`DpcJson`

The DpcJson type describes the configuration of a database-oriented Persister operating in serialized JSON mode.

{
  mode: "json";
  storeTableName?: string;
  autoLoadIntervalSeconds?: number;
}

	Type	Description
`mode`	`"json"`	The mode to be used for persisting the `Store` to the database, in this case JSON serialization. See the `DpcTabular` type for the alternative tabular mapping mode.
`storeTableName?`	`string`	An optional string which indicates the name of a table in the database which will be used to serialize the `Store` content into. It defaults to `tinybase`.
`autoLoadIntervalSeconds?`	`number`	How often the `Persister` should poll the database for any changes made to it by other clients, defaulting to 1 second.

The only setting is the storeTableName property, which indicates the name of a table in the database which will be used to serialize the Store content into. It defaults to tinybase.

That table in the database will be given two columns: a primary key column called _id, and one called store. The Persister will place a single row in this table with _ in the _id column, and the JSON serialization in the store column, something like:

> SELECT * FROM tinybase;
+-----+-----------------------------------------------------+
| _id | store                                               |
+-----+-----------------------------------------------------+
| _   | [{"pets":{"fido":{"species":"dog"}}},{"open":true}] |
+-----+-----------------------------------------------------+

The 'Dpc' prefix indicates that this type is used within the DatabasePersisterConfig type.

Example

When applied to a database Persister, this DatabasePersisterConfig will load and save a JSON serialization from and to a table called tinybase_json.

const databasePersisterConfig: DatabasePersisterConfig = {
  mode: 'json',
  storeTableName: 'tinybase_json',
};
