fix(lint): clean up oxlint migration follow-ups - #473
Conversation
Addresses code-review findings on the oxlint migration: - Drop dangling eslint-disable comments left after the oxlint-disable comments were added (unused once oxlint-disable takes effect). - Encode the codespaces import exception directly in the no-restricted-paths zones instead of suppressing it at each call site. - Replace the hand-rolled Node-builtin-import detection in local-rules/node-imports with oxlint's native import/no-nodejs-modules (matching allow-list shape), keeping the custom rule only for the unconditional `path` ban that no-nodejs-modules can't express. - Harden src/renderers/client/tsconfig.json with noEmit: true, since its rootDir/outDir/include no longer agree (rootDir was widened to admit a sibling-directory import) and the file is IDE-only. Verified via `oxlint src`, `tsc --noEmit`, and the full unit test suite against a diff of before/after lint output.

Block the node:path specifier.
isBuiltin('node:path') returns true, but name === 'path' does not report it. Add static import, dynamic import, and require() fixtures.

Fixed in a5c61a0. reportIfPath now matches path and node:path; since the ban is on two exact specifiers, the redundant isBuiltin() call is gone.
Verified with a .node.ts fixture covering static import, re-export, export *, require(), and dynamic import() for each specifier — all eight report. No node:path imports exist in src/, so npm run lint is still at 0 errors. Please resolve the thread if this looks right.

isBuiltin('node:path') is true, but the `name === 'path'` guard meant the
prefixed specifier slipped through every import form. Since the ban is on
two exact specifiers, drop the redundant isBuiltin() call and match both.
Verified against a fixture covering static import, re-export, `export *`,
require(), and dynamic import for each of `path` and `node:path`: all eight
now report.

The task ran the `lint` npm script, which is `oxlint src` with no `--format`. Oxlint then emits its graphical report, which `$oxlint` cannot parse, so the Problems panel stayed empty. Run oxlint directly with `--format=agent` instead of adding the flag to the npm script, so CI's `npm run lint` keeps oxlint's automatic GitHub-annotation output. Also make the colon after the severity optional in the matcher pattern. Lint diagnostics print `error local-rules(node-imports): ...`, but parse errors print `error: Unexpected token` — the old pattern silently dropped the latter.

`npx oxlint` falls back to fetching an unpinned oxlint from the registry when the local binary is missing. `npm exec --no` resolves only the local install and fails otherwise. Carried over from PR #473, which merged before this commit landed on it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_013NiSxDXjAh15TKkGjn3rj9
* build(lint): port ESLint config to oxlint Faithful port of .eslintrc.cjs's 21 active rules to oxlint.config.mts, run alongside ESLint for now (both `npm run lint` and `npm run lint:oxlint` are green). Mirrors deepnote-internal PR #20639. - Native rules (ban-ts-comment, no-dupe-class-members, no-explicit-any, no-restricted-imports, no-unused-vars, no-use-before-define, no-useless-constructor, no-void, no-labels, no-with, jsx-filename-extension) map straight onto oxlint's built-ins. - no-floating-promises now runs type-aware via tsgolint instead of ESLint's parserOptions.project (the sole reason for that option). - import/no-restricted-paths (the 12 architecture-layering zones) runs through the real eslint-plugin-import as a jsPlugin, aliased to import-plugin since oxlint reserves the `import` plugin name. eslint-plugin-import is bumped to latest v2 for ESLint-9 API compat, which the jsPlugin runtime requires. - build/eslint-rules/index.js (the 4 custom architecture rules) is modernized in place for the same ESLint-9-shaped runtime: context.getFilename() -> context.filename, 2-arg context.report() -> object form, and the node-builtin check now uses node:module's isBuiltin instead of eslint-plugin-import's internals. Added local-rules/no-for-in, since oxlint has no equivalent to no-restricted-syntax (that rule relied on ESLint's esquery selectors, which can't run via jsPlugins) - the other two selectors it carried, LabeledStatement and WithStatement, map onto oxlint's native no-labels and no-with. - tsgolint requires a baseUrl-free, non-relative-paths-free tsconfig (typescript-go doesn't support `baseUrl`): root tsconfig.json drops `baseUrl` and switches `paths` to the `./types/*` form (supported without baseUrl since TS 4.1); src/renderers/client/tsconfig.json (IDE-only - esbuild bundles that entry point directly and never reads this file) gets the same treatment plus an explicit rootDir, since its import of a sibling directory made TS's inferred rootDir ambiguous. npm run typecheck stays green either way. Suppression comments: the 1092 existing eslint-disable comments are untouched - oxlint honours them natively, including normalizing the @typescript-eslint/ prefix to typescript/. Only the comments whose rule id is actually changing were touched, and since ESLint hard-errors on a disable comment naming a rule it doesn't recognize (while oxlint quietly ignores one it doesn't), each of those sites now carries both an unchanged eslint-disable comment for the old id and a new oxlint-disable-line/-next-line comment for the new one, so both tools stay green during the parallel-run window: - import/no-restricted-paths -> import-plugin/no-restricted-paths (8 sites, all still real zone violations). - no-restricted-syntax's ForInStatement selector -> local-rules/no-for-in (3 sites that are genuine for..in loops). The other 5 sites referencing no-restricted-syntax turned out to guard for..of loops, which that selector never matched in the first place (dead suppressions predating this migration) - the stale token is dropped rather than mapped to a rule that wouldn't fire there either. - The for..in sites use a comment inside the loop's parens rather than a trailing same-line comment, since Prettier unconditionally hoists a trailing comment after a block's opening brace onto its own line inside the block, which silently breaks the suppression. package.json also adds a lint:oxlint script (oxlint src) alongside the existing eslint-based lint script, and moves eslint-plugin-import to ^2.32.0. The eslint->oxlint script swap, CI wiring, and dependency removal land in a follow-up commit once the findings below are cleared. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NeHawfLMtvXn252EkCip2k * fix(lint): resolve floating-promise findings surfaced by oxlint tsgolint's no-floating-promises implements a check the old @typescript-eslint/eslint-plugin@6.9.0 didn't have: a bare array-of- Promises expression statement (e.g. `arr.map(x => asyncFn(x))` used without await/void) is now also flagged, not just a bare single Promise. This surfaced 8 sites, 1 of them a real bug: - emptyNotebookCellLanguageService.ts: `await emptyCodeCells.map(async cell => ...)` doesn't actually wait for the mapped promises - await on a plain array resolves immediately, it does not wait for the array's contents to settle. Fixed with Promise.all so the language update genuinely completes before chainWithPendingUpdates' callback resolves. - The other 7 (events.ts, remoteKernelFinderController.ts, localPythonEnvKernelSourceSelector.node.ts, and 4 sites in executionService.vscode.test.ts) are intentional fire-and-forget: each promise in the array already has its own .catch(noop)/.then(noop, noop), so nothing goes unhandled - the array itself was just never meant to be awaited. Marked with `void`, the same convention the ported no-floating-promises config already used for this (ignoreVoid: true). Verified with the full unit test suite (2545 passing) and npm run typecheck; `npx oxlint src` is now clean except for 27 pre-existing warn-level no-unused-vars findings on unused catch parameters (unused-catch-var support the old @typescript-eslint/no-unused-vars@6.9.0 apparently never enforced either, despite matching config) - warn severities don't fail CI, matching prior behavior, so those are left as-is; flagged separately for whoever picks this up next. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NeHawfLMtvXn252EkCip2k * build(lint): delete ESLint `npm run lint` now runs oxlint directly (~5-7s vs the old 47s baseline); lint-staged and the CI lint step follow. Removes the 14 now-unused eslint packages (eslint itself, @typescript-eslint/{parser,eslint-plugin, eslint-plugin-tslint}, eslint-config-{airbnb,prettier}, and eslint-plugin- {header,jsdoc,jsx-a11y,no-null,prefer-arrow,prettier,react,react-hooks}), keeping eslint-plugin-import, eslint-plugin-local-rules and eslint-plugin- no-only-tests since oxlint's config still runs them as jsPlugins. Editor/devcontainer/docs recommendations move from dbaeumer.vscode-eslint to oxc.oxc-vscode (the reference deepnote-internal PR skipped this; verified oxc.oxc-vscode and the source.fixAll.oxc code-action id against oxc-project's own docs). tasks.json's npm-lint task also drops the $eslint-stylish problem matcher (oxlint's output isn't in that format) and its detail text, which was already stale (referenced a `.eslintrc.js` that never existed here - the file was always `.eslintrc.cjs`). Removing the 14 packages required a fresh npm install, which surfaced an unrelated latent bug: src/test/interpreters/condaService.node.ts (test- only fixture code, not part of the shipped extension) imports `untildify` without ever declaring it - it only resolved because untildify happened to be hoisted to the top level as a transitive dependency of an unrelated package (default-browser-id, via @vscode/vsce). That package no longer needs untildify after this dependency churn, so the phantom import broke `npm run typecheck`. Declared explicitly as a devDependency, pinned to the 4.0.0 that was already the resolved (if undeclared) version. Verified: npm run typecheck, npm run lint (oxlint, clean except the 27 pre-existing warn-level findings noted in the prior commit), npm run format, npm ci (matching the CI install step exactly), and the full unit test suite (2545 passing) all green. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NeHawfLMtvXn252EkCip2k * fix(lint): restore node-imports coverage for re-exports and dynamic imports Porting `node-imports` off `eslint-module-utils/moduleVisitor` kept only two of the five AST node types that visitor subscribed to. `ExportNamedDeclaration`, `ExportAllDeclaration` and `ImportExpression` were dropped, so in web/shared code (anything not `.node.ts`, `.test.ts`, or under `src/test`) these forms stopped being checked entirely: export * from 'fs' export { readFile } from 'node:fs' await import('child_process') The gap is not theoretical. `src/platform/common/crypto.ts:34` already does `await import('node:crypto')` behind an `eslint-disable-next-line local-rules/node-imports` comment that predates the oxlint migration — proof the rule used to fire there. Since the port, the rule could not see that line at all, leaving the suppression comment inert and the web/node boundary (specs/architecture.md) unenforced for every one of these forms going forward. Restores the three missing visitor keys. `checkSource` guards on `node.source` because `export { x }` and `export const x = 1` are `ExportNamedDeclaration` nodes with a null source; `ImportExpression` checks for a string literal so `import(someVariable)` is skipped rather than crashing. oxlint 1.77.0's jsPlugin runtime supports all three keys directly, so no CallExpression fallback is needed for dynamic imports. Verified: each of the three restored forms plus the `import`/`require` controls reports exactly once (no double-firing); `export { x }` reports nothing and does not throw; stripping crypto.ts's disable comment now produces the expected error and restoring it suppresses again; and full `npm run lint` is unchanged at exit 0 with 0 errors and the same 27 pre-existing no-unused-vars warnings. `npm run typecheck` and `npm run format` green.

It carries the useful message (naming vscode-path) and, unlike the native rule, stays enabled in .node.ts/.test.ts, where the ban still applies.

Summary
Follow-up fixes from a code review of #468 (oxlint migration):
eslint-disable-next-line import/no-restricted-pathscomments left over at every site where anoxlint-disable-linecomment was already added — they were harmless today but would start failing the build under--report-unused-disable-directives.codespacesimport exception directly in theno-restricted-pathszones (oxlint.config.mts) instead of suppressing it at each of the 5 call sites individually.local-rules/node-importswith oxlint's nativeimport/no-nodejs-modules(same{ allow: [...] }option shape), with per-file overrides for.node.ts/.test.ts/src/test/**mirroring the old behavior. The custom rule now only keeps the unconditionalpath-import ban, whichno-nodejs-modulescan't express (it needs to still fire inside.node.tsfiles).src/renderers/client/tsconfig.jsonwithnoEmit: true. ItsrootDirwas deliberately widened in the migration (to admit a sibling-directory import, per that commit's message) butoutDir/includeweren't adjusted to match; the file is IDE-only today (esbuild bundles the actual output, andtypecheckonly runstsc -p ./ --noEmiton the root config), so this just makes that permanent rather than reverting the original fix.Not changed:
