Our marketing partners want to show short, easy to type URLs on the info screen in our vehicles.
Design and implement an URL shortener HTTP service that fulfills the following criteria:
- Provides an HTTP API to:
- Shorten a URL
- Redirect to the long URL from the shortened URL
- Shortened URL requirements:
- The ID of the shortened URL needs to be unique (across past and concurrent requests)
- The ID of the shortened URL should be as short as possible (max. 10 characters long)
For example when your service would run under the domain https://short.io this URL https://www.moia.io/my/ride/123456 should look like the this https://short.io/a2bj3 after being shortened. When calling https://short.io/a2bj3 a user should be redirected to https://www.moia.io/my/ride/123456.
- Any URL can be sent to the REST service which will return a shortened URL.
- The shortened URL has a length of at most 10 characters.
- A shortened URL cannot be duplicated; e.g. two different links won’t provide the same short name.
- Your solution is implemented in Go.
- Persisting the shortened Urls is optional. It is also enough to just store it in-memory.
- We have to be able to run your solution during assessment.
- Authentication or authorization can be ignored here.
- What we look at during the assessment:
- How easy it is to understand and maintain your code.
- How you verify your software, whether by automated tests or otherwise.
- How clean your design and implementation is.
- Document where you think it makes sense and helps us to review your code.
