TOPKAT-UTILS

Here are my utils for nodeJs / ReactJs.

It's strength is that it has a straight functional naming and is fast and lightweight. It includes a logger with color handling, data validation utils, date utils, mongoDb utils. Check the list above for the function list:

const topkatUtils = {
    isset, // check undefined or null values but not falsey
    random, // random number between two values
    cln, // clean string for print. Eg: undefined, null, NaN => '-'
    pad, // simple padStart for numbers
    isObject, // check is value is a "straight" object (not null, not date, not an array, not undefined...)
    /** return the number or the closest number of the range
     * * nb min max  => returns
     * * 7  5   10   => 7 // in the range
     * * 2  5   10   => 5 // below the min value
     * * 99 5   10   => 10// above the max value
     */
    minMax, // 
    generateToken(length, isUnique, mode: 'alphanumeric' | 'hexadecimal' = 'alphanumeric'): string,
    // average between array of values. Eg: [5, 15] => 10 
    average,
    // sum values in an array
    sumArray,
    // sort an array of urls (useful for expressJs or react router. It avoid generic route home/ to take precedence over a more specific route like home/dshboard1)
    sortUrlsByDeepnessInArrayOrObject,
    // like nodeJs path.join() but for urls
    urlPathJoin,
    // miniTemplater(`Hello {{name}}`, { name: 'John' }) => `Hello John`
    miniTemplater,

    // is number between
    isBetween,
