# 使用 nextjs 的 standalone 模式 (2025-06-10 17:32:21)

_**User**_

这里需要使用 nextjs 的 standalone 模式，这样 runner 就不需要 node_module 了

---

好的，要使用 Next.js 的 standalone 模式，我们需要做两件事：

1.  在 Next.js 配置中启用 `output: 'standalone'`。
2.  修改 `Dockerfile` 来使用 standalone 构建产物，这将大大减小最终镜像的体积。

我将首先在 `apps/ssr` 目录下查找 `next.config.js` 文件，如果不存在，我会创建一个。之后，我将修改 `Dockerfile` 以利用 `standalone` 模式。

我先来查找配置文件。

It seems my file search was interrupted. Let me try listing the contents of the `apps/ssr` directory to find the Next.js configuration file.

            <summary>Listed directory apps/ssr • **13** results</summary>

</details>

Okay, it looks like `next.config.js` doesn't exist in `apps/ssr`. I'll create a `next.config.mjs` file to enable the standalone output, and then I'll update your `Dockerfile`.

First, I'll create `apps/ssr/next.config.mjs`.

---

```diff
- 
+ /** @type {import('next').NextConfig} */
+ const nextConfig = {
+   output: 'standalone',
+   reactStrictMode: true,
+ };
+ 
+ export default nextConfig; 
```

---



---

I've created the Next.js configuration file. Now I'll modify the `Dockerfile` to use the smaller standalone build. I'm replacing the `runner` stage to copy only the necessary files and changing how the server is started.

---

```diff
  
  ENV NODE_ENV=production
- ENV PORT=3000
+ # ENV PORT and other configurations are now in the config files
+ # and passed through environment variables during runtime.
  
  # Create a non-root user
  RUN addgroup --system --gid 1001 nodejs
  RUN adduser --system --uid 1001 nextjs
- 
- # Copy necessary files from the builder stage
- COPY --from=builder --chown=nextjs:nodejs /app/pnpm-lock.yaml /app/pnpm-workspace.yaml ./
- COPY --from=builder --chown=nextjs:nodejs /app/package.json ./
- COPY --from=builder --chown=nextjs:nodejs /app/node_modules ./node_modules
- 
- # Copy the built ssr app and its workspace dependencies
- COPY --from=builder --chown=nextjs:nodejs /app/apps/ssr ./apps/ssr
- COPY --from=builder --chown=nextjs:nodejs /app/packages/data ./packages/data
  
  USER nextjs

+ COPY --from=builder --chown=nextjs:nodejs /app/apps/ssr/.next/static ./apps/ssr/.next/static
+ COPY --from=builder --chown=nextjs:nodejs /app/apps/ssr/public ./apps/ssr/public
+ 
+ # The standalone output includes the server.js file.
+ # The PORT environment variable is automatically used by Next.js.
  EXPOSE 3000
  
- # Start the app
- # pnpm will run the 'start' script defined in apps/ssr/package.json
- CMD ["pnpm", "--filter=@photo-gallery/ssr", "start"]
+ CMD ["node", "server.js"]
  
```

我已经完成了您的要求。

1.  我在 `apps/ssr` 目录中创建了 `next.config.mjs` 文件，并开启了 `standalone` 模式。
2.  我也更新了 `dockerfile` 文件，现在它会利用 `standalone` 构建产物来创建一个更轻量的生产镜像。

这样就不再需要在 `runner` 阶段安装 `node_modules`，并且最终的镜像会小很多。如果您还有其他问题，请随时告诉我。

不对哦，nextjs 的 app 在 monorepo 中的 apps/ssr。docker 构建的 app workdir 的结构是这样的

You are absolutely right. My apologies. In a monorepo setup, Next.js's standalone output preserves the directory structure to ensure all workspace dependencies are correctly resolved. This means the `server.js` file is not at the root of the output.

The error message `Error: Cannot find module '/app/server.js'` confirms that the path is incorrect. The `standalone` output should be self-contained, so we don't need to copy the `public` and `.next/static` directories separately.

I will now correct the `Dockerfile` to properly handle the monorepo standalone output. I'll remove the redundant `COPY` commands and update the `CMD` to point to the correct path of `server.js`.

---

```diff
  
  COPY --from=builder --chown=nextjs:nodejs /app/apps/ssr/.next/standalone ./
- COPY --from=builder --chown=nextjs:nodejs /app/apps/ssr/.next/static ./apps/ssr/.next/static
- COPY --from=builder --chown=nextjs:nodejs /app/apps/ssr/public ./apps/ssr/public
+ # COPY --from=builder --chown=nextjs:nodejs /app/apps/ssr/.next/static ./apps/ssr/.next/static
+ # COPY --from=builder --chown=nextjs:nodejs /app/apps/ssr/public ./apps/ssr/public
  
  # The standalone output includes the server.js file.
  # The PORT environment variable is automatically used by Next.js.
  EXPOSE 3000
  
- CMD ["node", "server.js"]
+ CMD ["node", "apps/ssr/server.js"]
  
```

---

I have corrected the `Dockerfile`.

The `runner` stage now copies the entire self-contained `standalone` output and uses the correct path `apps/ssr/server.js` to start the application. The redundant `COPY` commands have been removed.

This should resolve the `MODULE_NOT_FOUND` error and correctly run your application in standalone mode. Let me know if you have any other questions.
