# Instructions for maintainers of the nodereport project

## Publishing to the npm registry

The nodereport project is published as an npm native module

For each publish to npm:

- update the version property in the package.json file, incrementing the major, minor and patch level as appropriate
- update the CHANGES.md file with a list of commits since last release
- commit CHANGES.md and package.json to nodereport master branch
- tag commit with an annotated tag
- git checkout and npm publish the nodereport package

Suggested tooling is the slt-release script documented here: https://github.com/strongloop/strong-tools

nodereport is an add-on for Node.js, delivered as an npm native module,
which provides a human-readable diagnostic summary report, written
to file. The report is intended for development, test and production
use, to capture and preserve information for problem determination.
It includes Javascript and native stack traces, heap statistics,
It includes JavaScript and native stack traces, heap statistics,
platform information and resource usage etc. With the report enabled,
reports can be triggered on unhandled exceptions, fatal errors, signals
and calls to a Javascript API.
and calls to a JavaScript API. The module supports Node.js v4, v6 and v7
on Linux, MacOS and Windows.

Usage:

npm install nodejs/nodereport

var nodereport = require('nodereport');
npm install nodereport

By default, this will allow a NodeReport to be triggered via an API
call from a JavaScript application. The filename of the NodeReport is
returned. The default filename includes the date, time, PID and a
sequence number. Alternatively a filename can be specified on the API call.
call from a JavaScript application.

var nodereport = require('nodereport');
nodereport.triggerReport();

var filename = nodereport.triggerReport();
Content of the NodeReport consists of a header section containing the event
type, date, time, PID and Node version, sections containing JavaScript and
native stack traces, a section containing V8 heap information, a section
containing libuv handle information and an OS platform information section
showing CPU and memory usage and system limits. An example NodeReport can be
triggered using the Node.js REPL:

C:\test>node
> nodereport = require('nodereport')
> nodereport.triggerReport()
Writing Node.js report to file: NodeReport.20161020.091102.8480.001.txt
Node.js report completed
>

When a NodeReport is triggered, start and end messages are issued to stderr
and the filename of the report is returned to the caller. The default filename
includes the date, time, PID and a sequence number. Alternatively, a filename
can be specified as a parameter on the triggerReport() call.

nodereport.triggerReport("myReportName");

Content of the NodeReport in the initial implementation consists of a
header section containing the event type, date, time, PID and Node version,
sections containing Javascript and native stack traces, a section containing
V8 heap information, a section containing libuv handle information and an OS
platform information section showing CPU and memory usage and system limits.
The following messages are issued to stderr when a NodeReport is triggered:
A NodeReport can also be triggered automatically on unhandled exceptions, fatal
error events (for example out of memory errors), and signals (Linux/MacOS only).
Triggering on these events can be enabled using the following API call:

Writing Node.js error report to file: NodeReport.201605113.145311.26249.001.txt
Node.js error report completed
nodereport.setEvents("exception+fatalerror+signal+apicall");

A NodeReport can also be triggered on unhandled exception and fatal error
events, and/or signals (Linux/OSX only). These and other options can be
enabled or disabled using the following APIs:
Additional configuration is available using the following APIs:

nodereport.setEvents("exception+fatalerror+signal+apicall");
nodereport.setSignal("SIGUSR2|SIGQUIT");
nodereport.setFileName("stdout|stderr|<filename>");
nodereport.setDirectory("<full path>");

Sample programs for triggering NodeReports are provided in the

To see examples of NodeReports generated from these events you can run the
demonstration applications provided in the nodereport github repository. These are
Node.js applications which will prompt you to trigger the required event.
