GridDB Node.JS Client

GridDB Node.JS Client is developed using GridDB C Client and SWIG (Simplified Wrapper and Interface Generator).

Building of the library and execution of the sample programs have been checked in the following environment.

OS:              CentOS 6.9(x64)
SWIG:            3.0.12
GCC:             4.8.2
Node.js:         6
GridDB Server and C Client:   4.0 CE / 3.0 CE

Install SWIG as below.

$ wget https://sourceforge.net/projects/pcre/files/pcre/8.39/pcre-8.39.tar.gz
$ tar xvfz pcre-8.39.tar.gz
$ cd pcre-8.39
$ ./configure
$ make
$ make install

$ wget https://prdownloads.sourceforge.net/swig/swig-3.0.12.tar.gz
$ tar xvfz swig-3.0.12.tar.gz
$ cd swig-3.0.12
$ ./configure
$ make
$ make install

Install Node.js v6.

If required, change INCLUDES_JS path in Makefile.

Install gcc 4.8 as below.

1. Use python version 2:
    $ pyenv global 2.7.8
    $ pyenv rehash
2. Install devtoolset-2:
    $ wget http://people.centos.org/tru/devtools-2/devtools-2.repo -O /etc/yum.repos.d/devtools-2.repo
    $ yum install devtoolset-2-gcc devtoolset-2-binutils
    $ yum install devtoolset-2-gcc-c++ devtoolset-2-gcc-gfortran
3. Enable devtoolset-2:
    scl enable devtoolset-2 bash
    source /opt/rh/devtoolset-2/enable

Set LIBRARY_PATH.

export LIBRARY_PATH=$LIBRARY_PATH:<C client library file directory path>

1. Execute the command on project directory.

$ npm install nan
$ make

2. Set the NODE_PATH variable for griddb Node.js module files.

$ export NODE_PATH=<installed directory path>

3. Write require("griddb_node") in Node.js.

GridDB Server need to be started in advance.

1. Set LD_LIBRARY_PATH

    export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:<C client library file directory path>

2. The command to run sample

    $ node sample/sample.js <GridDB notification address> <GridDB notification port>
        <GridDB cluster name> <GridDB user> <GridDB password>
      -->['name01', false, 1, 'ABCDEFGHIJ' ]
