Dataform Deployment Best Practices

Are you tired of struggling with data management? Do you want to streamline your data workflows and make your life easier? Look no further than Dataform, the powerful data management tool that can help you take control of your data.

But before you start using Dataform, it's important to understand the best practices for deploying it. In this article, we'll cover everything you need to know about Dataform deployment best practices, from setting up your environment to optimizing your workflows.

Setting Up Your Environment

The first step in deploying Dataform is setting up your environment. This includes installing the necessary software and configuring your system to work with Dataform.

Installing Dataform

To install Dataform, you'll need to have Node.js and npm installed on your system. Once you have these installed, you can install Dataform using the following command:

npm install -g dataform

This will install Dataform globally on your system, allowing you to use it from anywhere.

Configuring Your System

Before you can start using Dataform, you'll need to configure your system to work with it. This includes setting up your database connections and configuring your project settings.

Database Connections

Dataform supports a variety of databases, including PostgreSQL, BigQuery, and Snowflake. To connect to your database, you'll need to provide the necessary credentials in your Dataform configuration file.

For example, if you're using PostgreSQL, your configuration file might look like this:

# dataform.json

  "warehouse": "postgres",
  "defaultSchema": "public",
  "connections": {
    "postgres": {
      "type": "postgres",
      "host": "localhost",
      "port": 5432,
      "database": "mydatabase",
      "username": "myusername",
      "password": "mypassword"

Project Settings

In addition to configuring your database connections, you'll also need to configure your project settings. This includes specifying the location of your project files and setting up your project dependencies.

For example, your project settings might look like this:

# dataform.json

  "projectConfig": {
    "schema": "myproject",
    "dependencies": [
  "paths": {
    "modules": "modules",
    "models": "models"

Optimizing Your Workflows

Once you have your environment set up, it's time to start optimizing your workflows. This includes using best practices for organizing your project files, managing your dependencies, and testing your code.

Organizing Your Project Files

One of the most important best practices for deploying Dataform is organizing your project files. This includes separating your code into modules and models, and using a consistent naming convention.


Modules are reusable pieces of code that can be used across multiple models. They should be stored in a separate directory, and should be named using PascalCase.

For example, a module that calculates the average of a set of numbers might be named Average.js.


Models are the core of your Dataform project. They should be stored in a separate directory, and should be named using snake_case.

For example, a model that calculates the average of a set of numbers might be named average.sql.

Managing Your Dependencies

Another important best practice for deploying Dataform is managing your dependencies. This includes using a package manager to install and manage your dependencies, and keeping your dependencies up to date.

Using a Package Manager

Dataform supports both npm and yarn as package managers. You should use one of these package managers to install and manage your dependencies.

For example, to install a dependency using npm, you would use the following command:

npm install mydependency

Keeping Your Dependencies Up to Date

It's important to keep your dependencies up to date to ensure that your project is using the latest and most secure versions of your dependencies. You can use a package manager to update your dependencies.

For example, to update a dependency using npm, you would use the following command:

npm update mydependency

Testing Your Code

Finally, it's important to test your code to ensure that it's working as expected. This includes writing unit tests for your modules and models, and running these tests regularly.

Writing Unit Tests

Unit tests are tests that verify the behavior of individual pieces of code, such as modules and models. You should write unit tests for all of your code to ensure that it's working as expected.

For example, a unit test for the Average module might look like this:

// Average.test.js

const { expect } = require("chai");
const Average = require("./Average");

describe("Average", () => {
  it("calculates the average of a set of numbers", () => {
    const numbers = [1, 2, 3, 4, 5];
    const expected = 3;
    const actual = Average(numbers);

Running Your Tests

You should run your tests regularly to ensure that your code is working as expected. You can use a test runner to run your tests.

For example, to run your tests using mocha, you would use the following command:



Deploying Dataform can be a powerful tool for managing your data workflows. By following these best practices for setting up your environment and optimizing your workflows, you can streamline your data management and make your life easier. So what are you waiting for?
