insert

• lands.insert(<object>) ⇒ promise
• lands.insert(<object>, <callback>)

Use: Insert an item into a table.

Simplest case, just supply the item, everything else defaults.

lands
    .insert({ name: 'China' })
    .then(function(resp) {
        console.log(resp);
    });

Note, your hash key and/or range key must be specified on the object you are inserting or it will fail.

In other words, if your hash key is name and you try to insert any object without a name key, you will get an error because the key must appear in the object so it can be properly inserted and indexed by DynamoDB.

lands
    .insert({ population: 1375000000 })
    .then(function(resp) {
        console.log(resp);
    })
    .catch(function(err) {
        // Will get an error here about not including the hashKey!
    });

Can optionally supply a traditional node callback

lands.insert({ name: 'China' }, function(err, resp) {
    console.log(resp);
});
