How to Build'n'Run src/example.cpp

1. Install dependencies (via apt, homebrew etc.).
2. Clone or download bfx-api-cpp repository.
3. Add key-secret file in bfx-api-cpp/app/doc directory. (or edit example.cpp so that it doesn't use key-secret file)
4. Peek into self-documented <your_project_dir>/app/src/example.cpp.
5. Build example binary

cd <your_project_dir>app/build && cmake .. && make

7. Run example binary from <your_project_dir>app/bin

./example

How to Build'n'Run src/example.cpp in Docker container

1. Clone or download bfx-api-cpp repository.
2. Build docker image

cd <your_project_dir>
docker-compose build

3. Start docker image

docker-compose up &

4. Spawn bash

docker exec -it bfx-cpp-api_dev_1 /bin/sh

5. Add key-secret file in /home/bfx-cpp-api/app/doc directory. (or edit example.cpp so that it doesn't use key-secret file)

cd /home/bfx-cpp-api/app/doc
echo <key> > key-secret
echo <secret> >> key-secret

6. Build example

cd /home/bfx-cpp-api/app/build
cmake ..
make

7. Run example binary

cd /home/bfx-cpp-api/app/bin
./example

Quick interface overview

// Create API client for both authenticated and unauthenticated requests
BfxAPI::BitfinexAPI bfxAPI("accessKey", "secretKey");

// Create API client for just unauthenticated requests
BfxAPI::BitfinexAPI bfxAPI();

// Fetch data
bfxAPI.getTicker("btcusd");

// Check for errors
if (!bfxAPI.hasApiError())
{
    // Get response in string
    cout << bfxAPI.strResponse() << endl;
}
else
{
    // Inspect errors
    cout << bfxAPI.getBfxApiStatusCode() << endl;
    cout << bfxAPI.getCurlStatusCode() << endl;
}
