Older versions
|
|
--------------------
|
|
|
|
**Version 4.x.x**
|
|
|
|
As part of the changes in the BigchainDB 2.0 server, some endpoints were
|
|
modified. In order to be consistent with them, the JS driver does not have
|
|
anymore the `pollStatusAndFetchTransaction()` method as there are three
|
|
different ways of posting a transaction:
|
|
|
|
- `commit` using the `postTransaction` or the `postTransactionCommit`: the response will return after the transaction is committed to a block.
|
|
- `sync` using the `postTransactionSync`: the response will return after the transaction is validated.
|
|
- `async` using the `postTransactionAsync`: the response will return immediately and not wait to see if the transaction is valid.
|
|
|
|
By default in the docs we will use the `postTransactionCommit` as is way of
|
|
being sure that the transaction is validated and commited to a block, so
|
|
there will not be any issue if you try to do any other action with the asset immediately.
|
|
|
|
Note: In order to not create breaking changes, both methods `postTransaction` and `postTransactionCommit` are kept although
|
|
they do exactly the same
|
|
|
|
|
|
**Version 3.2.x**
|
|
|
|
For versions below 3.2, a transfer transaction looked like:
|
|
|
|
.. code-block:: js
|
|
|
|
const createTranfer = BigchainDB.Transaction.makeTransferTransaction(
|
|
txCreated,
|
|
metadata, [BigchainDB.Transaction.makeOutput(
|
|
BigchainDB.Transaction.makeEd25519Condition(alice.publicKey))],
|
|
0
|
|
)
|
|
|
|
const signedTransfer = BigchainDB.Transaction.signTransaction(createTranfer,
|
|
keypair.privateKey)
|
|
|
|
|
|
In order to upgrade and do it compatible with the new driver version, this
|
|
transaction should be now:
|
|
|
|
.. code-block:: js
|
|
|
|
const createTranfer = BigchainDB.Transaction.makeTransferTransaction(
|
|
[{ tx: txCreated, output_index: 0 }],
|
|
[BigchainDB.Transaction.makeOutput(
|
|
BigchainDB.Transaction.makeEd25519Condition(alice.publicKey))],
|
|
metaData
|
|
)
|
|
|
|
const signedTransfer = BigchainDB.Transaction.signTransaction(createTranfer,
|
|
keypair.privateKey)
|
|
|
|
|
|
The upgrade allows to create transfer transaction spending outputs that belong
|
|
to different transactions. So for instance is now possible to create a transfer
|
|
transaction spending two outputs from two different create transactions:
|
|
|
|
|
|
.. code-block:: js
|
|
|
|
const createTranfer = BigchainDB.Transaction.makeTransferTransaction(
|
|
[{ tx: txCreated1, output_index: 0 },
|
|
{ tx: txCreated2, output_index: 0}],
|
|
[BigchainDB.Transaction.makeOutput(
|
|
BigchainDB.Transaction.makeEd25519Condition(alice.publicKey))],
|
|
metaData
|
|
)
|
|
|
|
const signedTransfer = BigchainDB.Transaction.signTransaction(createTranfer,
|
|
keypair.privateKey)
|
