jsonism 1.0.5

A simple JSON schema checker

Python JSON Checker

A super-simple library for validating json against a schema.

Install from pip

pip install jsonism

Why use Jsonism?

Jsonism is a great alternative to jsonschema when you just want to do some simple validation of JSON without your code getting horrendously complicated.

It's quick to set up a basic schema checker.

Example usage

Import the checker

from jsonism.checker import validate

Basic flat objects

schema = {
    "Bob": str,
    "Lucy": int,
    "Bert": bool
}
input = {
    "Bob": "Is Bob",
    "Lucy": 13,
    "Bert": True
}
validate(input, schema)

Lists

input = ["Bob", "Alice", "John"]
schema = [str]
validate(input, schema)

Other stuff

input = {"Usernames": [{"username": "Bob", "age": 23}, {"username": "Bill", "age": 98}]}
schema = {"Usernames": [{"username": str, "age": int}]}
validate(input, schema)

But it doesn't have feature x!

Well, I did say it was simple. I plan on allowing optional value validation in a future version. It will always support the very simple initialisation shown above. If you have a burning desire to add a feature, please either post an issue or make a pull request at https://github.com/bmcollier/jsonism.
