Node-ADT

New in v1.1.4: Support for Date, DateTime and NChar field types

Node ADT is a small fast library for reading Advantage Database Server database files (.ADT). It is a quick node port from the awesome rubygem by Chase Gray.

• Original Project page: http://github.com/chasemgray/Ruby-ADT

Installation

npm install node_adt

Basic Usage

    var Adt = require('node_adt');
    var adt = new Adt();

    adt.open('table.adt', 'ISO-8859-1', function(err, table) {

      console.log(table.header.recordCount);
      console.log(table.columns);

      table.eachRecord(function(err, record) {
        console.log(record.Name);
        console.log(record.Email);
      });

      table.findRecord(0, function(err, record) {
        console.log(record.Name);
      });

      table.close(); // Optional
    });

Changes in v1.0: Please note: forEach has been renamed to eachRecord

Supported ADT field types

ADT Field | JavaScript ------------- | ----------- Character | String CiCharater | String NChar | String Logical | Boolean Double | Number Integer | Number ShortInteger| Number Date | Date Timestamp | Date

Limitations and known bugs

• The rubygem has many more features than this node package, such as CSV export and an ActiveRecord-like find method.
• ADT is read-only
• External index files are not used

Acknowledgements

Thank you, Chase Gray, for all the hard work of figuring out how the ADT format works.

Thank you, @yortus for contributing bug fixes and support for Date, Timestamp and NChar fields types. 🎉
