paper-profiler v1.0.2

paper profiler

Really dumb profiling for NodeJS

Example

var express = require( 'express' );
var profile = require( 'paper-profile' ).create();
var fs = require( 'fs' );
var path = require( 'path' );
var service = require( './service' );

var app = express();

app.get( '/', function( req, res, next ) {
    var reqId = req.get( 'X-request-id' );
    profile( reqId, 'getInfo' );

    server.getInfo( function( err, data ) {
        if ( err ) {
            res.send( 500 );
            return;
        }
        profile( reqId, 'getInfo' );

        profile( reqId, 'writeToFile' );
        fs.writeFileSync( path.join( __dirname, 'path', 'to', 'file' ), JSON.stringify( data ), 'utf8' );
        profile( reqId, 'writeToFile' );

        console.log( 'Times', profile.getTimes( reqId ) );
        profile.done( reqId );
        res.send( data );
    });

});

app.listen( 8080, function() {
    console.log( 'Server started up' );
});

Standard out might look like:

Server started up
Times [{"name":"getInfo","elapsedTime":"0.51s"},{"name":"writeToFile","elapsedTime":"1.32s"}]
