NodeJS and pg-promise, insert dynamically from JSON-object

I'm running NodeJS and pg-promise, and are trying to accomplish somethings like:

db.none('INSERT INTO my-table (JSON-object-keys) VALUES ($1)', [JSON-object-values])
    .catch(function(err) {
        console.log('Error on insert into my-table: ' + err);
    });

I have JSON-objects which can look like:

{"column1":"value1", "column2":"value2", "column3":"value3"}
{"column2":"value2", "column3":"value3"}
{"column1":"value1", "column3":"value3"}

I would like to have the INSERTS automatically generated corresponding to what the JSON-object contains.

Is that possible in an elegant way?
