Improve drizzle-orm SQLite default template

[hyunbinseo]

As of Svelte CLI v0.6.26

• db:generate is not included in the scripts:

  "db:push": "drizzle-kit push",
  "db:migrate": "drizzle-kit migrate",
  "db:studio": "drizzle-kit studio"
  "db:migrate": "drizzle-kit migrate", // missing

• Unused variable is included in the schema.ts file:

// 'text' is declared but its value is never read.ts(6133)
import { sqliteTable, text, integer } from 'drizzle-orm/sqlite-core';

export const user = sqliteTable('user', {
  id: integer('id').primaryKey(),
  age: integer('age')
});

• Line-breaks are missing in the drizzle.config.ts file:

import { defineConfig } from 'drizzle-kit';
if (!process.env.DATABASE_URL) throw new Error('DATABASE_URL is not set');

• loadEnvFile should probably be called in the drizzle.config.ts file:

import { defineConfig } from 'drizzle-kit';
import { loadEnvFile } from 'node:process';

loadEnvFile();

if (!process.env.DATABASE_URL) throw new Error('DATABASE_URL is not set');

• @types/node should probably be installed out-of-the box.

import { defineConfig } from 'drizzle-kit';

// Cannot find name 'process'. Do you need to install type definitions for node? Try `npm i --save-dev @types/node`.ts(2580)
if (!process.env.DATABASE_URL) throw new Error('DATABASE_URL is not set');

• Line-breaks are missing in the src\lib\server\db\index.ts file:

import { drizzle } from 'drizzle-orm/libsql';
import { createClient } from '@libsql/client';
import * as schema from './schema';
import { env } from '$env/dynamic/private';
if (!env.DATABASE_URL) throw new Error('DATABASE_URL is not set');
const client = createClient({ url: env.DATABASE_URL });

Are there reasons behind these decisions? If not, I would love to create a PR.

1. db:generate is not included in the scripts:

You are right. Either we should remove migrate or add generate, as per the docs.

2. Unused variable is included in the schema.ts file:

You are right!

3. Line-breaks are missing in the drizzle.config.ts file:

Does not only apply to the drizzle add-on, but to a bunch of different ones. Should be resolved after #380 is merged. Feel free to try that PR via pnpm dlx https://pkg.pr.new/sveltejs/cli/sv@380 and provide feedback there. This should also resolve all tabs vs space inconsistencies.

4. loadEnvFile should probably be called in the drizzle.config.ts file:

I guess that makes sense technically, but have you already encountered such a use-case? Using vitest in example does not make this command necessary. I assume this would only be a problem if executing node directly? Also I was unable to find any reference to this method in the drizzle docs as a recommended step or something: https://orm.drizzle.team/docs/get-started/sqlite-new

5. @types/node should probably be installed out-of-the box.

I might be asking strange questions today, but I'm currently unable to reproduce this. I used the minimal template with the js option, and even pnpm check is not reporting anything for me.

6. Line-breaks are missing in the src\lib\server\db\index.ts file:

Same as above.

Would appreciate your PR, but I would suggest to wait until #380 is merged to avoid merge conflicts.

4. loadEnvFile() is needed for these commands:

• drizzle-kit generate
• drizzle-kit migrate

It works in Vitest because it's basically Vite which imports env files accordingly.

5. It happened in my Windows dev environment, which I can revisit on Monday. I cannot reproduce it in macOS.

// var process: NodeJS.Process - works in macOS out-of-the-box
if (!process.env.DATABASE_URL) throw new Error('DATABASE_URL is not set');

Oh yeah, able to reproduce 4. now 👍

@types/node issue happens in Windows environment only.

Property 'dirname' does not exist on type 'ImportMeta'. ts(2339)

For some reason, installing @types/node once and then uninstalling it fixes the problem.

(property) ImportMeta.dirname: string

[manuel3108]

Ok, then let's add @types/node. I'm wondering if this only happened to you once you installed drizzle or was the default template already throwing such errors? Im asking this because im unsure if the @ŧypes/node should be part of the default templates, or only added if drizzle is detected.
We could have a look at how different frameworks are handling this.

Now that #380 is merged, issues 3. and 6. should not be happening anymore.

[hyunbinseo]

1. I've converted the issue body to a checklist and checked 3 and 6.
2. I can create a separate @types/node issue and see if people are experiencing it as well.

I don't have multiple Windows environments to test from, and I can always install @types/node on my own when a problem occurs.

[manuel3108]

As for the @types/node issue, looks like you are not the only one. Maybe it's related in to the library template. Let's investigate this in #509
