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
.

ANSWER
Answered 2021-Jun-14 at 11:45I solved this issue https://github.com/wotamann/vuetify-form-base/issues/50 In the SSR mode form didn't render correctly!
Solution1:
You should use the 'v-mask' package and import the main component file in the vuetify-form-base package.
You should export this package in a plugin like as below: Vue.component('VueMask', () => import('v-mask'))
after that add the main file component to your project:
https://github.com/wotamann/vuetify-form-base/blob/master/dist/src/vFormBase.vue
Alternative solution:
- You can use the https://www.npmjs.com/package/vuetify-form-base-srr package.
QUESTION
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 am new to node/npm
, react
and react-native
so very new to react-native-web
as well. It's been 3 days for me to integrate react-native-web
in a Hello World App generated using npx react-native init
as per the doc. I tried using both templates: with and without typescript, but no success so far. The farthest I got is to run the app code written in index.web.js
but if I add any component from ./src/components/
then I get errors, mostly of webpack.
I created a test repo for easy regeneration of error, So Steps to reproduce are as below:
- Download this repo in your system.
npm install
npm run web
Now you'll see the error in the terminal.
Versions:
- metro-react-native-babel-preset: 0.66.0
- node: 16.3.0
- npm: 7.8.0
- OS: Windows 10 - 64 bit
I followed official documentation but with webpack@^4
and referred this article and somehow managed to reach the below situation:
- Webpage is getting rendered if my whole code is inside
index.web.js
. - But when I import
App
inside this then I get compilation failed due to loader error.

Answered 2021-Jun-12 at 15:49Finally, It's been resolved, my Hello World is done.
These 2 replies from the maintainer himself (@necolas) on this discussion helped me to get the issue.
Reply 1 by @necolas This line in the stack trace is telling you that you're trying to bundle RN internal code in your web bundle: node_modules/react-native/Libraries/NewAppScreen/index.js.
First, you should not be loading any of the RN package on web, especially not parts that aren't part of the public API . Second, as mentioned in the inline comments of the config you pasted above, you need to explicitly list everything in node_modules that needs compiling.

QUESTION
As far as I know, the v8 engine is based on ECMAScript language specifications, do you develop it with a new ECMAScript whenever a new ECMAScript is released?
Or do we add only the newly added functions?
For example, if you look at ES5 -> ES6, in the case of Execution Context, the components change, but do you change all of them?
...ANSWER
Answered 2021-Jun-10 at 09:51(V8 developer here.)
Both the ECMAScript standard itself and engines' implementations of it evolve by adding individual features one by one.
The "TC39" committee discusses new proposed features. Once a feature has been agreed upon, it is added to the standard (see the "Process" document @Bergi linked in his comment for more details). The yearly "releases" of ECMAScript are just snapshots of this continuous process.
Engines typically implement a new feature either shortly before it is finalized (so that implementation feedback can inform the standardization discussion) or shortly after.
Rewriting an entire JavaScript engine from scratch every year would be a huge waste of effort: most of the language doesn't change. Also, rewriting an entire JavaScript engine from scratch would take many years. (In fact, rewriting any software from scratch is almost always a bad idea, because you'll spend a huge amount of time just catching up with what the old version was able to do. Incremental improvements are almost always the better strategy.)
The majority of engine developers' time is typically spent on improving support for existing features and subsystems (compilers, garbage collectors, internal object model, ...), such as making them faster or more memory efficient.
QUESTION
Over many years I've struggled with this same issue. I cannot seem to work out how to use a JavaScript library from TypeScript, reliably.
I seem to get it working by accident and then move on and not revisit such code for years until a extrinsic change forces a breakage, like today when I updated VS 2019.
I've spent days reading about modules and requires and loaders, but I get more and more confused.
Example. I want to use DayJS in a TypeScript .ts
file I am writing.
Here's the sample code.
...ANSWER
Answered 2021-Jun-04 at 18:38I share many of the same frustrations! It's so hard to get Typescript working nicely with Javascript and the microsoft documentation is so obtuse!
In your case : the path to a library is always looked for in node_modules
so in that case you don't need to add the full path.
You also never need to import
a .d.ts
file. You can just put the .d.ts
file somewhere in your working folder and VS Code will detect it.
If you have the .d.ts
file for moment.js
, you will get type completion in VS Code. You don't need to import moment.js
when you load it with a

QUESTION
I have a vaadin14 application that I want to enable different types of authentication mechanisms on different url paths. One is a test url, where authentication should use DB, and the other is the production url that uses keycloak.
I was able to get each authentication mechanism to work separately, but once I try to put both, I get unexpected results.
In both cases, I get login page, but the authentication doesn't work correctly. Here's my security configuration, what am I doing wrong?
...ANSWER
Answered 2021-Jun-06 at 08:12Navigating within a Vaadin UI will change the URL in your browser, but it will not necessarily create a browser request to that exact URL, effectively bypassing the access control defined by Spring security for that URL. As such, Vaadin is really not suited for the request URL-based security approach that Spring provides. For this issue alone you could take a look at my add-on Spring Boot Security for Vaadin which I specifically created to close the gap between Spring security and Vaadin.
But while creating two distinct Spring security contexts based on the URL is fairly easy, this - for the same reason - will not work well or at all with Vaadin. And that's something even my add-on couldn't help with.
Update: As combining both security contexts is an option for you, I can offer the following solution (using my add-on): Starting from the Keycloak example, you would have to do the following:
- Change
WebSecurityConfig
to also add your DB-basedAuthenticationProvider
. Adding yourUserDetailsService
should still be enough. Make sure to give every user a suitable role. - You have to remove this line from
application.properties
:codecamp.vaadin.security.standard-auth.enabled = false
This will re-enable the standard login without Keycloak via a Vaadin view. - Adapt the
KeycloakRouteAccessDeniedHandler
to ignore all test views that shouldn't be protected by Keycloak.
I already prepared all this in Gitlab repo and removed everything not important for the main point of this solution. See the individual commits and their diffs to also help focus in on the important bits.
