Blog API

This is a Node.js Express API that provides endpoints for fetching blog statistics and performing blog searches. It uses memoization to optimize certain operations.

Installation

Clone this repository to your local machine.
Run npm install to install the required dependencies.

Usage

Fetch Blog Statistics

To fetch blog statistics, make a GET request to /api/blog-stats.

Example Request:

GET /api/blog-stats

Example Response:

{
  "totalNumberOfBlogs": 10,
  "longestTitle": "The Longest Blog Title Ever",
  "numberOfBlogsWithPrivacyInTitle": 3,
  "numberOfUniqueTitles": 8,
  "uniqueBlogTitles": ["Blog Title 1", "Blog Title 2", ...]
}

Perform Blog Search

To perform a blog search, make a GET request to /api/blog-search with a query parameter.

Example Request:

GET /api/blog-search?query=privacy

Example Response:

{
  "results": [
    {
      "id": 1,
      "image_url": "https://picsum.photos/200/300",
      "title": "Blog Title 1",
    },
    {
      "id": 2,
      "image_url": "https://picsum.photos/200/300",
      "title": "Blog Title 2",
    },
    ...
  ]
}

If the query parameter is missing, a 400 Bad Request response will be returned.

Memoization

This API uses memoization to optimize the following operations:

Blog statistics calculation using the memoizedFetchAndAnalyzeBlogStats function
Blog search using the memoizedPerformBlogSearch function

Memoization caches the results of these operations to improve performance.

Running the Server

To run the server,run the following command:

node app.js

The server will be running on port 8000.
