QUESTION
I'm trying to understand how parallelization works in Durable Function. I have a durable function with the following code:
...ANSWER
Answered 2021-Jun-10 at 08:44There are two approaches that are possible. The first is to use a suborchestrator for each job so that each suborchestrator handles just a specific job. Here is the docs for this approach https://docs.microsoft.com/en-us/azure/azure-functions/durable/durable-functions-sub-orchestrations?tabs=csharp Example from docs seem to be alike to yours.
The other is to use ContinueWith so that each job has its own "chain"

QUESTION
I'm using React and Next.js with Firestore. On one page I get data from Firebase with useEffect only once the page is rendered. But since the get is kind of costly (lots of read), I want to persist the data fetched even when the user navigates to other pages and back to this page, so that I don't need to fetch again. How can I do that? Thanks!
...ANSWER
Answered 2021-Jun-15 at 19:03There are multiple ways but one good way would be to use Context, create a data store context which would store your data and then you can read from it as a single source of truth.

I need a cloud function that triggers automatically once per day and query in my "users" collection where "watched" field is true and update all of them as false. I get "13:26 error Parsing error: Unexpected token MyFirstRef" this error in my terminal while deploying my function. I am not familiar with js so can anyone please correct function. Thanks.
...ANSWER
Answered 2021-Jun-15 at 16:13There are several points to correct in your code:
- You need to return a Promise when all the asynchronous job is completed. See this doc for more details.
- If you use the
await
keyword, you need to declare the functionasync
, see here. - A
QuerySnapshot
has aforEach()
method - You can get the
DocumentReference
of a doc from theQuerySnapshot
just by using theref
property.
The following should therefore do the trick:
QUESTION
I want to create components dynamically with custom Refs , and I want to use those refs and use with functionalities like measure() etc.
I created following code
...ANSWER
Answered 2021-Jun-15 at 19:50- Yes, React refs need to be forwarded when using functional components.
- You can't use the
useRef
hook within the loop.
Fix creating the refs. Use a React ref to hold an array of created refs, and pass them by mapped index.
QUESTION
I'm writing a Firebase function (Gist) which
Queries a realtime database ref (events) in the following fashion:
await admin.database().ref('/events_geo').once('value').then(snapshots => {
Iterates through all the events
snapshots.forEach(snapshot => {
Events are filtered by a criteria for further processing
Several queries are fired off towards realtime DB to get details related to the event
await database().ref("/ratings").orderByChild('fk_event').equalTo(snapshot.key).once('value').then(snapshots => {
Data is prepared for SendGrid and the processing is finished
All of the data processing works perfectly fine but I can't get the outer await (point 1 in my list) to wait for the inner awaits (queries towards realtime DB) and thus when SendGrid should be called the data is empty. The data arrives a little while later. Example output from Firebase function logs can be seen below:
10:54:12.642 AM Function execution started
10:54:13.945 AM There are no emails to be sent in afterEventHostMailGoodRating
10:54:14.048 AM There are no emails to be sent in afterEventHostMailBadRating
10:54:14.052 AM Function execution took 1412 ms, finished with status: 'ok'
10:54:14.148 AM
Super hyggelig aften :)
super oplevelse, ... long string generated
Gist showing the function in question
I'm probably mixing up my async/awaits because of the awaits inside the await. But I don't see how else the code could be written without splitting it out into many atomic pieces but that would still require stitching a bunch of awaits together and make it harder to read.
So, two questions in total. Can this code work and what would be the ideal way to handle this pattern of making further processing on top of data fetched from Realtime DB?

I want to collect the names (Jenny, Tiffany, etc.) that are stored in every object. and these objects live in an array. I've used Array.prototype.every()
and Array.prototype.forEach()
, but I don't think they are the right methods.
I also want to note that majority of these codes are from Codaffection. I am practicing on developing in React.
If you would like to experiment with the code, click here.
In every object, there is an id, fullname, email and etc.
This is the code that adds, edits, generates unique ids for each employee, and gets all storage data.

QUESTION
I wish to suggest (perhaps enforce, but I am not firm on the semantics yet) a particular format for the output of a PowerShell function.
about_Format.ps1xml (versioned for PowerShell 7.1) says this: 'Beginning in PowerShell 6, the default views are defined in PowerShell source code. The Format.ps1xml files from PowerShell 5.1 and earlier versions don't exist in PowerShell 6 and later versions.'. The article then goes on to explain how Format.ps1xml files can be used to change the display of objects, etc etc. This is not very explicit: 'don't exist' -ne 'cannot exist'...
This begs several questions:
- Although they 'don't exist', can Format.ps1xml files be created/used in versions of PowerShell greater than 5.1?
- Whether they can or not, is there some better practice for suggesting to PowerShell how a certain function should format returned data? Note that inherent in 'suggest' is that the pipeline nature of PowerShell's output must be preserved: the user must still be able to pipe the output of the function to Format-List or ForEach-Object etc..
For example, the Get-ADUser
cmdlet returns objects formatted by Format-List
. If I write a function called Search-ADUser
that calls Get-ADUser
internally and returns some of those objects, the output will also be formatted as a list. Piping the output to Format-Table
before returning it does not satisfy my requirements, because the output will then not be treated as separate objects in a pipeline.
Example code:
...ANSWER
Answered 2021-Jun-15 at 18:36Although they 'don't exist', can
Format.ps1xml
files be created/used in versions of PowerShell greater than 5.1?
Yes; in fact any third-party code must use them to define custom formatting.
- That
*.ps1xml
files are invariably needed for such definitions is unfortunate; GitHub issue #7845 asks for an in-memory, API-based alternative (which for type data already exists, via theUpdate-TypeData
cmdlet).
- That
It is only the formatting data that ships with PowerShell that is now hardcoded into the PowerShell (Core) executable, presumably for performance reasons.
is there some better practice for suggesting to PowerShell how a certain function should format returned data?
The lack of an API-based way to define formatting data requires the following approach:
Determine the full name of the .NET type(s) to which the formatting should apply.
If it is
[pscustomobject]
instances that the formatting should apply to, you need to (a) choose a unique (virtual) type name and (b) assign it to the[pscustomobject]
instances via PowerShell's ETS (Extended Type System); e.g.:For
[pscustomobject]
instances created by theSelect-Object
cmdlet:
