Update Feed in parser service to talk to Supabase instead of Redis

[TueeNguyen]

In #1907 #3355, we talked about removing feed-related code in Posts.

• Change setInvalidFeed function to use Supabase

  telescope/src/api/parser/src/utils/storage.js

  Lines 111 to 115 in d56306a

  	setInvalidFeed: (id, reason) => {
  	const key = createInvalidFeedKey(id);
  	const sevenDaysInSeconds = 60 * 60 * 24 * 7; // Expire after 7 days
  	return redis.set(key, reason, 'EX', sevenDaysInSeconds);
  	},

• telescope/src/api/parser/src/utils/storage.js

  Lines 137 to 139 in d56306a

  	setFlaggedFeed: (id) => redis.smove(feedsKey, flaggedFeedsKey, id),
  	unsetFlaggedFeed: (id) => redis.smove(flaggedFeedsKey, feedsKey, id),

There's also this:

• The parser service does not need to updateFeeds anymore. Refer to:
  

  telescope/src/api/parser/src/parser.js

  Line 48 in d56306a

  const currentFeed = await updateFeed(feed);

  
  

  telescope/src/api/parser/src/parser.js

  Lines 12 to 28 in d56306a

  	const updateFeed = async (feedData) => {
  	let currentFeed;
  	// If we have an existing feed in the database for this URL, prefer that,
  	// since it might have updated cache info (e.g., etag).
  	const existingFeed = await Feed.byUrl(feedData.url);
  	if (existingFeed) {
  	// We have a version of this feed in the database already, prefer that
  	currentFeed = existingFeed;
  	} else {
  	// First time we're seeing this feed, add it to the database
  	const id = await Feed.create(feedData);
  	currentFeed = await Feed.byId(id);
  	}
  	return currentFeed;
  	};

I'm working on this issue to make parser save flagged feeds to supabase (simply change flagged of feed to true/false). I encountered this piece of code

telescope/src/api/parser/src/utils/storage.js

Line 53 in 47fd69e

if (await redis.sismember(flaggedFeedsKey, feed.id)) return;

I will also need to change this line if I'm removing all the redis flagging feed code, something like this

if (await isFlaggedFeed(feed.id)) // isFlaggedFeed() is function that uses supabase
  return; 

Therefore, the test won't pass and there's no mock cilent for supabase at the moment. I'm not sure what's the next step is

Mock the isFlaggedFeed() function to return Promise.resolve(true) or Promise.resolve(false) as you require in your tests.

I'll try, thanks

After looking at the function

telescope/src/api/parser/src/parser.js

Lines 12 to 28 in 9ec0cf0

	const updateFeed = async (feedData) => {
	let currentFeed;
	// If we have an existing feed in the database for this URL, prefer that,
	// since it might have updated cache info (e.g., etag).
	const existingFeed = await Feed.byUrl(feedData.url);
	if (existingFeed) {
	// We have a version of this feed in the database already, prefer that
	currentFeed = existingFeed;
	} else {
	// First time we're seeing this feed, add it to the database
	const id = await Feed.create(feedData);
	currentFeed = await Feed.byId(id);
	}
	return currentFeed;
	};

I believe we can keep it as it looks for feed object in Redis not in Supabase.
