Edits by Erez Bracha, original library here

This is a simple library to generate random teams of Pokémon.

Table of Contents:

• Options
• Returned Fields
• Non-Default Exports
• Examples

Options

Option	Type	Description	Default	Notes
number	number	Number of random Pokémon to generate	6	integer > 0
baby	boolean	Choose only baby Pokémon (species released in a later generation than their evolutions)	false
basic	boolean	Choose only basic Pokémon (lowest evolution stage excluding babies)	false
evolved	boolean	Choose only fully evolved Pokémon	false
type	string	Choose only Pokémon of this type	-	enter a single type's name in lowercase
randomType	boolean	Choose only Pokémon of a random type	false
superEffective	string	Choose only Pokémon super effective against this type	-	enter a single type's name in lowercase
unique	boolean	Choose no duplicate Pokémon	false
starter	boolean	Choose only Pokémon from the starter lines	false
legendary	boolean	Choose only Legendary and Mythical Pokémon (Legendary can be a controversial term)	false
mythical	boolean	Choose only Mythical Pokémon	false
forms	boolean	Include alternate forms of Pokémon in the results	false
generations	string[]	Choose Pokémon only from the specified generations	-	Example: ['1', '2', '4', '6']
customList	string[]	Specify names of Pokémon to choose from	-	Pokémon names must match internal names in all but case. Internal list can be obtained using the exported getPokemon function for increased ease.

Please note that some options are supposed to be mutually exclusive:

• Setting baby to true together with either basic and/or evolved would return no results
• Setting starter to true together with either legendary and/or mythical would return no results
• Setting both legendary and mythical to true is the same as just setting mythical to true
• randomType option will be ignored if you've set the type option
• Setting the customList option will cause all options except number, unique and forms to be ignored

Examples

import RandomPokemon from '@erezushi/pokemon-randomizer';

// No options - Chooses 6 random Pokémon
const result = RandomPokemon();
// result = [
//     { name: 'Pikachu', ... },
//     { name: 'Mewtwo', ... },
//     ...
// ]

// Chooses 3 random, unique, final stage Pokémon, that are super effective against fire
const fullyEvolved = RandomPokemon({
    number: 3,
    unique: true,
    evolved: true,
    superEffective: 'fire'
});
// fullyEvolved = [
//     { name: 'Blastoise', ... },
//     { name: 'Golem', ... },
//     { name: 'Omastar', ...},
// ]

// Using the customList option
const customList = [
    "charmander",
    "vulpix",
    "eevee",
    "latias",
    "zorua",
    "fennekin",
    "litten",
    "sprigatito",
];

const customFilter = RandomPokemon({
    number: 3,
    unique: true,
    customList,
});
// CustomFilter = [
//     { name: 'Fennekin' ... },
//     { name: 'Vulpix' ... },
//     { name: 'Latias' ... },
// ]
