How to declare an array in config.js?

[fischershaw]

How does one declare an array in config.js within the config object? Just using [] does not work. For instance, declaring the following within a module’s config object:

biff: ['muffy','sport','spam']

does NOT create an array. Instead, what is created is the comma separated string: “muffy,sport,spam”.

[bhepler]

@fischershaw - Try double quotes. The " character.

biff: ["muffy","sport","spam"],

Don’t forget the trailing comma.

[fischershaw]

@bhepler Yes, the trailing comma is present. The config.js file is syntactically correct, it just produces unexpected results. In this case a string instead of an array.

@fischershaw @bhepler the way you have done it works for me…

from my MyCovid19 module
in config.js

			config:{
				countries:["Italy","USA","China","Spain", "France",'Sweden'],

in my code

 for(var i in this.config.countries){
        switch(this.config.countries[i].toLowerCase()) {

oh, single or double quotes doesn’t matter, even in the same array, long as they are matched

why do you think it is a string? its an array of strings

• open the developers window, (npm start dev or ctrl-shift-i on the keyboard),

• select the sources tab,

• look thru the items on the left, expand modules, find your module, click its .js file ,

• then put a stop (click on the line edge to the left of the 1st statement after start),

• then hit f5 (refresh page) and the page will be reloaded and the debugger will stop on that statement,

• u can examine the variables in the config object

@sdetweil My dumb error which I corrected. Sorry to bother you.

@fischershaw is ok, we all learn… I just spent 2 hours trying to figure out why an api request failed, 404 not found

I had spelled apikey with an uppercase K…

which debugging approach did you use?
