hello - i'm having some troubles with 
getObject
and JSON encoded strings. The error is 
Property 'getObject' does not exist on type 'string'.ts(2339)
. Any suggestions on this? I'll leave my code sample in a thread
Copy code
export let testConfig = config.get("testConfig") || "\"{testConfig\": \"test\"}";
let getConfig = testConfig.getObject(testConfig);

so, question: i'm unfamiliar with 'getObject' (and i can't find any docs on it).
What are you expecting to have happen there?
however, you called .getObject on a string.
what you want to do is 
config.getObject
not 
testConfig.getObject
.
Note: typescript will def help you out here 🙂

hmm so it actually gets a bit more complicated than that
so in my 
config.ts
i've got
Copy code
let newrelicConfig = new pulumi.Config("newrelic");
export let newrelicAlertChannels = newrelicConfig.get("alertChannels") || "{\"alertChannels\":[{\"name\":\"slack\"}, {\"name\":\"pagerduty\"}}
im then importing 
config.ts
into a new file
where i'm trying to do this
Copy code
import * as config from "../config";
import { AlertChannelArgs } from "@pulumi/newrelic";

export interface NewRelicAlertChannel {
    name: string,
    type: string,
    configuration: AlertChannelArgs,
}
export const newrelicAlertChannels = config.newrelicConfig.getObject<Array<NewRelicAlertChannel>>("alertChannels");

Ok 🙂

or is there any easy why to use an array of values from yaml with pulumi config files?

so all .getObject does is read out the string value, and then call JSON.parse on it
what sort of error are you getting with the above?

Copy code
Property 'getObject' does not exist on type 'string'.ts
when i set the json encoded string as default within config.ts

can you link me to your code?
it looks like you're simply calling .getObject on a string, not on hte real config object.
but it's hard to tell given what i can see so far.

sounds good!

07/01/2019, 7:06 PM
so here's what i have based on previous suggestions
in 
config.ts
Copy code
export let newrelicAlertChannels =  newrelicConfig.get("alertChannels") || "\"{alertChannels\": [{\"name\":\"slack\"}, {\"name\":\"pagerduty\"}]}";
l

lemon-spoon-91807

07/01/2019, 7:07 PM
ok. so that's just exporting a string.
q

quaint-queen-45003

07/01/2019, 7:07 PM
yup then in a different file
Copy code
import { newrelicAlertChannels } from "../config";

export interface NewRelicAlertChannel {
    name: string,
    type: string,
    configuration: AlertChannelArgs,
}
 
export const alertingChannels= newrelicAlertChannels.getObject<Array<NewRelicAlertChannel>>("alertChannels");
l

lemon-spoon-91807

07/01/2019, 7:08 PM
right. you're importing a string, and callin .getObject on it 🙂
q

quaint-queen-45003

07/01/2019, 7:08 PM
and the error is
Copy code
'getObject' does not exist on type 'string'.ts

one way you could address this (not necessarily teh best way)is to simply do this:
export const alertingChannels = JSON.parse(newrelicAlertChannels)
note: the issue you're runnign into above is not really a pulumi issue 🙂 it's something that would't work in JS at all. it's equivalent to:
Copy code
file1.js
export let foo = "[1, 2, 3]";

file2.js
import foo from "file1";
let bar = foo.getObject("x");
does that make sense? 🙂

ya it makes sense. i guess i'm confused why 
getObject
works when pulling same string from config files
l

lemon-spoon-91807

07/01/2019, 7:13 PM
because you're calling it on a 
pulumi.Config
object
i.e.
Copy code
let newrelicConfig = new pulumi.Config("newrelic");
export let newrelicAlertChannels = newrelicConfig.get("alertChannels")

bah i see
thanks 🙂
l

lemon-spoon-91807

07/01/2019, 7:13 PM
in this case, 
.get
(or 
.getObject
) is being called on a Config object, not a string
great! 🙂

Thanks for the help. Im new to JS and it still bites me sometimes 🙂

absolutely! 🙂
i recommend TypeScript 😄
it helps a lot for these types of things
