I have been utilizing the automapper-ts with typescript plugin for automatic mapping. Check it out here
While it works smoothly for simple objects, I encountered issues when dealing with complex ones like: Record<string, any> or Map<string, AnotherObject>.
- Here is an example involving
Map<string, SampleItem>:
export class SampleItem {
type: string;
name: string;
example?: unknown;
constructor(data?: SampleItem) {
Object.assign(this, data);
}
}
class Entity {
@AutoMap(() => SampleItem)
sample: Map<string, SampleItem>;
@AutoMap(() => Object)
details: Record<string, any>;
}
This presents a test scenario comparing both situations:
The issue arises from the following payload:
{
sample: {
sampleOne: {
name: 'sample name',
type: SampleTypes.STRING,
example: 'sample example',
} as SampleItem,
},
description: 'description'
}
- Another complication occurred when integrating a complex object with the
detailsfield:
{
description: { des: 'description' } as Record<string, any>,
}
Original error: Error: Mapping is not found for function String() { [native code] } and function String() { [native code] }
