A Node.js module providing Express middleware to create an OSLC 3.0 server. The service uses the ldp-service Express middleware module which provides MongoDB for persistence, jsonld.js for JSON-LD support, and a few other JavaScript libraries. A sample app using the OSLC middleware service is running at http://oslc-browser.mybluemix.net.
oslc-service supports any OSLC Domain by including the domain vocabulary URIs at open-services.net/ns in the config.json file.
Many thanks to Steve Speicher and Sam Padgett for their valuable contribution to LDP and the LDP middleware upon which this service is built.
Module planning, maintenance and issues can be see at at the oslc-service IBM Bluemix DevOps Services project.
- Install the required modules
Install Node.js.
Install and start MongoDB.
Install express.js and create a sample express app
$ npm install express -g
$ express --git -e <appDir>
-
Edit the package.json file to add a dependency on ldp-service
"dependencies": {"oslc-service": "~0.0.1"},
-
Edit app.js and add whatever Express middleware you need including oslc-service. oslc-service also utilizes ldp-service which provides access to a MongoDB database in case additional middleware needs direct access to the database.
var ldpService = require('ldp-service'); app.use(ldpService()); var db = ldpService.db; // incase further middleware needs access to the database
-
Configuration defaults can be found in config.json. These may be overridden by variables in the environment, including Bluemix variables if deployed in a Bluemix app.
-
To start the app, run these commands
$ npm install $ node app.js
