QUESTION
...ANSWER
Answered 2021-Jun-10 at 23:20I think this looks very similar: https://stackoverflow.com/a/64765671/12431728
Based on the linked answer, I think you have to specify undefined
as a possible type for the prop, so type?: string | undefined
for the prop type definition.
The other option they gave is disabling strict null checking in tsconfig.json by adding "strictNullChecks": false
to compilerOptions
.

Im using Typescript, Electron, Webpack and NodeJS to make a webapp but for some reason the import/export isnt working properly.
The error im receiving is:
"Warning: React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports."
Ive tripled checked my imports and exports and the component is still undefined when its called.

My mistake was thinking that the webpack ts-loader would take context from from ts-config file and transpile the typescript according to that and webpack the content into the final bundle. Upon looking at my question again ive realised i put the index.tsx file as my entry point which is why i was still getting a bundled webpack file but my imports were undefined the only file being webpack was my index file i believe. That combined with the single file output tsc seems to have been the cause.
tsc
was creating a bundle of my typescript.
webpack
was creating a bundle of just my index.tsx file
Problem entry: './src/index.tsx'
& "outFile": "./dist/main.js"

QUESTION
I'm using Application Insights JS SDK React Plugin to log application insights data to Azure. This data publishing could get blocked by some browser extensions such as Ad Blocker, Privacy Badger, etc. In my case analytics got blocked by Privacy Badger while experimenting.
I know it can be prevented by disabling relevant add-ons for the particular site from the browser. Just wondering is there a particular way to prevent this from implementation side without asking users to disable their add-ons.

Answered 2021-Jun-03 at 08:09Have you considered building a proxy to forward traffic to your own domain before then passing it off to App Insights?
https://github.com/shaneochotny/ApplicationInsights-JS-Proxy
Show how to proxy requests from the Application Insights Javascript SDK instead of sending telemetry directly to dc.services.visualstudio.com. This allows you to do things such as use your own custom domain and/or hide the Instrumentation Key.
There are step by step instructions in that link to configure this
QUESTION
I have a react app in typescript that cant compile for unknown reasons. This is the error I get:
...ANSWER
Answered 2021-Jun-01 at 14:52Don't listen to past me, past me was 2 weeks into this problem and couldn't think straight. Felix Kling had it right, I needed the babel preset (@babel/preset-typescript) in my .babelrc.
The reason it seemed to freeze on Files successfully emitted, waiting for typecheck results...
message is because the app was running and if I had checked my browser I would have seen the app. Something I did must have suppressed the warnings I usually see after this message.

Answered 2021-May-24 at 13:01Looks like you are testing the value by reloading the page for each route . When you are refreshing you are rendering a brand new App . So what you need here is to move between the routes without a page refresh.
