Setting up Development Environment

Install Node.js

Install Node.js by your favorite method, or use Node Version Manager by following directions at https://github.com/creationix/nvm

Fork and Download Repositories

To develop litecore-node:

cd ~
git clone git@github.com:<yourusername>/litecore-node.git
git clone git@github.com:<yourusername>/litecore-lib.git

To develop litecoin or to compile from source:

git clone git@github.com:<yourusername>/litecoin.git
git fetch origin <branchname>:<branchname>
git checkout <branchname>

Note: See litecoin documentation for building litecoin on your platform.

Install Development Dependencies

For Ubuntu:

sudo apt-get install libzmq3-dev
sudo apt-get install build-essential

Note: Make sure that libzmq-dev is not installed, it should be removed when installing libzmq3-dev.

For Mac OS X:

Install and Symlink

cd litecore-lib
npm install
cd ../litecore-node
npm install

Note: If you get a message about not being able to download litecoin distribution, you'll need to compile litecoind from source, and setup your configuration to use that version.

We now will setup symlinks in litecore-node (repeat this for any other modules you're planning on developing):

cd node_modules
rm -rf litecore-lib
ln -s ~/litecore-lib
rm -rf bitcoind-rpc
ln -s ~/bitcoind-rpc

And if you're compiling or developing litecoin:

cd ../bin
ln -sf ~/litecoin/src/litecoind

Run Tests

If you do not already have mocha installed:

To run all test suites:

cd litecore-node
npm run regtest
npm run test

To run a specific unit test in watch mode:

mocha -w -R spec test/services/bitcoind.unit.js

To run a specific regtest:

mocha -R spec regtest/bitcoind.js

Running a Development Node

To test running the node, you can setup a configuration that will specify development versions of all of the services:

cd ~
mkdir devnode
cd devnode
mkdir node_modules
touch litecore-node.json
touch package.json

Edit litecore-node.json with something similar to:

{
  "network": "livenet",
  "port": 3001,
  "services": [
    "litecoind",
    "web",
    "insight-api",
    "insight-ui",
    "<additional_service>"
  ],
  "servicesConfig": {
    "litecoind": {
      "spawn": {
        "datadir": "/home/<youruser>/.litecoin",
        "exec": "/home/<youruser>/litecoin/src/litecoind"
      }
    }
  }
}

Note: To install services insight-api and insight-ui you'll need to clone the repositories locally.

Setup symlinks for all of the services and dependencies:

cd node_modules
ln -s ~/litecore-lib
ln -s ~/litecore-node
ln -s ~/insight-api
ln -s ~/insight-ui

Make sure that the <datadir>/litecoin.conf has the necessary settings, for example:

server=1
whitelist=127.0.0.1
txindex=1
addressindex=1
timestampindex=1
spentindex=1
zmqpubrawtx=tcp://127.0.0.1:29332
zmqpubhashblock=tcp://127.0.0.1:29332
rpcallowip=127.0.0.1
rpcuser=litecoin
rpcpassword=local321

From within the devnode directory with the configuration file, start the node:

../litecore-node/bin/litecore-node start
