Good ESM/NodeNext migration and Vitest port. The main risks are CI fragility on windows-2019 with Node 20, and outdated GitHub Actions versions. Inline ESLint suppressions should be replaced with resolver config. Tests import .ts extensions under NodeNext; add allowImportingTsExtensions or switch to .js imports to avoid future breakage. Minor style nit: prefer node: prefixes for core modules in src.

.github/workflows/node-windows.yml:16-16
Node 20 isn’t guaranteed on thewindows-2019runner, which is deprecated. This can cause CI failures or unexpected Node versions. Preferwindows-2022(orwindows-latest) where Node 20 is available and supported. -

compileris assigned but never declared. Even though this test is skipped, leaving undeclared globals can lead to brittle tests and accidental regressions if the skip is removed later. It also risks leaking a global in Node.
Summary of changes
- Migrate project to ESM-only and Node 20.19.0+.
- Switch TypeScript to NodeNext/ES2022 with verbatim module syntax; update imports to include
.jsin source. - Replace AVA/NYC/Codecov with Vitest; add AVA-compat shim; port tests to TypeScript with snapshots.
- Add vitest config; adjust tsconfig base; remove legacy configs; rename ESLint/Prettier/Commitlint to
.cjs. - Update CI workflows to run Node 20.19.0 and use
vitest run. - Update README and package.json (exports map, engines, scripts, dev deps).

- Inline ESLint suppressions for import resolution in
src/point to missing NodeNext resolver config; remove disables and configure the resolver. - Tests import
.tsspecifiers directly; either enableallowImportingTsExtensionsor switch to.jsimports to avoid NodeNext/tsserver friction. - Two skipped watch-mode tests still assign to an undeclared
compiler, which will be a strict-mode ReferenceError when unskipped. - CI workflows use deprecated
windows-2019and v1 GitHub Actions; upgrade runners and actions versions. Also,lint-stagedignores.tsfiles and the lint script has a duplicate--cache.

Maintainability |
.github/workflows/validate.yml:22-22
Workflows still useactions/checkout@v1andactions/setup-node@v1. These are long out of date and miss security/perf improvements and native caching. Given the Node 20 baseline, bumping actions is appropriate. -

To avoid future friction with.tsimport specifiers in tests, you can also explicitly allow them in the compiler config (alternative to updating imports).
Summary of changes
- Migrated project to ESM-only with Node 20.19.0+ and updated exports map.
- Switched TypeScript to NodeNext/ES2022 with verbatimModuleSyntax and added type-only imports.
- Replaced AVA with Vitest; added AVA-compat shim; ported tests to TypeScript with snapshots under .snapshots.
- Updated CI workflows to Node 20.19.0 and tests to

- Adjusted internal imports to include

Same issue: inline resolver suppressions are a code smell. Configure ESLint to resolve NodeNext and drop the per-line eslint-disable comments.
Suggestion
After configuring the ESLint import resolver for Node/TypeScript as suggested earlier, remove the // eslint-disable-next-line import/no-unresolved lines and keep the .js import specifiers. Reply with "@CharlieHelps yes please" and I�ll send a commit to do this cleanup.

Compatibility |
.github/workflows/node-windows.yml:16-17
The Windows workflow still targets the deprecatedwindows-2019runner. GitHub removed this image (see runner-images deprecation), which will cause CI instability for a Node 20 baseline. Please move to a supported image, e.g.windows-2022(orwindows-latest). Also consider upgrading Actions to current major versions for security and performance. -
Maintainability |
.github/workflows/validate.yml:22-22
Bothactions/checkout@v1andactions/setup-node@v1are long out of date. Sticking with v1 misses important bug fixes, security patches, and native caching support for pnpm. Since you’re already standardizing on Node 20, it’s a good time to upgrade Actions as well. -
Maintainability |
.github/workflows/validate.yml:22-22
The validate workflow still usesactions/checkout@v1andactions/setup-node@v1, and the trigger ison: pushto all branches. On PRs, this can double-run (push + pull_request) and wastes CI minutes. -
Maintainability |
tsconfig.base.json:5-5
Tests directly import.tsfiles (e.g.,../../src/index.ts,../helpers/*.ts) undermodule: NodeNextwithverbatimModuleSyntax. This will keep working only if the toolchain transpiles on the fly, but TypeScript/tsserver will complain about.tsextensions unless explicitly allowed. This friction shows up in editors and future TS bumps. -

TheFileDescriptorinterface uses wrapper types (Boolean) instead of the primitiveboolean. This is discouraged in TypeScript, can surprise consumers at runtime, and is inconsistent with typical boolean usage. -

Summary of changes

- Add eslint-import-resolver-typescript and configure ESLint for NodeNext-style resolution; rename configs to .cjs.
- Update CI workflows to Node 20.19.0 and run Vitest; remove coverage workflow.
- Update README for ESM usage and Node 20 requirements.
- Convert internal imports to explicit
.jsspecifiers and add type-only imports in source. - Various test helper rewrites (MockCopyPlugin, integration/unit helpers, webpack version helpers).

- Two watch-mode tests don’t assign the watcher handle, so the teardown won’t close it when un-skipped—this risks leaking processes in CI. Fix by assigning the result of
watch(...)tocompiler. FileDescriptoruses wrapperBooleaninstead of primitivebooleaninsrc/helpers.ts.- Tooling gaps:
lint-stagedignores TypeScript files andlint:jshas a redundant flag; consider adding a top-leveltypesinpackage.jsonfor wider TS tooling compatibility. tsconfig.eslint.jsoninclude glob./*jslooks incorrect; use./*.{js,cjs,mjs}instead to ensure ESLint sees root-level JS configs.

FileDescriptoruses wrapper types (Boolean) instead of the primitiveboolean. This is discouraged in TypeScript and can lead to surprising runtime behaviors (e.g., truthiness differences) and inconsistent typings. Prefer the primitivebooleanfor flags. -

For broader TypeScript tooling compatibility, consider adding a top-level"types"field pointing to your declaration file. While theexportsmap includes atypesentry, some tooling still expects the top-leveltypes. -
