The dependencies property is a JSON object field (dependencies) in the app's manifest.json file.

This field specifies which VTEX IO apps your app relies on to properly work. Its semantics resembles package.json's dependencies property on Javascript apps.

In practice, when an app is installed on a VTEX account, every app included in its manifest's dependencies field is automatically installed on the account.

Therefore, if your app needs to interact with another IO app, such as a VTEX API or a store framework block, you may declare it in the manifest.json file under dependencies, according to the following structure "{account}.{appName}": "{majorVersion}.x".

The dependencies object of your app's manifest.json file may look something like this:

The most recurrent use of VTEX IO apps as dependencies are for:

• Using VTEX Store Framework blocks.
• Importing React components from another app.
• Importing Typescript types from a GraphQL service app.
• Using GraphQL or REST definitions declared in another app.
• Implementing a GraphQL schema from another app.

When installing a VTEX IO app, its dependencies will be automatically installed on the logged account as well, but not as first-class apps. That means that indirect dependencies won't be able to declare routes.
