-  "readme": "# DTO and Builder Pattern\n\n[Full documentation](https://bendat.github.io/autometa/docs/libraries/dto-builder/intro)\nThis library allows defining DTO classes with decoratated properties.\nYou an then automatically create a new builder class that incrementally\nassigns the value of the DTO, and returns the built result.\n\n:::caution\nThis library requires experimental decorators and a reflect polyfill\nlike [reflect-metadata](https://www.npmjs.com/package/reflect-metadata)\n:::\n\n## Installation\n\n```sh title=npm\n    npm i -D @autometa/dto-builder\n```\n\n```sh title=yarn\n    yarn add -D @autometa/dto-builder\n```\n\n```sh title=pnpm\n    pnpm add -D @autometa/dto-builder\n```\n\n## Use\n\n### Creating a DTO\n\nTo create a DTO, simply create a class which matches the data type your\nrepresenting. Then, decorate its properties with the `@Property` decorator.\n\n```ts\nimport { Property } from \"@autometa/dto-builder\";\n\nexport class UserDto {\n  @Property\n  id: number;\n  @Property\n  name: string;\n  @Property\n  age: number;\n}\n```\n\n### Creating a builder\n\nNow that we have a DTO, we can make a builder for it. Simply pass\nyour DTO class prototype to the `Builder` function. It will return a new\nclass whos interface matches the DTO, but with functions accepting a value\ninstead of raw properties.\n\nThe builder functions are compile-time type safe but do no\nrun time validation.\n\nIf the `class validator` package is installed, the DTO will be validated on build. This can be bypassed by passing `false` to the build method\n\n```ts\nimport { Builder } from \"@autometa/dto-builder\";\nimport { UserDto } from \"./user-dto\";\n\nclass UserBuilder extends Builder(UserDto);\n\nconst userBuilder = new UserBuilder();\nuserBuilder.id(1).name(\"bob\").age(23);\n// methods are type safe\n// -------------\n// error       |\n//             V\nuserBuilder.id(\"1\").name(\"bob\").age(23);\n\n// Bypass\nuserBuilder\n  .id(\"1\" as unknown as number)\n  .name(\"bob\")\n  .age(23);\n```\n\nYou can also pass in an already existing DTO and build it\nfurther.\n\n```ts\nconst cachedUser = new UserDto();\nconst userBuilder = new UserBuilder(cachedUser);\n```\n\n# Default Values\n\nYou can pass a value into the Property decorator to provide a default value.\nThe default value will be injected by the Builder class.\n\n```ts\nimport { DTO } from \"@autometa/dto-builder\";\n\nexport class UserDto {\n  @DTO.value(100)\n  id: number;\n  @DTO.value(\"paul\")\n  name: string;\n  @DTO.value(20)\n  age: number;\n}\n\nconst user = new UserBuilder().build();\n\nconsole.log(user.id === 100); // true\nconsole.log(user.name === \"paul\"); // true\nconsole.log(user.age === 20); // true\n```\n\nFactories can also be used:\n\n```ts\nimport { Property } from \"@autometa/dto-builder\";\n\nexport class UserDto {\n  @DTO.factory(() => Math.random())\n  id: number;\n  @DTO.factory(() => \"paul\")\n  name: string;\n  @DTO.factory(() => 20)\n  age: number;\n}\n```\n\nNote: factories must by synchronous.\n\n## Nesting DTOs\n\nFor complex classes with nested classes or objects it is advisable to use a type\nor interface rather than a Dto type.\n\n```ts\n// prefer not\nclass InnerDto {\n  value: number;\n}\n\nclass OuterDto {\n  @DTO.dto(InnerDto)\n  inner: InnerDto;\n}\n\n// prefer\ninterface Inner {\n  value: number;\n}\n\nclass InnerDto implements Inner {\n  value: number;\n}\n\nclass OuterDto {\n  @DTO.dto(InnerDto)\n  inner: Inner;\n}\n```\n\nTo make a DTO available for nesting, pass its prototype to the Property decorator\nas its default value. Note, this is the prototype, not an instance.\n\n```ts\n\n// prefer\ninterface Inner {\n    value: number\n}\n\nclass InnerDto {\n  @DTO.value(1)\n  value: number;\n}\n\nclass OuterDto {\n  @DTO.value(InnerDto)\n  inner: Inner;\n}\n\nconst Outer = new OuterBuilder().build()\nconsole.log(outer.inner instanceOf InnerDto); // true\nconsole.log(outer.innerr.value === 1); // true\n```\n\nYou can also create a unique dto with default values by calling the static `default`\nmethod on your builder\n\n```ts\nconst Outer = OuterBuilder.default();\n```\n\nFor many tests, valid default values may be all you need on your dto. If\nyou wish to make further edits you can pass the instance to a builder later\n\n```ts\nnew OuterBuilder(Outer).inner(new InnerBuilder().value(1).build());\n```\n\nNote that this will mutate the original dto. You do not need to reassign it or\neven `build` it.\n\n## Dates\n\nThe `date` decorator will create a new date object for that property\nwhen the builder is instantiated. If a unix timestamp or parseable\nstring is passed, it will be used to create the date.\n\n```ts\nimport { DTO } from \"@autometa/dto-builder\";\n\nexport class UserDto {\n  @DTO.date\n  createdAt: Date;\n}\n\n// with unix timestamp\n\nexport class UserDto {\n  @DTO.date(1620000000000)\n  createdAt: Date;\n}\n\n// with string\n\nexport class UserDto {\n  @DTO.date(\"2021-05-02T00:00:00.000Z\")\n  createdAt: Date;\n}\n```\n\n## Interfaces - reducing duplication\n\nIf you define your types initially as interfaces, or generate interfaces from\nvalidation libraries like `zod` and `myzod`, you can reduce duplication by\nextending the `DTO` function with an interface.\n\n```ts\nimport { DTO } from \"@autometa/dto-builder\";\n\ninterface IUser {\n  id: number;\n  name: string;\n  age: number;\n}\n\nexport class UserDto extends DTO<IUser> {}\n\nconst user = new UserBuilder().id(0).name(\"bob\").build();\n```\n\n# DTO From Raw Object\n\nSometimes it's necessary to convert a raw object into a DTO. This can be achieved by\ncalling `fromRaw` on the Builder class, passing it the raw object.\n\n```ts\nconst raw = { Outer: { inner: { value: 1 } } };\nconst dto = OuterBuilder.fromRaw(raw);\n\nexpect(dto).toBeInstanceOf(Outer);\n```\n\n## Interfaces - Anonymous Object Builders\n\nIt might not be desirable to build your object as a class. When not used\nto extend a class, the `DTO` function will return an anonymous object builder,\nwith the same interface as the class builder.\n\n```ts\nimport { Builder } from \"@autometa/dto-builder\";\n\ninterface IUser {\n  id: number;\n  name: string;\n  age: number;\n}\n\nconst UserBuilder = Builder<IUser>();\n```\n\n### Deriving a builder and default values\n\nSince anonymous objects cannot be decorated, they cannot\naccept default values or factories which might change between\ninstantiations.\n\nTo work around this, an anonymous builder is `derivable`. Any values\nassigned to the builder will stay until the builder is built. However\nwhen the `derive` method is called, a new builder will be created,\ncopying the values from the original. If those values are set agin\nin the derived builder, they will not affect the original.\n\n```ts\n\nconst bobBuilder = new UserBuilder().id(1).name(\"bob\").age(23);\n\nconst olderBobBuilder = bobBuilder.derive().age(24);\n```"
