Date and Time#

Long Format Date#

/**
 * Display the date in long format
 */
function dateNumeric(): string {
  const today = new Date();
  return today.toLocaleDateString("fr-FR", {
    weekday: "long",
    day: "numeric",
    month: "long",
    year: "numeric",
  });
} // output: dimanche 8 janvier 2023typescript

Short Format Date#

/**
 * Display the date in short format
 */
function dateLong(): string {
  const today = new Date();
  return today.toLocaleDateString("fr-FR");
} // output: 08/01/2023typescript

Size Converter#

function convertSize(size: number, fixed: number): string {
  const units = ["Ko", "Mo", "Go", "To", "Po"];
  const unitIndex = Math.floor(Math.log(size) / Math.log(1024));
  return `${(size / Math.pow(1024, unitIndex)).toFixed(fixed)} ${
    units[unitIndex]
  }`;
}typescript

Bandwidth Converter#

Convert to Mbps#

function convertBandwidth(bandwidth: number, fixed: number): string {
  return `${parseFloat((bandwidth / 125000).toFixed(fixed))} Mbps`;
}typescript

Convert with Units#

function convertBandwidthWithUnits(bandwidth: number, fixed: number): string {
  const units = ["bps", "Kbps", "Mbps", "Gbps", "Tbps"];
  const unitIndex = Math.floor(Math.log(bandwidth) / Math.log(1000));
  return `${(bandwidth / Math.pow(1000, unitIndex)).toFixed(fixed)} ${
    units[unitIndex]
  }`;
}typescript

Capitalize the First Letter#

function capitalise(str: string): string {
  return str[0].toUpperCase() + str.slice(1);
}typescript

Generate UUID#

const uuid = (number: number = 32): string => {
  const gen = (x: string, number: number): string =>
    Array.from(
      { length: number ? number : 1 },
      () => x[Math.floor(Math.random() * x.length)]
    ).join("");
  return gen(
    "0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ",
    number
  );
};typescript

Generate a Random Number or String#

const randomGen = {
  NC: "0123456789",
  LC: "abcdefghijklmnopqrstuvwxyz",
  UC: "ABCDEFGHIJKLMNOPQRSTUVWXYZ",

  _generate(c: string, n: number): string {
    return Array.from(
      { length: n ? n : 1 },
      () => c[Math.floor(Math.random() * c.length)]
    ).join("");
  },

  number(n: number): string {
    return this._generate(this.NC, n);
  },
  lowercase(n: number): string {
    return this._generate(this.LC, n);
  },
  uppercase(n: number): string {
    return this._generate(this.UC, n);
  },
  all(n: number): string {
    return this._generate(this.NC + this.UC + this.LC, n);
  },
};

console.log(randomGen.number(10)); // 9836102222typescript
