TypeORM is an ORM that can run in NodeJS, Browser, Cordova, PhoneGap and Ionic platforms and can be used with TypeScript and JavaScript (ES5, ES6, ES7). Its goal to always support latest JavaScript features and provide features that help you to develop any kind of applications that use databases - from small applications with a few tables to large scale enterprise applications with multiple databases.
 
TypeORM supports both Active Record and Data Mapper patterns, unlike all other JavaScript ORMs currently exist, which means you can write high quality, loosely coupled, scalable, maintainable applications the most productive way.

Typeorm - Amazing ORM for TypeScript and JavaScript (ES7, ES6, ES5)

MikroORM is a TypeScript ORM for Node.js based on Data Mapper, Unit of work and Identity Map patterns. It supports MongoDB, MySQL, MariaDB, PostgreSQL and SQLite databases. Heavily inspired by Doctrine and Nextras ORM.
 
It allows handling transactions automatically. When you call em.flush() all computed changes are wrapped inside a database transaction. It uses source code analysis so you do not have to repeat yourself when defining entities. Simply define correct TypeScript types and you are good to go.
 
Its features include:
<ul>
<li>Clean and Simple Entity Definition</li>
<li>Identity Map</li>
<li>Entity References</li>
<li>Using Entity Constructors</li>
<li>Modelling Relationships</li>
<li>Collections</li>
<li>Unit of Work</li>
<li>Transactions</li>
<li>Cascading persist and remove</li>
<li>Composite and Foreign Keys as Primary Key</li>
<li>Filters</li>
<li>Using QueryBuilder</li>
<li>Preloading Deeply Nested Structures via populate</li>
<li>Property Validation</li>
<li>Lifecycle Hooks</li>
<li>Vanilla JS Support</li>
<li>Schema Generator</li>
<li>Entity Generator</li>
</ul>

Prisma helps app developers build faster and
make fewer errors with an open source ORM for PostgreSQL, MySQL and SQLite. It makes database access easy with an auto-generated and type-safe query builder that's tailored to your database schema. It provides an alternative to traditional ORMs and SQL query builders. 
 
Prisma is the perfect companion for building web APIs. It saves repetitive CRUD boilerplate and provides a flexible API for common use cases such as pagination and filtering. Based on the Prisma Schema, Prisma Migrate automatically generates SQL database migrations, that are fully customizable.

Prisma - Next-generation ORM for Node.js and TypeScript

SQLx is an async, pure Rust SQL crate featuring compile-time checked queries without a DSL. It is truly Asynchronous. Built from the ground-up using async/await for maximum concurrency. It has support for PostgreSQL, MySQL, SQLite, and MSSQL. 
 
SQLx supports compile-time checked queries. It does not, however, do this by providing a Rust API or DSL (domain-specific language) for building queries. Instead, it provides macros that take regular SQL as an input and ensure that it is valid for your database. The way this works is that SQLx connects to your development DB at compile time to have the database itself verify (and return some info on) your SQL queries.
