Sequelize VS PostgreSQL

Sequelize - modern Typescript and NodeJS ORM for Oracle, Postgres, MySQL, MariaDB, SQLite, SQL Server+docs

If you use Sequalize, TypeORM or for MongoDB, we have Mongoose these types of ORM tools, then you are safe by default because these help us against the SQL query injection attacks by default.

Our orders microservice will have its own set of teachnologies just like we earlier plotted that is mysql database and sequelize orm. MySQL is an open-source relational database management system (RDBMS) that is widely used for building web applications and managing data. It is a popular choice for many developers and organizations due to its performance, reliability, and ease of use. Sequelize is a popular Object-Relational Mapping (ORM) library for Node.js. It provides a way to interact with relational databases like MySQL, PostgreSQL, SQLite, and MSSQL using JavaScript or TypeScript. It simplifies database operations by allowing developers to use JavaScript objects to represent database tables and records, instead of writing raw SQL queries. In this microservice, we will use it to query our MySQL database.

However, some ORM operations can’t be translated into a single SQL query that easily. Let’s take Sequelize's findOrInsert. It first sends a SELECT query like this:

Sequelize is an extensively employed ORM for Node.js. It supports relational databases, such as MySQL, PostgreSQL, SQLite, and MSSQL. Sequelize boasts a comprehensive array of features for database modeling and querying. It caters to various coding styles by accommodating both Promise and Callback-based APIs. Moreover, it encompasses advanced functionalities such as transactions, migrations, and associations, making it well-suited for intricate database operations.

I made a small change to the new documentation for Sequelize! I was just scrolling through the documentation and found this mistake that could lead others to weird debugging sessions, so as soon as I found it, I submitted a PR for them! You can check out the contribution here!

The image above is a chart comparing three popular ORM tools from the npmtrends.com. ERDIA only supports TypeORM for now, but the roadmap is to support Sequelize and Prisma as well.

I tried every solution in this guide https://github.com/sequelize/sequelize/issues/6907 and many others, but I feel that Next 13 is the latest and it is not supporting other ORMs than Prisma. And I am not comfortable working with Prisma due to the absence of migrations, CLI and so much more.

I mean I am not really a pro be dev. But there is such tools as https://sequelize.org/ and it can work with different DBs, if your current DB doesn't support this you can always switch to that one which do. Switching to another language doesn't really do much.

SQL (Structured Query Language) databases are relational databases. They organize data into tables with rows and columns, and they use SQL for querying and managing data. Examples include MySQL, PostgreSQL, and SQLite.

Node.js, MySQL and PostgreSQL servers installed on your machine

Each app’s front end is built with Qwik and uses Tailwind for styling. The server-side is powered by Qwik City (Qwik’s official meta-framework) and runs on Node.js hosted on a shared Linode VPS. The apps also use PM2 for process management and Caddy as a reverse proxy and SSL provisioner. The data is stored in a PostgreSQL database that also runs on a shared Linode VPS. The apps interact with the database using Drizzle, an Object-Relational Mapper (ORM) for JavaScript. The entire infrastructure for both apps is managed with Terraform using the Terraform Linode provider, which was new to me, but made provisioning and destroying infrastructure really fast and easy (once I learned how it all worked).

I've used MySQL for years. But recently, I found myself working PostgreSQL and simple things like dumping and restoring a database are different enough that I decided to document the process. It's straightforward enough once I knew how.

A running Rails application needs a database to connect to. You may already have your database of choice installed, but if not, I recommend PostgreSQL, or Postgres for short. On a Mac, probably the easiest way to install it is with Posrgres.app. Another option, the one I prefer, is to use Homebrew. With Homebrew installed, this command will install PostgreSQL version 16 along with libpq:

PostgreSQL

PostgreSQL: Offers a robust feature set and strong compliance with SQL standards, making it suitable for a wide range of applications, from simple to complex, particularly where data integrity and extensibility are key.

FerretDB is an open source document database that adds MongoDB compatibility to other database backends, such as Postgres and SQLite. By using FerretDB, developers can access familiar MongoDB features and tools using the same syntax and commands for many of their use cases.

To better understand how SQL injection works, let's quickly create a vulnerable app using Node.js, Express, and a PostgreSQL database. The application takes user input from a form, constructs a SQL query, and executes it against the database to fetch some data.

We'll use PostgreSQL, and first of all, you need to install PostgreSQL if you haven't installed it yet. https://www.postgresql.org/
