How to deal with env variable being string | undefined when clientId is expecting only string?

I'm trying to think of a solution to this... any ideas? So far I'm just doing typeof, and if it is not string then error.

Are you using zod to parse your env file, like we use in create-t3-app?

Samathingamajig•11/20/22, 6:44 AM

if you are, make sure that you import

{ env }

{ env }

instead of going off of

process.env.*

process.env.*

people usually do

as string

as string

nexxel•11/20/22, 6:46 AM

but its better to validate using zod

nexxel•11/20/22, 6:46 AM

we have a very nice system in create-t3-app

amanuelOP•11/20/22, 6:47 AM

No I don't like type assertion here

amanuelOP•11/20/22, 6:47 AM

ok, I'll try using zod

amanuelOP•11/20/22, 6:48 AM

Yeah I already created my own system, t3-stack scaffold wasn't ready yet

@nexxel Any documentation on this zod?

nexxel•11/20/22, 6:48 AM

a simpler way to validate would be like this

import { z } from "zod";

const envSchema = z.object({
  NODE_ENV: z
    .enum(["development", "production", "test"])
    .optional()
    .default("development"),
  DATABASE_URL: z.string().url(),
});

export const env = envSchema.parse(process.env);

import { z } from "zod";

const envSchema = z.object({
  NODE_ENV: z
    .enum(["development", "production", "test"])
    .optional()
    .default("development"),
  DATABASE_URL: z.string().url(),
});

export const env = envSchema.parse(process.env);

now import env from here and everything will autocompleted and typesafe

nexxel•11/20/22, 6:49 AM

and it will throw an error if it doesn't match this schema

amanuelOP•11/20/22, 6:50 AM

this is literally god mode

amanuelOP•11/20/22, 6:50 AM

they should call it "god" instead of "zod"

amanuelOP•11/20/22, 6:50 AM

Thanks for this suggestion

I mean what do you want to do if it's not defined?

Scot•11/20/22, 7:04 AM

You could just throw yourself

Scot•11/20/22, 7:04 AM

Or set it to a default

amanuelOP•11/20/22, 7:15 AM

yeah, that's what I was doing

import { z } from "zod"; const envSchema = z.object({ NODE_ENV: z .enum(["development", "production", "test"]) .optional() .default("development"), DATABASE_URL: z.string().url(), }); export const env = envSchema.parse(process.env);
