Table.bulkGet()

Since v3.0.0-alpha.8

Syntax

db.table.bulkGet(keys)

Parameters

keys	Array of primary keys of the objects to retrieve

Return Value

Promise

Remarks

Make a request with an array of keys and retrieve a Promise of an array of results. The resulting array will always have the same length as the given array of keys. Every position in the given key array will correspond to the same position in the array of results.

undefined will be returned for those keys that do not exist in the database.

Example

// Define DB
const db = new Dexie('foobardb');
db.version(1).stores({
  friends: 'id'
});

async function test() {
  // Add two friends:
  await db.friends.bulkAdd([{
    id: 1,
    name: "Foo"
  }, {
    id: 2,
    name: "Bar"
  }]);
  
  // Call bulkGet() to lookup values from given keys in the order of the requested array:
  const [foo, nonExisting, bar] = await db.friends.bulkGet([1, 777, 2]);
  console.assert (foo.name === "Foo");
  console.assert (bar.name === "Bar");
  console.assert (nonExisting === undefined);
}

test().then(()=>{
  console.log("success");
}).catch(error => {
  console.error(error);
});
