Send bitcoins to SilentPayment static payment codes, in pure typescript.
npm i "github:BlueWallet/SilentPayments" --save
Library is implemented in pure typescript without js-compiled version committed - you might need to configure javascript build on your side.
For example, to use it in jest tests:
package.json:
"jest": {
"transform": {
"^.+\\.(ts|tsx)$": "ts-jest"
},
"transformIgnorePatterns": [
"node_modules/(?!((jest-)?react-native(-.*)?|@react-native(-community)?)|silent-payments/)"
],You must provide UTXOs and targets (which might or might not include SilentPayment codes):
createTransaction(utxos: UTXO[], targets: Target[]): Target[]Finally:
const sp = new SilentPayment();
const targets = sp.createTransaction(
[

),Library will unwrap sp1... codes into correct receivers address. You must provide correct UTXO types to the library, and you must use the same UTXOs
in an actual transaction you create. Library will not do coin selection for you.
