Features

• Type Transformations - Provides a comprehensive toolkit for performing complex type transformations on objects, unions, and tuples.
• TypeScript Utility Libraries - Acts as a comprehensive collection of advanced type-level helpers for manipulating objects, unions, and functions.
• Object Merging - Provides utilities for deep merging and reshaping complex object structures at the type level.
• Type Modifier Utilities - A utility that modifies properties on object types by making them optional, required, or readonly.
• Object Type Transformations - Provides utilities for deep merging, patching, and reshaping complex object structures at the type level.
• Function Type Engineering - Implements utilities for currying, composition, and signature extraction to create flexible API patterns.
• String Literal Type Manipulations - Includes utilities for manipulating string literal types through joining, splitting, and length calculation.
• Tuple and Array Type Transformations - Provides type-level operations to append, filter, reverse, or zip tuple and array structures.
• Type-Level Arithmetic - Performs mathematical calculations like sums and absolute values within the TypeScript type system.
• Type Transformation Toolkits - Ships a set of utilities to perform complex computations on literal types, tuples, and string literals.
• Type Transformations - Implements compile-time utilities for modifying types through operations like merging, picking, and omitting.
• Union Type Transformations - Calculates union types by excluding, extracting, filtering, or intersecting their members.
• Collection Transformations - Provides utilities for filtering, excluding, and flattening collections of types to derive new sets of permissible values.
• Union Member Filtering - Filters, excludes, or extracts members from a union type based on a specific condition.
• Union Set Operations - Removes all members of one union type from another to return only unique elements.
• Function Type Transformers - Provides a specialized utility for currying, composing, and extracting signatures from advanced function types.
• Mapped Type Transformations - Implements methods for iterating over object keys and union members to dynamically reconstruct type structures.
• Object Property Type Extractors - Provides utilities to derive the specific type of a value associated with a given key from an object, array, or union.
• Object Property Autocomplete - Provides autocomplete for string-based paths used to access deeply nested object properties.
• Asynchronous Type Extraction - Implements a utility to retrieve the underlying value type wrapped by a Promise for type-safe asynchronous handling.
• Type-Level Merging - A utility that combines multiple lists into one from left to right where subsequent items override preceding ones.
• Object Path Merging - Completes the fields of an object at a specified path using fields from another object.
• Function Currying - Transforms multi-argument functions into a sequence of single-argument functions using placeholders.
• Character Indexing - Retrieves the character located at a specified numeric index within a string literal type.
• String Metric Computations - Computes the number of characters in a string literal type for use in static constraints.
• Type Relationship Verification - Asserts that two types are identical at compile time to ensure type-level logic remains correct.
• Type Signature Extractions - Extracts parameters and return values from function types while allowing behavior modification.
• Type-Safe Path Autocomplete - Provides type-safe string paths for accessing nested object properties with full IDE autocomplete.
• Key Presence Validation - A utility that ensures that at least one specific key from a provided set is present in an object.
• Function Signature Manipulations - Alters function type signatures by currying, composing, or extracting parameter and return types.
• Function Composition - Implements a utility to combine a sequence of operations where the output of one function flows into the next.
• Required Field Enforcement - Removes optional and nullable markers from all properties in an object type to ensure their presence.
• Compile-Time Type Validation - Offers a toolkit for validating type equality and enforcing constraints to ensure correctness during compilation.
• Static - Verifies that complex type computations resolve to expected results during compilation to prevent regressions.
• Type Logic Validation - Provides utilities to execute assertions against type definitions to verify the correctness of complex type computations.
• Type Resolution Testing - Provides utilities to verify that a type resolves to an expected result using assertion tools.
• Type Utilities - Comprehensive collection of type manipulation utilities.
