09/05/2019, 8:28 PM@tmoney Thanks for your reply! My setup basically has no frontend. I have only a backend application with a scheduler which performs an action to retrieve data for my prisma database. Now I want to execute an alert message (in my nodejs application) when data is being added -- So I think websockets are not the right use case for this

Copy code
const createdUserIterator = await db.$subscribe
.user({
mutation_in: ['CREATED'],
node: {
email_contains: `<mailto:alice@prisma.io|alice@prisma.io>`,
},
})
.node()t

09/05/2019, 8:38 PMokay alright then I need to think about something else. Right now I have a setInterval() which checks for new items every 5 minutes and inserts the items into the database. As the createItem function always returns what you added, even if it's already in the database, I now need to figure out how to check if there has been a new item added to the database. Do you have any idea for that? 😄
