docs(misc): update generator examples to use new directory/path positional args (#28144)
This PR updates examples in `.md` files (both docs and blog posts) to
use positional args. Nx 20 changes the position arg to be either
`directory` for apps/libs or `path` for artifacts (e.g. components).

So before you'd do this:

```
nx g app myapp --directory=apps/myapp
nx g lib mylib --directory=libs/mylib
nx g lib mylib --directory=libs/nested/mylib
nx g lib @acme/foo --directory=libs/@acme/foo --importPath=@acme/foo
nx g component foo --directory=libs/ui/src/foo --pascalCaseFiles
```

Will now be simplified to

```
nx g app apps/myapp
nx g lib libs/mylib
nx g lib libs/nested/mylib
nx g lib libs/@acme/foo # name and import path are both "@acme/foo"
nx g component libs/ui/src/foo/Foo
```

For cases where `name` and `importPath` need to be changed, you can
always manually specify them.

```
nx g lib libs/nested/foo # name is foo
nx g lib libs/nested/foo --name=nested-foo # specify name with prefix
nx g lib libs/@acme/foo --name # use "foo" as name and don't match importPath
nx g lib libs/@internal/foo --importPath=@acme/foo # different importPath from name

<!-- If this is a particularly complex change or feature addition, you can request a dedicated Nx release for this pull request branch. Mention someone from the Nx team or the `@nrwl/nx-pipelines-reviewers` and they will confirm if the PR warrants its own release for testing purposes, and generate it for you if appropriate. -->

Add a New Fastify Project

Supported Features

Because we are using an Nx plugin for Fastify, all the features of Nx are available.

Create a New Workspace with a Fastify App

If you're starting from scratch, you can use a preset to get you started quickly.

npx create-nx-workspace@latest --preset=node-monorepo --framework=fastify --appName=fastify-api

Then you can skip to the Create a Library section.

If you are adding Fastify to an existing repo, continue to the next section.

Install the Node Plugin

nx add @nx/node

Create an Application

Use the app generator to create a new Fastify app.

{% callout type="note" title="Directory Flag Behavior Changes" %} The command below uses the as-provided directory flag behavior, which is the default in Nx 16.8.0. If you're on an earlier version of Nx or using the derived option, omit the --directory flag. See the as-provided vs. derived documentation for more details. {% /callout %}

nx g @nx/node:app apps/fastify-api

Serve the API by running

nx serve fastify-api

This starts the application on localhost:3000/api by default.

Create a Library

To create a new library, run:

{% callout type="note" title="Directory Flag Behavior Changes" %} The command below uses the as-provided directory flag behavior, which is the default in Nx 16.8.0. If you're on an earlier version of Nx or using the derived option, omit the --directory flag. See the as-provided vs. derived documentation for more details. {% /callout %}

nx g @nx/node:lib libs/my-lib

Once the library is created, update the following files.

export function someFunction(): string {
  return 'some function';
}
import { someFunction } from '@my-org/my-lib';
import { FastifyInstance, FastifyRequest, FastifyReply } from 'fastify';

export default async function (fastify: FastifyInstance) {
  fastify.get(
    '/',
    async function (request: FastifyRequest, reply: FastifyReply) {
      return { message: 'Hello API ' + someFunction };
    }
  );
}

Now when you serve your API, you'll see the content from the library being displayed.
