# 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
```bash
nvm install v4
```
## Fork and Download Repositories
To develop bitcore-node:
```bash
cd ~
git clone git@github.com:<yourusername>/bitcore-node.git
git clone git@github.com:<yourusername>/bitcore-lib.git
```
To develop bitcoin or to compile from source:
```bash
git clone git@github.com:<yourusername>/bitcoin.git
git fetch origin <branchname>:<branchname>
git checkout <branchname>
```
**Note**: See bitcoin documentation for building bitcoin on your platform.
## Install ZeroMQ Development Dependency
For Ubuntu:
```bash
sudo apt-get install libzmq-dev
```
For Mac OS X:
```bash
brew install zeromq
```
## Install and Symlink
```bash
cd bitcore-lib
npm install
cd ../bitcore-node
npm install
```
**Note**: If you get a message about not being able to download bitcoin distribution, you'll need to compile bitcoind from source, and setup your configuration to use that version.
We now will setup symlinks in `bitcore-node` *(repeat this for any other modules you're planning on developing)*:
```bash
cd node_modules
rm -rf bitcore-lib
ln -s ~/bitcore-lib
rm -rf bitcoind-rpc
ln -s ~/bitcoind-rpc
```
And if you're compiling or developing bitcoin:
```bash
cd ../bin
ln -sf ~/bitcoin/src/bitcoind
```
## Run Tests
If you do not already have mocha installed:
```bash
npm install mocha -g
```
To run all test suites:
```bash
cd bitcore-node
npm run regtest
npm run test
```
To run a specific unit test in watch mode:
```bash
mocha -w -R spec test/services/bitcoind.unit.js
```
To run a specific regtest:
```bash
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:
```bash
cd ~
mkdir devnode
cd devnode
mkdir node_modules
touch bitcore-node.json
touch package.json
```
Edit `bitcore-node.json` with something similar to:
```json
{
"network": "livenet",
"port": 3001,
"services": [
"bitcoind",
"web",
"insight-api",
"insight-ui"
],
"servicesConfig": {
"bitcoind": {
"spawn": {
"datadir": "/home/<youruser>/.bitcoin",
"exec": "/home/<youruser>/bitcoin/src/bitcoind"
}
}
}
}
```
Setup symlinks for all of the services and dependencies:
```bash
cd node_modules
ln -s ~/bitcore-lib
ln -s ~/bitcore-node
ln -s ~/insight-api
ln -s ~/insight-ui
```
Make sure that the `<datadir>/bitcoin.conf` has the necessary settings, for example:
```
server=1
whitelist=127.0.0.1
txindex=1
addressindex=1
timestampindex=1
spentindex=1
zmqpubrawtx=tcp://127.0.0.1:28332
zmqpubhashblock=tcp://127.0.0.1:28332
rpcallowip=127.0.0.1
rpcuser=bitcoin
rpcpassword=local321
```
From within the `devnode` directory with the configuration file, start the node:
```bash
../bitcore-node/bin/bitcore-node start
```

# Development & Testing
To run all of the JavaScript tests:
```bash
npm run test
```
If you do not already have mocha installed:
```bash
npm install mocha -g
```
To run the regression tests:
```bash
mocha -R spec regtest/bitcoind.js
```
To be able to debug bitcoind you'll need to have `gdb` and `node` compiled for debugging with gdb using `--gdb` (sometimes called node_g), and you can then run:
```bash
$ gdb --args node examples/node.js
```
To run mocha from within gdb (notice `_mocha` and not `mocha` so that the tests run in the same process):
```bash
$ gdb --args node /path/to/_mocha -R spec integration/regtest.js
```
To run the benchmarks:
```bash
$ cd benchmarks
$ node index.js
```
