Answered 2021-Mar-28 at 19:01I'll try to break it up as much as possible, but there are plenty of things to be done.
- As per the documentation, when working with Flutter Web and Firebase, you need to add your Firebase dependencies in your index.html, like this:
Use the dependencies that you want, but if you aren't using analytics, leave it out. You have to import this first thing though firebasejs/8.3.0/firebase-app.js
QUESTION
I've got a problem in my NestJs app. Project was running perfect until yesterday.
Apparently my node.js upgraded from 14.16.1
to 14.17.0
. So I changed this version number in my engines
object, in package.json
. I executed yarn install
again, to make sure everything was there, and tried yarn start:dev
(which translates to nest start --watch
).
But my app isn't running =( It seems like there's something wrong regarding my apollo-server-fastify:
...ANSWER
Answered 2021-Jun-01 at 05:58A temporary fix, until this issue is addressed by maintainers, is to copy this patch file into your repository, then modify your package.json to use the following:
"@nestjs/graphql": "patch:@nestjs/graphql@7.10.6#[YOUR/LOCAL/PATH]/graphql.patch"
I ran into this same issue with my project. I'm not sure about the origin, but I did see that apollo-server-fastify
was updated to 3.0.0-lambda.0 about 5 days ago and to 3.0.0-preview.0 a few hours ago.
I tracked the possible fix down to the registerFastify
method in @nestjs/graphql
. The solution, I believe, is to call await apolloServer.start()
on line 228 in lib/graphql.module.ts
before the Apollo Server's createHandler()
method is called. I opened an issue on the repository with more details, which you can follow until resolved.
I implemented the fix in the template repository I'm working on with yarn patch @nestjs/graphql
. The repository is available on the dev-nx
branch at troncali/nest-vue. The patch is located in ./.yarn/patches/@nestjs/graphql.patch
.
QUESTION
I wonder why the IntelliJ Add import statement
works differently when used in a spec file:
The setup is very simple.
In the project tsconfig.base.ts
file we specify a path:
ANSWER
Answered 2021-Jun-03 at 15:03With Use path mappings from tsconfig.json set to Always, the IDE tries to use the mappings any time the import is added. But, as "@idea-import-spec/data"
is mapped to libs/data/src/index.ts
that, in turn, re-exports everything from lib/data.ts
, adding a mapped import to data.ts
would result in a circular dependency - that's why a relative path is used. But data.spec.ts
is not re-exported in barrel, so using a path mappings there looks safe

Been getting this error when running 'ng build' on my Angular 12.0.2 project
...ANSWER
Answered 2021-Jun-02 at 17:41We figured it out. As you can see in our packages.json

fixed the issue.
QUESTION
any suggestions how to debug null errors in flutter with null safety ?
Expected a value of type 'Map', but got one of type 'Null'
just in case I replaced all Map I have in my code with Map? but error continues
and thanks to the stupid way null safety is implemented the 675 lines of error stack(the one below is just the first 300) dos not contain a single one that contains information where in the Dart code the error originates.
I'm 99% sure the error is caused by a communication request but the error is happening before I get a response from my call to the server and is not even getting to a place to convert a Map object
unfortunately that is not the first time the new flutter NULL safety failed to provide a proper debug information with a NULL object error but so far I managed to fix them by reducing the executable code to the point of identifying the problem
...ANSWER
Answered 2021-May-31 at 14:18so a solution to the problem does not exist, the debugger will not provide relevant information for the origins (the dart file) of the error. But thankfully the particular problem is only in the latest version of the DEV channel (Flutter 2.3.0-16.0.pre & Dart 2.14.0 (build 2.14.0-136.0.dev)) and all works fine in the master chanell so I no longer need proper (usable) stack trace from the debugger to fix it.

This converter follows the rules of rfc4180.

I am writing an react-electron application and I noticed that when I used electron-builder to build it the binary was stuck when calling "spawn".
With "yarn start" the application can be executed without problems. Only with electron-builder it gets stuck.
Can you help ?
Thanks,
Update
It seems that the C++ binary included as part of the program can't be executed within electron. If I give the hardcoded full path to the binary it works but if I give the path from __dirname I get an error
...ANSWER
Answered 2021-May-17 at 09:56By default, Electron Builder compiles your application and packs all resources into one large archive file (think of it as a ZIP file) which can be read just fine because Electron brings support for this format known as "ASAR".
When running the built program, the code will be read from the archive. This means that __dirname
will point to a directory inside the archive. The operating system, however, cannot read from the archive. Since you did not actually include the piece of code calling child_process.spawn ()
, I can only speculate on why you get ENOTDIR
, which hints that a given path is not a directory when it was expected to be one, but I assume this is because you point to a path inside the ASAR file.
When relying on external binaries, it is a good idea to keep them outside the ASAR archive and programmatically find the path to them (which is quite complex) or by preventing Electron Builder from compiling your app into an ASAR file. However, you would also have to ask Electron Builder to include the executable in the built version of your app. This can be done by modifying your package.json
