Edipsy

Decent EDI file parsing in Node.js.

Defining file schema

File schemas are defined by each type of register existing in the file to be parsed.

In this example, there are three type of registers: 0, 1 and 2.

You should also set a type for the field data. The available types are string, number and date. If you use the date field type, please note you can define the date format using the dateFormat option.

var EdiFile = require('../index').EdiFile;
 
var ediFile = new EdiFile({
    "0": [{
        name: 'user_name',
        start: 2,
        end: 17,
        type: 'string',
    }, {
        name: 'user_gender',
        start: 18,
        end: 18,
        type: 'string',
    }, {
        name: 'user_ssn',
        start: 19,
        end: 29,
        type: 'number',
    }, {
        name: 'user_born_at',
        start: 30,
        end: 38,
        type: 'date'
    }],
    "1": [{
        name: 'product_amount',
        start: 2,
        end: 7,
        type: 'number',
    }, {
        name: 'product_name',
        start: 8,
        end: 19,
        type: 'string',
    }, {
        name: 'product_bought_at',
        start: 20,
        end: 27,
        type: 'date'
    }],
    "2": [{
        name: 'products_amount',
        start: 2,
        end: 7,
        type: 'number',
    }, {
        name: 'products_count',
        start: 8,
        end: 10,
        type: 'number',
    }]
}, {
    dateFormat: "DDMMYYYY",
});

Parsing a file

var fileContent = '\
0JOHN APPLESEED  M1192171329619071996\n\
1300000MACBOOK AIR 11062015\n\
1150000IPHONE 6S   01082014\n\
2450000002';
 
var parsedFile = ediFile.parse(fileContent);

parsedFile will contain the parsed file separated by each type of register:

{ '0': 
   [ { user_name: 'JOHN APPLESEED',
       user_gender: 'M',
       user_ssn: 11921713296,
       user_born_at: Fri Jul 19 1996 00:00:00 GMT-0700 (PDT) } ],
  '1': 
   [ { product_amount: 300000,
       product_name: 'MACBOOK AIR',
       product_bought_at: Thu Jun 11 2015 00:00:00 GMT-0700 (PDT) },
     { product_amount: 150000,
       product_name: 'IPHONE 6S',
       product_bought_at: Fri Aug 01 2014 00:00:00 GMT-0700 (PDT) } ],
  '2': [ { products_amount: 450000, products_count: 2 } ] }
