    turtlecoin-wallet-backend

    Provides an interface to the TurtleCoin network, allowing wallet applications to be built.

    • Downloads blocks from the network, either through a traditional daemon, or a blockchain cache for increased speed
    • Processes blocks, decrypting transactions that belong to the user
    • Sends and receives transactions

    Installation

    NPM:

    npm install turtlecoin-wallet-backend --save

    Yarn:

    yarn add turtlecoin-wallet-backend

    Documentation

    You can view the documentation here

    You can see a list of all the other classes on the right side of the screen. Note that you will need to prefix them all with WB. to access them, if you are not using typescript style imports, assuming you imported with const WB = require('turtlecoin-wallet-backend').

    Quick Start

    You can find an example project in the examples folder.

    Javascript

    const WB = require('turtlecoin-wallet-backend');
     
    (async () => {
        const daemon = new WB.Daemon('127.0.0.1', 11898);
        /* OR
        const daemon = new WB.Daemon('blockapi.turtlepay.io', 443);
        */
        
        const wallet = WB.WalletBackend.createWallet(daemon);
     
        console.log('Created wallet');
     
        await wallet.start();
     
        console.log('Started wallet');
     
        wallet.saveWalletToFile('mywallet.wallet', 'hunter2');
     
        /* Make sure to call stop to let the node process exit */
        wallet.stop();
    })().catch(err => {
        console.log('Caught promise rejection: ' + err);
    });

    Typescript

    import { WalletBackend, Daemon, IDaemon } from 'turtlecoin-wallet-backend';
     
    (async () => {
        const daemon: IDaemon = new Daemon('127.0.0.1', 11898);
     
        /* OR
        const daemon: IDaemon = new Daemon('blockapi.turtlepay.io', 443);
        */
     
        const wallet: WalletBackend = WalletBackend.createWallet(daemon);
     
        console.log('Created wallet');
     
        await wallet.start();
     
        console.log('Started wallet');
     
        wallet.saveWalletToFile('mywallet.wallet', 'hunter2');
     
        /* Make sure to call stop to let the node process exit */
        wallet.stop();
    })().catch(err => {
        console.log('Caught promise rejection: ' + err);
    });

    Configuration

    There are a few features which you may wish to configure that are worth mentioning.

    Auto Optimize

    Auto optimization is enabled by default. This makes the wallet automatically send fusion transactions when needed to keep the wallet permanently optimized.

    To enable/disable this feature, use the following code:

    wallet.enableAutoOptimization(false); // disables auto optimization

    Coinbase Transaction Scanning

    By default, coinbase transactions are not scanned. This is due to the majority of people not having solo mined any blocks.

    If you wish to enable coinbase transaction scanning, run this line of code:

    wallet.scanCoinbaseTransactions(true)

    Logging

    By default, the logger is disabled. You can enable it like so:

    wallet.setLogLevel(WB.LogLevel.DEBUG);

    and in typescript:

    wallet.setLogLevel(LogLevel.DEBUG);

    The logger uses console.log, i.e. it outputs to stdout.

    If you want to change this, or want more control over what messages are logged, you can provide a callback for the logger to call.

    wallet.setLoggerCallback((prettyMessage, message, level, categories) => {
        if (categories.includes(WB.LogCategory.SYNC)) {
            console.log(prettyMessage);
        }
    });

    and in typescript:

    wallet.setLoggerCallback((prettyMessage, message, level, categories) => {
        if (categories.includes(LogCategory.SYNC)) {
            console.log(prettyMessage);
        }
    });

    In this example, we only print messages that fall into the SYNC category.

    You can view available categories and log levels in the documentation.

    Contributing

    Building (For Developers)

    git clone https://github.com/turtlecoin/turtlecoin-wallet-backend-js.git

    cd turtlecoin-wallet-backend

    npm install -g yarn (Skip this if you already have yarn installed)

    yarn install

    yarn build

    Generated javascript files will be written to the dist/lib/ folder.

    Running tests

    yarn test - This will run the basic tests

    yarn test-all - This will run all tests, including performance tests.

    Before making a PR

    • Ensure you are editing the TypeScript code, and not the JavaScript code (You should be in the lib/ folder)
    • Ensure you have updated the documentation if necessary - Documentation is generated from inline comments, jsdoc style.
    • Ensure you have rebuilt the documentation, if you have changed it: yarn docs
    • Ensure the tests all still pass: yarn test, or yarn test-all if you have a local daemon running.
    • If adding a feature/fixing a bug, adding a test to verify your fix/feature functions as expected would be great. But don't sweat it.
