Node-RED is now included in Raspbian Jessie.

[Nicholas O'Leary]

Hi,

I teased an announcement last night, but we didn't quite have all the pieces in place for me to share the news - but we do now.

As of the November 2015 Raspbian Jessie image, Node-RED now comes preinstalled on the Raspberry Pi.

Since being made available on the npm package manager last year, we have had over 113,000 installs of node-red - roughly half of those coming from users taking advantage of the boilerplate we make available on IBM Bluemix, with a few hundred more installs happening daily. Of course a proportion of those will be re-installs rather than new installs, but it is certainly a healthy sign.

Coming preinstalled on the Raspberry Pi immediately makes it available to an even wider audience and should prove a great boost to the project.

We've come a long way since Dave and I started Node-RED as a side project. And we certainly haven't finished yet.

Nick

Just a reflection of your great work. Congrats guys.

Congratulations !

I use Node-RED on the Raspberry pi a lot this will make things easier !

[The ThingBox]

Hi,

Just an info:

We have made a ThingBox on a Jessie image some time ago, but didn't released it because we faced many incompatibilities

with third party code..

Nicolas

The ThingBox Project - A ready to flash Raspberry Pi image that contains Node-RED and Internet Of Things software for non developers.

Find it at http://TheThingbox.io

[Mark Setrem]

Fantastic news, congrats!

Having installed it, I'm happily running it and have installed additional nodes without any problems.

Rgds. Mark

[Luis Montes]

Whoa, that is awesome!

Good job guys.

[Nathanaël Lécaudé]

I see there is a node-red-start command now.  What would be the best way to start node-red as a service on boot ?

If you are using this preinstalled version (or have apt-get installed it), then it is already installed as a service, you just need to tell rc.d to start it:

   sudo update-rc.d nodered defaults

Congratulations to the Node-RED team this is an amazing mile stone! 

[Artem Pastukhov]

Thats great!

But why you are using init.d start-up script instead systemd unit?
Where i can find the sources of debian package?

Hi Artem,

Dave did the hard work on this but he's currently off at a client site this week. Once he's back, we'll get the source for the package up on github and let you know.

Currently using init.d as we are not actually installing as a running service. (As not everyone may want Node-RED running by default on their new install... ) so we installed it so it could be enabled simply, but also run using the same script. So the new node-red-start command starts the service and then tails the log file so the user can see the output.

That way we can use the same menu shortcut whether it is stopped, running or running as a service.

This may also be possible with systemd but I'm not yet familiar enough with it, so went with what does the job.

[Julian Knight]

Well done guys, great to see Node-Red being recognised as an important part of the IoT world just like the Pi.

If we can ever get our hands on the new Pi Zero's (sold out already I understand), I predict large numbers of NR instances appearing around the world ;)

I have a zero and plan to test the latest development next week but bear in mind the zero has no Ethernet and is not fast like pi2. I have only moderate ambition for it.

So what version of Raspbian do I need to look for to getbNR built in?

And is password security already in place or does that need adding?

Slight clarification please. Is that included in the November NOOBS version – or do we need to download the separate Raspbian Jessie standalone version?

you end up with the same build of jessie following either route. 

NOOBS just gives you the the simple Operating System installer,  (and the NOOBs Lite version requires you to have a network connection)

But if you already know what you want you might as well just download the standalone Raspbian Jessie

[Toshi Bass]

Pizero needs latest version of NOOBS v1_5_0 dated 21/11/2015 or it will not load. same with Raspbian Jessie needs to be v4 dated 21/11/2015, both include node-red but you need to download npm (sudo apt-get install npm) as its not included

[Julian Knight]

I don't recommend installing npm separately. Last time I tried that, everything went bang! 

You should just ensure that node.js is installed, you will get the correct version of npm to match the version of node.js.

[Dave C-J]

Julian

the preinstall of Node-RED required node.js to be present so it is also already there. 

sudo apt-get install npm   

then does the correct thing - so no need to worry.

It was left out by default as the Pi guys are always worried about space and adding npm drags in a load of extra packages, that while useful to anyone one step beyond beginner, are not strictly necessary to run and get to grips with the Node-RED basics. 

[Nicholas O'Leary]

Julian,

In Raspbian Jessie, node.js and npm are packaged separately and the preinstalled version of node-red depends on just the node.js package. This was done to keep the footprint of the node-red package as small as possible as previously node.js was not preinstalled on the image.

It is good enough to try node-red out and if you want to install additional nodes, as the updated Raspberry Pi docs state, you have to first "apt-get install npm" - this is guaranteed to get you the right version of npm as it is also the version packaged for Raspbian Jessie.

If you want to run with a different version of node.js then, as full explained in our RPi docs, you have to remove the apt installed version of node-red and node.js and (if you had added it) npm, before following the instructions for installing node and the rest. Those instructions should always get you npm installed alongside node.js.

Nick

 inodered package only depends on the nodejs package. It does not depend on the npm package -

Hi Nick, 

            As you can see by my posts I am a real NOOB. I am a frustrated with the Raspbian Jessie img. I thought it was targeted towards people like me...BUT the older version of node.js makes it confusing when trying to install new nodes. I think ALOT of new user are going to hit this road block and get confused. It should be the most current version so it can work with all Nodes. Maybe I'm not understanding this properly. I worked all evening getting my Neurio communicating to emoncms. Now I tried my DHT11 sensor to learn I have to remove everything and reinstall to get the current version of node.js.

[Dave C-J]

As noted in another thread you do see to have hit the perfect bad news combination. We are trying to resolve this now.

The particular node you are trying to add does not fix it's own dependancies to versions that are known to work, instead relying on the underlying author not to make breaking changes... The underlying package meanwhile has been "enhanced" such that it now requires the newer version of node - which then breaks. I have asked the author to "pin" the required version back to an older level that does compile without problems against the node v0.10.x . This then does compile and works fine - I have posted the workaround in the other thread - while we wait for the author to accept the pull request.

[Blue Collar Ingenuity]

Hey Dave, 

                I do now see how everything lined up for me. This hobby is all about learning and that I am :). Thank-you for "work around" I will give it a go tonight.

Hi Nick, 

            I started with a clean img of the pre-installed NR on Jessie with the intention to removing node.js and updating as per the site instructions. I followed these instructions (X2)

To do this you must uninstall the built-in version and re-install using the instructions below. To uninstall:

sudo apt-get remove nodered
sudo apt-get remove nodejs nodejs-legacy
sudo apt-get remove npm   # if you installed npm

This will remove all the built in packages but leave your workspace - by default at ~/.node-red . You may then proceed to re-install as per instructions below.

and 

Raspberry Pi 2

To install Node.js on Pi 2 - and other Arm7 processor based boards, run the following commands:

curl -sL https://deb.nodesource.com/setup_0.12 | sudo bash -
sudo apt-get install -y build-essential python-dev python-rpi.gpio nodejs

and 

Install Node-RED

The easiest way to install Node-RED is to use node’s package manager, npm:

sudo npm install -g --unsafe-perm  node-red

When I run 

node-red-pi --max-old-space-size=128

I get the following error

pi@raspberrypi:~ $ node-red-pi --max-old-space-size=128

/usr/lib/node_modules/node-red/node_modules/fs-extra/lib/mkdirs/mkdirs-sync.js:39

          throw err0

    at Function.Module._load (module.js:310:12)

    at Function.Module.runMain (module.js:501:10)

Any Idea ?? I think I'm starting to become a PIA

Well, the error message says it all:

Your disk is full!

What size SD card are you using? Can you share the  output of the command 'df'?

Is that a 4GB SD card?

(Will pick this up in the morning.)

[Blue Collar Ingenuity]

Thanks Nick, 

                    It's a 16GB card, I keep installing the new images with win32dsk imager. Should I be reformatting the card first ?

Jeff  

[Luis Montes]

not sure about jessie, but on the previous version you had to run raspi-config on the pi to expand the partition to use the full card.

[Mark Setrem]

Same in Jessie.

You need to run

sudo raspi-config

I've only recently started to use it but I'm already building pretty sweet stuff with it :)

So congratulations on the distro include! ... Its most definitely well deserved.
