This moves a bunch of utility functions (and some constants) from src/compiler/output-targets/output-utils.ts to instead live in a new file in the @utils directory (src/utils). This is done to reflect the fact that functions in the file are used outside of the src/compiler/ bundle so they should be pulled out into a common location.

when I was fiddling with build stuff I noticed this relative import from src/compiler/ which was causing code from within the compiler bundle be also pulled into the cli bundle. I considered a bit how to address it - we could export the output targets related utils (and constants) from the compiler bundle, making this into something like

import { isOutputTargetDocs } from '@stencil/core'

but I thought that wasn't too great for a few reasons, mainly that it changes the public API of @stencil/core. I also thought just for organization, if the output target related utils are used across the codebase they should really live in the src/utils directory and therefore be importable from the @utils namespace. So I thought we should look at moving the functions to src/utils/output-target.ts and moving the constants to src/utils/constants.ts

the internal-platform-hydrate bundle depends on functions which use the output-target utils which, in turn, imports path. However, none of the functions which it uses actually use functioned exported by path, so when bundling it doesn't actually import anything from path but if you don't set this option Rollup will leave an unqualified import like so:

import "path";

if you say moduleSideEffects: false you're basically saying 'dont assume that imported a module has a desired side effect' which allows an import that doesn't result in any symbols being pulled into the importing module to be eliminated.

Another way to say this is that without this change the treeshaking validation for test.dist doesn't pass for this bundle.

Couple small things (sorry for the repetition). Also agree w/ Ryan's comment about adding docs/comment for the moduleSideEffects flag.

Can we combine this with the existing @utils import?

This moves a bunch of utility functions (and some constants) from
src/compiler/output-targets/output-utils.ts to instead live in a new
file in the `@utils` directory (`src/utils`). This is done to reflect
the fact that functions in the file are used outside of the
`src/compiler/` bundle so they should be pulled out into a common
location.
