A library for converting between BSON and JSON.

Project Description
Info:See github for the latest source.
Author:Shane Harvey <shane.harvey@mongodb.com>

About

A fast BSON to MongoDB Extended JSON converter for Python that uses libbson.

Installation

python-bsonjs can be installed with pip:

$ python -m pip install python-bsonjs

Examples

>>> import bsonjs
>>> bson_bytes = bsonjs.loads('{"hello": "world"}')
>>> bson_bytes
'\x16\x00\x00\x00\x02hello\x00\x06\x00\x00\x00world\x00\x00'
>>> bsonjs.dumps(bson_bytes)
'{ "hello" : "world" }'

Using bsonjs with pymongo to insert a RawBSONDocument.

>>> import bsonjs
>>> from pymongo import MongoClient
>>> from bson.raw_bson import RawBSONDocument
>>> client = MongoClient("localhost", 27017, document_class=RawBSONDocument)
>>> db = client.test
>>> bson_bytes = bsonjs.loads('{"_id": 1, "x": 2}')
>>> bson_bytes
'\x15\x00\x00\x00\x10_id\x00\x01\x00\x00\x00\x10x\x00\x02\x00\x00\x00\x00'
>>> result = db.test.insert_one(RawBSONDocument(bson_bytes))
>>> result.inserted_id  # NOTE: inserted_id is None
>>> result.acknowledged
True
>>> raw_doc = db.test.find_one({'x': 2})
>>> raw_doc.raw == bson_bytes
True
>>> bsonjs.dumps(raw_doc.raw)
'{ "_id" : 1, "x" : 2 }'

Speed

bsonjs is roughly 10-15x faster than PyMongo’s json_util at decoding BSON to JSON and encoding JSON to BSON. See benchmark.py:

$ python benchmark.py
Timing: bsonjs.dumps(b)
10000 loops, best of 3: 0.110911846161
Timing: json_util.dumps(bson.BSON(b).decode())
10000 loops, best of 3: 1.46571397781
bsonjs is 13.22x faster than json_util

Timing: bsonjs.loads(j)
10000 loops, best of 3: 0.0628039836884
Timing: bson.BSON().encode(json_util.loads(j))
10000 loops, best of 3: 0.683200120926
bsonjs is 11.72x faster than json_util

Installing From Source

python-bsonjs supports CPython 2.6, 2.7, and 3.3+.

Compiler

You must build python-bsonjs separately for each version of Python. On Windows this means you must use the same C compiler your Python version was built with.

Source

Note that this repository contains a git submodule. You must initialize the submodule by using:

$ git clone --recursive https://github.com/mongodb-labs/python-bsonjs.git

Or, if your version of git does not have clone --recursive:

$ git clone https://github.com/mongodb-labs/python-bsonjs.git
$ cd python-bsonjs
$ git submodule update --init --recursive

Install

Once you have the source properly downloaded, build and install the package:

$ python setup.py install

Test

To run the test suite:

$ python setup.py test
