Generators support React routes and boundaries plus component, action, middleware, hook, context, model, class, interface, enum, and test. NestJS backend schematics include controller, resource, service, module, and guard; the CLI writes them to app/server and registers them in the root AppModule. Nest-style aliases such as p, co, res, s, mo, mi, gu, and spec are available.

Official aliases passed to ness add, remove, or update resolve to the @nessframework/* scope, so ness add tailwind installs @nessframework/tailwind.

--template accepts the official default, typescript, minimal, api, and dashboard aliases, npm packages, package-style templates, and direct local directories through relative, absolute, ~/, or file: paths. Official starters keep framework settings in one ness.config.mjs file.

Node.js 20.19 or newer is required.
