    A JavaScript utility for handling person names. Try it live.


    Check out the official documentation at https://namefully.netlify.app.


    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.

    Key features

    1. Offer supports for Latin alphabet, including other European ones (e.g., German, Greek, Cyrillic, Icelandic characters)
    2. Accept different data shapes as input
    3. Use of optional parameters to access advanced features
    4. Format a name as desired
    5. Offer support for prefixes and suffixes
    6. Access to names' initials
    7. Allow hyphenated names, including with apostrophes

    Advanced features

    1. Alter the order of appearance of a name: by given name or surname
    2. Handle various subparts of a surname and given name
    3. Use tokens (separators) to reshape prefixes and suffixes
    4. Accept customized parsers (do it yourself)


    npm i namefully



    Related packages

    This package is also available in Angular and React:


    import { Namefully } from 'namefully'
    const name = new Namefully('John Joe Smith')
    console.log(name.format('L, f m')) // => SMITH, John Joe
    console.log(name.zip()) // => John J. Smith

    NOTE: This package comes with its own declaration file for TypeScript support.

    Options and default values

    Below are enlisted the options supported by namefully.


    string: 'firstname' | 'lastname', default: firstname

    Indicate in what order the names appear when set as a 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 name = new Namefully('Smith John Joe', { orderedBy: 'lastname' })
    console.log(name.ln()) // => Smith
    // 'Edison' is the surname in this string array case
    const name = new Namefully(['Edison', 'Thomas'], { orderedBy: 'lastname' })
    console.log(name.fn()) // => 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: 'lastname' })
    console.log(name.full()) // => Smith John Joe
    // Now alter the order by choosing the given name first
    console.log(name.full('firstname')) // => John Joe Smith


    enum: 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('Adam,Sandler', { separator: Separator.COMMA })
    console.log(name.full()) // => Adam Sandler


    string: 'uk' | 'us', default: uk

    Abide 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'
    }, { titling: 'us' })
    console.log(name.full()) // => Mr. John Smith
    console.log(name.px()) // => Mr.


    boolean, default: false

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

    const name = new Namefully({
        prefix: 'Mr',
        firstname: 'John',
        lastname: 'Smith',
        suffix: 'PhD'
    }, { ending: true })
    console.log(name.full()) // => Mr John Smith, PhD


    string: 'father' | 'mother' | 'hyphenated' | 'all', default: father

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

    import { Namefully, Firstname, Lastname } from 'namefully'
    const fn = new Firstname('Jaden')
    const ln = new Lastname('Smith', 'Pinkett')
    const name = new Namefully([fn, ln], { lastnameFormat: 'hyphenated' })
    console.log(name.full()) // => Jaden Smith-Pinkett


    boolean, default: false

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

    const name = new Namefully('2Pac Shakur', { bypass: true }) // normally would fail the regex
    console.log(name.fn()) // => 2Pac

    NOTE: This option can help to trick the utility and allow us to use it for unsupported languages or inner contents like prefixes or suffixes. For example, the Hindi characters will not pass the validation rules. Or, the Spanish equivalent for Mr => Sr will raise an exception as it is not part of the predefined prefixes.


    object, default: null

    Customize your own parser to indicate the full name yourself.

    import { Namefully, Firstname, Lastname, Parser } from 'namefully'
    // Suppose you want to cover this '#' separator
    class MyParser implements Parser<string> {
        constructor(public raw: string) {}
        parse() {
            const [fn, ln] = this.raw.split('#');
            return {
                firstname: new Firstname(fn),
                lastname: new Lastname(ln),
    const name = new Namefully(null, { parser: new MyParser('Juan#Garcia') })
    console.log(name.full()) // => Juan Garcia

    To sum up, the default values are:

        "orderedBy": "firstname",
        "separator": " ",
        "titling": "uk",
        "ending": false,
        "lastnameFormat": "father",
        "bypass": false,
        "parser": null

    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 here) 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.

    Basic cases

    Let us take a common example:

    Mr John Joe Smith PhD

    So, this utility understands the name parts as follows:

    • typical name: John Smith
    • first name: John
    • middle name: Joe
    • last name: Smith
    • prefix: Mr
    • suffix: PhD
    • full name: Mr John Joe Smith PhD
    • birth name: John Joe Smith
    • zipped: John J. Smith
    • initials: J J S
    • usernames: jsmith, johnsmith, etc.


    namefully does not have support for certain use cases:

    • mononame: Plato. It can be tricked though by setting the mononame as both first and last name;
    • multiple surnames: De La Cruz, Da Vinci. You can also trick it using your own parsing method or setting separately each name part via the Nama|Name type or the string array input;
    • multiple prefixes: Prof. Dr. Einstein. An alternative would be to use the bypass option.

    See the use cases for further details.

    getFullname orderedBy null string Gets the full name
    getBirthname orderedBy null string Gets the birth name, no prefix or suffix
    getInitials orderedBy, withMid null, false string Gets the initials of the first and last names
    describe nameType null Summary Gives some descriptive statistics of the characters' distribution.
    shorten orderedBy null string Returns a typical name (e.g. first and last name)
    compress limit, by 20, middlename string Compresses a name using different forms of variants
    username none none string[] Suggests possible (randomly) usernames closest to the name
    format how null string Formats the name as desired
    zip nameType null string Shortens a full name

    passwd nameType null string Returns a password-like representation of a name


    If you find the names of the methods somewhat too long, we provide aliases to make your life easier as a coder.
