tspace-mysql is an Object-Relational Mapping (ORM) tool designed to run seamlessly in Node.js and is fully compatible with TypeScript. It consistently supports the latest features in both TypeScript and JavaScript, providing additional functionalities to enhance your development experience.
| Feature | Description |
|---|---|
| Query Builder | Create flexible queries like SELECT, INSERT, UPDATE, and DELETE. You can also use raw SQL. |
| Join Clauses | Use INNER JOIN, LEFT JOIN, RIGHT JOIN, and CROSS JOIN to combine data from multiple tables. |
| Model | Provides a way to interact with database records as objects in code. You can perform create, read, update, and delete (CRUD) operations. Models also support soft deletes and relationship methods. |
| Schema | Allows you to define and manage the structure of MySQL tables, including data types and relationships. Supports migrations and validation. |
| Validation | Automatically checks data against defined rules before saving it to the database, ensuring data integrity and correctness. |
| Sync | Synchronizes the model structure with the database, updating the schema to match the model definitions automatically. |
| Soft Deletes | Marks records as deleted without removing them from the database. This allows for recovery and auditing later. |
| Relationships | Set up connections between models, such as one-to-one, one-to-many, belongs-to, and many-to-many. Supports nested relationships and checks. |
| Type Safety | Ensures that queries are safer by checking the types of statements like SELECT, ORDER BY, GROUP BY, and WHERE. |
| Repository | Follows a pattern for managing database operations like SELECT, INSERT, UPDATE, and DELETE. It helps keep the code organized. |
| Decorators | Use decorators to add extra functionality or information to model classes and methods, making the code easier to read. |
| Caching | Improves performance by storing frequently requested data. Supports in-memory caching (like memory DB) and Redis for distributed caching. |
| Migrations | Use CLI commands to create models, make migrations, and apply changes to the database structure. |
| Blueprints | Create a clear layout of the database structure and how models and tables relate to each other. |
| CLI | A Command Line Interface for managing models, running migrations, executing queries, and performing other tasks using commands (like make:model, migrate, and query). |

To establish a connection, the recommended method for creating your environment variables is by using a '.env' file. using the following:
DB_HOST = localhost;
DB_PORT = 3306;
DB_USERNAME = root;
DB_PASSWORD = password;
DB_DATABASE = database;
/**
* @default
* DB_CONNECTION_LIMIT = 10
* DB_QUEUE_LIMIT = 0
* DB_TIMEOUT = 60000
* DB_DATE_STRINGS = false
*/You can also create a file named 'db.tspace' to configure the connection. using the following:
source db {
host = localhost
port = 3306
database = npm
user = root
password = database
connectionLimit = 10
dateStrings = true
connectTimeout = 60000
waitForConnections = true
queueLimit = 0
charset = utf8mb4
}import { sql , OP } from 'tspace-mysql'
// select
await sql()
.select('id','name')
.from('users')
.where({
'name' : 'tspace'
'id' : OP.in([1,2,3])
})
.limit(3)
.orderBy('name')
// insert
await sql()
.insert('users')
.values({
email : 'tspace@example.com'
})
// insert return data
await sql()
.insert('users')
.values({
email : 'tspace@example.com'
})
.returning({
id : true,
email : true,
enum : true
})
// update
await sql()
.update('users')
.where({
id : 1
})
.set({
email : 'tspace@example.com'
})
// update return data
await sql()
.update('users')
.where({
id : 1
})
.set({
email : 'tspace@example.com'
})
.returning()
//delete
await sql()
.delete('users')
.where({
id : 1
})
How a database query builder works with a simple example using the following:
+-------------+--------------+----------------------------+
| table users |
+-------------+--------------+----------------------------+
| id | username | email |
|-------------|--------------|----------------------------|
| 1 | tspace | tspace@gmail.com |
| 2 | tspace2 | tspace2@gmail.com |
+-------------+--------------+----------------------------+
+-------------+--------------+----------------------------+
| table posts |
+-------------+--------------+----------------------------+
| id | user_id | title |
|-------------|--------------|----------------------------|
| 1 | 1 | posts tspace |
| 2 | 2 | posts tspace2 |
+-------------+--------------+----------------------------+import { DB } from 'tspace-mysql'

// "admin\' OR \'1\'=\'1"
//XSS
const input = "text hello!<script>alert('XSS attack');</script>";
DB.escapeXSS(input);
// "text hello!"To get started, install the 'tspace-mysql' package globally using the following npm command:

.findMany()Relationships can return results only if they are not empty in relations, considering soft deletes. Let's illustrate this with an example of an existence check in relations:

*/Relationships can return results only if they are deleted in table, considering soft deletes. Let's illustrate this with an example:
+-------------+--------------+----------------------------+--------------------+

+-------------+--------------+----------------------------+--------------------+
| id | username | email | deleted_at |
|-------------|--------------|----------------------------|--------------------|
| 1 | tspace1 | tspace1@gmail.com | |
| 2 | tspace2 | tspace2@gmail.com | |
| 3 | tspace3 | tspace3@gmail.com |2020-07-15 00:00:00 |
+-------------+--------------+----------------------------+--------------------+
+-------------+--------------+----------------------------+--------------------+
| table posts | |
+-------------+--------------+----------------------------+--------------------+
| id | user_id | title | deleted_at |
|-------------|--------------|----------------------------|--------------------|

*/Certainly, let's illustrate the use of a built-in function in the results of relationships:
import { Model } from 'tspace-mysql'
class User extends Model {
constructor(){
super()
this.hasMany({ name : 'posts' , model : Post })
this.useBuiltInRelationFunctions()
}
}
+--------------------------------------------------------------------------+
class Post extends Model {
constructor(){
super()
this.hasMany({ name : 'comments' , model : Comment })
this.belongsTo({ name : 'user' , model : User })
this.useBuiltInRelationFunctions()
}
}
+--------------------------------------------------------------------------+
class Comment extends Model {
constructor(){
super()
this.hasMany({ name : 'users' , model : User })
this.belongsTo({ name : 'post' , model : Post })
this.useBuiltInRelationFunctions()
}
}
+--------------------------------------------------------------------------+
const user = await new User().findOne()
const posts = await user.$posts()
/** Warning built-in function has Big-O effect */
for (const post of posts) {
const comments = await post.$comments()
}Cache can be used in a Model. Let's illustrate this with an example of a cache:
// support memory db and redis
// set cache in file config .env , .env.development ... etc
DB_CACHE = memory // by default
// for db
DB_CACHE = db
// for redis
DB_CACHE = redis://username:password@server:6379
const users = await new User()
.cache({
key : 'users', // key of the cache
expires : 1000 * 60 // cache expires in 60 seconds
})
.sleep(5) // assume the query takes longer than 5 seconds...
.findMany()Decorators can be used in a Model. Let's illustrate this with an example of a decorators:
import {
Blueprint, Model ,
Table ,TableSingular, TablePlural,
UUID, SoftDelete, Timestamp,
Pattern, CamelCase , snakeCase ,
Column, Validate, Observer
} from 'tspace-mysql'
import { Post } from './Post'
import { PostUser } from './PostUser'
class UserObserve {
public selected(results) {
console.log({ results , selected : true })
}
public created(results) {
console.log({ results , created : true })
}
public updated(results) {
console.log({ results , updated : true })
}
public deleted(results) {
console.log({ results , deleted : true })
}
}
@Pattern('camelCase')
@Observer(UserObserve)
@UUID()
@SoftDelete()
@Timestamp()
@Table('users')
class User extends Model {
@Column(() => Blueprint.int().notNull().primary().autoIncrement())
public id!: number
@Column(() => Blueprint.varchar(50).null())
public uuid!: string
@Column(() => Blueprint.varchar(50).null())
@Validate({
type : String,
require : true,
length : 50,
match: /^[a-zA-Z0-9._]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$/,
unique : true,
fn : (email : string) => /^[a-zA-Z0-9._]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$/.test(email)
})
public email!: string
@Column(() => Blueprint.varchar(50).null())
public name !: string
@Column(() => Blueprint.varchar(50).null())
public username !: string
@Column(() => Blueprint.varchar(50).null())
public password !: string
@Column(() => Blueprint.timestamp().null())
public createdAt!: Date
@Column(() => Blueprint.timestamp().null())
public updatedAt!: Date
@Column(() => Blueprint.timestamp().null())
public deletedAt!: Date
}
export { User }
export default UserThe schema refers to the structure of the database as it pertains to the objects and classes in the model. using the following:
import { Model, Blueprint , TSchema } from "tspace-mysql";
const schema = {
id: Blueprint.int().notNull().primary().autoIncrement(),
uuid: Blueprint.varchar(50).null().index(),
name: Blueprint.varchar(191).notNull(),
email: Blueprint.varchar(191).notNull(),
createdAt: Blueprint.timestamp().null(),
updatedAt: Blueprint.timestamp().null(),
deletedAt: Blueprint.timestamp().null()
}
// make type in TS
type TS = TSchema<typeof Schema>
// the TSchemaUser will be created like that
/**
{
id : number,
uuid : string | null,
name : string,
email : string,
createdAt : Date | string | null,
updatedAt : Date | string | null,
deletedAt : Date | string | null
}
*/
class User extends Model<TS> // use the schema for this User model
{
constructor() {
super();
this.useCamelCase()
this.useSchema(schema)
}
}Validate the schema of Model let's example a validator model:
import { Model, Blueprint } from "tspace-mysql";
class User extends Model {
constructor() {
super();
this.useCamelCase();
this.useSchema({
id: Blueprint.int().notNull().primary().autoIncrement(),
uuid: Blueprint.varchar(50).null(),
name: Blueprint.varchar(191).notNull(),
email: Blueprint.varchar(191).notNull(),
createdAt: Blueprint.timestamp().null(),
updatedAt: Blueprint.timestamp().null(),
deletedAt: Blueprint.timestamp().null(),
});
// validate input when create or update reference to the schema in 'this.useSchema'
this.useValidateSchema({
id: Number,
uuid: Number,
name: {
type: String,
length: 191,
require: true,
json: true,
},
email: {
type: String,
require: true,
length: 191,
match: /^[a-zA-Z0-9._]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$/,
unique: true,
fn: (email: string) => {
return /^[a-zA-Z0-9._]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$/.test(email)
}
},
createdAt: Date,
updatedAt: Date,
deletedAt: Date,
});
}
}Sync the schema with the "Models" setting in your directory. This process will verify and update table columns and foreign keys as needed. Ensure that the relationships are correctly established through the 'useSchema' method in your models. Let's examine a basic sync class:
/**
*
* @Ex directory
*
* - node_modules
* - src
* - index.ts
* - Models
* - User.ts
* - Post.ts
*/
// file User
class User extends Model {
constructor() {
super();
this.hasMany({ name: "posts", model: Post });
// if you need to initialize data when creating the table, you can use the following.
this.whenCreatingTable(async () => {
return await new User()
.create({
...columns,
})
.void()
.save();
});
this.useSchema({
id: Blueprint.int().notNull().primary().autoIncrement(),
uuid: Blueprint.varchar(50).null(),
email: Blueprint.int().notNull().unique(),
name: Blueprint.varchar(255).null(),
created_at: Blueprint.timestamp().null(),
updated_at: Blueprint.timestamp().null(),
deleted_at: Blueprint.timestamp().null(),
});
}
}
// file Post
import User from "./User";
class Post extends Model {
constructor() {
super();
this.hasMany({ name: "comments", model: Comment });
this.belongsTo({ name: "user", model: User });
this.useSchema({
id: Blueprint.int().notNull().primary().autoIncrement(),
uuid: Blueprint.varchar(50).null(),
user_id: Blueprint.int().notNull().foreign({
references: "id",
on: User,
onDelete: "CASCADE",
onUpdate: "CASCADE",
}),
title: Blueprint.varchar(255).null(),
created_at: Blueprint.timestamp().null(),
updated_at: Blueprint.timestamp().null(),
deleted_at: Blueprint.timestamp().null(),
});
}
}
await Schema.sync(`/src/Models`, {
force: true,
log: true,
foreign: true,
changed: true,
});
// You can also synchronize using the Model.
await new User().sync({ force: true, foreign: true, changed: true });import { Model } from 'tspace-mysql'
class User extends Model {
constructor() {
super()
this.useSoftDelete() // All query will be where 'deleted_at' is null
// You can also use patterns camelCase to covert the 'deleted_at' to 'deletedAt'
// You can also customize the column 'deleted_at'
this.useSoftDelete('deletedAtCustom')
}
}
const user = await new User().where('user_id',1).findOne()
// SELECT * FROM `users` WHERE `users`.`userId` = '1' and `users`.`deletedAtCustom` IS NULL LIMIT 1;
// find in trashed
const user = await new User().trashed().findMany()
// SELECT * FROM `users` WHERE `users`.`userId` = '1' and `users`.`deletedAtCustom` IS NOT NULL;Type safety in TypeScript refers to the ability of the language to detect and prevent type errors during compile-time. Type safety still works when you add additional types to your model, using the following:
// in file User.ts
import { Model , Blueprint , TSchema , TSchemaStatic } from 'tspace-mysql'
import Phone from '../Phone'
const schemaUser = {
id :Blueprint.int().notNull().primary().autoIncrement(),
uuid :Blueprint.varchar(50).null(),

name :Blueprint.varchar(255).null(),
username : Blueprint.varchar(255).null(),
password : Blueprint.varchar(255).null(),
createdAt :Blueprint.timestamp().null(),
updatedAt :Blueprint.timestamp().null()
}
type TSchemaUser = TSchemaStatic<typeof schemaUser>
// TSchemaUser = TSchema<typeof schemaUser>
// TSchema allowed to set any new keys without in the schema to results
// TSchemaStatic not allowed to set any new keys without in the schema to results
class User extends Model<TSchemaUser> { // Add this '<TSchemaUser>' to activate the type for the Model.
constructor() {

})Blueprint is a tool used for defining database schemas programmatically. It allows developers to describe the structure of their database tables using a simple and intuitive syntax rather than writing SQL queries directly., you may use the:
import { Schema , Blueprint , DB } from 'tspace-mysql'
(async () => {
await new Schema().table('users', {
id : Blueprint.int().notNull().primary().autoIncrement(),
// or id : Blueprint.serial().primary(),
uuid : Blueprint.varchar(120).null()
name : Blueprint.varchar(120).default('name'),
email : Blueprint.varchar(255).unique().notNull(),
email_verify : Blueprint.tinyInt(),
password : Blueprint.varchar(255),
json : Blueprint.json(),
created_at : Blueprint.null().timestamp(),
updated_at : Blueprint.null().timestamp(),
deleted_at : Blueprint.null().timestamp()
})
/**

index()To get started, let's install tspace-mysql you may use a basic cli :
npm install tspace-mysql -g
The command will be placed Model in the specific directory.
/**

// => migrate all schemas in folder <Migrations>. created into databaseThe command will execute a query.
tspace-mysql query "SELECT * FROM users"
The command will dump the database or table into a file.
tspace-mysql dump:db --dir=<folder for dump> --values // backup with values in the tables
tspace-mysql dump:table "table_name" --dir=<folder for dump> --values // backup with values in the table
The command will generate models from tables in the database.
tspace-mysql generate:models --dir=<folder for creating>
tspace-mysql generate:models --dir=app/Models --env=development --decorators
The command will generate migrations based on the schema in your models to a .sql file, can also push the migration files to the database.
