Getting Started with SFDX
SFDX is a set of tools that streamlines the development life cycle. It improves team collaboration, facilitates automated testing, and makes the release cycle more efficient and agile.
To get started with SFDX, follow the steps below:
Step 1: Install the Command Line Interface (CLI)
The Salesforce CLI is an essential tool for controlling the full application life cycle of your Salesforce apps. With it, you can create environments for development and testing, synchronize source code between your orgs and your version control system, and execute tests. To install the Salesforce CLI:
- Download the CLI from here.
- Confirm the CLI is properly installed and is on the latest version by running the following command from the command line: sfdx update and sf update
Step 2: Enable Dev Hub in Your Trailhead Playground
The Developer Hub (Dev Hub) is the main Salesforce org you and your team use to create and manage your scratch orgs. You can enable Dev Hub in any paid org, but practicing in a Developer Edition org or Trailhead Playground is recommended.
Step 3: Get Your Trailhead Username and Password
You'll need your Dev Hub login credentials for Salesforce DX projects. If you don't know the username and password where you enabled Dev Hub, retrieve them.
Step 4: Log In to the Dev Hub
Once the CLI is installed and your Dev Hub is enabled, you can log into your Dev Hub and start working with scratch orgs.
To log in to your Dev Hub enabled org:
- Create an alias for your Dev Hub using -a and make this the default org using -d. Enter the web login flow in the command window to authorize the Dev Hub. The following command opens the Salesforce login page in the web browser: sfdx force:auth:web:login -r https://login.salesforce.com -a YourAlias
- Log in using your Dev Hub org credentials. Please note that this is a special org for Salesforce DX. You must use a Dev Hub-enabled org for this project.
- Click Allow. After you authenticate in the browser, the CLI remembers your Dev Hub credentials.
Step 5: Create a Scratch Org
Scratch orgs are dedicated, configurable, short-term Salesforce environments that you can quickly spin up for new projects, feature branches, or feature tests. To create a scratch org:
- Run the following command: sf org create scratch -d -f config/project-scratch-def.json -a dreamhouse-org. This command creates a scratch org, sets it as your default, and gives it an alias.
- Open the scratch org you just created by running the command: sf org open.
Common SFDX Commands
Here are some common SFDX commands you might find useful:
- sf project deploy start: Deploys a Salesforce DX project into your default org.
- sf org assign permset -n Dreamhouse: Assigns permission set to a user in your default org.
- sf data import tree -p data/sample-data-plan.json: Imports data into your org using the sObject Tree Save API.
Strategies for Efficient Development with SFDX
