Examples
First of all, import the generate method using the following syntax:
import { generate } from "generate-unique-string";If you want a string with a word that is 5 letters long followed by 3 numbers, you can do the following:
generate({
minLength: 5,
maxLength: 5,
minNumberLength: 3,
maxNumberLength: 3,
});
// example result: 'ocean799'If you want 3 strings and want each of them to be longer than 7 letters, you can do the following:
generate({ minLength: 7, exactly: 3 });
// example result: ['customer', 'licence', 'solution']If you want 2 to 5 strings and want each of them to be composed of 3 words, you can do the following:
generate({ min: 2, max: 5, wordsPerString: 3 });
// example result: ['cleaners combining wheat', 'hispanic ruled for', 'illinois adam legislative']The seed will help yield exactly the same results multiple times when the same seed was used and the other inputs are identical
console.log(generate({ min: 2, max: 3, seed: "my-seed" }));
//output: ['plenty', 'pure']
console.log(generate({ min: 2, max: 3, seed: "my-seed" }));
//output: ['plenty', 'pure']Other examples are as follows:
console.log(generate());
//output: 'army'
console.log(generate(5));
//output: ['army', 'beautiful', 'became', 'if', 'actually']
console.log(generate({ min: 3, max: 10 }));
//output: ['became', 'arrow', 'article', 'therefore']
console.log(generate({ exactly: 2 }));
//output: ['beside', 'between']
console.log(generate({ exactly: 5, join: " " }));
//output: 'army beautiful became if exactly'
console.log(generate({ exactly: 5, join: "" }));
//output: 'armybeautifulbecameifexactly'
console.log(generate({ exactly: 2, minLength: 4 }));
//output: ['atom', 'window']
console.log(generate({ exactly: 5, maxLength: 4 }));
//output: ['army', 'come', 'eye', 'five', 'fur']
console.log(generate({ exactly: 3, minLength: 5, maxLength: 100000 }));
//output: ['understanding', 'should', 'yourself']
console.log(generate({ exactly: 5, wordsPerString: 2 }));
//output: [ 'salt practical', 'also brief', 'country muscle', 'neighborhood beyond', 'grew pig' ]
console.log(generate({ exactly: 5, wordsPerString: 2, separator: "-" }));
//output: [ 'equator-variety', 'salt-usually', 'importance-becoming', 'stream-several', 'goes-fight' ]
console.log(
generate({
exactly: 5,
wordsPerString: 2,
formatter: (word) => word.toUpperCase(),
})
);
//output: [ 'HAVING LOAD', 'LOST PINE', 'GAME SLOPE', 'SECRET GIANT', 'INDEED LOCATION' ]
