npm-arch-dependencies v0.1.0

archpm:

Install npm dependencies based on the OS CPU architecture.

Getting Started

Install the module with: npm install npm-arch-dependencies.

Specify your dependencies inside package.json

List the specific dependencies for each platform in your package.json, in the form of os.arch() + 'Dependencies'.

To include raspi-io and johnny-five in arm only:

"armDependencies": {
    "johnny-five": "latest",
    "raspi-io": "latest"
}

Then run:

archpm

If you are running the command on a Raspbery Pi archpm will install raspi-io and johnny-five.

npm install

Add archpm to the scripts section of package.json

{
    "scripts": {
        "postinstall": "archpm",
        "start": ...
    }
}

Code

In your source code, make sure you are as well importing code based on your architecture.

For example:

const arch = require('os').arch();

class Button {
    constructor(config={pin:8}){
        if(arch === 'arm'){
            const five = require('johnny-five');
            this.relay = new five.Relay(config);
        } else {
            this.relay = {
                open: function(){},
                close: function(){}
            };
        }
    }
}
