# srsly: Modern high-performance serialization utilities for Python

This package bundles some of the best Python serialization libraries into one
standalone package, with a high-level API that makes it easy to write code
that's correct across platforms and Pythons. This allows us to provide all the
serialization utilities we need in a single binary wheel.

## Motivation

Serialization is hard, especially across Python versions and multiple platforms.
After dealing with many subtle bugs over the years (encodings, locales, large
files) our libraries like [spaCy](https://github.com/explosion/spaCy) and
[Prodigy](https://prodi.gy) have steadily grown a number of utility functions to
wrap the multiple serialization formats we need to support (especially `json`,
`msgpack` and `pickle`). These wrapping functions ended up duplicated across our
codebases, so we wanted to put them in one place.

At the same time, we noticed that having a lot of small dependencies was making
maintenance harder, and making installation slower. To solve this, we've made
`srsly` standalone, by including the component packages directly within it. This
way we can provide all the serialization utilities we need in a single binary
wheel.

`srsly` currently includes forks of the following packages:

-   [`ujson`](https://github.com/esnme/ultrajson)
-   [`msgpack`](https://github.com/msgpack/msgpack-python)
-   [`msgpack-numpy`](https://github.com/lebedov/msgpack-numpy)
-   [`cloudpickle`](https://github.com/cloudpipe/cloudpickle)

## Installation

`srsly` can be installed from pip:

```bash
pip install srsly
```

Or from conda via conda-forge:

```bash
conda install -c conda-forge srsly
```

Alternatively, you can also compile the library from source. You'll need to make
sure that you have a development environment consisting of a Python distribution
including header files, a compiler (XCode command-line tools on macOS / OS X or
Visual C++ build tools on Windows), pip, virtualenv and git installed.

```bash
pip install -r requirements.txt  # install development dependencies
python setup.py build_ext --inplace  # compile the library
```

## API

### JSON

> 📦 The underlying module is exposed via `srsly.ujson`. However, we normally
> interact with it via the utility functions only.

#### <kbd>function</kbd> `srsly.json_dumps`

Serialize an object to a JSON string. Takes care of Python 2/3 compatibility and
falls back to `json` if `sort_keys=True` is used (until it's fixed in `ujson`).

```python
data = {"foo": "bar", "baz": 123}
json_string = srsly.json_dumps(data)
```

| Argument    | Type    | Description                                            |
