# List package version assets
<a name="list-assets"></a>

An *asset* is an individual file (for example, an npm `.tgz` file or Maven POM or JAR file) stored in CodeArtifact that is associated with a package version. You can use the `list-package-version-assets` command to list the assets in each package version.

Run the `list-package-version-assets` command to return the following information about each asset in your AWS account and your current AWS Region:
+  Its name. 
+  Its size, in bytes. 
+  A set of hash values used for checksum validation. 

For example, use the following command to list the assets of the Python package `flatten-json`, version `0.1.7`.

```
aws codeartifact list-package-version-assets --domain {{my_domain}} --domain-owner {{111122223333}} \
 --repository {{my_repo}} --format {{pypi}} --package {{flatten-json}} \
 --package-version {{0.1.7}}
```

The following shows the output.

```
{
    "format": "{{pypi}}",
    "package": "{{flatten-json}}",
    "version": "{{0.1.7}}",
    "versionRevision": "REVISION-SAMPLE-1-C7F4S5E9B772FC",
    "assets": [

        }
    ]
}

## List assets of an npm package
<a name="list-assets-npm"></a>

An npm package always has a single asset with a name of `package.tgz`. To list the assets of a scoped npm package, include the scope in the `--namespace` option.

```
aws codeartifact list-package-version-assets --domain {{my_domain}} --domain-owner {{111122223333}} \
 --repository {{my_repo}} --format {{npm}} --package {{webpack}} \
 --namespace {{types}} --package-version {{4.9.2}}
```

## List assets of a Maven package
<a name="list-assets-maven"></a>

To list the assets of a Maven package, include the package namespace in the `--namespace` option. To list the assets of the Maven package `commons-cli:commons-cli`:

```
aws codeartifact list-package-version-assets --domain {{my_domain}} --domain-owner {{111122223333}} \
 --repository {{my_repo}} --format {{maven}} --package {{commons-cli}} \
 --namespace {{commons-cli}} --package-version {{1.0}}
```
