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 7.6(x64)
SWIG: 4.0.0
GCC: 4.8.5
Node.js: v8/v10
GridDB Server and C Client: 4.1 CE
