Walkthrough

A preview mode feature is introduced across the NestJS template through configuration updates, module initialization logic, and request guard modifications. The endpoint startup script is simplified, and Docker configuration adjusted to support the new mode.

Changes

Cohort / File(s)	Summary
Configuration template/nestJs/.env.example, template/nestJs/src/config-schema.ts	Added PREVIEW_MODE configuration option with default value true and accompanying environment variable example.
Startup & Deployment template/nestJs/dockerfile, template/nestJs/endpoint.sh	Updated Dockerfile CMD to use explicit relative path ./endpoint.sh; simplified endpoint.sh to contain only shebang, removing migration and application startup logic.
Application Logic template/nestJs/src/app.module.ts, template/nestJs/src/public/reject.guard.ts	AppModule injects ConfigService and emits preview mode warnings on initialization; RejectRequestGuard now checks PREVIEW_MODE to conditionally bypass request rejection checks.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~12 minutes

• Straightforward boolean flag introduction across multiple files with consistent pattern of reading and conditionally logging/gating behavior
• Minor logic additions (early returns, console warnings) with no complex control flow
• All changes are localized and follow existing patterns

Poem

🐰 A preview mode hops into view,
With flags and configs fresh and new,
Guards check once, then let requests through,
When demo's on, the app says "ooh!"
Warnings whisper: "This isn't true!"

template/nestJs/.env.example (1)

20-21: PREVIEW_MODE sample is clear; optionally reorder to satisfy dotenv-linter

The new comment and PREVIEW_MODE=true sample clearly document the demo-mode toggle. dotenv-linter suggests placing PREVIEW_MODE before REDIS_HOST; if your CI enforces this, consider reordering:

-AUTH_SECRET = 'secret'
-REDIS_SECONDS = 7200
-REDIS_HOST = 'localhost'
-REDIS_PORT = 6379
+AUTH_SECRET = 'secret'
+REDIS_SECONDS = 7200
+# 是否启用演示模式
+PREVIEW_MODE=true
+REDIS_HOST = 'localhost'
+REDIS_PORT = 6379
 ...
-# 是否启用演示模式
-PREVIEW_MODE=true

Otherwise, the current change is fine.

🔇 Additional comments (3)

template/nestJs/dockerfile (1)

27-27: Explicit ./endpoint.sh in CMD is correct

Using an explicit relative path makes the script invocation more reliable inside the container; this change looks good.

template/nestJs/src/config-schema.ts (1)

22-23: Config type and schema extension for PREVIEW_MODE look consistent

Adding PREVIEW_MODE: boolean to Configure and wiring it into CONFIG_SCHEMA with a boolean default of true is consistent and aligns with how it’s used in AppModule and the guard.

Also applies to: 43-44

template/nestJs/src/public/reject.guard.ts (1)

11-13: Guard gating on PREVIEW_MODE matches the intended behavior

Injecting config and returning early when PREVIEW_MODE is disabled cleanly turns off the preview rejection behavior while preserving the existing i18n error path when preview mode is on. This aligns well with the PR objective of toggling demo mode via an env flag.

Also applies to: 16-20, 22-24
