Use the Dataform CLI

Guide to learn how to use the Dataform command line interface tool.

The CLI enables you to initialize, compile, test, and run Dataform projects directly from your local machine or as part of other systems.


The Dataform CLI can be installed using NPM:

1npm i -g @dataform/cli

Create a new project

To create a new bigquery , postgres , redshift , snowflake , or sqldatawarehouse project in the new_project directory, run the respective command:

1dataform init bigquery new_project --default-database <your-google-cloud-project-id>
2- or -
3dataform init postgres new_project
4- or -
5dataform init redshift new_project
6- or -
7dataform init snowflake new_project
8- or -
9dataform init sqldatawarehouse new_project
10- or, if you've cloned a pre-existing project -
11dataform install

Project structure

Change directory into the newly-created new_project directory and take a look at your newly created project files:

1cd new_project

You should see the following structure:

2├── definitions
3├── includes
4├── package.json
5└── dataform.json

Define a dataset

The definitions/ directory should be used for files that define tables, assertions, and operations.

To create a new dataset, create a new file definitions/example.sqlx :

1echo "config { type: 'view' } SELECT 1 AS test" > definitions/example.sqlx

Compile your code

To check that your Dataform code compiles, run the compile command at the root of your project directory to get JSON output of the compiled project:

1dataform compile

You should see output similar to the following:

3Compiled 1 action(s).
41 dataset(s):
5  dataform.example [view]

To see the output of the compilation process as a JSON object, add the --json option.

1dataform compile --json

If your project uses custom compilation variables, you can pass their values using the --vars flag:

1dataform compile --vars=exampleVar=exampleValue,foo=bar

Create a credentials file

Dataform requires a credentials file in order to connect to your warehouse. Run the init-creds command and Dataform will guide you through credentials file creation:

1dataform init-creds bigquery
2- or -
3dataform init-creds postgres
4- or -
5dataform init-creds redshift
6- or -
7dataform init-creds snowflake
8- or -
9dataform init-creds sqldatawarehouse

A .df-credentials.json file will be written to disk containing your provided details.

Check out our data warehouse setup guide if you need help with the init-creds wizard.

If using a source control system, we strongly recommend that you do not commit the{" "} .df-credentials.json file to your repository in order to protect these access credentials.

Run your code

In order to run your code, Dataform needs to access your data warehouse in order to determine its current state and tailor the resulting SQL accordingly. If you'd like to see the final SQL that Dataform will run on your warehouse without actually running it, you can perform a dry run:

1dataform run --dry-run

You should see something similar to the following:

3Compiled successfully.
5Dry run (--dry-run) mode is turned on; not running the following actions against your warehouse:
71 dataset(s):
8  dataform.example [table]

Removing the --dry-run option will result in the SQL being run in your warehouse:

1dataform run

The run command's output will now include the run's execution status, including any errors encountered during the run:

3Compiled successfully.
7Dataset created:  dataform.example [view]

Get help

In addition to this guide, you can run the help command to get a short description of any Dataform command or option. For example, you can type:

1dataform help

This will list all of the available commands and options:

2  dataform help [command]                                 Show help. If [command] is specified, the help is for the given command.
3  dataform init <warehouse> [project-dir]                 Create a new dataform project.
4  dataform init-creds <warehouse> [project-dir]           Create a .df-credentials.json file for dataform to use when accessing your warehouse.
5  dataform compile [project-dir]                          Compile the dataform project. Produces JSON output describing the non-executable graph.
6  dataform test [project-dir]                             Run the dataform project\'s unit tests on the configured data warehouse.
7  dataform run [project-dir]                              Run the dataform project\'s scripts on the configured data warehouse.
8  dataform listtables <warehouse>                         List tables on the configured data warehouse.
9  dataform gettablemetadata <warehouse> <schema> <table>  Fetch metadata for a specified table.
12  --help     Show help  [boolean]
13  --version  Show version number  [boolean]

If you want to get help for a specific command, you can type:

1dataform help compile

You should see something similar to the following:

1dataform compile [project-dir]
3Compile the dataform project. Produces JSON output describing the non-executable graph.
6  project-dir  The Dataform project directory.  [default: \".\"]
9  --help           Show help  [boolean]
10  --version        Show version number  [boolean]
11  --watch          Whether to watch the changes in the project directory.  [boolean] [default: false]
12  --schema-suffix  A suffix to be appended to output schema names.
13  --verbose        If true, the full contents of command output will be output (containing fully compiled SQL, etc).  [boolean] [default: false]
