Package Based Development

Question 1

What is Package Based Development?

Answer 1

• package based development is a model where metadata is organized into unlocked packages
• unlocked packages are versioned groups of related metadata used to migrate customizations between orgs

Question 2

What are the benefits of Package Based Development?

Answer 2

• fits hand-in-glove with Agile software development
• because we’re making different unlocked packages, we can implement iterative and modular development
• separating into multiple packages also increases our understanding of and organization of our metadata
• package versions serve as a log of changes to metadata over time, making easy to audit our development history
• version control happens naturally thanks to it being command line (like Git)

Question 3

What is a Dev Hub?

Answer 3

Dev Hub allows you create and manage scratch Orgs and unlocked packages

Question 4

What is a Scratch Org?

Answer 4

a scratch org is a small, configurable, short-term, disposable development environment that is commonly used with package development

Question 5

What are Unlocked Packages?

Answer 5

unlocked packages allow us to modularize our metadata, but an unlocked package can still depend on other unlocked packages or even managed packages

Question 6

What are some limitations of Package Based Development?

Answer 6

• installing a new version of an unlocked package in any org will overwrite any prior versions of that package and therefore any changes made by admins to the package contents
• unlike some other deployment tools, unlocked packages can be deployed to delete metadata because the CLI tracks all changes, not additions
