Turborepo + github action example

Help
1

I’m aware of examples/ci-cd/github-actions at main · vercel/examples · GitHub

but I cannot find a working example of a turborepo/monorepo deploying a nextjs application

I’ve failed for over 48 hours now attempting to wrestle with the vercel cli to get this deployed - a maintained example by the vercel team would be appreciated…

here is my very simple github action…

name: Beta Deployment

on:
  push:
    branches: ["canary"]

env:
  TURBO_TOKEN: ${{ secrets.TURBO_TOKEN }}
  TURBO_TEAM: ${{ secrets.TURBO_TEAM }}
  VERCEL_ORG_ID: ${{ secrets.VERCEL_ORG_ID }}
  VERCEL_PROJECT_ID: ${{ secrets.VERCEL_PROJECT_ID }}

jobs:
  deploy:
    runs-on: ubuntu-latest
    timeout-minutes: 20
    steps:
      - uses: actions/checkout@v4
        with:
          fetch-depth: 2

      - uses: pnpm/action-setup@v4
        with:
          version: 10.7.1
          run_install: false

      - uses: actions/setup-node@v4
        with:
          cache: "pnpm"
          node-version: 22

      # Add Turborepo cache
      - name: Cache Turborepo
        uses: actions/cache@v4
        with:
          path: .turbo
          key: ${{ runner.os }}-turbo-${{ github.sha }}
          restore-keys: |
            ${{ runner.os }}-turbo-

      - name: Install dependencies
        run: pnpm install

      - name: Install Vercel CLI
        run: pnpm add -g vercel@latest

      - name: Pull Vercel Environment Information
        run: pnpm --filter="@app/www" exec vercel pull --yes --environment=production --token=${{ secrets.VERCEL_TOKEN }}

      - name: Build Project Artifacts
        run: pnpm --filter="@app/www" exec vercel build --prod --token=${{ secrets.VERCEL_TOKEN }}

      - name: Deploy Project Artifacts to Vercel
        run: pnpm --filter="@app/www" exec vercel deploy --prod --token=${{ secrets.VERCEL_TOKEN }}

here’s where it fails

Run pnpm --filter="@***/www" exec vercel build --prod --token=***
  pnpm --filter="@***/www" exec vercel build --prod --token=***
  shell: /usr/bin/bash -e {0}
  env:

    VERCEL_PROJECT_ID: ***
    OPENAI_API_KEY: ***
    PNPM_HOME: /home/runner/setup-pnpm/node_modules/.bin

/home/runner/work/monorepo/monorepo/apps/www:

I know the vercel cli is working, because the step before is successful

Run pnpm --filter="@***/www" exec vercel pull --yes --environment=production --token=***

I do have ENABLE_EXPERIMENTAL_COREPACK enabled, but this is only to pin the pnpm version, which is the installed version in this workflow…

please advise…

for reference:

  • I’ve also tried to build the app locally within the action (it is successful), and deploying via the `–prebuilt`` option but what ends up getting deployed is a blank app.
  • I’ve also tried building the app and then triggered deploy with vercel hoping that turborepo will have cached that build, that also fails.

I understand the desire to keep builds on vercel, but this is incredibly frustrating that there’s not supported examples for what I would imagine would be a fairly common setup turborepo+nextjs+vercel-deployment
