Simple Nodejs 8 application to look crypto currencies in real time through the terminal using the Bittrex api.
- Nodejs 8+ installed
- Bittrex API key and secret(NEVER put it in your code and commit, instead use environments variables locally)
You'll need to set the api key and secret as environment variable. To know how to generate API keys, take a look on the documentation.
BE AWARE: To use this API you just need the API keys to have READ permissions, It's NOT recommended giving the api keys Sell/Trade permission(at least not using this project).
By default, the script looks the market "USDT-BTC". To run just do:
npm installAPI_KEY=YOUR_API_SECRET_KEY_HERE API_SECRET=YOUR_API_SECRET_KEY_HERE npm start
If you want to look at a different market, you need to set 2 environment variables: BASE_COIN and COIN. Here is an example looking the "BTC-ETH" market:
API_KEY=YOUR_API_SECRET_KEY_HERE API_SECRET=YOUR_API_SECRET_KEY_HERE BASE_COIN=BTC COIN=ETH npm start
Whenever you start running the script it'll create a folder logs and a file named as 'YOUR_BASE_COIN-YOUR_COIN' where you can check easily the whole logs.
the console will also show something like:

If you just try to run npm start, you might notice the following error:
TypeError: Cannot read property 'sigBytes' of undefined
It happens because you tried to run the script without the API_KEY and API_SECRET setup. The library(node-bittrex-api) we're using does not allow starting connections without the api key and secret.
