meta-nodejs

OpenEmbedded layer for latest Node.js releases.

ℹ️ As an official extension of this layer, installing meta-nodejs-contrib is highly recommended for community contributed Node.js based package recipes and Bitbake helper classes.

Node.js releases

  • Current 7
  • LTS 6
  • Maintenance 4
  • End of life 0.12
  • End of life 0.10
  • End of life 0.8

LTS Schedule

Dependencies

meta-nodejs depends on following layers:

Cross-compiling for 32-bit target on 64-bit host

Node.js v7+ ships with V8 v5.5+ that requires native (host) compilation of some internal build tools (mkpeephole and mksnapshot). These internal tools must be built with "bitness" matching the cross-compilation target (eg. 32-bit ARM).

If you encounter build errors related to mkpeephole or mksnapshot you most likely need to install appropriate multilib compilers and libraries to to your host system.

Example

Prerequisites for compiling for 32-bit ARM with x86_64 Ubuntu 16.04 Xenial (or newer):

sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install g++-multilib libssl-dev:i386 libcrypto++-dev:i386 zlib1g-dev:i386

Available Packages

  • nodejs
  • nodejs-npm
  • nodejs-dtrace
  • nodejs-systemtap
  • nodejs-wafadmin (only with Node.js 0.8)

Installation

Layer installation varies depending on your OpenEmbedded distribution. These instructions are generic.

  1. Fetch meta-nodejs layer from https://github.com/imyller/meta-nodejs.git

  2. Add meta-nodejs layer to EXTRALAYERS in conf/bblayers.conf. For example:

    	EXTRALAYERS +=" \
    		${TOPDIR}/sources/meta-nodejs \
    	"
    

Recommended layers

As an official extension of this layer, installing meta-nodejs-contrib is highly recommended for community contributed Node.js based package recipes and Bitbake helper classes.

Usage

Building Node Packages

To build latest stable Node.js package:

	bitbake nodejs

Node.js as a dependency

Add Node.js as a dependency in recipe with RDEPENDS (for runtime) or DEPENDS (for build):

	DEPENDS += " nodejs"
	RDEPENDS_${PN} += " nodejs"

npm install buildable recipes

Inherit npm-install build task class in your recipe.

Bitbake classes

meta-nodejs layer adds few Node.js related helper classes.

npm-base class

npm-base class defines following functions:

  • oe_runnpm: call cross-compiling npm
  • oe_runnpm_native: call native-compiling npm

For example:

  inherit npm-base

  do_install() {
	oe_runnpm install     # Installs dependencies defined in package.json
  }

Variables

  • NPM_FLAGS: Extra command line arguments for npm calls made by oe_runnpm()
  • NPM_ARCH: Override npm target architecture (defaults to TARGET_ARCH)
  • NPM_REGISTRY: override npm registry URL

npm-install class

npm-install class inherits npm-base class and adds following build tasks (listed in their run order):

  • npm_install: runs npm install in source directory
  • npm_shrinkwrap: runs npm shrinkwrap in source directory
  • npm_dedupe: runs npm dedupe in source directory

You can disable one or more of these build tasks in the recipe with do_<taskname>[noexec] = "1":

  do_npm_shrinkwrap[noexec] = "1"

Variables

  • NPM_INSTALL_FLAGS: Extra command line arguments for npm calls made in npm_install task
  • NPM_INSTALL: Parameters for npm install command (such as specific package names)

npm-install-global class

npm-install-global class inherits npm-base class and installs the selected package globally. This is done in the do_install task of the class.

Variables

  • NPM_INSTALL_FLAGS: Extra command line arguments for npm calls made in do_install and do_configure task
