TypeScript from JSON Schema\n\nThis is a TypeScript definitions that can automatically generate\nTypeScript types given JSON Schema definitions **without** the\nneed of any code generator.\n\nThe caveat is that the JSON Schema must be declared using string\nliterals instead of generic strings, this is achieved by declaring the\nobjects `as const`.\n\nThe associated helper files will aid that task with some constants\nand functions that returns properly typed constructions.\n\n## Install\n\n```sh\nyarn add @profusion/json-schema-to-typescript-definitions\n```\n\nIf you don't use our `commonSchemas` or `schemaHelpers`, you can\nuse it as a `--dev` dependency since the TypeScript checks are\ndone only in compile time.\n\n## Usage\n\n```ts\nimport type { TypeFromJSONSchema } from '@profusion/json-schema-to-typescript-definitions';\n\ntype MyObject = TypeFromJSONSchema\u003c{\n  type: 'object';\n  properties: {\n    a: { type: 'boolean' };\n  };\n  additionalProperties: false;\n}\u003e;\nconst o: MyObject = { a: true };\n```\n\nOne can also use the function helpers to get properly typed objects:\n\n```ts\nimport { commonSchemas, schemaHelpers } from '@profusion/json-schema-to-typescript-definitions';\n\n// declares an actual schema object, you can use with Ajv and others\nconst schema = schemaHelpers.object({\n  properties: {\n    a: commonSchemas.boolean,\n  },\n});\nconst o: TypeFromJSONSchema\u003ctypeof schema\u003e = { a: true };\n```\n\n## Similar Packages\n\nThis package is similar to\n[json-schema-to-typescript](https://www.npmjs.com/package/json-schema-to-typescript),\nhowever that one uses a code-generator that can work out JSON files.\n\nThis package requires `as const` so strings are kept as literals, but\nrequires no code generation. If you define your JSON schemas using\nTypeScript, then you can avoid that code generation burden.\n\n## License\n\nOpen source - [MIT](https://opensource.org/licenses/MIT).\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fprofusion%2Fjson-schema-to-typescript-definitions","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fprofusion%2Fjson-schema-to-typescript-definitions","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fprofusion%2Fjson-schema-to-typescript-definitions/lists"}
