Enable three unicorn rules — one correctness, two performance — and fix every
existing violation repo-wide so the rules pass as errors.
prefer-number-properties (76 sites)
- parseInt/parseFloat/NaN -> Number.* : safe aliases (autofixed).
- isNaN -> Number.isNaN (12 sites, hand-converted): global isNaN coerces its
argument, Number.isNaN does not. Verified every call site already passes a
number (Number.parseInt results, number-typed fields, Date.getTime()), so the
conversion is behavior-preserving today and guards against a future non-numeric
argument silently coercing.
prefer-array-find (26 sites)
- .filter(pred)[0] -> .find(pred); .filter(pred).at(-1) / .pop() -> .findLast(pred).
Drops the intermediate array and short-circuits.
prefer-array-index-of (5 sites)
- .findIndex(x => x === v) -> .indexOf(v).
Verified: typecheck (node/cli/web) clean, 53 affected suites pass (1679 tests),
oxlint clean repo-wide. mobile/ uses findLast safely (already ships ES2023
.toReversed()); config scripts and e2e helpers run on Node 24.
* chore(lint): upgrade oxlint to 1.71 and enable 7 new rules
Upgrade oxlint 1.67.0 -> 1.71.0 (1.72 was blocked by the repo's 3-day
minimum-release-age supply-chain guard; nothing here needs it). The
bump is a no-op on the existing config.
Enable 3 error rules (backlog autofixed to zero in this commit) and
4 warn rules (surface signal without gating CI):
error (autofixed, behavior-preserving):
- unicorn/prefer-node-protocol (~1531 sites: bare builtin -> node:)
- typescript/no-import-type-side-effects (~36: all-inline-type -> import type)
- unicorn/no-array-reverse (19: copy-then-reverse -> toReversed)
warn (real signal, current fires are test-only/correct):
- unicorn/no-array-fill-with-reference-type (aliasing footgun guard)
- typescript/no-unsafe-function-type (bans bare Function type)
- unicorn/prefer-array-flat-map (map().flat() -> flatMap())
- unicorn/prefer-regexp-test (.match() in bool ctx -> .test())
mobile/.oxlintrc.json extends root, so it inherits all 7; the autofix
ran from root and covered mobile/ too.
Verification (all green): oxlint 0 errors (root+mobile+aux configs),
oxfmt clean, typecheck (node+cli+web), vitest 22795 passed / 0 failed,
builds (electron-vite + web + cli) succeed. node: rewrites confirmed to
skip embedded SSH/CLI string payloads (AST-only); all toReversed sites
verified to operate on fresh copies or write-once locals.
* chore(lint): bump mobile oxlint to 1.71 so inherited rules parse
mobile/ is a standalone pnpm project pinning its own oxlint@1.67, which
lacks unicorn/no-array-fill-with-reference-type (needs >=1.70). Since
mobile/.oxlintrc.json extends the root config, mobile CI's 'cd mobile &&
oxlint' failed to parse the new rule. Bump mobile to match root (1.71).
Verified in mobile/: oxlint 0 errors, oxfmt --check clean, tsc --noEmit
pass, vitest 978 passed / 0 failed.
