kandi X-RAY | HackerNews Summary
A .NET MAUI app for displaying the top posts on Hacker News. This app demonstrates how to use IAsyncEnumerable + C# 8.0 to improve performance. Thanks to IAsyncEnumerable, the items are added to the list as soon as they're available making the app feel faster and more responsive. This app also uses the Text Analytics API from Microsoft Cognitive Services to analyze the sentiment of each headline.

QUESTION
I have my Java server setup with all the appropriate packages (API, DAO, model, service, etc.). On the Hacker News (HN) website they explain that I should use Firebase to call their API.
Do I need to configure Firebase to access all the HN articles from the API, even though I have access to Java's built-in API call functionalities?
I can retrieve one article and see the JSON data in Postman:
...ANSWER
Answered 2021-Oct-18 at 00:20You don't have to use the Firebase SDK to interact with the API, although you can if you want to. Using the Firebase SDK gets you minor performance gains, at the cost of some more implementation complexity. But you can also just make requests to the API endpoints using a normal HTTP client using the API endpoints listed in the documentation (like https://hacker-news.firebaseio.com/v0/item/8863.json).
QUESTION
Here is what I've done so far: There is an API (Hacker News - https://github.com/HackerNews/API) from which I send a GET request from my Java program and retrieve the data. I am able to parse the (JSON) data so that it can be manipulated by the JDK.
Here is what am trying to do next: I want to have my Java program/server communicate with my React application so that React can retrieve the parsed JSON data and display it on a webpage.
Confusion: How do I have React get the data? Do I set it up so that it sends a GET request from my Java server? I have consulted more tutorials than I can count, but I am simply not understanding how to do it.
My code can be found here https://github.com/EmekaEnshinyan/HackerNews-API-Design-Back-End
...ANSWER
Answered 2022-Feb-21 at 14:06Your React application is the frontend, and the Java program is the backend, in which case you would send a GET request from React to the Java program using clients like Axios or the built-in fetch.
The Java program will need to be served on a server or local development server to receive, handle that request, and send a JSON response back to React. You can take a look at creating a RESTful API in Java.

All i get is {} empty object every time i call the function

QUESTION
The Hacker News Firebase API is publicly available, with multiple endpoints allowing you to query for any news item and user. Also, as their Github readme states:
Up to 500 top and new stories are at /v0/topstories (also contains jobs) and /v0/newstories. Best stories are at /v0/beststories.
E.g., hitting https://hacker-news.firebaseio.com/v0/topstories.json?print=pretty returns the ID's of the top 500 stories on HN at that point in time.
My question is, how are these endpoints created and updated on the Firebase end? Firebase Database allows for some rules such as indexOn that optimises queries sorted by ID or upvotes etc..., but the user still needs to make a query requesting the sorted data, using orderBy() for example. I can see nowhere in the Firebase console or docs for creating these endpoints and keeping them updated in the cloud so the endpoint is always returning up-to-date data. How does this work?
ANSWER
Answered 2021-Oct-10 at 20:39It doesn't appear that there is a way to have endpoints like that with content generated on-the-fly by Firebase. It appears that those endpoints are just normal data endpoints, with their data continuously updated by the Hacker News backend to be correct. Firebase isn't the source of truth for HN data anyways: all of the data in the API is updated by a script whenever the underlying data changes in the real database.
QUESTION
I am trying to develop a client for Hacker News using this API, just for learning how Android works, as a personal project. I tried following some tutorials, but I am stuck at a certain point.
I want to retrieve the top N stories' titles, upvotes, etc. This would be done, using this api by:
- Making a request to the api to retrieve the ID's of top posts (500 of them, to be exact)
- For each ID, make a request to the api's posts endpoint to retrieve the details.
It seems that I am stuck on how to create N different network requests for the posts that I want, retrieving them and putting them on a List, then displaying them on my Fragment. I am trying to follow an MVVM pattern, with Repositories. The relevant files are here:

I have a Share Icon that looks like:
I want the first 5 icons to be shown. The 5th icon being the share icon.
I want the rest of the icons to be under share icon & when someone taps or hovers over it (either tap or hover as I don't know what would be best UX in this case), it should open to the right at their usual positions.

Answered 2021-Sep-06 at 18:23Flexbox shouldn't prevent you from using staggerChildren.
To use staggerChildren you add it to the transition property of the parent variants. That means the parent of your list items needs to be a motion component, as do the list items you want to animate.

Answered 2021-Aug-30 at 20:35You might have had an api error where it fails for a certain request. Although as can be seen in this codesandbox example - it's always working https://codesandbox.io/s/crazy-knuth-dbldy?file=/src/App.tsx
As for removing the null value you can append .filter(Boolean) since the null results are useless to you
QUESTION
I am very new to scrapy and am at a point in my project where I am unsure how to proceed. My idea is that I want to scrape the first 2 pages of hackernews and print out all articles / titles with points above 300. Based on my limited knowledge the following code is the best way I could figure out how to get the information I want. My end goal is I need to compare the id with the post id to match them, add the points to the corresponding matches and then filter out points less than 300. I am not sure how I can compare the dictionary values that I have been able to scrape. The code is as follows:

Answered 2021-May-24 at 10:20The posts and scores lists have same length and order.

...ANSWER
Answered 2021-Mar-23 at 17:39That's because the server has been written with the business rule in mind that a Post will always belong to a User. The database has a NOT NULL postedById field on the Link table i.e. a post will always have a user id attached to it. You need to make postedById field nullable in the Link model in the Prisma ORM schema. To fix this, make the following changes on server side code and relaunch the server
In the server folder go to schema.prisma file, and make both fields postedBy and postedById optional/nullable by suffixing them with ?
