Build

Builds are packages of Functions and Assets that you bundle together for deployment. Builds contain Function Version SIDs, Asset Version SIDs, and Dependencies.

Dependencies are defined as JSON strings, for example:

1'[{"name": "randomcolor","version":"0.5.4" },
2 {"name": "util","version":"0.10.3" },
3 {"name": "xmldom","version":"0.1.27" },
4 {"name": "got","version":"6.7.1" },
5 {"name": "fs","version":"0.0.1-security" },
6 {"name": "lodash","version":"4.17.11" },
7 {"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.

You must specify all Function or Asset Versions when creating a Build. Builds only use the provided Versions, and do not reference the Versions used by previous Builds.

(warning)

Warning

In order to create a Build successfully, your request must include at least one Function Version, Asset Version, or a combination of both.

If no Function or Asset Versions are indicated, you'll receive Error 20001:

At least one Function Version or Asset Version is required for Build
