Nx

Nx is an open-source suite of tools designed to manage monorepos, developed by Nrwl. It helps coordinate multiple applications and libraries within a single repository, enabling scalable development workflows across frontend and backend projects. Nx provides tooling for code generation, project configuration, and task orchestration, with features intended to improve consistency and build speed across teams.

Nx originated as an extension to the Angular CLI to support large Angular-based monorepos, created by Victor Savkin and Jeff Cross of Nrwl. It expanded beyond Angular to support other ecosystems through plugins and official support for React, Node, NestJS, Next.js, and more. It remains actively maintained and open-source, with a paid cloud offering for advanced caching and distributed computation.

Key features include a dependency graph that shows how projects relate, affected commands that run builds, tests, and lint only for changed parts, and a plugin-based architecture that adds generators and executors. It supports incremental builds and task orchestration with caching, and can run tasks locally or via Nx Cloud for distributed computation. Projects are defined in a workspace using configuration files such as nx.json and workspace.json or project.json, and can be built, tested, linted, and deployed using standardized commands. It is compatible with npm, yarn, and pnpm.

Nx is used in organizations ranging from startups to large enterprises to enforce consistent tooling, accelerate CI pipelines, and enable code sharing through libraries within a monorepo. The ecosystem includes community plugins and official plugins for various frameworks, and tools like Nx Console that assist with generating code and running targets.
