Installing Node-RED:

https://www.npmjs.com/package/node-red

I found this quick guide https://www.npmjs.com/package/node-red#quick-start. and installed Node-RED with the following command:

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

npm install node-red-node-google

I found this thread: https://github.com/npm/npm/issues/13525

I still get the error, but running the following command, showed that node-red is not dependand on version:

npm ls minimatch

I then found this thread, and ran the following commands:

Which still didn't remove the warning, so I tried the following command from the same thread:

npm update -g [email protected]

Which still didn't remove the warning, so I tried the following command from the same thread:

Following a comment on this GitHub issue,

I then decided to uninstalle the google module, using the following command

npm uninstall node-red-node-google --save

Got the following result:

I still got the warning - but this time the Google Module turns up in Node-RED.

I then prepared the API by completing the following Pre-requisites:

You must enable the Google APIs.

In the Google Developer Console under "Api & auth" select "APIs"

Search for "Directions API" click on it and then click "Enable API"

Create credentials: and got an API key (listed below)

The key can be restricted later if needed, floowl this link:

https://console.developers.google.com/apis/credentials/key/130?project=calendar-integration-201607&authuser=1&folder&organizationId

I created a project:

Name: Calendar integration

project ID will be calendar-integration-201607

API key: AIzaSyDLFG2zsrU0NZfu8cHFDnyoW0Y58pU5YNg

node-red

And openedhttp://localhost:1880

Create your own project by following these instructions

Please configure the authorized Redirect URIs of your app to include the following url:

http://localhost:1880/google-credentials/auth/callback

Here is your client ID

611841483681-3dkmih3ou59lr6geqvdsk0v28qma6chr.apps.googleusercontent.com

Here is your client secret

1VzdQOgcslce6afpGE8JOpLD

When pressing authorisation with Google - I got the following message:

auth worked but profile fetching failed

Google search led me to this issue on GitHub -after which I enable the Google+ API in Google's developer console:

https://github.com/node-red/node-red-web-nodes/issues/206

I retried the authoriztion, and got following succes message:

Authorised - you can close this window and return to Node-RED

I entered name of the calender - and deployed the workshpace.

I decided to also add a trigger for the event (an incomming mail)

And added app specific password (to my icloud mail)

After some investigation

https://stackoverflow.com/questions/41505374/read-google-calendar-date-and-title-in-node-red?rq=1

I ended on this side:

https://flows.nodered.org/node/node-red-contrib-google

And decided to install the following code, that as mentioned on the page: "contains two nodes. There is configuration node made for maintaining connection to Google API Services (google-conn) and regular node providing posibility to call any method of any API exposed via official Google's Node.js Client."

cd /Users/nicolaisens/.node-red

npm install node-red-contrib-google

I got some warnings, but tried to open anyways:

npm WARN deprecated [email protected]: Use uuid module instead

npm WARN [email protected] No repository field.

npm WARN [email protected] No license field.

+ [email protected]

added 75 packages from 62 contributors in 7.373

Opening node-red:

node-red

And openedhttp://localhost:1880

With the following error:

google-credentials:5e90b550.9181cc] 1. failed attempts.

I added the Google Node and created a new service account.

Service account name: Calender Integration

Role: Owner

Service account ID: calender-integration (Calendar integration-f13e39cfe5c2.json)

Key type: JSON

ID: f13e39cfe5c22774136699c148804f081efb9687

Add Google Node

Add Inject node:

As mentioned on this page (https://stackoverflow.com/questions/41505374/read-google-calendar-date-and-title-in-node-red?rq=1\ I then passed "the "calendarId" into the node as a json: {"calendarId" : "<your cal id goes here>"}"... into an inject node to inject this input into the "google" node".

{"calendarId" : "[email protected]"}

Debug gave the following error:

"Error: Access Not Configured. Calendar API has not been used in project 611841483681 before or it is disabled. Enable it by visiting https://console.developers.google.com/apis/api/calendar.googleapis.com/overview?project=611841483681 then retry. If you enabled this API recently, wait a few minutes for the action to propagate to our systems and retry."

So I added the following to the "uthorized redirect URIs:"

https://www.googleapis.com/auth/calendar

https://www.googleapis.com/auth/calendar.readonly

That didn't work, so I added the Google Calender API (as menitioned in the error message;-)

Didn't work at once, so I added the following to to URI - and then it works:

https://www.googleapis.com/calendar/v3

Free / Busy Code:

https://developers.google.com/calendar/v3/reference/freebusy/query?authuser=1

Select string

Create string using Google API: https://developers.google.com/calendar/v3/reference/events/get
