app.use(express.json()); //i use this as a middleware for nodejs
This is the error i got: Router.use() requires a middleware function but got a string

I have code
res.cookie("user", "token");
I can't get cookies on a post request to the API. But if you test the API through Postman, then he can easily get cookies.
What could be the problem? I didn't specify which header or what?

Discord.js code doesn't work sending embed messages
Code embed :
Error code :
This is happening because you are using client#channels#cache#get which is not a valid function since client is not defined in the code block.
You need to use member.guild.channels.cache.get('<id goes here>').send(embed);

In discord.js, how can I check that a user inside a voice channel is deafened? I read the docs and I couldn't find anything related to this
If you look under GuildMember there is a .deaf property as well as .selfDeaf and .serverDeaf. This will return a boolean value.
Resource: https://discord.js.org/#/docs/main/stable/class/GuildMember?scrollTo=deaf
So for example:
message.member.deaf
message.member.selfDeaf
message.member.serverDeaf

I have no idea how to render the time of a post being posted on my blog. I am using express as backend and template engine (express-edge).
you could use https://www.npmjs.com/package/i18n-js if you need to translate a date into anothers langages
you could also just use this
