Documentation

Motivation

Have you ever had to format a user's name in a particular order, way, or shape? Probably yes. If not, it will come at some point. Be patient.

You may want to use this library if:

you've been repeatedly dealing with users' given names and surnames;
you need to occasionally format a name in a particular order, way, or shape;
you keep copy-pasting your name-related business logic for every project;
you're curious about trying new, cool stuff.

Key features

Accept different data shapes as input
Use optional parameters to access advanced features
Format a name as desired
Offer support for prefixes and suffixes
Access to names' initials
Support hyphenated names (and other special characters)
Offer predefined validation rules for many writing systems, including the Latin and European ones (e.g., German, Greek, Cyrillic, Icelandic characters)

Advanced features

Alter the name order anytime
Handle various parts of a surname and a given name
Use tokens (separators) to reshape prefixes and suffixes
Accept customized parsers (do it yourself)
Parse non-standard name cases

Installation

npm i namefully

Dependencies

None

Usage

See example/example.ts.

import { Namefully } from 'namefully'

const name = new Namefully('Thomas Alva Edison');
console.log(name.short); // Thomas Edison
console.log(name.public); // Thomas E
console.log(name.initials()); // ['T', 'A', 'E']
console.log(name.format('L, f m')); // EDISON, Thomas Alva
console.log(name.zip()); // Thomas A. E.

NOTE: if you intend to use this utility for non-standard name cases such as many middle names or last names, some extra work is required. For example, using Namefully.parse() lets you parse names containing many middle names with the risk of throwing a NameError when the parsing is not possible.

`Config` and default values

Config is a single configuration to use across the other components.

The multiton pattern is used to keep one configuration across the Namefully setup. This is useful for avoiding confusion when building other components such as FirstName, LastName, or Name of distinct types (or Namon) that may be of particular shapes.

Below are enlisted the options supported by namefully.

orderedBy

NameOrder - default: NameOrder.FIRST_NAME

Indicates in what order the names appear when set as raw string values or string array values. That is, the first element/piece of the name is either the given name (e.g., Jon Snow) or the surname (e.g.,Snow Jon).

// 'Smith' is the surname in this raw string case
const name1 = new Namefully('Smith John Joe', { orderedBy: NameOrder.LAST_NAME });
console.log(name1.last); // Smith

// 'Edison' is the surname in this string array case
const name2 = new Namefully(['Edison', 'Thomas'], { orderedBy: NameOrder.LAST_NAME });
console.log(name2.first); // Thomas

NOTE: This option also affects all the other results of the API. In other words, the results will prioritize the order of appearance set in the first place for the other operations. Keep in mind that in some cases, it can be altered on the go. See the example below.

// 'Smith' is the surname in this raw string case
const name = new Namefully('Smith John Joe', { orderedBy: NameOrder.LAST_NAME });
console.log(name.fullName()); // Smith John Joe

// Now alter the order by choosing the given name first
console.log(name.fullName(NameOrder.FIRST_NAME)); // John Joe Smith

separator

Separator - default: Separator.SPACE

Only valid for raw string values, this option indicates how to split the parts of a raw string name under the hood.

const name = new Namefully('John,Smith', { separator: Separator.COMMA });
console.log(name.full); // John Smith

title

Title - default: Title.UK

Abides by the ways the international community defines an abbreviated title. American and Canadian English follow slightly different rules for abbreviated titles than British and Australian English. In North American English, titles before a name require a period: Mr., Mrs., Ms., Dr.. In British and Australian English, no periods are used in these abbreviations.

const name = new Namefully({
  prefix: 'Mr',
  firstName: 'John',
  lastName: 'Smith',
}, { title: Title.US });
console.log(name.full); // Mr. John Smith
console.log(name.prefix); // Mr.

ending

boolean - default: false

Sets an ending character after the full name (a comma before the suffix actually).

const name = new Namefully({
    firstName: 'John',
    lastName: 'Smith',
    suffix: 'Ph.D'
}, { ending: true })
console.log(name.full) // John Smith, Ph.D
console.log(name.suffix) // Ph.D

surname

Surname - default: Surname.FATHER

Defines the distinct formats to output a compound surname (e.g., Hispanic surnames).

const name = new Namefully(
    [FirstName('John'), LastName('Doe', 'Smith')],
    { surname: Surname.HYPHENATED },
);
console.log(name.full); // John Doe-Smith

bypass

boolean - default: true

Skips all the validators (i.e., validation rules, regular expressions).

const name = new Namefully(
  {
    firstName: 'John',
    lastName: 'Smith',
    suffix: 'M.Sc.', // will fail the validation rule and throw an exception.
  },
  { bypass: false, ending: true },
);

To sum it all up, the default values are:

{
    orderedBy: NameOrder.FIRST_NAME,
    separator: Separator.SPACE,
    title: Title.UK
    ending: false,
    bypass: true,
    surname: Surname.FATHER
}

Do It Yourself

Customize your own parser to indicate the full name yourself.

import { Config, FullName, Namefully, Parser } from 'namefully'

// Suppose you want to cover this '#' separator
class SimpleParser extends Parser<string> {
    parse(options: Partial<Config>): FullName {
        const [firstName, lastName] = this.raw.split('#')
        return FullName.parse({ firstName, lastName }, Config.merge(options))
    }
}

const name = new Namefully(SimpleParser('Juan#Garcia'));
console.log(name.full); // Juan Garcia

Concepts and examples

The name standards used for the current version of this library are as follows:

[prefix] firstName [middleName] lastName [suffix]

The opening [ and closing ] brackets mean that these parts are optional. In other words, the most basic/typical case is a name that looks like this: John Smith, where John is the firstName and Smith, the lastName.

NOTE: Do notice that the order of appearance matters and (as shown in orderedBy) can be altered through configured parameters. By default, the order of appearance is as shown above and will be used as a basis for future examples and use cases.

Once imported, all that is required to do is to create an instance of Namefully and the rest will follow.
