    json_

    Build Status npm version

    Converts camelCase JavaScript objects to JSON snake_case and vise versa. This is a direct replacement for the built-in JSON object. In fact, this simply wraps the built-in JSON object. Very handy when your back_end APIs are not build using Node.js. It also supports converting a fetch response stream into a camelCased object.

    First, get the package

    Install json_ and include it in your build.

    npm install json_ --save

    Then import it like this.

    import JSON_ from 'json_';

    Example

    const example = {
        firstName: "John",
        lastName: "Doe",
        isbn10: "1234567890"
    };
     
    console.log(JSON_.stringify(example));
    // {"first_name":"John","last_name":"Doe", "isbn_10": "1234567890"}

    And vise versa.

    import JSON_ from 'json_';
    const str = '{"ultimate_answer": 42}';
     
    console.log(JSON_.parse(str));
    // {ultimateAnswer: 42}

    Using with fetch

    You can use json_ directly with the JavaScript fetch API to convert the Response into an Object with snakeCase.

    Let's say you have a function that returns snake_case weather data, something like this.

    const fetchWeather = zip => (
      fetch(`${weatherUrl}?zip=${zip}`)
        .then(res => res.json())
    );
     
    const data = await fetchWeather('10285');
    console.log(data);
    // {current_temp: 85, reporting_station: 'New York, NY'}

    You can easily convert the resolved object to camelCase by replacing the call to Response.json() to a call to JSON_.parse(Response), like this.

    import JSON_ from 'json_';
     
    const fetchWeather = zip => (
      fetch(`${weatherUrl}?zip=${zip}`)
        .then(JSON_.parse)
    );
     
    const data = await fetchWeather('10285');
    console.log(data);
    // {currentTemp: 85, reportingStation: 'New York, NY'}
