Go API to monitor crypto currency prices, save user preferences to easy investment monitoring and alerts based on thresholds defined by the user
I'm using this API to create an application to monitor my investments in crypto currencies and also to study Go
Feel free to fork and change whatever you need
Still in development
For now, you must run the services manually, I'll provide soon the docker configurations to execute the project in a container.
go run currencies_service/main.go
go run user_info_service/main.go
| Endpoint | Method | Description | Call Example |
|---|---|---|---|
| /crypto/currency/:ids/:convert/:interval | GET | Return a list of prices for each crypto currency in the :ids param | http://localhost:8080/crypto/currency/BTC,ETH/BRL/1h |
| /user/add | POST | Create/Update a new user to monitor his/hers investments | http://localhost:8081/user/add {"name":"Geralt","email":"geralt@ofrivia.com"} |
You must get an APIKey from the Nomics API because the currencies_service uses this API to retrieve crypto data.
You can get your key here: https://p.nomics.com/cryptocurrency-bitcoin-api
After getting your key, you must configure the environment variable NOMICS_API_KEY with the value that you've gotten.
I'll change that later when I add the docker configuration, because that will be set during container creation, but you will need the key anyway
You need to have 2 files in your environment to be able to use DynamoDB to store users information:
~/.aws/credentials
~/.aws/config
To create those files, please follow the AWS documentation: https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-quickstart.html#cli-configure-quickstart-config
Remember that using the AWS Free-Tier you can use up to 25gb of the DynamoDB, which is more than sufficient for this application.
Note: The user that you need to create to obtain the Access Key and Secret Key from AWS must have all the permissions on DynamoDB, to create tables and CRUD data.
