metadata-decorators

DTO decorators with reflect-metadata.

Provides an implementation of a dto-decorators flavor that persists metadata using reflect-metadata; other systems may use this persistence to implement runtime logic that is aware of decorated attributes.

Usage

Decorate a class with METADATA_DECORATORS (or any composition thereof):

1import { METADATA_DECORATORS } from '@hippo-oss/metadata-decorators';
2
3const { IsString } = METADATA_DECORATORS;
4
5class Example {
6    @IsString({
7        optional: true,
8    })
9    name?: string;
10}

At runtime, query the class for schema data:

1import { getSchema } from '@hippo-oss/metadata-decorators'
2
3const schema = getSchema(Example);
