bson support?

[jinCN]

Is it possible to query raw bson using this library?
Or can this library be helpful to achieve such a goal: searching a big amount of raw data without a whole parsing.

I think Sift should work how you want it to -- do you have a pseudocode example?

I think Sift should work how you want it to -- do you have a pseudocode example?

I can use it like:

let jsData=parse(bson) // maybe bson is 100M and more, costing a lot of cpu
let result=sift(jsData)

But I want:

let result=sift(bson)

To achieve that, sift should have the ability to directly access bson.

Does the compare option help solve your problem? For example:

const compare = (a, b) => {
 if (a instanceof BSONObject && b instanceof BSONObject) {
   reutrn a.value === b.value;
 }
}
sift({ $eq: someBSONObject }, { compare });

I understand it can't be answered by sift, but I ask it here anyway.

I can use it like:

const test = sift({ a:{ $exists: true } }));

test({a:1});

But I want:

const test = sift({ a:{ $exists: true } }));
const bson = BSON.serialize({ a:1 }); // Buffer instance

test(bson);

BSON Buffer is designed to be queriable, it's reasonable to ask to directly query a buffer.

happy to include this functionality in sift if you want to create a PR!

Closing this since it's a bit stale. Happy to re-open if this is still an issue.
