The Art and Craft of Type Development
#1about 6 minutes
The challenge of typing deeply nested object properties
Manually creating function overloads for each level of object nesting is not a scalable or dynamic solution for property selection.
#2about 9 minutes
Setting up a playground for advanced type development
Isolate type development by using the TypeScript playground, a sample data object, and a declared function to focus solely on type signatures.
#3about 13 minutes
Recursively generating a union type for nested keys
Build a recursive helper type using string literals and conditional types to generate a union of all possible dot-notation paths for a nested object.
#4about 8 minutes
Inferring the return type from a string path
Use a recursive conditional type with the `infer` keyword to parse a dot-notation string and correctly determine the type of the selected nested property.
#5about 6 minutes
Recapping the workflow and current TypeScript limitations
The development process involves isolating the problem, using helper types, and understanding current limitations like variadic tuple types for dynamic argument lists.
