# Doctors.com Backend

Overview

Doctors.com backend provides API endpoints and functionalities to manage hospital and patient-related operations. This backend supports features like uploading patient reports, submitting reports to specific hospitals, and searching for hospitals from a database.

Features

• User Authentication: Secure authentication using JSON Web Tokens (JWT).
• File Uploads: Upload patient reports using Multer middleware, with optional Cloudinary integration for storing files.
• Hospital Search: Search for hospitals from the database using efficient queries.
• Report Submission: Submit patient reports to a specific hospital.
• Data Security: Passwords are hashed using bcrypt.
• Pagination: Paginate results for hospital listings and search queries to improve performance and user experience.
• MongoDB Pipelines:
  • Fetching all hospitals with aggregation pipelines to include relevant data and support filtering/sorting.
  • Submitting reports by aggregating and validating hospital and patient data.
  • Searching for a specific hospital by its name using optimized text indexes or regex patterns.

Database

The backend uses MongoDB as the database, and Mongoose is used as the ODM for defining schemas and querying the database.

Example Schemas

User Schema

const patientSchema = new Schema(
  {fullname: {
      type: String,
      required: true,
      trim: true,
      index: true,},
    email: {type: String,
      required: true,
      unique: true,
      lowercase: true,
      trim: true },
    password: {type: String,required: [true, "Password is required"],},
    phonenumber: {type: String,trim: true,},
    profilephoto: {type: String, //cloudinary url},
    reports: {type: [String], //cloudinary url},
    hiddenreports: {type: [String], //cloudinary url},
    hospitals: [{ type: Schema.Types.ObjectId,ref: "Hospital",},],
    dob: { type: String,},
    bloodgroup: { type: String, },
    gender: {type: String,},
    refreshToken: { type: String}},
  {timestamps: true,});
