Prisma
Next-generation ORM for Node.js and TypeScript
Prisma helps app developers build faster and make fewer errors with an open source ORM for PostgreSQL, MySQL and SQLite. Central to Prisma is the schema, a declarative way to define your app's data models and their relations that's human-readable. And you don't have to painstakingly create it from scratch if you already have a database - prisma introspect takes care of that. Prisma Client is a query builder that composes the way you think and gets auto-generated from the Prisma schema with types tailored to your app. We designed the API to be intuitive for both SQL veterans and people brand new to databases. Auto-completion, linting, formatting and more help Prisma developers in VSCode stay confident without distractions. Prisma Client puts extra emphasis on extensive type safety for more productive development in TypeScript. Prisma is a server-side library that helps your app read and write data to the database in an intuitive and safe way. -

Primer CSS
The CSS design system that powers GitHub
Our goal is to create a system that enables us to build consistent user experiences with ease, yet with enough flexibility to support the broad spectrum of GitHub websites. This goal is embedded in our design and code decisions. Our approach to CSS is influenced by Object-Oriented CSS principles, functional CSS, and BEM architecture. Styles can be mixed and matched to achieve many different layouts, independent of their location. These styles fall into three categories. Single-purpose, immutable styles, that do one thing well. Abstracted patterns for frequently used visual styles. Primer CSS is built upon systems that form the foundation of our styles such as spacing, typography, and color. This systematic approach helps ensure our styles are consistent and interoperable with each other. The base-8 spacing scale is highly composable and works with the density of GitHub’s content. Margin and padding spacers bring consistency to vertical and horizontal rhythm. -

Sequelize
A promise-based multi SQL dialect Node.js ORM
Sequelize is a promise-based Node.js ORM for Postgres, MySQL, MariaDB, SQLite and Microsoft SQL Server. It features solid transaction support, relations, eager and lazy loading, read replication and more. Sequelize follows SEMVER. Supports Node v6 and above to use ES6 features. Sequelize v5 was released on March 13, 2019. Official TypeScript typings are now included. Sequelize can be used since the beginning in order to automate the creation of every table in your database. Models are the essence of Sequelize. A model is an abstraction that represents a table in your database. In Sequelize, it is a class that extends Model. The model tells Sequelize several things about the entity it represents, such as the name of the table in the database and which columns it has (and their data types). -

peewee
A small, expressive orm, which supports postgresql, mysql and sqlite
Peewee is a simple and small ORM. It has few (but expressive) concepts, making it easy to learn and intuitive to use. Peewee will automatically infer the database table name from the name of the class. You can override the default name by specifying a table_name attribute in the inner “Meta” class (alongside the database attribute). To learn more about how Peewee generates table names, refer to the Table Names section. There are lots of field types suitable for storing various types of data. Peewee handles converting between pythonic values and those used by the database, so you can use Python types in your code without having to worry. The real strength of our database is in how it allows us to retrieve data through queries. Relational databases are excellent for making ad-hoc queries. Peewee provides a magical helper fn(), which can be used to call any SQL function. -

reform
A better ORM for Go, based on non-empty interfaces and code generation
A better ORM for Go and database/sql. It uses non-empty interfaces, code generation (go generate), and initialization-time reflection as opposed to interface{}, type system sidestepping, and runtime reflection. It will be kept simple. Now you can say that last invocation is obviously invalid, and that it's not hard to make an ORM to accept both first and second versions. Make sure you are using Go 1.13+, and Go modules support is enabled. Install or update reform package, reform and reform-db commands. Compiler can't check it. Method's signature in godoc will not tell us how to use it. We are essentially working against those tools by sidestepping type system. First version is still invalid, since one would expect Save() method to set record's primary key after INSERT, but this change will be lost due to passing by value. -

xorm
xorm is a simple and powerful Go language ORM library
xorm is a simple and powerful Go language ORM library, through which database operations can be made very easy. This library is a customized and enhanced version based on the original xorm, which provides xorm with ibatis-like configuration files and dynamic SQL support, and supports ActiveRecord operations. This library is based on the customized and enhanced version of the original xorm. Since this customized version has third-party library dependencies (the original version of xorm does not have any third-party library dependencies), the original version of xorm must maintain The third-party library has zero dependencies, so I had to open this Github library separately. The relevant customization functions of this library are developed to solve simpler complex SQL calls and some special business requirements scenarios. The core functions of this customized version of ORM are consistent with the original version, and will be updated with the original version of xorm. -

Analogue ORM
Analogue ORM : Data Mapper ORM for Laravel/PHP
Analogue is a flexible, easy-to-use ORM for PHP. It is a transposition of the Eloquent ORM that ships with Laravel framework using a Data Mapper pattern instead of the original Active Record approach. it overcomes some of Eloquent's architectural limitations by using a strict separation of concerns; for example, you can use Value Objects or Single-table-inheritance, which are hard/impossible to implement correctly using the native ORM. As a Laravel package, it integrates flawlessly inside the framework, and provides a more powerfull peristance layer, allowing to build enterprise-grade applications while retaining a simple and enjoyable development experience. -

Ardent
Self-validating, secure and smart models for Laravel's Eloquent ORM
Self-validating, secure and smart models for Laravel's Eloquent ORM. Based on the Aware bundle for Laravel 3 by Colby Rabideau. Add laravelbook/ardent as a requirement to composer.json. You can also add the package using composer require laravelbook/ardent and later specifying the version you want (for now, dev-master is your best bet). The magic-dust-powered, wrist-friendly, one-stop solution to all your dreary input sanitization boilerplates! Puns aside, input validation functionality can quickly become tedious to write and maintain. Ardent deals away with these complexities by providing helpers for automating many repetitive tasks. Ardent is not just great for input validation, though, it will help you significantly reduce your Eloquent data model code. Ardent is particularly useful if you find yourself wearily writing very similar code time and again in multiple individual applications. -

AutoMapper
A convention-based object-object mapper in .NET
A convention-based object-object mapper. 100% organic and gluten-free. Takes out all of the fuss of mapping one object to another. AutoMapper is a simple little library built to solve a deceptively complex problem, getting rid of code that mapped one object to another. This type of code is rather dreary and boring to write, so why not invent a tool to do it for us? First, install NuGet. Then, install AutoMapper from the package manager console. AutoMapper is an object-object mapper. Object-object mapping works by transforming an input object of one type into an output object of a different type. What makes AutoMapper interesting is that it provides some interesting conventions to take the dirty work out of figuring out how to map type A to type B. As long as type B follows AutoMapper’s established convention, almost zero configuration is needed to map two types.
