node-triod-pq

Async non blocking connector from Node.js to PostgreSQL via libpq. N-API AsyncWorker class used.

It is my own implementation, based on my own requirements.

1. Fast.
2. Simple.
3. Minimal code size. Aprox 100 lines of c++ code.

Implemented 2 basic calls. PQexec() & PQexecParams() from libpq. This calls cover over 99% cases and requirements(my own). A tutorial, describing this project, can be found at the N-API Resource.

Requirements:

1. Installed Nodejs. May be with dev headers.
2. Working node-gyp and npm tools.
3. Working libpq library from PostgreSQL.
4. libpq use login/password/database name environment variables.
5. PostgreSQL's connection string NOT used. No plain text login/pass stored.
6. You should customize ./test/Test.js for meet yours environment.
7. Connector accept ONLY strings. Returns strings. Remember, always pass strings. For example not 5, but '5'

export PGUSER=username
export PGHOST=x.x.x.x
export PGPASSWORD=password
export PGDATABASE=dbname
export PGPORT=xxxx

To build and run this program on your system, clone it to your computer and run these two commands inside your clone:

npm install
npm test

Usage:
How to use, see ./test/Test.js. Connector returns 3 things. ntuples (row count), nfields (fields count). Returned data implemented as key-value Object properties, key is int. For example, sql_result[0] = '123456'; sql_result[1] = 'test data'; This is loop-optimized. If blob data returned (picture or other binary data), it encoded/escaped via PostgreSQL server, not connector. Connector simple pass As-Is.
