# Build

Builds are packages of [Functions](/docs/serverless/api/resource/function) and [Assets](/docs/serverless/api/resource/asset) that you bundle together for deployment. Builds contain [Function Version](/docs/serverless/api/resource/function-version) SIDs, [Asset Version](/docs/serverless/api/resource/asset-version) SIDs, and [Dependencies](/docs/serverless/functions-assets/functions/dependencies).

Dependencies are defined as JSON strings, for example:

```bash
'[{"name": "randomcolor","version":"0.5.4" },
 {"name": "util","version":"0.10.3" },
 {"name": "xmldom","version":"0.1.27" },
 {"name": "got","version":"6.7.1" },
 {"name": "fs","version":"0.0.1-security" },
 {"name": "lodash","version":"4.17.11" },
 {"name": "date-fns","version":"1.30.1" }]'
```

Builds take time to package, deploy, and be verified. After creating a Build, it is best to poll every second to check the Build's status. When a Build is verified, it is ready to be used in a Deployment.

## List of Build statuses

| Build status | Meaning                                                             |
| ------------ | ------------------------------------------------------------------- |
| `Building`   | Build request is being processed by the packager.                   |
| `Completed`  | We have run a health check on the uploaded package and verified it. |
| `Failed`     | Packaging has failed at any of the above steps.                     |
