The first section describes plv8x, and the later sections has some real-world examples such as:

http://www.audreyt.org/newdict/jekyller/_public/?full#pgrest-mongolab-api-server

PgREST is...

• a JSON document store
• running inside PostgreSQL
• working with existing relational data
• capable of loading Node.js modules
• compatible with MongoLab's REST API

Install plv8js extension for postgresql

Note: Requires postgresql 9.1 or later. 9.0 will be supported soon.

# for older distros: sudo add-apt-repository ppa:martinkl/ppa
sudo apt-get install libv8-dev

sudo easy_install pgxnclient
sudo pgxn install plv8

Try pgrest:

npm i
npm run prepublish

./node_modules/.bin/plv8x --db tcp://localhost/MYDB --import pgrest:./package.json
./node_modules/.bin/plv8x --db tcp://localhost/MYDB --inject 'plv8x_json pgrest_select(plv8x_json)=pgrest:pgrest_select'

# then this will give you json representation of "sometable":
MYDB=$ select pgrest_select('{"collection": "sometable", "l": 10}');

The parameter is similar to MongoLab's REST API for listing documents: https://support.mongolab.com/entries/20433053-rest-api-for-mongodb

Run test:

createdb test
export TESTDBUSERNAME=postgres # optional
export TESTDBNAME=test
npm i
npm run test
