  -h, --host             IP address/Hostname for database server
                                                          [default: "127.0.0.1" or "localhost"]
  -d, --database         Database name                             [required]
  -u, --user             Username for database server              [required]

Examples

• Creating seed from local Postgres database
  • Global module

    seederalize -h localhost -d postgres -u postgres -x !Passw0rd -e postgres -o .
    

  • Npx Way

    npx seederalize -h localhost -d postgres -u postgres -x !Passw0rd -e postgres -o .
    

Hashing passwords

• you can see how we hash passwords using md5 package like below:

  function hashPass(rawPassword, { salt = 15, rounds = 10 }) {
  
    let hashed = md5(rawPassword + salt);
    for (let i = 0; i <= rounds; i++) {
      hashed = md5(hashed);
    }
  
    return `${salt}$${rounds}$${hashed}`;
  }
  

• if you want to use it in your code to compare passwords, here you are:

  function compare(rawPassword, hashedPassword) {
    try {
      const [ salt, rounds ] = hashedPassword.split('$');
  
      const hashedRawPassword = hashPass(rawPassword, { salt, rounds });
      return hashedPassword === hashedRawPassword;
    } catch (error) {
      throw Error(error.message);
    }
  }
