bug: nodeResolve.customResolveOptions is a deprecated option in a Stencil Configuration file

Prerequisites

• I have read the Contributing Guidelines.
• I agree to follow the Code of Conduct.
• I have searched for existing issues that already report this problem, without success.

Stencil Version

4.22.3

Current Behavior

Using stencil config like:

export const config: Config = {
  namespace: 'web-components',
  tsconfig: 'tsconfig.lib.json',
  nodeResolve: {
    customResolveOptions: {
      moduleDirectory: [
        '../../dist/node_modules',
        '../../node_modules'
      ]
    }
  },
...

To use a local build output node_modules in addition to normal node_modules.

This works as expected, but I receive the following warning with each build:

[51:23.7]  @stencil/core
[51:24.0]  v4.22.3

[ WARN  ]  Build Warn
           nodeResolve.customResolveOptions is a deprecated option in a Stencil Configuration file. If you need this
           option, please open a new issue in the Stencil repository
           (https://github.com/ionic-team/stencil/issues/new/choose)

Expected Behavior

No warning.

@johnc-ftl thanks for raising this issue.

This field is used to configure @rollup/plugin-node-resolve when generating any non-documentation output target artifacts. the contents of this option get propagated by the rollup plugin to resolve, which does the actual resolution of files in stencil's in-memory filesystem. In newer versions of @rollup/plugin-node-resolve, this option has been removed, which no option to override defaults (creating a separation of concerns between the plugin and resolve).

To use a local build output node_modules in addition to normal node_modules.

Can you please elaborate on your use case and provide maybe a minimal example for this?

[johnc-ftl]

Hi @christian-bromann - thank you for the explanation. I appreciate you all having the deprecation warning vs stopping working :)

Our use case is that we have some internal libraries, that we build first, and that our stencil project depends on. Those libraries write their build output to:

./dist/node_modules

whereas all the normal/external NPM dependencies are written to:

./node_modules.

The Stencil project has external and internal dependencies, thus the config above.

Are you aware of another way to configure dependency resolution to resolve from both directories? I'm happy to switch to another approach that works.
