The Problem with Misaligned Dependencies

Developers often face a frustrating issue when working on projects: misaligned dependencies. This can lead to dependency hell, a situation where managing and resolving dependency conflicts becomes a time-consuming and tedious task. Misaligned dependencies can cause bugs, make collaboration difficult, and hinder the overall development process.

In this blog post, we'll discuss how Bit streamlines the management of dependencies in workspaces, helping you maintain consistent and aligned dependencies across your project. We'll also provide a step-by-step guide on how to align dependencies in a Bit workspace and look into the upcoming Ripple feature that will further revolutionize dependency management in component-based projects.

Aligning Dependencies in a Bit Scope - Quick Start

Follow these steps in your Bit workspace.

Import all components from your scope with the asterisk wildcard. For example, the following imports components from the learnbit.aligning-dependencies demo scope:


Run the following to check your workspace status:


Notice that some components are now modified. This is because Bit automatically updates the direct dependencies to the latest version available in the workspace. The card component is now using the latest version of another imported component.

modified components

> learnbit.aligning-dependencies/card ... ok

Then, to update all external dependencies, packages and components that are not maintained in the workspace, run the following command:


You can use the yes flag to automatically confirm the update for all packages.

Let's check the status of the workspace again:


The button is now also listed as modified, since its external dependencies were updated to the latest version.

modified components

> learnbit.aligning-dependencies/card ... ok
> learnbit.aligning-dependencies/button ... ok

Congrats! All components in your scope now have aligned dependencies. ๐ŸŽ‰ Of course you can also create an update that includes components from several scopes by importing from multiple scopes.

Aligning Dependencies in a Scope: A Deep Dive

Dependency Resolution: Bit components vs Packages

When it comes to resolving dependencies, regular packages and Bit components follow different rules. Regular packages can use version ranges to define their dependencies, which allows them to work with multiple compatible versions of another package. For example, the button@0.0.2 component can depend on classnames@^1.2.2 package, where the caret (^) symbol indicates that any version of classnames that is compatible with V1.2.2 can be used.

Bit components, however, always depend on a concrete version of another component. This means that the same button@0.0.2 cannot depend on greet-user@^0.0.2, but rather on a specific version like greet-user@0.0.2. This approach ensures greater consistency and predictability when managing dependencies in a project. By depending on a specific version, components avoid receiving automatic updates that could potentially introduce breaking changes or unexpected behavior.

By understanding the difference between regular packages and Bit components, as well as their respective dependency resolution mechanisms for Bit component dependencies, you can make more informed decisions when managing dependencies in their projects. In the next section, we'll dive into the workflow of aligning dependencies in a scope and discuss how to streamline the process of managing packages and components.

Now let's go back to the demo scope that has three components that have misaligned dependencies. We will analyze the dependency issues and demonstrate how importing components from a scope and updating packages can help align dependencies.

Setting Up the Workspace and Importing Components from the Demo Scope

In the demo scope we have the following components:

button@0.0.2 โž classnames@1.2.2 (uses an old version of the classnames package)

card@0.0.1 โž classnames@2.3.1 (uses the latest version of the classnames package)

card@0.0.1 โž greet-user@0.0.1 (uses an old version of the greet-user component)

button@0.0.2 โž greet-user@0.0.2 (uses the latest version of the greet-user component)

Analyzing Dependency Issues and Aligning Dependencies

After importing the components from the demo scope, you can observe that card@0.0.1 is now using greet-user@0.0.2, as Bit updates the dependencies to the latest version available in the workspace.

You can observe that by running the following command:


But the button component is still using an old version of classnames. When Bit imports components it also installes their dependencies. However, it does not update the dependencies to the latest version available in the workspace.

To update all package dependencies, run the following command:


Now, the card and button components will both use will use classnames@2.3.1, aligning their package dependencies.

You can also observe that before updating, the button creates its own node_modules folder to maintain its dependency on classnames@1.2.2. This occurs due to the nature of hoisting dependencies, where the button component isolates its dependencies to avoid using the newer version of the package. However, updating the package dependencies resolves this issue.

By following the steps outlined in this section, you can effectively identify and address misaligned dependencies in your Bit component-based projects. Aligning dependencies ensures smoother collaboration and reduces potential issues caused by mismatched component or package versions.


In this blog post, we have discussed the importance of aligning dependencies in a Bit component-based project, as well as the workflow and techniques for managing and inspecting dependencies. By aligning dependencies in a scope, you can enjoy several benefits, including:

a. Improved Collaboration and Code Maintenance

Ensuring that all components in a scope are using the same version of dependencies leads to better collaboration among team members. It reduces the chances of conflicts and makes code maintenance more efficient, as all components rely on a consistent set of dependencies.

b. Streamlined Development Workflow

When dependencies are aligned within a scope, it simplifies the development workflow. You can quickly identify and fix issues caused by mismatched dependencies and spend more time focusing on building new features and improving your codebase.

c. Future-proofing Your Bit Components

By consistently aligning dependencies, you create a more robust and future-proof codebase. This approach makes it easier to update components and their dependencies when new versions are released, ensuring that the codebase stays up-to-date and secure.

By understanding the importance of dependency alignment and adopting best practices for managing and inspecting dependencies, you can create more efficient, maintainable, and future-proof component-based projects.

A Glimpse into the (Near) Future: Ripple, the CI for Components

In the near future, Bit will introduce Ripple, a Continuous Integration (CI) system specifically designed for components. Ripple will revolutionize the way you manage and update components in your scope, making the process even more efficient and streamlined.

Here's a quick overview of what Ripple has to offer:

  • Automated Updates for Components in Your Scope: When you create a workspace and import only a single component, like greet-user, then tag and export it to, Ripple will automatically build it on the cloud. Once the build finishes, Ripple will propagate the updates to all its dependents, such as the card and button components. This automation ensures that your components are always up-to-date with the latest changes and improvements.
  • Cross-Scope Updates Preview: Ripple also offers the option to preview updates from components used from other scopes (teams). When a team updates a component you're using in your project, you can preview the changes on the cloud and decide if you want to accept the update. This feature allows you to maintain control over the dependencies in your project, ensuring that you're only using the best and most compatible versions of components.

Ripple will bring a new level of automation and flexibility to Bit component-based projects. By automating updates and providing cross-scope update previews, you'll be able to keep your codebase up-to-date and secure while maintaining control over your dependencies. With Ripple, managing and updating components in your scope will become easier than ever, helping you build more efficient, maintainable, and future-proof projects.
