone: "local",
        format: "short"
    },
    inputdate: {
        zone: "client",
        format: "yyyy-MM-dd"
    }
}

There are multiple ways to use a template:

// This will use the templates zone and format
{{ "2020-10-05T14:48:00.000Z" | luxon({ input: "server" }) }}

// This will use the templates zone
{{ "2020-10-05T14:48:00.000Z" | luxon({ input: { zone: "client" } }) }}

Or you can set the default input and output in the Vue.use function to use these templates by default:

Vue.use(VueLuxon, {
    input: "server",
    output: "client",
});

Or create custom templates to use everywhere:

Vue.use(VueLuxon, {
	templates: {
		serverAMS: {
			zone: "Europe/Amsterdam",
			format: "dd-MM-yyyy HH:mm:ss"
		},
        serverUTC: {
			zone: "UTC",
			format: "yyyy-MM-dd HH:mm:ss"
		},
        clientAMS: {
            zone: "Europe/Amsterdam",
			format: "med"
        }
	},
    input: "serverUTC",
    output: "clientAMS",
});

Tokens

Tokens are useful for formatting and parsing.

You can use the following tokens:

| Standalone token | Format token | Description | Example | | ---------------- | ------------ | ------------------------------------------------------------ | ----------------------------------------------------------- | | S | | millisecond, no padding | 54 | | SSS | | millisecond, padded to 3 | 054 | | u | | fractional seconds, functionally identical to SSS | 054 | | s | | second, no padding | 4 | | ss | | second, padded to 2 padding | 04 | | m | | minute, no padding | 7 | | mm | | minute, padded to 2 | 07 | | h | | hour in 12-hour time, no padding | 1 | | hh | | hour in 12-hour time, padded to 2 | 01 | | H | | hour in 24-hour time, no padding | 9 | | HH | | hour in 24-hour time, padded to 2 | 13 | | Z | | narrow offset | +5 | | ZZ | | short offset | +05:00 | | ZZZ | | techie offset | +0500 | | ZZZZ | | abbreviated named offset | EST | | ZZZZZ | | unabbreviated named offset | Eastern Standard Time | | z | | IANA zone | America/New_York | | a | | meridiem | AM | | d | | day of the month, no padding | 6 | | dd | | day of the month, padded to 2 | 06 | | c | E | day of the week, as number from 1-7 (Monday is 1, Sunday is 7) | 3 | | ccc | EEE | day of the week, as an abbreviate localized string | Wed | | cccc | EEEE | day of the week, as an unabbreviated localized string | Wednesday | | ccccc | EEEEE | day of the week, as a single localized letter | W | | L | M | month as an unpadded number | 8 | | LL | MM | month as an padded number | 08 | | LLL | MMM | month as an abbreviated localized string | Aug | | LLLL | MMMM | month as an unabbreviated localized string | August | | LLLLL | MMMMM | month as a single localized letter | A | | y | | year, unpadded | 2014 | | yy | | two-digit year | 14 | | yyyy | | four- to six- digit year, pads to 4 | 2014 | | G | | abbreviated localized era | AD | | GG | | unabbreviated localized era | Anno Domini | | GGGGG | | one-letter localized era | A | | kk | | ISO week year, unpadded | 17 | | kkkk | | ISO week year, padded to 4 | 2014 | | W | | ISO week number, unpadded | 32 | | WW | | ISO week number, padded to 2 | 32 | | o | | ordinal (day of year), unpadded | 218 | | ooo | | ordinal (day of year), padded to 3 | 218 | | D | | localized numeric date | 9/4/2017 | | DD | | localized date with abbreviated month | Aug 6, 2014 | | DDD | | localized date with full month | August 6, 2014 | | DDDD | | localized date with full month and weekday | Wednesday, August 6, 2014 | | t | | localized time | 9:07 AM | | tt | | localized time with seconds | 1:07:04 PM | | ttt | | localized time with seconds and abbreviated offset | 1:07:04 PM EDT | | tttt | | localized time with seconds and full offset | 1:07:04 PM Eastern Daylight Time | | T | | localized 24-hour time | 13:07 | | TT | | localized 24-hour time with seconds | 13:07:04 | | TTT | | localized 24-hour time with seconds and abbreviated offset | 13:07:04 EDT | | TTTT | | localized 24-hour time with seconds and full offset | 13:07:04 Eastern Daylight Time | | f | | short localized date and time | 8/6/2014, 1:07 PM | | ff | | less short localized date and time | Aug 6, 2014, 1:07 PM | | fff | | verbose localized date and time | August 6, 2014, 1:07 PM EDT | | ffff | | extra verbose localized date and time | Wednesday, August 6, 2014, 1:07 PM Eastern Daylight Time | | F | | short localized date and time with seconds | 8/6/2014, 1:07:04 PM | | FF | | less short localized date and time with seconds | Aug 6, 2014, 1:07:04 PM | | FFF | | verbose localized date and time with seconds | August 6, 2014, 1:07:04 PM EDT | | FFFF | | extra verbose localized date and time with seconds | Wednesday, August 6, 2014, 1:07:04 PM Eastern Daylight Time | | q | | quarter, no padding | 9 | | qq | | quarter, padded to 2 | 13 |

Change the $luxon method name

Provide a methodName in the settings object.

Tips

• Save and serve your datetimes from the server in the utc time zone and the iso or sql format. Then use the client's locale format.
