Reading and Writing Data

Read and writing data with Indesely, just like IndexedDB, starts with a transaction. Once a transaction is started, you may read or write data to the database depending on the kind of transaction.

Starting Transactions

Transactions come in three flavors; read-only, read/write, and upgrade. The read-only, read/write transaction are the ones you will use to read and write data during normal operations. Upgrade transactions are only available during migrations, which can also perform most of same functions as read/write transactions.

To start a transaction, you will call either Database.read or Database.change with a list of object store you will interact with. For example:

// Start a read-only transaction.
db.read(['employees'], async (trx) => {
  /* ... */
});
// Start a read/write transaction.
db.change(['employees'], async (trx) => {
  /* ... */
});

Any attempt to interact with any store other than the ones specified will result in an error.

You can learn more about them upgrade transaction by reading about Migrations.
