bson-transform
Transform BSON to JavaScript Native Object.
node:stream/Transform and node:stream/web/TransformStream.
Example
import * as fs from "node:fs"
import * as path from "node:path";
import {BsonTransform} from "bson-transform";
const bsonReadStream = fs.createReadStream(path.resolve(__dirname, "archive.bson"));
const bsonTransform = new BsonTransform();
bsonReadStream.pipe(bsonTransform).on("data", (doc) => {
// do something
});If you want to only take each document by Raw BSON Buffer, turn off ObjectMode.
import * as fs from "node:fs"
import * as path from "node:path";
import * as bson from "bson";
import {BsonTransform} from "bson-transform";
const bsonReadStream = fs.createReadStream(path.resolve(__dirname, "archive.bson"));
// if passed `ObjectMode: false` option, you can take BSON Bynary Buffer of each documents.
const bsonTransform = new BsonTransform({ObjectMode: false});
bsonReadStream.pipe(bsonTransform).on("data", (documentBuffer) => {
// deserializable.
const doc = bson.deserialize(documentBuffer);
// ... and do something
});
