Explain Data Structure

Importing Mongoose

const mongoose = require("mongoose");

The first line of the code imports the mongoose library, which is a tool for working with MongoDB, a database system that stores data in JSON-like documents. Mongoose provides a schema-based solution to model the data and perform various operations on it.

Creating user IDs

const userIds = [
  mongoose.Types.ObjectId(),
  mongoose.Types.ObjectId(),
  mongoose.Types.ObjectId(),
  mongoose.Types.ObjectId(),
  mongoose.Types.ObjectId(),
  mongoose.Types.ObjectId(),
  mongoose.Types.ObjectId(),
  mongoose.Types.ObjectId(),
];

The next few lines of the code create an array of user IDs, which are unique identifiers for each user in the database. The user IDs are generated using the mongoose.Types.ObjectId() method, which creates a 12-byte hexadecimal value.

Creating user data

The next part of the code creates an array of user objects, which contain various properties for each user, such as firstName, lastName, email, password, picturePath, friends, location, occupation, viewedProfile, impressions, createdAt, updatedAt, and __v. The values for these properties are either hard-coded or randomly generated using some library or tool. For example, the password property is hashed using a bcrypt algorithm, and the picturePath property is a file name of an image stored somewhere.

export const users = [
  {
    _id: userIds[0],
    firstName: "test",
    lastName: "me",
    email: "aaaaaaa@gmail.com",
    password: "$2b$10$dsasdgsagasda//G9JxQ4bQ8KXf4OAIe/X/AK9skyWUy",
    picturePath: "p11.jpeg",
    friends: [],
    location: "San Fran, CA",
    occupation: "Software Engineer",
    viewedProfile: 14561,
    impressions: 888822,
    createdAt: 1115211422,
    updatedAt: 1115211422,
    __v: 0,
  },
  // more user objects
];

Creating post data

The last part of the code creates an array of post objects, which contain various properties for each post, such as _id, userId, firstName, lastName, location, description, picturePath, userPicturePath, likes, comments. The values for these properties are either hard-coded or randomly generated using some library or tool. For example, the _id property is generated using the mongoose.Types.ObjectId() method, and the likes property is a map of user IDs and boolean values.

export const posts = [
  {
    _id: new mongoose.Types.ObjectId(),
    userId: userIds[1],
    firstName: "Steve",
    lastName: "Ralph",
    location: "New York, CA",
    description: "Some really long random description",
    picturePath: "post1.jpeg",
    userPicturePath: "p3.jpeg",
    likes: new Map([
      [userIds[0], true],
      [userIds[2], true],
      [userIds[3], true],
      [userIds[4], true],
    ]),
    comments: [
      "random comment",
      "another random comment",
      "yet another random comment",
    ],
  },
  // more post objects
];

Conclusion

  • The code uses mongoose to create fake data for a social media application.
  • The code creates user IDs, users, and posts with various properties and values.
  • The code exports the users and posts arrays for other modules to use.
