Difference between a = useRef(b); and a = useRef(); a.current = b;

Hi, I've been having a problem with an async callback that I would pass to a component where any state variable called within that callback would always be its initial value instead of the current one. The solution that worked ended up being creating a ref to variables I wanted to use within that callback however if the refs were created like this

  const picturesRef = useRef(pictures);
  const filesRef = useRef(files);

  const picturesRef = useRef(pictures);
  const filesRef = useRef(files);

Did anyone try FlexSearch?

I've found this alternative to Algolia which is open source, self-hostable and free, however I've been having some problems with it. Let me paint you my use case. I wanted to do a full text search on a lot of data. In this regard FlexSeach is quire performant. But to persist that data I have to save it in a JSON file, then before searching I import it, and only then FlexSearch splits the data into searchable Indexes, in Algolia those are Documents. The problem is that as far as I've found this full text search engine is not in-memory, which means whenever a request is sent to search (for example if we talk about an API endpoint for searching) it needs to load that JSON first, then index it, then search, and only after that it returns the results....

NextAuth on Apollo Client SSR

Sorry for the bit of a irrelevant question for the discord but is it possible to configure authLink with nextauth on apollo client ssr? My apollo client is basically this repo https://github.com/kellenmace/apollo-client-cache-rehydration-in-next-js/blob/main/lib/apolloClient.ts Plus with this auth link ```const authLink = () => { return setContext(async (_, { headers }) => {...

Node.js API endpoint for PostgreSQL database backup produces empty SQL file

I have an API endpoint in my Node.js application that should perform a backup of my PostgreSQL database and return the result as an SQL file. The API uses the dockerode library to connect to a PostgreSQL container and run the pg_dump command to create the backup. The API sets the response headers to indicate that the result is a download, and pipes the output from the pg_dump command to the response. However, the resulting SQL file is always empty. I have logged the output from the pg_dump command and it appears to be running correctly, but the resulting SQL file is always empty. I have tried several different approaches to writing the data to the response, but have had no luck. Can anyone help me figure out why the SQL file...

Nodemailer SMTP Emails are not being sent in production.

Just to note I'm deploying my t3 application on my own server, I'm not using Vercel. I have confirmed that my env vars are present and good. My problem is that mails via smtp transporter on nodemailer are not being sent in production, while locally they work fine with the same setup. Any help?...
