Welcome to the Artist API

This API allows you to search for artists and retrieve information about them. It also saves the result as a CSV file.

Task

Write a Node.js REST API application that handles the following:

• Search for an artist by name based on the following endpoint artist.search, return all the results for this artist.
• Writes the result to a user-supplied CSV filename.
• The CSV file should include the following information (name, mbid, url, image_small, image)

⇒ If no results returned from the artist.search endpoint, retrieve random artist names from a JSON dictionary source file for example:

[‘artistName1’, ‘artistName2’, ‘artistName3’]

Repeat as necessary until you have gathered a list of artists.

Notes

• For the image field in the CSV file, I assumed it referred to the array of images that is returned for each artist.
• For the list of artists, I assumed it referred to a list per artist (search), so the final list used were the ones generated in the tests.
• Just for the review of this code I will upload the .env file in order to avoid any further issue.

Endpoint

The endpoint for the API is:

http://localhost:3000/artist

Query Parameters

You can pass two query parameters: name and filename.

• name: The name of the artist you want to search for. If this parameter is not provided, a random artist will be used.
• filename: The name of the file you want to save the result to. If this parameter is not provided, a default name will be used.

Example

Here is an example URL that searches for the artist "Coldplay" and saves the result to a file named "artists":

http://localhost:3000/artist?name=coldplay&filename=artists

Response

The API will return a JSON object with the following information:

• name: The name of the artist.
• mbid: The MusicBrainz Identifier of the artist.
• url: The URL of the artist's page on Last.fm.
• image_small: The URL of a small image of the artist.
• image: An array of images of different sizes.

CSV file

The result will also be saved as a CSV file in the "files" directory in the project. The file will have the following columns:

• name
• mbid
• url
• image_small
• image
