Node.js instances

Nodeclipse lets you define exact location of Node.js installations, or with checkbox "just node" let OS to find node on current PATH.

Hint: if you have 2 or more Node.js instances, let the newest be on PATH and select older in "Node path:". Then by checking/unchecking "just node" you can switch to and from the newest Node.js.

Node.js sources

If you got Node.js via pre-built installer, visit http://www.nodejs.org/download/ again to get Node.js sources and extract archive to a folder. Now you also have local copy of API documentations.

Node.js sources have "Node.js Core Modules" in lib folder, that may be useful.

Add following snippet to project .project file to reference Node.js sources.

    <linkedResources>
        <link>
            <name>nodejs-sources-lib</name>
            <type>2</type>
            <location>E:/Enide/node-sources/node-v0.10.19/lib/</location>
        </link>
    </linkedResources>

(This is done automatically if Node.js sources are selected since Nodeclipse 0.9)

Node.js modules

Node.js modules (in node_modules) usually have README.md file. To see README.md as it looks like on GitHub, right-click it and select Show in GFM view. Check also "Markdown" and "Github Flavored Markdown (GFM)" help pages.

Example

    var http = require('http');
    var server = http.createServer();
    var handleReq = function(req,res){
      res.writeHead(200, {});
      res.end('hello world');
    };
    server.on('request', handleReq);
    server.listen(8080);
    var fs = require('fs');
    fs.writeFile("/tmp/test", "Hey there!", function(err) {
        if(err) {
            console.log(err);
        } else {
            console.log("The file was saved!");
        }
    });
