Challenge: Text Summarizer Using OpenAI

Problem statement

Text summarization generates a shortened version of a text document that captures the key points and conveys the essential meaning. It condenses lengthy pieces of text, such as articles, research papers, or emails, into a more digestible format while aiming to preserve the original content's core message. In this challenge, there will be a long piece of text that needs to be summarized using OpenAI.

Below are the functions that needs to be implemented in order to finish the challenge. A code editor is provided after the problem statement to complete the coding challenge. Make sure all the points are implemented. After the coding challenge, there is a solution provided in the next lesson.

Requirements

• Implement the fetchSummary() function in the utils.js file. Below are the requirements:

  • The function will accept one parameter: text which needs to be read from the file data.txt.

  • Use OpenAI and a write a suitable prompt to generate the summarized content.

• Implement the readData() function in utils.js file. Below are the requirements:

  • Read the text data from the file data.txt and return the data. Use the fs module to read the file data.

• Implement the API route to get the summary in index.js file. Below are the requirements:

  • An endpoint /get-summary is already created and please do not update the endpoint.

  • Call the fetchSummary() function and make sure error-handling is implemented properly.

  • In case of any error, return an object in the response containing error key and the error message as its value. Also, send the status code as 400.

You can directly access the variable openai_api_key to access your OpenAI key that was set up earlier.
