Template Literal Types

Template Literal Types in TypeScript build upon string literal types, offering the ability to expand into multiple strings via unions. They share the same syntax as template literal strings in JavaScript but are used in type positions.

Key Features:

• String Manipulation: Define new strings based on information within a type.
• Type Inference: Use generics to capture literal types and validate attributes.
• Intrinsic String Manipulation: Includes built-in types like Uppercase, Lowercase, Capitalize, and Uncapitalize for string transformations.

Use Cases:

• Event Name Generation: Automatically create event names by combining attribute names with suffixes like "Changed".
• Data Type Enforcement: Ensure callback functions receive arguments of the correct type based on attribute types.
• Code Validation: Prevent common errors by enforcing type constraints on event names and callback arguments.
• String Transformations: Useful for standardizing string formats, such as converting keys to uppercase for cache IDs.
