Using Turborepo with CircleCI

The following example shows how to use Turborepo with CircleCI.

For a given root package.json:

{
  "name": "my-turborepo",
  "scripts": {
    "build": "turbo run build",
    "test": "turbo run test"
  },
  "devDependencies": {
    "turbo": "1.2.5"
  }
}

And a turbo.json:

{
  "$schema": "https://turbo.build/schema.json",
  "pipeline": {
    "build": {
      "dependsOn": ["^build"],
      "outputs": []
    },
    "test": {
      "dependsOn": ["^build"],
      "outputs": []
    },
  }
}

Create a file called .circleci/config.yml in your repository with the following contents:

version: 2.1
orbs:
  node: circleci/node@5.0.2
workflows:
  test:
    jobs:
      - test
jobs:
  test:
    docker:
      - image: cimg/node:lts
    steps:
      - checkout
      - node/install-packages
      - run:
        command: npm run build
      - run:
        command: npm run test

Remote Caching

To use Remote Caching with CircleCI, add the following environment variables to your CircleCI project to make them available to your turbo commands.

  • TURBO_TOKEN - The Bearer token to access the Remote Cache
  • TURBO_TEAM - The account to which the monorepo belongs

To use Vercel Remote Caching, you can get the value of these variables in a few steps:

  1. Create a Scoped Access Token to your account in the Vercel Dashboard

Vercel Access Tokens Vercel Access Tokens

Copy the value to a safe place. You'll need it in a moment.

  1. Go to your CircleCI project settings and click on the Environment Variables tab. Create a new secret called TURBO_TOKEN and enter the value of your Scoped Access Token.

CircleCI Environment Variables CircleCI Create Environment Variables

  1. Make a second secret called TURBO_TEAM and enter the value of your team's Vercel URL without the vercel.com/. Your Team URL can be found inside your team's general project settings from the dashboard.

    If you're using a Hobby Plan, you can use your username. Your username can be found in your Vercel Personal Account Settings

  1. CircleCI automatically loads environment variables stored in project settings into the CI environment. No modifications are necessary for the CI file.
