Custom strategies

A strategy is a function that returns an object in the following structure

{
	strategy: function (config, value, parent, key) {
		// ...apply strategy
		return value; 
	}
}

Example

let addHardCodedProps = () => {
	return {
		prop1: 1,
		prop2: 1,
		strategy: function (config, value) {
			return {
				...value,
				prop1: config.prop1,
				prop2: config.prop2,
			}
		}
	}
}

// Usage

const MySchema = new schema.Entity('myschema', {}, {
	processStrategy: strategies(
		renameKeys({
			server_id: 'id', // names 'server_id' to 'id'
		}),
		addHardCodedProps(),
    )
});
