Installation

• npm install @mmkal/jsonata

Quick start

Presumably you are using @mmkal/jsonata rather than the upstream jsonata because you want the synchronous API. Here's how you use it:

In Node.js:

const jsonata = require('@mmkal/jsonata/sync');

const data = {
    example: [
        {value: 4},
        {value: 7},
        {value: 13}
    ]
};

(async () => {
    const expression = jsonata('$sum(example.value)');
    const result = pression.evaluate(data);  // returns 24
})()
