Pull request overview
This PR migrates the repository’s Node-based build/lint/helper scripts under scripts/ from CommonJS to ESM without changing the root package to "type": "module", by introducing a nested scripts/package.json module scope. This aligns the scripts with the typescript/no-require-imports lint rule and simplifies the lint configuration accordingly.
Changes:
- Add
scripts/package.jsonwith"type": "module"to scope ESM toscripts/only. - Mechanically convert
scripts/**/*.jsandscripts/lib/**/*.jsfromrequire/module.exportstoimport/export, including ESM entrypoint guards and relative.jsspecifiers. - Update lint config and npm
clear-cachescript to reflect ESM usage.

📝 WalkthroughWalkthroughThe scripts package is now configured as ESM. Script imports, exports, path resolution, entry-point checks, and the ChangesScripts ESM migration
Estimated code review effort: 3 (Moderate) | ~30 minutes Merge Risk: 🔵 Low · up to The ESM migration leaves two error handlers vulnerable to masking failures and two scripts vulnerable to import-time errors when no entry-script path is present. The PR is mergeable with explicit owner awareness and follow-up to normalize rejection values and guard process.argv[1]. Possibly related PRs

In `@scripts/lint-any.js`:
- Line 544: Update the error handler containing the “Unexpected error” log to
stringify the unknown rejection value with String(error) instead of accessing
error.message, matching the sibling lint scripts and ensuring null or undefined
errors do not mask the original failure.
Apply the same fix in `@scripts/jenkins-status.js` around lines 158 - 163: The
same unknown rejection value is read through .message in this handler.
In `@scripts/manage-mailpit.js`:
- Around line 756-758: Guard process.argv[1] before passing it to pathToFileURL
in the entry-point checks for scripts/manage-mailpit.js lines 756-758 and
scripts/stop-dev-services.js lines 266-268, so imported modules do not throw
during evaluation; retain the existing self-execution behavior when an entry
script is present.

Surfaced by staging every script at once: pre-commit lints only staged files, so these never blocked a commit before. - void the entry-point promise calls (no-void is off for scripts/) - String(error) in catch-block template literals - annotate .catch rejection params as unknown via JSDoc - Reflect.deleteProperty instead of a computed delete - Object.assign instead of spreading caller-supplied options, with the conflicting prefer-object-spread warning disabled inline - hoist the synchronous frontend linters out of Promise.all, which never awaited them and made the adjacent concurrency comment inaccurate

- add scripts/package.json with type:module so only scripts/ switches module system, leaving web/wwwroot browser files untouched - require -> import across 34 files, module.exports -> named exports - __dirname -> import.meta.dirname, require.resolve -> import.meta.resolve via fileURLToPath, require.main -> import.meta.url comparison - guard process.argv[1] in the entry-point checks, since it is undefined when a module is imported without an entry script and pathToFileURL then throws during evaluation - import fs and path in launch-find-viper, which referenced both without importing them and so threw whenever it found the process - drop the obsolete CommonJS lint exemptions, including the no-require-imports one added on the parent branch - delete scripts/.eslintrc.js, dead since eslint moved to flat config

Converts
scripts/from CommonJS to ESM.Why.
typescript/no-require-importsfires on every file inscripts/. #309 silenced it, sinceimport/no-commonjsandunicorn/prefer-modulewere already off. This follows the rule instead: four fewer suppressions, andscripts/matches the rest of the repo (VueApp,eslint.config.mjs,vite.config.tsare already ESM).Scope. Root
package.jsonhas no"type"field, so setting it there would flip theweb/wwwroot/js/*.jsbrowser files too. A nestedscripts/package.jsonwith{"type": "module"}confines the change toscripts/.The first commit fixes pre-existing oxlint errors in
scripts/, kept separate so the migration stays reviewable.Hand-worked cases (the rest is mechanical
require→importacross 34 files):__dirname(21)import.meta.dirnamerequire.main === module(2)process.argv[1] && import.meta.url === pathToFileURL(...).href. The guard matters becauseprocess.argv[1]is undefined when a module is imported without an entry script, andclear-cachenow does exactly thatrequire.resolve(1)import.meta.resolve+fileURLToPathscripts/.eslintrc.jsAlso fixes a pre-existing bug found in review:
launch-find-viper.jsusedfsandpathwithout importing them.
