En este documento se explica cómo usar la interfaz de línea de comandos (CLI) de código abierto de Dataform para desarrollar flujos de trabajo de forma local mediante la terminal.
Con la CLI de código abierto de Dataform, puedes inicializar, compilar, probar y ejecutar Dataform Core de forma local, fuera de Google Cloud.
La CLI de Dataform admite las credenciales predeterminadas de la aplicación (ADC).
Con ADC, puedes poner las credenciales a disposición de tu aplicación en varios entornos, como el de desarrollo local o el de producción, sin necesidad de modificar el código de la aplicación. Para usar ADC, primero debes proporcionar tus credenciales a ADC.
Antes de empezar
Antes de instalar la CLI de Dataform, instala NPM.
Instalar la CLI de Dataform
Para instalar la CLI de Dataform, ejecuta el siguiente comando:
npm i -g @dataform/cli@^3.0.0-beta
Inicializar un proyecto de Dataform
Para inicializar un proyecto de Dataform, ejecuta el siguiente comando en el directorio del proyecto:
dataform init . PROJECT_NAMEDEFAULT_LOCATION
Haz los cambios siguientes:
PROJECT_NAME: el nombre de tu proyecto.
DEFAULT_LOCATION: la región en la que quiere que Dataform escriba los datos de BigQuery. Para obtener más información sobre las regiones de BigQuery, consulta las ubicaciones de BigQuery.
Actualizar el núcleo de Dataform
Para actualizar el framework principal de Dataform, actualiza el archivo dataformCoreVersion
en workflow_settings.yaml y vuelve a ejecutar la instalación de NPM:
npm i
Actualizar la CLI de Dataform
Para actualizar la herramienta de línea de comandos de Dataform, ejecuta el siguiente comando:
npm i -g @dataform/cli@^3.0.0-beta.2
Crear un archivo de credenciales
Dataform requiere un archivo de credenciales para conectarse a servicios remotos y crear el archivo .df-credentials.json en tu disco.
Para crear el archivo de credenciales, sigue estos pasos:
Ejecuta el siguiente comando:
dataform init-creds
Sigue el asistente init-creds, que te guiará en el proceso de creación del archivo de credenciales.
Crear un proyecto
Un proyecto de Dataform vacío en Dataform core 3.0.0-beta.0
o versiones posteriores tiene la siguiente estructura:
project-dir
├── definitions
├── includes
└── workflow_settings.yaml
Para crear un proyecto de Dataform con el que desplegar recursos en BigQuery, ejecuta el siguiente comando:
YOUR_GOOGLE_CLOUD_PROJECT_ID: tu ID de proyecto Google Cloud .
DEFAULT_LOCATION: la región en la que quiere que Dataform escriba los datos de BigQuery. Para obtener más información sobre las regiones de BigQuery, consulta las ubicaciones de BigQuery.
Clonar un proyecto
Para clonar un proyecto de Dataform desde un repositorio de Git de terceros, sigue las instrucciones de tu proveedor de Git.
Una vez que se haya clonado el repositorio, ejecuta el siguiente comando en el directorio del repositorio clonado:
dataform install
Definir una tabla
Almacena las definiciones en la carpeta definitions/.
Para definir una tabla, ejecuta el siguiente comando:
[[["Es fácil de entender","easyToUnderstand","thumb-up"],["Me ofreció una solución al problema","solvedMyProblem","thumb-up"],["Otro","otherUp","thumb-up"]],[["Es difícil de entender","hardToUnderstand","thumb-down"],["La información o el código de muestra no son correctos","incorrectInformationOrSampleCode","thumb-down"],["Me faltan las muestras o la información que necesito","missingTheInformationSamplesINeed","thumb-down"],["Problema de traducción","translationIssue","thumb-down"],["Otro","otherDown","thumb-down"]],["Última actualización: 2025-08-21 (UTC)."],[[["\u003cp\u003eThe Dataform CLI allows for local development of SQL workflows, enabling users to initialize, compile, test, and run Dataform core outside of Google Cloud.\u003c/p\u003e\n"],["\u003cp\u003eThe Dataform CLI supports Application Default Credentials (ADC) for managing credentials across different environments without code modification.\u003c/p\u003e\n"],["\u003cp\u003eDataform projects can be initialized, cloned, and managed locally, and the CLI provides commands to define tables, manual assertions, and custom SQL operations.\u003c/p\u003e\n"],["\u003cp\u003eUsers can compile code and view the output in real-time, either in the terminal or as a JSON object, including options for custom compilation variables.\u003c/p\u003e\n"],["\u003cp\u003eThe CLI facilitates code execution, dry runs, and full refreshes in BigQuery, with commands available to get help on specific command options.\u003c/p\u003e\n"]]],[],null,["This document shows you how to use the open-source Dataform command-line interface (CLI) to locally develop workflows by using the terminal.\n\n\u003cbr /\u003e\n\nWith the open-source Dataform CLI, you can initialize, compile, test,\nand run [Dataform core](/dataform/docs/overview#dataform-core) locally,\noutside of Google Cloud.\n\nThe Dataform CLI supports [Application Default Credentials (ADC)](/docs/authentication/application-default-credentials).\nWith ADC, you can make credentials available to your application in a variety\nof environments, such as local development or production, without needing to\nmodify your application code.

You can build your own Docker image of Dataform, which you can use to run the equivalent of Dataform CLI commands. To build your own Docker image, see [Containerize an application](https://docs.docker.com/guides/workshop/02_our_app/) in the Docker documentation.\n\nBefore you begin\n\nBefore installing the Dataform CLI, install\n[NPM](https://www.npmjs.com/get-npm).\n\nInstall Dataform CLI\n\n- To install Dataform CLI, run the following command:\n\n npm i -g @dataform/cli@^3.0.0-beta\n\nInitialize a Dataform project\n\n- To initialize a new Dataform project,\n run the following command inside your project directory:\n\n dataform init . \u003cvar translate=\"no\"\u003ePROJECT_NAME\u003c/var\u003e \u003cvar translate=\"no\"\u003eDEFAULT_LOCATION\u003c/var\u003e\n\n Replace the following:\n - \u003cvar translate=\"no\"\u003ePROJECT_NAME\u003c/var\u003e: the name of your project.\n - \u003cvar translate=\"no\"\u003eDEFAULT_LOCATION\u003c/var\u003e (optional): the location where\n you want Dataform to write BigQuery data. If unset,\n Dataform determines the location based on the datasets that\n your SQL query references. This works as follows:\n\n - If your query references datasets from the same location, Dataform uses that location.\n - If your query references datasets from two or more different locations, an error occurs. For details about this limitation, see [Cross-region dataset replication](/bigquery/docs/data-replication).\n - If your query doesn't reference any datasets, the default location for Dataform is the `US` multi-region. To choose a different location, set the default location. Alternatively, use the [`@@location` system variable](/bigquery/docs/reference/system-variables) in your query. For more information, see [Specify locations](/bigquery/docs/locations#specify_locations).\n\nUpdate Dataform core\n\n- To update the Dataform core framework, update the `dataformCoreVersion`\n in `workflow_settings.yaml` file, then re-run NPM install:\n\n npm i\n\nUpdate Dataform CLI\n\n- To update the Dataform CLI tool, run the following command:\n\n npm i -g @dataform/cli@^3.0.0-beta.2\n\nCreate a credentials file\n\nDataform requires a credentials file to connect to remote services\nand create the `.df-credentials.json` file on your disk.\n| **Warning:** If you use a source control system, don't commit the `df-credentials.json`. file to your repository to protect these access credentials. We recommend that you add the `.df-credentials.json` file to `.gitignore`.\n\nTo create the credentials file, follow these steps:\n\n1. Run the following command:\n\n dataform init-creds\n\n2. Follow the `init-creds` wizard that walks you through credentials file creation.\n\nCreate a project\n\nAn empty Dataform project in Dataform core `3.0.0-beta.0`\nor later has the following structure: \n\n project-dir\n ├── definitions\n ├── includes\n └── workflow_settings.yaml\n\n- To create a Dataform project to deploy assets to\n BigQuery, run the following command:\n\n dataform init \u003cvar translate=\"no\"\u003ePROJECT_NAME\u003c/var\u003e --default-database \u003cvar translate=\"no\"\u003eYOUR_GOOGLE_CLOUD_PROJECT_ID\u003c/var\u003e --default-location \u003cvar translate=\"no\"\u003eDEFAULT_LOCATION\u003c/var\u003e\n\n Replace the following:\n - \u003cvar translate=\"no\"\u003ePROJECT_NAME\u003c/var\u003e: the name of your project.\n - \u003cvar translate=\"no\"\u003eYOUR_GOOGLE_CLOUD_PROJECT_ID\u003c/var\u003e: your Google Cloud project ID.\n - \u003cvar translate=\"no\"\u003eDEFAULT_LOCATION\u003c/var\u003e (optional): the location where you\n want Dataform to write BigQuery data.
