JSONlite

A simple, self-contained, serverless, zero-configuration, json document store.

JSONlite sandboxes the current working directory similar to SQLite. The JSONlite data directory by default is named jsonlite.data and each json document is validated and saved pretty printed as a uuid.

Requirements

bash
uuidgen
python -m json.tool

Alternatively, install yajl for json_reformat or jq to get a significant performance improvement setting documents.

json_reformat is the fastest of the three by far. jq comes in second and python -m json.tool is the slowest. If possible, avoid using python -m json.tool.

Benchmark tests/set_1k.bash:

# MacBook Pro 16" M1 Max
json_reformat: 6s
jq: 19s
python -m json.tool: 28s

Installation

git clone https://github.com/nodesocket/jsonlite.git
ln -s "$PWD"/jsonlite/jsonlite.bash /usr/local/bin/jsonlite

or grab the latest release source code.

Configuration

You may optionally set the path to the data directory. It defaults to $PWD/jsonlite.data but can manually be set with the JSONLITE_DATA_DIR environment variable.

# default
export JSONLITE_DATA_DIR="$PWD"/jsonlite.data

# manually set the data directory
export JSONLITE_DATA_DIR=/tmp/jsonlite.data

Versioning

For transparency and insight into the release cycle, and for striving to maintain backward compatibility, JSONlite will be maintained under the semantic versioning guidelines.

Releases will be numbered with the follow format:

<major>.<minor>.<patch>

And constructed with the following guidelines:

Breaking backward compatibility bumps the major (and resets the minor and patch)
New additions without breaking backward compatibility bumps the minor (and resets the patch)
Bug fixes and misc changes bumps the patch
