Fetch events with subscription and check relay

[MSghais]

Description

We when fetchEvent with ndk.fetchEvents, if a relay are not unreachable, it's throw an error and return an empty array.
Create a robust subscription/fetch that's return datas of the reachable relay Nostr, check the nostr-dev-kit

Do this hooks in: packages/afk_nostr_sdk.

Try different more robust implementations that's not throw an error if one of the relay have an issue:

• ndk.subscribe(), check if relay

• a hooks that's check if relay is ok before fetch

• Try to add this Relay with error in the relay.ts:

  'wss://relay.nostr.band',
  'wss://purplepag.es',
  'wss://relay.snort.social',
  'wss://nos.lol'

• Create a robust hooks with ndk.subscribe, that fetchEvent and not throw error if relay is unreachable

• Create a store data with zutsand for Notes subscription, so we can render it like a webhook in the UI

Few relays to test, check if one is not working also try with RELAYS undefined or incorrect:

Hi, I'm Wilfrid Okorie, a Frontend Web Developer and I'd like to take this issue

[Emmanex01]

Can I try solving this issue?
I'm a software developer, I have experience building with Typescript, JavaScript, Cairo. I have built and contributed to projects both on ODHack and off ODHack. If given the opportunity I would deliver as soon as possible.

Hello i was hoping if i can give this a shot again, i understand the task and i would like to work on it carefully. ETA 12 hours

I’m interested in this issue, I can contribute by creating a robust hook in packages/afk_nostr_sdk for handling ndk.subscribe() and fetchEvents. My approach will focus on improving error tolerance, ensuring data retrieval from reachable relays, and avoiding disruptions when encountering unreachable or misconfigured relays.

To achieve this, I’ll:

Check relay status before fetching data.
Implement fallback mechanisms to handle errors gracefully.
Integrate zustand for state management, enabling seamless data rendering like a webhook in the UI.
Test extensively with the provided relays, including scenarios with undefined or incorrect RELAYS.
ETA: 24 to 36 hours tops

Hello @MSghais,

I'm interested in contributing to this issue.

As a developer experienced with Nostr development and state management, I can help create a robust solution for handling relay connectivity and event fetching.

What I would do in this task involves:

Implementing a resilient hooks in packages/afk_nostr_sdk that handles potential relay connection issues
Creating a Zustand store for managing Notes subscriptions
Developing error-handling mechanisms for ndk.fetchEvents() and ndk.subscribe()
Testing the implementation with multiple relays, including edge cases like unreachable or undefined relays

I would be able to complete this within 2 days,

My approach will focus on:

• Graceful error handling
• Partial data retrieval from available relays
• Efficient state management
• Comprehensive testing of different relay scenarios`
