Outputs

addOutput(options)

Get some or all outputs on the network. options has the following structure:

{
  // data requests
  type?: OutputType[]

  // related data retrieval
  transaction?: boolean

  range?: {
    from: number
    to?: number
  }
}

Data requests:

• type sets the type of the output. Output type has the following options: 'CoinOutput' | 'ContractOutput' | 'ChangeOutput' | 'VariableOutput' | 'ContractCreated'. Leave it undefined to subscribe to all outputs.

Enabling the transaction flag will cause the processor to retrieve transactions where the selected outputs have occurred. The data will be added to the appropriate iterables within the block data. You can also call augmentBlock() from @subsquid/fuel-objects on the block data to populate the convenience reference fields like output.transaction.

Note that receipts can also be requested by the other FuelDataSource methods as related data.

Selection of the exact fields to be retrieved for each transaction and the optional related data items is done with the setFields() method documented on the Field selection page.

Examples

Request all outputs with ChangeOutput type and include transactions:

processor
  .addOutput({
    type: ["ChangeOutput"],
    transaction: true,
  })
  .build();
