You can help by suggesting some of them to the [TypeScript project](https://github.com/Microsoft/TypeScript/blob/master/CONTRIBUTING.md). Either add this package as a dependency or copy-paste the needed types. No credit required. 👌 PR welcome for additional commonly needed types and docs improvements. Read the [contributing guidelines](.github/contributing.md) first. ## Install ``` $ npm install type-fest ``` *Requires TypeScript >=3.4* ## Usage ```ts import {Except} from 'type-fest'; type Foo = { unicorn: string; rainbow: boolean; }; type FooWithoutRainbow = Except<Foo, 'rainbow'>; //=> {unicorn: string} ``` ## API Click the type names for complete docs. ### Basic - [`Primitive`](source/basic.d.ts) - Matches any [primitive value](https://developer.mozilla.org/en-US/docs/Glossary/Primitive). - [`Class`](source/basic.d.ts) - Matches a [`class` constructor](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Classes). - [`TypedArray`](source/typed-array.d.ts) - Matches any [typed array](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/TypedArray), like `Uint8Array` or `Float64Array`. - [`JsonObject`](source/basic.d.ts) - Matches a JSON object. - [`JsonArray`](source/basic.d.ts) - Matches a JSON array. - [`JsonValue`](source/basic.d.ts) - Matches any valid JSON value. - [`ObservableLike`](source/basic.d.ts) - Matches a value that is like an [Observable](https://github.com/tc39/proposal-observable). ### Utilities - [`Except`](source/except.d.ts) - Create a type from an object type without certain keys. This is a stricter version of [`Omit`](https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-5.html#the-omit-helper-type). - [`Mutable`](source/mutable.d.ts) - Create a type that strips `readonly` from all or some of an object's keys. The inverse of `Readonly<T>`. - [`Merge`](source/merge.d.ts) - Merge two types into a new type. Keys of the second type overrides keys of the first type. - [`MergeExclusive`](source/merge-exclusive.d.ts) - Create a type that has mutually exclusive keys. - [`RequireAtLeastOne`](source/require-at-least-one.d.ts) - Create a type that requires at least one of the given keys. - [`RequireExactlyOne`](source/require-exactly-one.d.ts) - Create a type that requires exactly a single key of the given keys and disallows more. - [`PartialDeep`](source/partial-deep.d.ts) - Create a deeply optional version of another type. Use [`Partial<T>`](https://github.com/Microsoft/TypeScript/blob/2961bc3fc0ea1117d4e53bc8e97fa76119bc33e3/src/lib/es5.d.ts#L1401-L1406) if you only need one level deep. - [`ReadonlyDeep`](source/readonly-deep.d.ts) - Create a deeply immutable version of an `object`/`Map`/`Set`/`Array` type. Use [`Readonly<T>`](https://github.com/Microsoft/TypeScript/blob/2961bc3fc0ea1117d4e53bc8e97fa76119bc33e3/src/lib/es5.d.ts#L1415-L1420) if you only need one level deep. - [`LiteralUnion`](source/literal-union.d.ts) - Create a union type by combining primitive types and literal types without sacrificing auto-completion in IDEs for the literal type part of the union. Workaround for [Microsoft/TypeScript#29729](https://github.com/Microsoft/TypeScript/issues/29729). - [`Promisable`](source/promisable.d.ts) - Create a type that represents either the value or the value wrapped in `PromiseLike`. - [`Opaque`](source/opaque.d.ts) - Create an [opaque type](https://codemix.com/opaque-types-in-javascript/). - [`SetOptional`](source/set-optional.d.ts) - Create a type that makes the given keys optional. - [`SetRequired`](source/set-required.d.ts) - Create a type that makes the given keys required. - [`ValueOf`](source/value-of.d.ts) - Create a union of the given object's values, and optionally specify which keys to get the values from. - [`PromiseValue`](source/promise-value.d.ts) - Returns the type that is wrapped inside a `Promise`. - [`AsyncReturnType`](source/async-return-type.d.ts) - Unwrap the return type of a function that returns a `Promise`. - [`ConditionalKeys`](source/conditional-keys.d.ts) - Extract keys from a shape where values extend the given `Condition` type. - [`ConditionalPick`](source/conditional-pick.d.ts) - Like `Pick` except it selects properties from a shape where the values extend the given `Condition` type. - [`ConditionalExcept`](source/conditional-except.d.ts) - Like `Omit` except it removes properties from a shape where the values extend the given `Condition` type. - [`UnionToIntersection`](source/union-to-intersection.d.ts) - Convert a union type to an intersection type. - [`Stringified`](source/stringified.d.ts) - Create a type with the keys of the given type changed to `string` type. - [`FixedLengthArray`](source/fixed-length-array.d.ts) - Create a type that represents an array of the given type and length. - [`IterableElement`](source/iterable-element.d.ts) - Get the element type of an `Iterable`/`AsyncIterable`. For example, an array or a generator. - [`Entry`](source/entry.d.ts) - Create a type that represents the type of an entry of a collection. - [`Entries`](source/entries.d.ts) - Create a type that represents the type of the entries of a collection. - [`SetReturnType`](source/set-return-type.d.ts) - Create a function type with a return type of your choice and the same parameters as the given function type. - [`Asyncify`](source/asyncify.d.ts) - Create an async version of the given function type. ### Template literal types *Note:* These require [TypeScript 4.1 or newer](https://devblogs.microsoft.com/typescript/announcing-typescript-4-1/#template-literal-types). - [`CamelCase`](ts41/camel-case.d.ts) – Convert a string literal to camel-case (`fooBar`). - [`KebabCase`](ts41/kebab-case.d.ts) – Convert a string literal to kebab-case (`foo-bar`). - [`PascalCase`](ts41/pascal-case.d.ts) – Converts a string literal to pascal-case (`FooBar`) - [`SnakeCase`](ts41/snake-case.d.ts) – Convert a string literal to snake-case (`foo_bar`). - [`DelimiterCase`](ts41/delimiter-case.d.ts) – Convert a string literal to a custom string delimiter casing. - [`Get`](ts41/get.d.ts) - Get a deeply-nested property from an object using a key path, like [Lodash's `.get()`](https://lodash.com/docs/latest#get) function. ### Miscellaneous - [`PackageJson`](source/package-json.d.ts) - Type for [npm's `package.json` file](https://docs.npmjs.com/creating-a-package-json-file). - [`TsConfigJson`](source/tsconfig-json.d.ts) - Type for [TypeScript's `tsconfig.json` file](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html) (TypeScript 3.7). ## Declined types *If we decline a type addition, we will make sure to document the better solution here.* - [`Diff` and `Spread`](https://github.com/sindresorhus/type-fest/pull/7) - The PR author didn't provide any real-world use-cases and the PR went stale. If you think this type is useful, provide some real-world use-cases and we might reconsider. - [`Dictionary`](https://github.com/sindresorhus/type-fest/i
