A repository to save useful functions that I created or found on internet or for personal projects

Typescript

Encrypt strings

import bcrypt from "bcrypt";

export const encrypt = async (query: string, salt = 10): Promise<string> => {
	const hashedPassword = await bcrypt.hash(query, salt);

	return hashedPassword;
};

export const compareEncrypted = async (
	queryEncrypted: string,
	query: string
): Promise<boolean> => {
	const isEqual = await bcrypt.compare(query, queryEncrypted);

	return isEqual;
};
 

Format Date into simple date

function formatDate(inputDateString: string) {
	const date = new Date(inputDateString);
	const year = date.getFullYear();
	const month = String(date.getMonth() + 1).padStart(2, "0");
	const day = String(date.getDate()).padStart(2, "0");

	return `${year}-${month}-${day}`;
}

Convert file to base64

export const convertFileToBase64 = (file: File): Promise<string> => {
  return new Promise((resolve, reject) => {
    const reader = new FileReader();
    reader.onload = () => resolve(reader.result as string);
    reader.onerror = (error) => reject(error);
    reader.readAsDataURL(file);
  });
};
