Bravo Challenge

[English | Portuguese]

Build an API, which responds to JSON, for currency conversion. It must have a backing currency (USD) and make conversions between different currencies with real and live values.

The API must convert between the following currencies:

• USD
• BRL
• EUR
• BTC
• ETH

Other coins could be added as usage.

Ex: USD to BRL, USD to BTC, ETH to BRL, etc...

The request must receive as parameters: The source currency, the amount to be converted and the final currency.

Ex: ?from=BTC&to=EUR&amount=123.45

Also build an endpoint to add and remove API supported currencies using HTTP verbs.

The API must support conversion between FIAT, crypto and fictitious. Example: BRL->HURB, HURB->ETH

"Currency is the means by which monetary transactions are effected." (Wikipedia, 2021).

Therefore, it is possible to imagine that new coins come into existence or cease to exist, it is also possible to imagine fictitious coins such as Dungeons & Dragons coins being used in these transactions, such as how much is a Gold Piece (Dungeons & Dragons) in Real or how much is the GTA$1 in Real.

Let's consider the PSN quote where GTA$1,250,000.00 cost R$83.50 we clearly have a relationship between the currencies, so it is possible to create a quote. (Playstation Store, 2021).

You can use any programming language for the challenge. Below is the list of languages ​​that we here at Hurb have more affinity:

• JavaScript (NodeJS)
• Python
• Go
• Ruby
• C++
• PHP

Requirements

• Fork this challenge and create your project (or workspace) using your version of that repository, as soon as you finish the challenge, submit a pull request.
  • If you have any reason not to submit a pull request, create a private repository on Github, do every challenge on the main branch and don't forget to fill in the pull-request.txt file. As soon as you finish your development, add the user automator-hurb to your repository as a contributor and make it available for at least 30 days. Do not add the automator-hurb until development is complete.
  • If you have any problem creating the private repository, at the end of the challenge fill in the file called pull-request.txt, compress the project folder - including the .git folder - and send it to us by email.
• The code needs to run on macOS or Ubuntu (preferably as a Docker container)
• To run your code, all you need to do is run the following commands:
  • git clone \$your-fork
  • cd \$your-fork
  • command to install dependencies
  • command to run the application
• The API can be written with or without the help of frameworks
  • If you choose to use a framework that results in boilerplate code, mark in the README which piece of code was written by you. The more code you make, the more content we will have to rate.
• The API needs to support a volume of 1000 requests per second in a stress test.
• The API needs to include real and current quotes through integration with public currency quote APIs

Evaluation criteria

• Organization of code: Separation of modules, view and model, back-end and front-end
• Clarity: Does the README explain briefly what the problem is and how can I run the application?
• Assertiveness: Is the application doing what is expected? If something is missing, does the README explain why?
• Code readability (including comments)
• Security: Are there any clear vulnerabilities?
• Test coverage (We don't expect full coverage)
• History of commits (structure and quality)
• UX: Is the interface user-friendly and self-explanatory? Is the API intuitive?
• Technical choices: Is the choice of libraries, database, architecture, etc. the best choice for the application?

Doubts

Any questions you may have, check the issues to see if someone hasn't already and if you can't find your answer, open one yourself. new issue!

Godspeed! ;)
