Sample:
response.rooms.push({
maxPlayers: doc.maxPlayers,
ownderId: doc.ownderId,
roomId: doc.ownderId,
state: doc.state,
type: doc.type,
});
All the parameters share the same name here. However, the doc object has additional parameters that I don't want to relate to rooms. Any suggestions? This is manageable with small objects but becomes tedious with larger ones.
The doc object contains certain parameters that should not be directly mapped to rooms.
It is important to explicitly specify which attributes you want to extract from the doc object. For larger objects, creating a function like buildRoom can help in shaping the output using dot access or destructuring, ultimately streamlining the process.
function buildRoom1(obj: typeof doc) {
const {
maxPlayers,
ownerId,
state,
type,
...
} = doc;
return {
maxPlayers,
ownerId,
roomId: doc.ownerId,
state,
type
};
}
response.rooms.push(buildRoom(doc));
Alternatively:
function pluck<T extends Record<PropertyKey, any>, K extends keyof T>(obj: T, ...fields: K[]) {
return fields.reduce((acc, field) => ({ ...acc, [field]: obj[field] }), {} as Pick<T, K>);
}
const room = pluck(doc, "ownderId", "state", "type", "maxPlayers");
response.rooms.push({ ...doc, roomId: room.ownderId });
Or with an additional level of abstraction:
function buildRoom2(obj: typeof doc) {
const props = pluck(obj, "ownderId", "state", "type", "maxPlayers");
return { ...props, roomId: props.ownderId };
}
response.rooms.push(buildRoom2(doc));
For those who are completely confident that the attributes consistently align, consider implementing the following solution:
data.rooms.push({...document})
