I am re-writing an existing js app into angular and ts. I have a json data file that I read as part of the startup of the existing js app and it works fine. When I try and read the exact same file with the exact same line of code in angular, ts/angular barfs all over it. Here is the code from the existing app:
aircraftData = JSON.parse(data);
and the console log is empty. Here is the the code from the new angular version of the app:
const content = require('./shared/imeiXref.json');
console.log("IMEI=",content[0].IMEI);
and the console output:
AppComponent_Host.ngfactory.js? [sm]:1 ERROR SyntaxError: Unexpected token o in JSON at position 1

Is JSON expected to be in a different format from js to angular/ts?
Thanks....
It was actually already working. I didn't realize that when I read the file in I was already able to parse the JSON by field name so I don't even need to run JSON.parse.

But when paste the API link (what's mention in above in https.get method) in chrome I get the json data successfully. Then why not i getting the json data in terminal?
I have a re-frame project, and my events, subs and db cljs files are populated. I use these three in my project and it works well. But I created a test file, and called subscribe and dispatch in it like so:
(deftest category-filter-test
(dispatch [:add-filter "cat"])
(is (= #(subscribe [:filters]) ["cat"]))
)
And that doesn't work. I get
#object[Error Error: No protocol method IDeref.-deref defined for type undefined: ]
On the other hand, if I try to run subscribe in the shadow-cljs repl, I get the following error:

There doesn't seem to be any existing questions on this topic.
Any ideas?
Just add json loader to your webpack config.
I have a string which I would like to turn into an object so I can pass it to mongoose
string = "{setting: {foo: false}}"
options = JSON.parse(string)
but this is giving me this error
SyntaxError: Unexpected token s

The JSON isnt right.
strthing ='{"setting": {"foo": false}}';
options = JSON.parse(strthing);
alert(options.setting.foo); ----> False.
