Turborepo 2.5

<Date>Thursday, April 3rd, 2025</Date>

<Authors authors={["nicholasyang", "anthonyshew", "chrisolszewski"]} />

Turborepo 2.5 includes a number of improvements to enhance your repository:

Upgrade today by running npx @turbo/codemod migrate or get started with npx create-turbo@latest.

Sidecar tasks

In some cases, you want to ensure two long-running tasks are always running at the same time. For example, you may have a web application that makes requests to another application in your monorepo. Running the web application by itself may not be useful, since the backend API application won’t be available to serve its requests.

You may have tried to use dependsOn to create this relationship - but quickly discovered that depending on a long-running task isn’t allowed. A long-running task never exits, so the dependent task would never run. This meant you’d have to carefully craft a --filter to ensure those resources are available—and make sure everyone in the repo knows to use it.

Instead, we’re introducing the with key so you can guarantee that a dependent long-running task always runs with the long-running tasks that it depends on at runtime.

json
{
  "tasks": {
    "dev": {
      "with": ["api#start"],
      "persistent": true,
      "cache": false
    }
  }
}

Using this Package Configuration, anytime that the web application’s dev task is started, the api's start task will also run using the package#task microsyntax.

Visit the documentation to learn more.

Improved control for --continue behavior

By default, Turborepo stops running tasks when it encounters a task that has failed. You can alter this behavior using the --continue flag, instructing Turborepo to continue running tasks, even when one or more tasks have failed.

While the --continue flag is useful, there are times when running tasks whose dependencies have failed will only result in more failures. For these situations, we’ve added a new value to the --continue flag in this release: --continue=dependencies-successful.

bash
turbo run test --continue=dependencies-successful

When using this value, all dependencies for a task must be successful for the dependent task to run.

Learn more in the documentation.

The Turborepo core team would like to thank @jenseng for contributing this feature.

Add comments to your Turborepo configuration files

You can now use JSONC (turbo.jsonc) for your configuration files, allowing you to add useful comments to your configuration.

json
{
  "tasks": {
    "test": {
      // Our tests need their dependencies to be built first
      "dependsOn": ["^build"]
    }
  }
}

Pruned monorepos for Bun repositories

turbo prune creates a partial monorepo for a target package, and is especially useful for creating lightweight Docker images from monorepos. This command has been available for pnpm, npm, and Yarn repositories in previous versions of Turborepo.

In this release, turbo prune is now available for Bun v1.2+, which has introduced a text-based lockfile that we can now read and analyze.

bash
turbo prune web

Reference your workspace root with the $TURBO_ROOT$ microsyntax

In some situations, you’re forced to break out of package boundaries in a monorepo. This could be due to a number of constraints, like tooling that doesn’t conform to modern package manager workspaces or incremental migration workflows that take you out of ideal conditions.

In the past, you’d need to write paths in turbo.json that traverse to the workspace root, since globs are anchored to the root of packages:

json
{
  "tasks": {
    "build": {
      "inputs": ["../../important-file.txt"]
    }
  }
}

While this pattern does work, it can lead to inconsistencies in some cases:

  • Some packages may need ../ while others need ../../
  • A developer could potentially move a package to a different location so that the path isn’t correct

Instead, you can now use the $TURBO_ROOT$ microsyntax:

json
{
  "tasks": {
    "build": {
      "inputs": ["$TURBO_ROOT$/important-file.txt"]
    }
  }
}

Now, this file glob is guaranteed to always start at the root of your workspace.

OpenAPI specification viewer for self-hosting

Turborepo is proudly open-source with a public specification for its Remote Caching protocol. While Vercel Remote Cache is a free-to-use managed option, the OpenAPI spec allows the community to create implementations for Remote Caching of their own.

We’ve published the Remote Cache spec as JSON to the web for some time, and have recently added a human-friendly version of the spec at https://turborepo.dev/docs/openapi.

Visit the Remote Caching documentation to learn more.
