Storybook best practices for making the most out of Nx

Purpose of this guide

The purpose of this guide is to help you set up Storybook in your Nx workspace so that you can get the most out of Nx and its powerful capabilities.

When to use Storybook

Usually, Storybook is mainly used for two reasons. Testing and documentation. You can read more on when and why to use Storybook in the Why Storybook in 2022? article and also in the Introduction to Storybook documentation page.


Storybook helps you test your UIs. You can read more about testing with Storybook in the How to test your UIs with Storybook documentation page. Essentially, Storybook uses the stories as a starting point for testing.


Storybook helps you document your UI elements, or your design system, effectively and in an interactive way. You can read more in the How-to document components documentation page. Essentially, you can use Storybook to publish a catalog of your components. A catalog that you can share with the design team, the developer team, the product team, anyone else in the product development process, or even the client. The components are isolated, interactive, and can be represented in all possible forms that they can take (e.g. for a button: enabled, disabled, active, etc). You can read more about publishing your Storybook in the Publish Storybook documentation page.

Nx and Storybook

Now let’s see how Nx can be used to accommodate both of these pillars of Storybook. Nx takes lots of the burden off your arms when setting up Storybook initially. It essentially provides you with all that you need to start using Storybook’s capabilities (testing and documentation) right away, without having to write a single line of code.

Development tools

First, let’s see what Nx offers, when you are in the process of developing a project with Storybook.

Configuration generation

You can generate the Storybook configuration files and settings using the Nx @nx/storybook:configuration generator. You can read more about configuring Storybook with Nx in our @nx/storybook package overview page. With Nx, you configure Storybook for each individual project.

Stories generation

If you are on a project using Angular, React or React Native, you can also generate stories for your components. You can do so either by using each package's storybook-configuration generators or by using the stories generator, if you already have Storybook configured for your project.

If your project is not configured yet, check out one of these guides:

If your project is already configured, you can use the stories generator:

The stories generator will read your inputs (if you’re using Angular), or your props (if you're using React), and will generate stories with the corresponding arguments/controls already prefilled.

Cypress tests generation

Nx also generates Cypress tests for your components, that point to the corresponding component’s story. You can read more about how the Cypress tests are generated and how they look like in the storybook-configuration generator documentation.

Take a look at the generated code of the Cypress test file, specifically at the URL which Cypress visits:

cy.visit( '/iframe.html?id=buttoncomponent--primary&args=text:Click+me!;padding;style:default' );

Cypress visits the URL that hosts the story of the component we are testing, adding values to its controls (eg. args=text:Click+me!). Then, the test attempts to validate that the values are correctly applied.

CI/CD tools

Now let’s see how Nx helps in the CI/CD journey, as well.

Cypress testing

When you are running the Cypress tests for a project, Cypress will start the Storybook server of that project. The Storybook server will fire up a Storybook instance, hosting all the components's stories for that project. The e2e tests will then run, which actually visit the stories and perform the tests there. Cypress will be configured to start and stop the Storybook server. The results will be cached, and they will go through the Nx graph, meaning that Nx will know if the tests need to be run again or not, depending on the affected status of your project.


When you are configuring Storybook, Nx adds a serve and a build target for Storybook in your project.json, as we explained above. You can use these targets to serve and build storybook locally, and also in production. Cypress will also use these targets when firing up the e2e tests. While developing, you can serve your Storybooks locally to see if your components work and look as expected. This can help you and speed up the development and debugging process (no need to fire up a complex dev stack).

Build and deploy

The build and deploy step usually comes in handy when you are ready to use Storybook for documentation, and you want to publish it. The building step of Storybook is integrated in the Nx ecosystem, as explained above, and you can trigger your Storybook builds as you would trigger any other build inside your workspace.

When you publish your organization’s Storybook, as a result, ideally, you would want to have one shareable Storybook page/application living under one URL, that you can share. With Nx, you can build your Storybook and it will be ready for deployment. However, at this point, you have one Storybook per project in your workspace, and you could end up with far too many Storybooks that are built and ready for deployment. This is not ideal, and does not accomplish the ultimate goal of “one shareable documentation page”.

In the following section, we are going to see how to set up Storybook in these cases, to get the most out of Nx.

How to set up Storybook to get the most out of Nx


Setting up Storybook on Nx reflects - and takes advantage of - the mental model of Nx, and especially the architecture of Applications and Libraries. What that means, in essence, is that you still maintain the individual Storybook instances (per project) which you use for testing and local development, but you also keep one extra “container” for publishing, that serves as a single entry point. Let’s see this in more detail.

Local development and testing

Development and debugging

In the process of setting up Storybook in your Nx workspace that we described above, you end up with one Storybook instance per project. That way, you can use your project’s Storybook targets to serve and build Storybook:

nx storybook my-project


nx build-storybook my-project

This feature is extremely useful when developing locally. The containerized stories in your Storybook are the only ones that are built/served when you want to debug just one component, or just one library. You don’t have to wait for a huge Storybook containing all your stories in your repository to fire up. You just need to wait for the Storybook of a single project to start. This speeds up the process.

E2e tests with Cypress

If you’re using Cypress, and you’re taking advantage of the generated Cypress tests that our Storybook generators generate, then your e2e tests are also going to be much faster. When you run your e2e tests for a particular project, Cypress is only going to start the specific Storybook instance, and it’s going to take much less time than having to start an all-including universal Storybook.

Caching, affected, dependency management

Since each Storybook, in this case, is attached to a project, so is the serving of Storybook and the building of Storybook and the e2e tests for that project. That means that Nx is aware of these tasks, so it caches them, it knows when to fetch them from the cache or re-run them according to the affected status of that project. It also knows that project’s dependencies and knows which things to rebuild before each task.


When you are publishing your Storybook, you can follow the same principles described in the Applications and Libraries Mental Model documentation page. The general idea is to have one central Storybook container, into which you are going to gather your stories from multiple libraries.

You can think of the central Storybook container as a grouping of similar-concept or same-scope UI parts of your workspace. In the same way you are scoping libraries, you can group your stories as well.

Then, according to your use-case, you can have one central Storybook for your whole workspace, importing all the stories from all the projects. Alternatively, you can have one Storybook per "scope", which imports all the stories from projects the same scope. Or even one Storybook per application, importing all the stories of all the libraries that it is depending on. As you can see, there are many options, and you can choose the one that best suits your needs.

Storybook Composition

In order to achieve some things mentioned above, you may use Storybook Composition. However, in this case, you would still need to build each project’s Storybook individually, and also deploy it individually. So in the cases where you have multiple projects, Storybook Composition would not be very efficient.

Before moving on to the examples section, it could be useful to read the Library Types documentation page and the Grouping libraries documentation page. These could help you decide which way fits your use case better.

Examples / Use cases

You can check out the following examples (recipes) to see publishing strategies for Storybook in Nx:


In this guide, we have given a direction towards the most efficient way to use Storybook in a Nx workspace, in a way that takes advantage of the all that Nx has to offer. We have covered the different ways to set up Storybook, and publish it, too. We have also covered the different use cases that apply to each of the solutions.
