This plugin allow you to build cross platform sorftware with typescript, supporting architecture for different platform/framework combinations. Nx Cross DDD Plugin is an added value pack for Nx Workspace which provides additional schematics which automate slicing your Nx workspace into domains, feature layers and platforms UI layers according to Nrwl's best practices and about DDD and SOLID programming software pattern.

Overview

• Introduction Slides
• Example Application

Features

• ✅ Architect, test, and build software at any scale according DDD and SOLID programming sorftware pattern best practices
• ✅ Create domains with domain libraries including models and data services
• ✅ Create features with domain feature libraries including facades, models, and data services
• ✅ Create platforms UI with platform feature libraries including feature components build with multi framework available
• ✅ Share libraries of a Monorepo
• ✅ Add linting rules for access restrictions between domains as proposed by Nrwl
• ✅ Add linting rules for access restrictions between domain features layers and platforms UI layers as proposed by Nrwl
• ✅ Support for many frontend and backend technologies
• ✅ Add tooling for build and publish registery librairies automation

Install
