It is not usually recommended to reuse errors since the stack trace is attached whenever the error is instantiated.

However in some cases the overhead of doing that may affect performance, especially if the error is an exception that is known to occur frequently and is handled.

Only in these cases it may be advantagous to reuse the created Error. In all other cases getting a full stacktrace created at the time the exception occurs is to be preferred as it gives much better information needed to debug the problem.

Run

➝ node errors.js

This is specifically tailored to Node.js binding projects in which case the C++ layer is always a library.

Clone gyp:

git clone --depth 1 https://chromium.googlesource.com/external/gyp.git gyp

Add the below common.gypi file in the root of the project.

A quick overview of the node.js streams interface with basic examples.

This is based on @brycebaril's presentation, Node.js Streams2 Demystified

Overview

Streams are a first-class construct in Node.js for handling data.

Think of them as as lazy evaluation applied to data.

	# Combined all static libaries in the current directory into a single static library
	# It is hardcoded to use the i386, armv7, and armv7s architectures; this can easily be changed via the 'archs' variable at the top
	# The script takes a single argument, which is the name of the final, combined library to be created.
	#
	# For example:
	# => combine_static_libraries.sh combined-library
