Informix native node.js driver - node-informixdb:

Informix native node.js driver is a high performance driver with asynchronous/synchronous interface suitable for highly scalable enterprise applications and lightweight enough for Internet of things (IoT) solutions working with Informix database.

Supported Platforms - Windows64, Linuxx64, Linuxia32, AIX.

Supported Node.js Versions

Recommended version of node.js is >= V10.X

The latest node.js version using which informixdb is tested: 14.9.0

Prerequisite

  • Python 2.7 is required by node-gyp.

  • Informix ODBC (It will get download automatically while installation, if CSDK_HOME/INFORMIXDIR is not set.)

  • If Windows Platform: for compilation of informixdb Visual Studio is required, if not available then module will install with "pre-compiled" binary version.

  • If Linux Platform: for compilation of informixdb C++11 compiler is required, if not available then module will install with "pre-compiled" binary version. (Note the default compiler on RHEL 6 does not have the required support. Install a newer compiler or upgrade the older one.)

Important Environment Variables and Download Essentials

** To use exiting CSDK installation directory set below env variables, it will prevent automatic download of Informix ODBC driver **

CSDK_HOME:

  • USE:

    • On distributed platforms, set this environment variable if you want to compile/build the informixdb module.
  • HOW:

    • Set CSDK_HOME environment variable to a pre-installed Informix CSDK installation directory.

INFORMIXDIR:

  • USE:

    • On distributed platforms, set this environment variable if you want to compile/build the informixdb module.
  • HOW:

    • Set INFORMIXDIR environment variable to a pre-installed Informix CSDK installation directory.

CSDK_INSTALLER_URL :

  • USE:

    • Set this environment variable to by-pass the HCL Hosted URL for downloading odbc driver.
  • HOW:

    • Set CSDK_INSTALLER_URL environment variable with alternate odbc/driver downloading URL link or with locally downloaded "tar/zipped driver's parent directory path.
  • TIP:

    • If you don't have alternate hosting URL then, you can download the tar/zipped file of driver from the HCL Hosted URL and can set the CSDK_INSTALLER_URL environment variable to the downloaded "tar/zipped driver's" parent directory path. No need to untar/unzip the driver and do not change the name of downloaded file.

Download onedb-odbc-driver (based on your platform & architecture) from the below HCL Hosted URL:

Informix ODBC Drivers for Specific Platform and Architecture

Platform Architecture ODBC Driver Supported
Linux x64 OneDB-Linux64-ODBC-Driver.tar.gz Yes
Windows x64 OneDB-Win64-ODBC-Driver.zip Yes

Install

You may install the package using npm install command:

npm install informixdb

or, you can install the latest driver from Github (Not recommanded for production use):

npm install git+https://github.com/OpenInformix/node-informixdb.git

For more installation details please refer: INSTALLATION GUIDE

API Documentation

For complete list of informixdb APIs and example, please check API DOCUMENTATION

Quick Example

var informix = require('informixdb');
 
informix.open("SERVER=dbServerName;DATABASE=dbName;HOST=hostName;SERVICE=port;UID=userID;PWD=password;", function (err,conn) {
  if (err) return console.log(err);
  
  conn.query('select 1 from table(set{1})', function (err, data) {
    if (err) console.log(err);
    else console.log(data);
 
    conn.close(function () {
      console.log('done');
    });
  });
});

How to get an informixdb instance?

The simple api is based on the instances of Database class. You may get an instance by one of the following ways:

require("informixdb").open(connectionString, function (err, conn){
  //conn is already open now if err is falsy
});

or by using the helper function:

var informix = require("informixdb")();

or by creating an instance with the constructor function:

var Database = require("informixdb").Database
  , informix = new Database();

Debug

If you would like to enable debugging messages to be displayed you can add the flag DEBUG to the defines section of the binding.gyp file and then execute node-gyp rebuild.

<snip>
'defines' : [
  "DEBUG"
],
<snip>

Un-Install

To uninstall informixdb from your system, just delete the node-informixdb or informixdb directory.

For AIX install issue

If npm install informixdb aborts with "Out Of Memory" error on AIX, first run ulimit -d unlimited and then npm install informixdb.
