JSDT require’s JSDoc - Node.js with MongoDB native example

by Paul Verest

Eclipse JSDT does not yet support CommonJS.

But when playing with latest mongodb module (check https://github.com/mongodb/node-mongodb-native),

I was astonished by popup window with Docs

and underline when holding Ctrl

and click through

That was not some new feature in JSDT from Kepler 4.3.1, but relatively old JSDoc support. So JSDT looks for all files in project ands processes sources, functions names & JSDoc annotations. Then I think, it matches by name.

In this line `var MongoClient = require(‘mongodb’).MongoClient, format = require(‘util’).format;’

‘MongoClient’ works, not because sources have JSDoc with annotation. It worked without it.

	/**
	 * @class Represents a MongoClient
	 * @param {Object} serverConfig server config object.
	 * @param {Object} [options] additional options for the collection.
	 */

UPDATE 2013-11-14:

This only works with <nature>org.eclipse.wst.jsdt.core.jsNature</nature> inside .project

otherwise there is error dialog when trying to click-though.
