- at least as of TS 2.1: https://www.typescriptlang.org/docs/handbook/utility-types.html#partialtype
- we have a peerDep on TS >=2.4, so should definitely be compatible
- and TS is on ~4.6 at this point, so that's _really_ old
- remove the file and the declarations and declaration maps
- don't rebuild as that's usually done as a separate commit
- this was introduced in v4.1.0 of @rollup/pluginutils:
https://github.com/rollup/plugins/blob/master/packages/pluginutils/CHANGELOG.md#v410
- this is the same as the code in `normalize.ts` but it uses constants
from Node and is used by multiple Rollup plugins, so just helps with
standardization
- also less code and types to ship in the bundle!
- removed the dist files for `normalize` as well, but didn't do a build
in this commit as those are usually done in separate commits
On Windows the normalized paths in resolveId end up in POSIX format.
This cause rollup to treat the returned path as a new piece of content.
This in turn results in duplicate output for references across entry points.
Fixed by normalizing the path to use host OS separators before returning.
- previously, declarationDir was set to cwd if useTsconfigDeclarationDir
wasn't true, however, declarations aren't output to cwd, but to
Rollup's output destination, so this was incorrect
- instead, don't set declarationDir, which defaults it to outDir,
which is currently set to a placeholder
- previously, it rewrote declarations to output to Rollup's dest
from cwd, now rewrite from outDir placeholder instead
- and add a rewrite of sources to match relative path from Rollup's
output dest instead of outDir placeholder
- also change the one line in the docs that says it'll be
`process.cwd()`; every other reference says it'll be the output dest
