Blockchain Contract Action Methods
Each blockchain contract function has some additional functionality you can find very useful
action.getRawTransaction(params, ?options)
Construct raw transaction for an action
1
const faucetContract = eoslime.Contract.fromFile(FAUCET_ABI_PATH, faucetAccount.name, faucetAccount);
2
3
const rawFunctionTx = await faucetContract.actions.produce.
4
getRawTransaction([myAccount.name, '100.0000 TKNS']);

The options one can provide here are the same as the ones for the contract actions
1
const faucetContract = eoslime.Contract.fromFile(FAUCET_ABI_PATH, faucetAccount.name, faucetAccount);
2
3
const rawFunctionTx = await faucetContract.actions.produce.
4
getRawTransaction([myAccount.name, '100.0000 TKNS'], { unique: true });

action.sign(params, ?options)
Sign action and return a ready-to-broadcast transaction
1
const faucetContract = eoslime.Contract.fromFile(FAUCET_ABI_PATH, faucetAccount.name, faucetAccount);
2
3
const signedFunctionTx = await faucetContract.actions.
4
produce.sign([myAccount.name, '100.0000 TKNS']);

Events
processed
You can process some logic every time a contract function is broadcasted to the chain
1
const faucetContract = eoslime.Contract.fromFile(FAUCET_ABI_PATH, faucetAccount.name, faucetAccount);
2
3
faucetContract.produce.on('processed', (txReceipt) =>
4
{
5
// do some custom logic
6
}
7
);
