warning: Don not use this in real project, it is unstable

Installation

You need: Node.js installed on your machine.

To install

$ npm i mysqloose

Importing

const mysqloose = require("mysqloose");

Important: Turn on mysql server before using

Overview

Connecting to MySQL

First, we need to define a connection.

mysqloose.connect(
  "mysql://<user>:<password>@<hostname>/<database_name>",
  (err) => {
    if (err) throw err;
  }
);

Defining a Model

Models are defined through the Schema interface. Unlike mongoose, you can not define a model without mysqloose.connect

mysqloose.connect(
  "mysql://<user>:<password>@<hostname>/<database_name>",
  (err) => {
    if (err) throw err;
  }
);
 
const Schema = mysqloose.Schema;
 
const UserSchema = new Schema({
  id: 'INT NOT NULL AUTO_INCREMENT PRIMARY KEY' // mysqloose do not have ObjectId yet
  user_name: 'VARCHAR(40) NOT NULL',
  email: 'VARCHAR(255) NOT NULL',
  password: 'varchar(60) not null' // Case-insensitive
  user_type: 'varchar(5) default "user"'
});

Accessing a Model

const User = mongoose.model("ModelName", UserSchema);
 
const newUser = new User({
  user_name: "user name",
  email: "email",
  password: "password",
});

Insert

newUser.save((err) => {
  if (err) throw err;
});

Select

Synchronous

User.find({ name: "name" }, (err, result) => {
  if (err) throw err;
  console.log(result);
});
 
// Must use {<somethingId>: <number>}
User.findById({ id: 1 }, "name email", (err, result) => {
  if (err) throw err;
  console.log(result);
});
 
User.findOne({ name: "name" }, (err, result) => {
  if (err) throw err;
  console.log(result);
});

Asynchronous

User.find({ name: "name" })
  .then((result) => {
    console.log(result);
  })
  .catch((err) => {
    if (err) throw err;
  });
 
User.findById({ id: 1 }, "name email")
  .then((result) => {
    console.log(result);
  })
  .catch((err) => {
    if (err) throw err;
  });
 
User.findOne({ name: "name" })
  .then((result) => {
    console.log(result);
  })
  .catch((err) => {
    if (err) throw err;
  });

Update

User.updateOne({ name: "name" }, { email: "new email" }, (err, result) => {
  if (err) throw err;
  console.log(result);
});

Delete

User.deleteOne({ name: "name" }, (err, result) => {
  if (err) throw err;
  console.log(result);
});
