Parameters

sheetSlug - string - (required)

The sheetSlug indicates the slug name of the sheet you want to monitor.

Use the fieldFilters parameter to select specific fields to monitor. Without any specified fieldFilters, the plugin will automatically monitor all castable fields, including strings, numbers, booleans, and dates.

options.chunkSize - default: "10_000" - number

The chunkSize parameter allows you to specify the quantity of records to in each chunk.

options.parallel - default: "1" - number

The parallel parameter allows you to specify the number of chunks to process in parallel.

Usage

The autocast plugin will listen for the commit:created event and cast strings, numbers, booleans, and dates to the appropriate Blueprint type. Note that the recordHook and bulkRecordHook plugins listen for the same event type. Plugins will fire in the order they are placed in the listener.

Strings

Numbers and booleans are transformed from strings to their respective types (i.e., '1' to 1, "true" to true).

Numbers

String numbers (i.e '1'), string decimals (i.e '1.1'), and string numbers with commas (i.e '1,000') are interpreted as numbers.

Booleans

'1', 'yes', 'true', 'on', 't', 'y', and 1 are interpreted as truthy values.

'-1', '0', 'no', 'false', 'off', 'f', 'n', 0, -1 are interpreted as falsy values.

Dates

Date strings and numbers are cast to UTC strings. For example, YYYY-MM-DD... formats are treated as ISO 8601 dates (UTC), whereas other formats are considered local time and converted to UTC:

• '2023-08-16' => 'Wed, 16 Aug 2023 00:00:00 GMT'
• '08-16-2023' => 'Wed, 16 Aug 2023 00:00:00 GMT'
• '08/16/2023' => 'Wed, 16 Aug 2023 00:00:00 GMT'
• 'Aug 16, 2023' => 'Wed, 16 Aug 2023 00:00:00 GMT'
• 'August 16, 2023' => 'Wed, 16 Aug 2023 00:00:00 GMT'
• '2023-08-16T00:00:00.000Z' => 'Wed, 16 Aug 2023 00:00:00 GMT'
• 1692144000000 => 'Wed, 16 Aug 2023 00:00:00 GMT'
