dbt deps: Efficient Dependency Management

The dbt deps command helps with managing dependencies within dbt projects. It retrieves the latest versions of the dependencies listed in your packages.yml file from their respective sources.

How dbt deps Works

Upon execution, dbt deps checks the packages.yml file for listed dependencies and attempts to pull the most recent versions available from the specified sources:

From dbt Hub: It fetches the version specified and informs if any updates are available.
From Git repositories: It pulls the specified branch, tag, or commit from the repository, ensuring the project uses the exact version required.

Example Configuration and Output

Consider the following packages.yml setup:

packages.yml

packages:
  - package: dbt-labs/dbt_utils
    version: 1.2.0
  - package: dbt-labs/codegen
    version: 0.12.1
  - package: calogica/dbt_expectations
    version: 0.10.3
  - git: https://github.com/goes-funky/dbt-data-reliability.git
    revision: 97ec44895f0926954fb7303929a95bea0105f0ae

Running dbt deps with this configuration would produce the following output:

10:15:12  Installing dbt-labs/dbt_utils
10:15:12  Installed from version 1.2.0
10:15:12  Up to date!
10:15:12  Installing dbt-labs/codegen
10:15:12  Installed from version 0.12.1
10:15:12  Up to date!
10:15:12  Installing calogica/dbt_expectations
10:15:13  Installed from version 0.10.3
10:15:13  Up to date!
10:15:13  Installing https://github.com/goes-funky/dbt-data-reliability.git
10:15:16  Installed from revision 97ec44895f0926954fb7303929a95bea0105f0ae
10:15:16  Installing calogica/dbt_date
10:15:16  Installed from version 0.10.1
10:15:16  Up to date!

This output details the installation status for each package and indicates whether the installed version is up-to-date or if a newer version is available.
