Retrieves the first entity from the table that matches the given filter, or null
if no entity matches.
const firstUserNamedBob = await first(userTable, {
where: {
name: "Bob"
}
});
Parameter | Description |
---|---|
table
|
The table created by createTable() .
|
filterOrId
| Optional. Can be either a filter or primary id. If given, the item returned will be the first one to match. See filters. |
If no second parameter is supplied, first()
will return the first item in the table.
const firstUser = await first(userTable);
What exactly is meant by the “first” item in the table depends upon the insertion order, so the result is not exactly deterministic. Still, this is sometimes useful for tables that only ever store zero or one entity.
If an id is given as the second parameter, first()
will return either the entity with a matching primary id or null
if no such entity exists.
const aliceUser = await first(userTable, "alice-uuid");
If a filter is provided as the second parameter, first()
returns the first item that matches the filter (or null
if
no item in the table matches the filter).
const firstUserNamedAlice = await first(userTable, {
where: {
name: "Alice"
}
});
