chore(deps): bump @nestjs/config from 4.0.4 to 12.0.0

[dependabot]

Bumps @nestjs/config from 4.0.4 to 12.0.0.

Release notes

Sourced from @​nestjs/config's releases.

12.0.0

What's Changed

@nestjs/config is now a native ES module, environment validation is built on Standard Schema instead of Joi-specific code, and the major version is aligned with the Nest 12 release line (there is no 5.x — 4.0.4 goes straight to 12.0.0).

ESM migration

The package is published as pure ESM ("type": "module", compiled with NodeNext) behind a proper exports map. The legacy root index.js / index.d.ts shims are gone, and deep imports into build internals are no longer resolvable — import from the package root.

// ✅
import { ConfigModule, ConfigService } from '@nestjs/config';
// ❌ no longer resolvable
import { ConfigService } from '@​nestjs/config/dist/config.service';

require(esm) — CommonJS still works

You do not need to convert your app to ESM. Thanks to Node's require(esm) support (Node 20.19+ / 22.12+), a CommonJS app can keep using require('@nestjs/config') unchanged.

Validation is now Standard Schema based

validationSchema accepts any schema implementing the Standard Schema spec — Zod (v3, v4, v4-mini), Valibot, ArkType, Joi 18+, and anything else that adopts it. There is no longer any Joi-specific code path in the module, and Joi is no longer implied as the validation library.

ConfigModule.forRoot({
  validationSchema: z.object({
    PORT: z.coerce.number().default(3000),
    DATABASE_NAME: z.string(),
  }),
});

Joi keeps working — it implements Standard Schema as of v18 — and the historical abortEarly: false / allowUnknown: true defaults are still applied automatically for Joi schemas, so existing Joi setups behave as before.

Breaking: validationOptions shape

Options are now the Standard Schema Options object, and library-specific settings move under libraryOptions:

// Before (4.x)
validationOptions: { allowUnknown: false, abortEarly: true }
// Now (12.x)
validationOptions: { libraryOptions: { allowUnknown: false, abortEarly: true } }

The generic parameter changed accordingly: ConfigModuleOptions<ValidationOptions extends StandardSchemaV1.Options>, and validationSchema is typed as StandardSchemaV1 rather than any — a schema that does not implement the spec is now a compile-time error instead of a runtime one.
