pwix:date

What is it ?

A Meteor package to manage dates formats and conversions.

Should probably rather a NPMJS package. To be done someday.

Installation

This Meteor package is installable with the usual command:

    meteor add pwix:date

Usage

1    import { DateJs } from 'meteor/pwix:date';

Provides

DateJs

The exported DateJs global object provides following items:

Functions

DateJs.compare( a<Date|String|unset>, b<Date|String|unset>, opts<Object> )

Compare two dates, returning:

• -1 if a lesser (is before) b
• 0 if a equal b
• +1 if a greater (is after) b.

opts is an optional options object with following keys:

• start: whether an undefined, or null, or invalid date is considered to be the infinite start, defaulting to true. Set to false to consider an infinite end.

DateJs.compute( date<Date|String|unset>, days<Integer> )

Compute the resulting date+days.

Returns its result as a Date object.

Note that an undefined, or null, or invalid date is considered to be an infinite one, and cannot be computed here. We return null in this case.

DateJs.configure( o<Object> )

See below

Acts both as a getter and a setter.

A reactive data source.

DateJs.i18n.namespace()

Returns the i18n namespace used by the package. Used to add translations at runtime.

Available both on the client and the server.

DateJs.isInfinite( date<Date|String|unset> )

Returns true if the provided date is infinite whether it is infinite start or infinite end, false else.

Any null, or invalid or unset date is considered infinite.

DateJs.isValid( date<Date|String|unset> )

Returns true if the provided date is valid.

Any null, or invalid or unset date is considered invalid.

DateJs.sanitize( date<Date|String|unset> )

Sanitize the provided date, returning:

• either a valid Date object if the date is valid,

• or null if the date is invalid.

DateJs.strftime2jquery( format<String> )

Tries to convert a strftime date-time format to its jQuery equivalent.

Returns a jQuery-compatible format string.

DateJs.toMs( date<Date|String|unset>, defaultValue<Date|String|Integer|unset> )

Returns the milliseconds since Epoch of the provided date, defaulting to the provided default value, defaulting to the current local date.

DateJs.toString( date<Date|String|unset>, opts<Object> )

Returns the date as a string.

opts is an optional options object with following keys:

• format: the strftime desired format, defaulting to '%Y-%m-%d'

• default: the string to return if date is not set or empty, defaulting to ''.

Configuration

The package's behavior can be configured through a call to the DateJs.configure() method, with just a single javascript object argument, which itself should only contains the options you want override.

Known configuration options are:

• verbosity

  Define the expected verbosity level.

  The accepted value can be any or-ed combination of following:

  • DateJs.C.Verbose.NONE

    Do not display any trace log to the console

  • DateJs.C.Verbose.CONFIGURE

    Trace DateJs.configure() calls and their result

Please note that DateJs.configure() method should be called in the same terms both in client and server sides.

Remind too that Meteor packages are instanciated at application level. They are so only configurable once, or, in other words, only one instance has to be or can be configured. Addtionnal calls to DateJs.configure() will just override the previous one. You have been warned: only the application should configure a package.

DateJs.configure() is a reactive data source.

NPM peer dependencies

Starting with v 1.0.0, and in accordance with advices from the Meteor Guide, we no more hardcode NPM dependencies in the Npm.depends clause of the package.js.

Instead we check npm versions of installed packages at runtime, on server startup, in development environment.

Dependencies as of v 1.0.0:

1    'lodash': '^4.17.0',
2    'strftime': '^0.10.2'

Each of these dependencies should be installed at application level:

    meteor npm install <package> --save

Translations

New and updated translations are willingly accepted, and more than welcome. Just be kind enough to submit a PR on the Github repository.

Cookies and comparable technologies

None at the moment.
