🎯 TypeScript Daily Digest!

Today’s edition of Typescript Daily looks at 13 custom real-world type checks/utilities you can make use of right away in your projects.

These utilities range from performing a DeepRequired check on the nested levels and merging multiple object structures, to using conditions as well.

DeepRequired: Make all properties of an object and nested objects required.

Flatten: Flatten a nested object structure into a single level.

FunctionArguments: Extract the argument types from a function type.

EnumValues: Obtain an array of all values from an enum.

GetReturnType: Get the return type of a function, including promises.

OptionalKeys: Extract keys from an object type that corresponds to optional properties.

RequiredKeys: Extract keys from an object type that corresponds to required properties.

Trim: Trim whitespace from all property values of an object.

OptionalExceptFor: Make specific properties required while keeping the rest optional.

ValueOf: Obtain the union type of all property values from an object.

Merge: Combine multiple objects' types into one.

Falsy: Exclude falsy values (e.g., undefined, null, false) from a union type.

NonNullableProperties: Extract a type with all properties of an object that are non-nullable.

These custom TypeScript utility types can help you solve real-world challenges and write more expressive, type-safe code. Feel free to adapt and extend these examples to suit your specific needs.
