Welcome to the iso_8583 wiki!

Welcome to the hows of iso_8583

iso_8583 is available as an npm package here https://www.npmjs.com/package/iso_8583 The best use case is with a nodejs tcp client or server sending/receiving messsages to/from an ISO 8583 interface

How to install and use iso_8583

Usage: For Bitmap Messaging

Install from npm using

npm install --save iso_8583

Import the library using:

let iso_8583 = require('iso_8583')

To invoke the package initialize with the iso8583 json or object as argument. If the json contains any fields not defined in iso8583 or has no field 0, the error is returned in an object.

let testData = { "0": "0100", "2": "5413330", "3": "000000", "4": "000000002000", "7": "0210160607", "11": "148893", "12": "160607", "13": "0210", "14": "2512", "18": "4111", "22": "141", "23": "003", "25": "00", "26": "12", "35": "5413330089020011D2512601079360805F", "41": "31327676", "42": "4D4F424954494C4", "43": "My Termianl Business ", "49": "404", "45": "0303030204E4149524F4249204B452dataString04B45", "123": "09010001000105010103040C010001" };

let isopack = new iso_8583(isoJson)

The object initialized has the following methods:

To get the mti as a string:

isopack.getMti()

returns a 4 byte buffer containing the mti

To get the bitmaps in binary:

isopack.getBmpsBinary()

returns a string 111100100011110001000110110...

or an error object with error prop

To get the bitmaps in hex:

isopack.getBitMapHex()

returns a hexadecimal string f23c46c020e880000000000000000020

or an error object with error prop

To get the assembled data:

isopack.assembleDataElements()

returns an object with props data and length 07541333000000000000000200002101606.. 253

or an error object with error prop

To save the hustle, you can get all this information in one object

isopack.getBmpPack()

returns

{ mti: '0100', bitmapHex: 'f23c46c020e880000000000000000020', dataString: '07541333000000000000000200002101606071488931606070210251241111410030012345413330089020011D2512601079360805F313276764D4F424954494C44D6F6269746C6C204D65726368616E7420312030450303030204E4149524F4249204B452dataString04B4540403009010001000105010103040C010001', length: 273, lengthIndicator: [ '1', 17 ] }

To get a buffer tcp message to send to the ISO 8584 Interface:

let bufferMessage = isopack.getBufferMessage();

This returns a buffer containing the message or an object containing error message <Buffer 01 11 30 31 30 30 f2 3c 46 c0 20 e8 80 00 00 00 00 00 00 00 00 20 30 37 35 34 ...

To upuck a message from the interface, that always comes in a tcp stream/buffer

Just parse the incoming buffer or string to the method

let incoming = new isopack().getIsoJSON(incoming)

This returns a json object of the message let testData = { "0": "0100", "2": "5413330", "3": "000000", "4": "000000002000", "7": "0210160607", "11": "148893", "12": "160607", "13": "0210", "14": "2512", "18": "4111", "22": "141", "23": "003", "25": "00", "26": "12", "35": "5413330089020011D2512601079360805F", "41": "31327676", "42": "4D4F424954494C4", "43": "My Termianl Business ", "49": "404", "45": "0303030204E4149524F4249204B452dataString04B45", "123": "09010001000105010103040C010001" };

Usage: For XML Messaging: To get xml from a json:

Initialize the iso object with the json as argument

let isoPack = new isoPack(testData)

isoPack.getXMLString()

returns a string of iso 8583 xml string To get json form the xml string

Initialize with no argument

let isoPack = new isoPack()

parse the string to the method to get the iso json

let xmlTets = '\n' + '\n' + '0200\n' + '\n' + '<Field_002>4839123456709012</Field_002>\n' + '<Field_003>000000</Field_003>\n' + '<Field_004>000000001500</Field_004>\n' + '<Field_007>0604074705</Field_007>\n' + '<Field_011>804058</Field_011>\n' + '<Field_012>074808</Field_012>\n' + '<Field_013>0604</Field_013>\n' + '<Field_014>0812</Field_014>\n' + '<Field_015>0905</Field_015>\n' + '<Field_022>901</Field_022>\n' + '<Field_025>02</Field_025>\n' + '<Field_026>05</Field_026>\n' + '<Field_028>000000500</Field_028>\n' + '<Field_030>000000500</Field_030>\n' + '<Field_032>483912</Field_032>\n' + '<Field_035>4839123456709012=08125876305082011</Field_035>\n' + '<Field_037>D000A0030000</Field_037>\n' + '<Field_040>507</Field_040>\n' + '<Field_041>FOFUGUT1</Field_041>\n' + '<Field_042>191121119111112</Field_042>\n' + '<Field_043>Postilion Cafeteria Rondebosch ZA</Field_043>\n' + '<Field_049>710</Field_049> <Field_056>1510</Field_056>\n' + '<Field_059>0000000072</Field_059>\n' + '<Field_123>211401213041013</Field_123>\n' + '<Field_127_002>0007713856</Field_127_002>\n' + '<Field_127_009>013040604040604016501100330000</Field_127_009>\n' + '<Field_127_012>My Terminal Business</Field_127_012>\n' + '<Field_127_020>20100604</Field_127_020>\n' + '\n' + ''

isoPack.getJsonFromXml(xmlTets)

returns a json object or an error object Thanks, Have Fun
