meta-nodejs

OpenEmbedded layer for latest stable Node.js releases.

Installation

1. Add meta-nodejs layer to sources/layers.txt

     meta-nodejs,git://github.com/imyller/meta-nodejs.git,master,HEAD
   

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

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

3. Run oebb.sh update

Usage

Building Node.js package

1. To build latest stable Node.js package:

    bitbake nodejs

Node.js runtime as a dependency

Add Node.js as a dependency in recipe:

    RDEPENDS_${PN} += "nodejs"

npm install buildable recipes

Inherit npm or npm-install build task classes in your recipe.

Bitbake classes

meta-nodejs layer adds two new classes: npm and npm-install.

npm class

npm defines the oe_runnpm command which will call cross-compiling npm.

For example:

  inherit npm
      
  do_install() {
    oe_runnpm install     # Installs dependencies defined in package.json from in source directory to node_modules
  }

Variables

You can define extra command line arguments for npm calls made by oe_runnpm() by appending them to NPM_FLAGS variable.

npm-install class

npm-install class inherits npm 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

• You can define extra command line arguments for npm command by appending them to NPM_INSTALL_FLAGS variable.

• you can define parameters for npm install command (such as specific package names) by appending them to NPM_INSTALL variable.
