A simple nodejs reporting server that leverages NReports.

Prerequisites

• PhantomJS

Features

• Server
  • Report Runner

Installation and Startup

• Manually create Amazon SQS queue for the tasks.

Start Server

var NRunner = require('nrunner');

NRunner.Server.start();

Start Worker Service

var NRunner = require('nrunner');

NRunner.WorkerService.start();

Web Server API

Running reports - simple (GET)

• Use this method when you don't need to pass the data source data inline with the request.

  http://server/runner/report_id&param1=value1&param2=value2&expires=days&runmode=(inline|background)

  The report runner will load the report engine and pass in the parameters defined.

  • Query String Parameters
    • report - the unique id/name of the report to execute
    • output - the desired report output mode (html|pdf), defaults to html
    • expires - the amount of time the report should be available in the viewer and stored in reporting cache, defaults to 1 day
    • runmode - the behavior of the report runner, defaults to inline

      • inline mode - the report will be executed and pushed into reporting cache, the user will be immediatly redirected to the report viewier will the generated report instance token.

      • background mode - the report will be executed as a background task, the user will immedatly receive a JSON response containing the original request details, a report instance token, the url to view the report and a url to the cached report directly.

        • ####[Sample Response] javascript { report: sampleReport123, output: html, expires: 1, id: jlahdsdkas78a7dsdhajshd2 url: http://localhost/viewier/jlahdsdkas78a7dsdhajshd2 cached: https://nrunner.s3.amazonaws.com/reports/cache/2014-03/jlahdsdkas78a7dsdhajshd2.html parameters: [ { name : "param1", value: "value1"}, { name : "param2", value: "value2"} ] }

Running reports - advanced (POST)

  Report runner advanced works the same as the standard runner only you pass the parameters in the body of a post and can supply your datasource data inline.

Viewing reports

+ Call the viewer url with the token received from the reporting request. This behavior happens automatically via a server side redirect when you call the runner with a runmode = "inline".
