t3 video tutorial typescript error

I am following along with the official t3 stack video tutorial here. At ~24 min, there is a typescript error in TRPC, and Theo restarts the server, which fixes the problem. I am getting the same problem, but restarting the server doesn't fix the problem. Any ideas?

import { z } from "zod";

import { createTRPCRouter, publicProcedure } from "~/server/api/trpc";

export const postsRouter = createTRPCRouter({
  getAll: publicProcedure.query(({ ctx }) => {
    return ctx.prisma.post.findMany();
  }),
});

import { z } from "zod";

import { createTRPCRouter, publicProcedure } from "~/server/api/trpc";

export const postsRouter = createTRPCRouter({
  getAll: publicProcedure.query(({ ctx }) => {
    return ctx.prisma.post.findMany();
  }),
});

This is the error on the ctx.prisma.post.findMany() call

Run prisma generate and restart vs code

Dale•2y ago

npm install isn’t enough?

Diogo•2y ago

What do you mean?

Dale•2y ago

Somewhere in the video, Theo mentioned that you can just run npm install in place of prisma generate to sync up the database sometimes But not really sure why

Diogo•2y ago

Hmmmmm, that's odd, npm install is an npm command, the only thing it does is install , literally, you can't just change what it does. For the contrary, on the package.json under scripts you can make one that when you let's say, run dev, it generates the schema first and then run the build

im still confused when theo use SSG on username, what does he trying to achived and should i use that to on my projects?

@Dale if you have postinstall script in package.json, you can npm install and then it will automatically run what you put in that script 🙂 I do it in my project.

"scripts": {
  "postinstall": "npx prisma generate"
}

"scripts": {
  "postinstall": "npx prisma generate"
}

Maybe that's why he told so But forgot to mention this postinstall or smth
