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”.

@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?
