If the installation was successful, the version number of the Salesforce DX CLI you installed should be displayed.
Setting Up Salesforce DX for the First Time
Now that you have installed Salesforce DX CLI, you need to link it to your Salesforce environment.
- Authenticate your Dev Hub: A Dev Hub is the main Salesforce org that you will use for Salesforce DX. To authenticate, use the following command:
sfdx auth:web:login -d -a MyDevHub
Replace MyDevHub with a name that makes sense for your org.
- Create a Scratch Org: Scratch Orgs are temporary Salesforce orgs where you can perform development and testing. To create one, use:
sfdx force:org:create -s -f config/project-scratch-def.json -a MyScratchOrg
Replace MyScratchOrg with a name suitable for your Scratch Org.
And there you have it! You’ve successfully installed and set up Salesforce DX CLI for the first time.
Essential Salesforce DX CLI Commands
Having installed Salesforce DX CLI and authenticated your Dev Hub, let’s examine some essential commands that you, as a Salesforce developer, will find particularly useful.
This command is used to create a new scratch org from a configuration file. For instance:
sfdx force:org:create -s -f config/project-scratch-def.json -a NewScratchOrg
This command creates a new scratch org with the configuration specified in project-scratch-def.json and sets it as the default username for your project. NewScratchOrg is the alias you’re assigning for easy reference.
This command lists all the authenticated orgs, both scratch orgs and non-scratch orgs.
It’s an excellent way to keep track of all the orgs you have access to and their expiration dates (in case of scratch orgs).
This command is used to authenticate a Salesforce org.
sfdx force:auth:web:login -a MyDevHub
In this example, MyDevHub is the alias you’re assigning to the authenticated org.
This command is used to push source code from your local project to a scratch org.
This is a must-use command after making any changes in your source code to make sure they’re reflected in your scratch org.
This command is used to pull changes from the scratch org to your local project.
Use this command whenever you make changes directly in the scratch org and want them reflected in your local source code.
6 Tips for Using These Commands Effectively
When using Salesforce DX CLI, a few expert tips can help you optimize your development process and harness the full potential of the command line interface:
- Utilize Command Aliases: Always create memorable aliases for your orgs during the creation or authentication process using the -a option. This allows for easier referencing of your orgs in future commands.
- Make Use of the Help Flag: When in doubt, use the -h or –help flag to display a help page with information about a command, its syntax, and the options it accepts.
- Regularly Monitor Your Orgs: Keep track of the status of your orgs using sfdx force:org:list. This allows you to effectively manage your scratch orgs’ lifecycles.
- Embrace Command Autocompletion: Speed up your development process by installing the command auto-completion feature: sfdx plugins:install autocomplete.
- Leverage Scripting: Simplify repetitive tasks by wrapping sequences of commands into shell scripts. This can significantly automate your tasks and increase productivity.
- Check for Updates Regularly: Stay up-to-date with the latest features and bug fixes by regularly checking for updates: sfdx update.
Advanced Commands for Experienced Developers
For seasoned Salesforce developers looking to tackle more complex tasks and automate their workflows, Salesforce DX CLI offers a set of advanced commands. Let’s dive into some of these:
This command is used to deploy metadata to an org from a .zip file or a directory. It’s particularly useful for moving metadata between orgs or migrating metadata to a DX format. Here’s an example:
sfdx force:mdapi:deploy -d path/to/metadata -u TargetOrgAlias
This command deploys metadata from the specified directory to the target org represented by TargetOrgAlias.
This command converts metadata from the Metadata API format into a format compatible with Salesforce DX. For instance:
sfdx force:mdapi:convert -r path/to/metadata
This command converts the metadata in the specified directory and creates a new directory, force-app, in your project to store the converted source.
This command is used to run Apex tests in your Salesforce org.
sfdx force:apex:test:run -u MyDevHub -r human -c -w 10
This command runs all tests in the MyDevHub org and waits up to 10 minutes for the tests to complete. The -r human option outputs the results in an easy-to-read format, and -c gives you code coverage results.
This command is used to execute a SOQL query against your Salesforce org.
sfdx force:data:soql:query -q “SELECT Name, Email FROM Contact” -u MyDevHub
This command runs the specified SOQL query in the MyDevHub org and displays the results.
Troubleshooting Common Issues in Salesforce DX CLI
Like any software tool, Salesforce DX CLI can present some common issues or errors. Here’s a table of a few such issues, their likely causes, and suggested solutions:
ERROR running force:org:create: You do not have access to the [scratch org feature]
You’re not connected to a Dev Hub, or your Dev Hub does not have Dev Hub capabilities enabled.
Connect to a Dev Hub using sfdx force:auth:web:login, and ensure that the Dev Hub capabilities are enabled. If you are unsure how to enable this, refer to the Salesforce documentation.
ERROR running force:source:push: No org configuration found for name [MyScratchOrg]
The specified Scratch Org does not exist, or your current session has expired.
Verify the Scratch Org name or ID. Use sfdx force:org:list to see a list of all authenticated orgs. If the org exists but your session has expired, you can reauthenticate using sfdx force:auth:web:login.
ERROR running force:source:pull: Source was not pulled because the default scratch org is not set
The default Scratch Org is not set.
Set the default Scratch Org using the -s flag when creating the org: sfdx force:org:create -s -f config/project-scratch-def.json -a MyScratchOrg
sfdx force:data:soql:query ERROR: Unable to authenticate to the Dev Hub Org. Please check your default Dev Hub username
The default Dev Hub username is not set, or your current session has expired.
