An universal & customable cemtext generator for batch transactions

Cemtext file format is a format used by banks to allow for batch transactions. Some bank have adopted this format by default, but each others can have a different format style. This module allows you to create a cemtext format by your own style—that means you can use it to meet your bank cemtext requirements. This module is fast, easy to understand, and more humanable.

Initialization

NPM

const vcmcemtex = require('vcmcemtex');

Browser

// Bower
<script src="bower_components/vcmcemtex/dist/vcmcemtex.min.js"></script>

Quickstart

vcmcemtex(params, options[optional]).then(cemtex => {
  console.log(cemtex);
});
  • Arguments

    • object params
      • object header [optional]
      • object detail [optional]
        • object keys
        • array data
      • object footer [optional]
    • object options [optional]
      • string charlen [optional]
        • default 160
      • boolean enter [optional]
        • default false
        • If true will add \n (enter) at every end of string.
  • Attributes

    • string type
      • lps | lpz | rps | rpz
      • default rps
      • LPS (Left Padding Space)
      • LPZ (Left Padding Zero)
      • RPS (Right Padding Space)
      • RPZ (Right Padding Zero)
    • number length
    • string|integer value
      • default ''
    • string|integer default
      • default ''
      • The default value to be used if there is no given value.
    • string countFromDetail
      • Use this if you want to count a number value from a key in params detail. You can see the usage on examples bellow.
      • Only works on header and footer.
    • boolean countAllData
      • default false
      • This will count all data in params detail and made it as a value.
      • Only works on header and footer.
    • boolean removeDot
      • default false
      • This will remove all dots.
    • boolean removeSpace
      • default false
      • This will remove all spaces.
    • boolean decimal
      • default true
      • This will convert float or decimal format to number.

Each successful generated row in a cemtext has length that equal to charlen—default is 160 characters. So it is 160 header length, 160 detail length (per 1 row), and 160 footer length. Example:

// string | length 4
'char'
// string | length 8
'username'
 
// and the cemtext output will be like this (in single string/one row):
 
'charusername                                                                                                                                                    '

You can change default charlen value by passing an options in second argument.

A simple cemtext format can be done like this:

vcmcemtex({
  header: {
    header1: { type: 'lps', length: 10, value: 'header' }
  },
  detail: {
    keys: {
      detail1: { type: 'lps', length: 10 }
    },
    data: [
      {
        detail1: 'detail'
      }
    ]
  },
  footer: {
    footer1: { type: 'lps', length: 10, value: 'footer' }
  }
}).then(cemtex => {
  console.log(cemtex);
});
 
// output
// '    header                                                                                                                                                          detail                                                                                                                                                          footer                                                                                                                                                      '

params object has 3 main keys; header, detail, and footer. You don't have to use them (optional), but it's always good to use them for best practice style.

If you prefer to use key detail, the key must have key keys and data. keys is an object, and the data must be an array object. The object keys between keys and data should be same, for example if keys has a key called detail1, then key data should contains a key called detail1—similliar to attribute value in header and footer.

You can see other examples bellow:

var data = [
  {
    name: 'John Doe',
    username: 'johndoe',
    email: 'johndoe@email.com',
    accountNumber: '123456789',
    testAmount: '12500'
  },
  {
    name: 'John Smith',
    username: 'johnsmith',
    email: 'johnsmith@email.com',
    accountNumber: '123456789',
    testAmount: '12500'
  },
  {
    name: 'John Adam',
  }
];
 
vcmcemtex({
  header: {
    record: { type: 'lps', length: 1, value: '1' },
    branch: { type: 'lpz', value: '1234' },

    test1: { type: 'rps', value: 'test1' },
    test2: { type: 'rps', value: 'test2' }
  },
  detail: {
    keys: {
      name: { type: 'rps', length: 10, default: '' },
      username: { type: 'rps', length: 10, default: '' },
      email: { type: 'rps', length: 20, default: '' },
      accountNumber: { type: 'lpz', length: 10, default: '' },
      testAmount: { type: 'lpz', length: 10, default: '' }
    },
    data: data
  },
  footer: {
    record: { type: 'lpz', length: 1, value: '3' },
    totalData: { type: 'lpz', length: 11, countAllData: true },
    totalAmount: { type: 'lpz', length: 11, countFromDetail: 'testAmount' }
  }
}, {
  charlen: 200
}).then(cemtex => {
  console.log(cemtex);
});
 
// output
