Hi @desert bluff. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

#

To deploy a Turborepo that contains a NestJS application to Vercel, you can follow these steps. The instructions are based on the provided knowledge sources about deploying Turborepo to Vercel.

Steps to Deploy Turborepo to Vercel

  1. Handle Environment Variables:
    • Ensure you manage environment variables correctly. If your project has environment variables, list them in your turbo.json so Turborepo knows to use different caches for different environments.
    • Example turbo.json configuration:
      {
  "$schema": "<https://turbo.build/schema.json",>
  "pipeline": {
    "build": {
      "dependsOn": ["^build"],
      "env": [
        "SOME_ENV_VAR"
      ],
      "outputs": ["dist/**"]
    },
    "web#build": {
      "dependsOn": ["^build"],
      "env": ["SOME_OTHER_ENV_VAR"],
      "outputs": [".next/**", "!.next/cache/**"]
    }
  },
  "globalEnv": [
    "GITHUB_TOKEN"
  ],
  "globalDependencies": [
    "tsconfig.json"
  ]
}
    • For more details, refer to the Handling environment variables (https://vercel.com/docs/monorepos/turborepo#handling-environment-variables) section.
#

  1. Import Your Turborepo to Vercel:

    • If you haven't already connected your monorepo to Turborepo, follow the quickstart (https://turbo.build/repo/docs) on the Turborepo docs.
    • Create a new project on the Vercel dashboard and import your Turborepo project. Vercel will handle configuring your monorepo, including setting build commands, output directory, root directory, and ignored build steps.
    • Example configuration table:
      Field Command
      Build Command turbo run build (requires version >=1.8)
      Output Directory Framework default
      Install Command Automatically detected by Vercel
      Root Directory App location in repository (e.g., apps/web)
      Ignored Build Step npx turbo-ignore --fallback=HEAD^1

  2. Using Global turbo:

    • Turborepo is available globally when deploying on Vercel, so you do not need to add turbo as a dependency in your application.
    • Your build command can be as straightforward as:
      turbo build
    • The appropriate filter will be automatically inferred based on the configured root directory. To override this behavior and use a specific version of Turborepo, install the desired version of turbo in your project.
    • For more details, refer to the Using global turbo (https://vercel.com/docs/monorepos/turborepo#using-global-turbo) section.
#
  1. Enable Remote Caching:
    • When you run turbo commands during a Vercel Build, Remote Caching will be automatically enabled. No additional configuration is required.
    • For more information, refer to the Remote Caching (https://vercel.com/docs/monorepos/remote-caching) section.

By following these steps, you should be able to deploy your Turborepo containing a NestJS application to Vercel successfully. For more detailed information, you can refer to the [Vercel documentation on Turb

@sharp birch but when build it not provide api just 404 i use nestjs not nextjs

Let me check the knowledge base for you. One moment! :books:

#

If your API routes are returning a 404 error when deploying your Turborepo with a NestJS application to Vercel, there are a few things you can check and configure to resolve this issue.

Steps to Resolve 404 Errors for API Routes

  1. Check Your API Routes Configuration:
    Ensure that your API routes are correctly configured in your NestJS application. Verify that the routes are properly defined and that the NestJS application is correctly set up to handle these routes.

  2. Custom 404 API Response:
    If you need a custom 404 response for your API, you can create a Serverless Function that sets the status code to 404 and responds with a JSON message. Here’s an example:

    // /api/404.js
module.exports = (req, res) => {
  res.status(404).json({ message: 'Not Found' });
};

    Then, add an entry at the bottom of rewrites in vercel.json to ensure that the 404 Serverless Function will execute if nothing else matches in the /api directory:

    {
  "rewrites": [
    { "source": "/api/(.*)", "destination": "/api/404.js" }
  ]
}

    This configuration ensures that any unmatched API requests will return a JSON 404 response. For more details, refer to the Vercel Guide on Custom 404 API Response (https://vercel.com/guides/custom-404-page#what-if-i-need-a-custom-404-api-response).

  3. Middleware Configuration:
    If you are using middleware in your NestJS application, ensure that it is correctly configured and not causing the 404 errors. Middleware can sometimes interfere with route handling if not properly set up.

#

  1. Debugging in Development:
    If the issue persists, try running the build locally and debugging the application. Sometimes, errors that do not appear in the console during development can surface during the build process. Running next build locally can help identify such issues.

    npm run build
npm run start

  2. Check for Errors in Middleware:
    If you have a middleware.ts file, ensure it is not causing the 404 errors. Middleware can sometimes inadvertently block routes or cause unexpected behavior.

    // Example middleware.ts
import { NextResponse } from 'next/server';

export function middleware(req) {
  // Your middleware logic here
  return NextResponse.next();
}

By following these steps, you should be able to identify and resolve the 404 errors for your API routes when deploying your Turborepo with a NestJS application to Vercel. If you need further assistance, you can refer to the Vercel documentation (https://vercel.com/docs) for more detailed guidance.

@sharp birch why vercel build in local gen function api but when deploy not gen

sharp birchBOT
#

Let me check the knowledge base for you. One moment! :books:

#

If your Vercel build works locally and generates the function API but does not do so when deployed, there are a few potential issues to investigate. Here are some steps to troubleshoot and resolve this issue:

Steps to Troubleshoot and Resolve

  1. Check Environment Variables:
    Ensure that all necessary environment variables are set in the Vercel dashboard. Environment variables that are available locally might not be set in the Vercel deployment environment.

    • Go to your Vercel project dashboard.
    • Navigate to the "Settings" tab.
    • Under "Environment Variables," add any variables that your build process depends on.

  2. Ensure Correct Build Command:
    Verify that the build command specified in Vercel is the same as the one you use locally. This ensures that the build process is consistent across environments.

    • In your vercel.json:
      {
  "version": 2,
  "builds": [
    {
      "src": "apps/api/dist/main.js",
      "use": "@vercel/node"
    }
  ],
  "routes": [
    {
      "src": "/api/(.*)",
      "dest": "apps/api/dist/main.js"
    }
  ]
}

  3. Check for Native Dependencies:
    If your project uses native dependencies, ensure they are correctly handled in the Vercel environment. Native dependencies might work locally but fail in the Vercel serverless environment.

    • Consider using pure JavaScript alternatives if possible.
    • For example, if you are using bcrypt, switch to bcryptjs.

  4. Review Build Logs:
    Check the build logs in the Vercel dashboard to identify any errors or warnings that might indicate why the function API is not being generated.

    • Go to your Vercel project dashboard.
    • Navigate to the "Deployments" tab.
    • Click on the latest deployment to view the build logs.
#

  1. Ensure Correct Output Directory:
    Make sure that the output directory specified in your build configuration matches the one expected by Vercel.

    • In your nest-cli.json:

      {
  "collection": "@nestjs/schematics",
  "sourceRoot": "src",
  "compilerOptions": {
    "webpack": true,
    "tsConfigPath": "tsconfig.build.json"
  }
}

    • In your tsconfig.build.json:

      {
  "extends": "./tsconfig.json",
  "compilerOptions": {
    "outDir": "./dist",
    "declaration": true,
    "declarationMap": true,
    "sourceMap": true
  },
  "include": ["src/**/*"],
  "exclude": ["node_modules", "test", "dist", "**/*spec.ts"]
}

  2. Check for File System Access:
    Ensure that your build process does not rely on file system access that is not available in the Vercel serverless environment.

    • Serverless functions have limited file system access and are stateless.
    • Use external storage solutions if persistent storage is required.

By following these steps, you should be able to identify and resolve the issue causing the function API to not be generated when deploying to Vercel. For more detailed information, you can refer to the Vercel documentation (https://vercel.com/docs) and the Turborepo documentation (https://turbo.build/repo/docs).
