How to call a nx-plugin generator from another nx-plugin generator

[mehrad-rafigh]

Hi there,

I am trying to migrate our workspace generators to a nx-plugin. I am currently having difficulties calling my base generator. I am wrapping it inside wrapAngularDevkitSchematic

Running my generator I get
Package "@cg/nx-extensions" was found but does not support schematics.

What is the way to call a generator from another generator?

Hi,

First of all, you said:

I am wrapping it inside wrapAngularDevkitSchematic
That means your base generator is in fact a schematics ? If so, use the appropriate wording (which is schematics).

In fact, a generator (nx devkit) does not require to be wrapped inside a wrapAngularDevkitSchematic to be called by another generator.

Now to answer your question (assuming you want to call a real nx's generator from another one), I would say 2 things are needed to have this work:

1. your to-be-called generator method must be made public/exported (inside the index.ts of the generator's package)
2. its package.json must have a "generators" property that points to the generators.json declaring the generator (its implementation, schema, etc)

Then in your calling generator just do: await myBaseGenerator(tree, [options]) and you should be good to go!

Since nx 11, schematics are now called generators and that's what I am building ¯_(ツ)_/¯

Yeah...no. You need to wrap calls against schematics from the nx plugin with wrapAngularDevkitSchematic

Well, To be more precised, the wrapping with wrapAngularDevkitSchematic is necesary if your "generator" has been written and exposed with Angular's Devkit API (@angular-devkit/*). If the "generator" is already written with Nrwl's Devkit API (i.e with @nrwl/devkit, new in Nx11),
then this schematics (angular terms) is in fact a generator (in nx11 terms) , and so, no wrapping should be necessary to called it.

Maybe if you share your code I can assist more?
