read csv-data and put it in an array

@Perlchamp said in read csv-data and put it in an array:

how can i see the console.log statements in the browser, starting MM ?
cannot see node_helper messages in browser, must look in the terminal window where u did npm start
you can redirect those messages to a file
npm start >somefile
and then look at somefile live with editor
did i enter the code in the right place?
const csvFilePath = this.path + ‘birthdaylist.csv’;
u have this.path outside the NodeHelper.create, at that time ‘this’ does not exist
‘this’ means ‘instance of’, and u are outside the thing that creates the instance
if I enter the following into the terminal window:

because u are not running in magic mirror , ‘this’ does not exist
node console.log (‘path: $ {this.path}’)

i got an error message:
bash: Syntaxerror unexpected word `(’
what am I doing wrong…
bash would not see any ( unless u put it on the line with node

node (something)
that is a command to bash (the terminal window program, he has his own rules about parens, and other special characters (* means ALL filenames in this folder for example!)

I never ever use $ in node_helper (or anywhere else)
I would do this
console.log (‘path: '+ this.path)

thank you. ok, i will test …

only for your information:

start() {
		console.log(`Starting module helper: ${this.name}`);
	},

	stop(){
		console.log(`Stopping module helper: ${this.name}`);
	},

this is from your SampleModule. i’m not here to reprimand you. it should only be information. so please do not misunderstand.

@Perlchamp thanks… will fix… never copy from another without review!!

always my pleasure

sdetweil · Apr 30, 2020, 4:43 PM

@Perlchamp fixed

if u redirect the output of npm start to a file, this is what you will see in the file

ok, it’s slowly dawning on me, see little light at the end of the tunnel

sdetweil · Apr 30, 2020, 4:55 PM

@Perlchamp if u install the logging module I suggested, then it captures all the messages from the modulename.js in the browser and prints them to the terminal window log, which would be saved to the file as well.

sdetweil · Apr 30, 2020, 5:02 PM

@sdetweil a node_helper has two built in functions (I have never useed init() or stop() for anything, but they are available)

start: when the helper is loaded
socketNotificationReceived, when the modulename.js sends a message to the helper

the helper has one useful function

sendSocketNotification , to send a message back to the modulename.js

everything else is all up to you

note that the modulename.js gets the config.js config:{} info for this module, NOT the node_helper… so if the node_helper needs to know (filenames, timings, ???) , the modulename.js has to send a message with the this.config info down to the helper, and the helper has to save it to use later

@sdetweil said in read csv-data and put it in an array:

so i also can do (?):
npm start dev
in the window on the right klicking on “console”. there i see a lot of massages coming from console/moduls
and then i can use your module to lock out other modules (?) …
