Type safe environment variables

Is it possible to get type safety for environment variables, so that my app only builds if I have added all required environment variables to convex, similar to T3 Env for regular next.js/vercel deployments?

Using Neverthrow with convex

I am trying to add neverthrow to my convex functions to get type safety, but when i add ok({hello: "world"}) in a mutation, i get an error complaining about the fact that convex does not accept the type. Is there any way to add neverthrow to my mutations? And if not: What is the suggested way for getting type safe errors in convex?

When to use clerk over convex auth

It seems to me that convex auth is a really powerful auth library, it is nice to keep everything in one codebase, it does not seem complex to set up and it is cheaper than clerk if you want sessions that are longer than 7 days. What are the reasons for chosing clerk over convex auth?

Type safety for nested objects on patch

Is there any way to get type safety on patch operations in convex? schema:

import { defineSchema, defineTable } from "convex/server";
import { v } from "convex/values";

const reactiveText = v.object({
  stateId: v.string(),
  text: v.string(),
});

export default defineSchema({
  myData: defineTable({
    text1: reactiveText,
    text2: reactiveText,
  }),
});

import { defineSchema, defineTable } from "convex/server";
import { v } from "convex/values";

const reactiveText = v.object({
  stateId: v.string(),
  text: v.string(),
});

export default defineSchema({
  myData: defineTable({
    text1: reactiveText,
    text2: reactiveText,
  }),
});

myfunction

import { v } from "convex/values";
import { query, mutation, action } from "./_generated/server";
import { api } from "./_generated/api";

export const update = mutation({
  args: {
    text: v.string(),
    id: v.id("myData"),
    stateId: v.string(),
    field: v.union(v.literal("text1"), v.literal("text2")),
  },
  handler: async (ctx, args) => {
    await ctx.db.patch(args.id, {
      [args.field]: { text: args.text },
      // should have been
      [args.field]: { text: args.text, stateId: args.stateId },
    });
  },
});

import { v } from "convex/values";
import { query, mutation, action } from "./_generated/server";
import { api } from "./_generated/api";

export const update = mutation({
  args: {
    text: v.string(),
    id: v.id("myData"),
    stateId: v.string(),
    field: v.union(v.literal("text1"), v.literal("text2")),
  },
  handler: async (ctx, args) => {
    await ctx.db.patch(args.id, {
      [args.field]: { text: args.text },
      // should have been
      [args.field]: { text: args.text, stateId: args.stateId },
    });
  },
});

This does not show any type errors

Not using middleware in nextjs

I don't want to move the user to different routes based on if they are logged in or now. Are there any reasons for me to still keep the middleware? I am using convex auth

Allowing user to update value streamed from LLM

I am making a chat-like app with ChatGPT using the component https://www.convex.dev/components/persistent-text-streaming. I want the user to be able to edit all the responses after they finish streaming. How can I achieve that? Is it possible to bind a textarea to a convex mutation and have it real time sync?
