5. Introduction To Packaging
● Packaging allows you to group various Salesforce Components (Apps ,
Tabs , Objects , Layouts , Workflows, Approval Process Flows , visualforce ,
apex , lightning components , profiles , permission sets and other
metadata) for distribution or deployment .
● A package can also be defined as a container and allows for
deployment of the components across various salesforce organizations.
● Salesforce Set up UI and Salesforce CLI allows for creation of these
● Package Creation yields a URL that allows it to install in various orgs

6. Differentiate between Unmanaged packages ,
Managed packaged and Unlocked packages
Unmanaged
Package
Not upgradable
Metadata elements are not IP
Protected
Can we created in Salesforce
UI
Unmanaged package
containers automatically pull
dependency
Managed
Package
Upgradable and has
namespace
Metadata elements are IP
Protected
Can be created in salesforce UI
and distributed via
appexchange
Components are locked and
one cannot modify them
directly in production or
sandbox
Allows for creation of extension
packages
Unlocked
Package
Upgradable and one can
namespace them or choose
not to
Metadata elements are not
locked and can be changed
by system admins
Requires Salesforce CLI to
generate them
Allows you to build your
applications in a modular way
Easier to manage when
codebase is modularized

7. Modular Application
Development Concepts
● Break Your one monolithic app to
multiple packages defining
dependency between them .
● Unlock packages allow you to do them

8. Building Unlocked packages using Salesforce CLI
● Unlocked packages cannot be created using salesforce UI and requires knowledge of salesforce
CLI and requires source code in DX Source format .
● Scratch orgs are not required but a DevHub is mandatory . However scratch orgs are
recommended since the deployment to them is faster .
● One can create a package using below
sfdx force:package:create --name <name> --description <description> --packagetype Unlocked --
path force-app --nonamespace --targetdevhubusername <Devhubalias>
● Create a package version as below
sfdx force:package:version:create -p <packagename> -d force-app --wait 10 -v <Devhubalias>

9. Publishing and Installing Unlocked packages
● sfdx-project.json defines the Version Name and version number
● Installing can be using the Subscriber Package Version Id
● Installation can also be done via the Salesforce CLI
sfdx force:package:install --wait 10 --publishwait 10 --package <packagename>@1.0.0-1 -r
-u <alias>
● By Default a BETA package is generated . We can promote a package using below
sfdx force:package:version:promote -p <packagename>@1.0.0-1 -v <DevHubalias>

10. Creating Dependency between packages
● sfdx-project.json can be used to define dependency between packages
