feat(heureka): migrate ESLint config to vite-react-ts.mjs by hodanoori · Pull Request #1883 · cloudoperators/juno

hodanoori · 2026-08-11T13:48:42Z

Summary

Migrates the Heureka application from the legacy juno-typescript.mjs ESLint config to the new vite-react-ts.mjs configuration. The new config provides pure TypeScript linting rules without JavaScript rule interference, enabling strict type checking across the app. All 18+ legacy workaround rule overrides have been removed and replaced with real fixes. Part of the project-wide ESLint migration epic #1565.

Changes Made

Switch eslint.config.mjs to import vite-react-ts.mjs and remove all legacy rule workarounds
Add void operator to all fire-and-forget navigate() calls to satisfy no-floating-promises
Wrap async onClick handlers with void to fix no-misused-promises
Remove async from test loaders and act() callbacks that had no await (require-await); restore await act(async () => {...}) with a scoped disable for two Suspense-dependent tests where the async is required for React promise resolution
Replace issuesPromise && (...) with issuesPromise != null && (...) to fix no-misused-promises in boolean conditionals
Type queryClient.setQueriesData cache callbacks with a local cache shape type instead of any
Type getActiveVulnerabilityFilter and sanitizeFilterSettings with concrete types instead of any
Cast DateTime GraphQL scalar fields explicitly to fix no-unsafe-assignment
Fix getNormalizedError network error shape with an explicit type instead of any cast
Remove redundant string | "" union types in ComponentInstance (no-redundant-type-constituents)
Remove unnecessary as X type assertions in route validateSearch functions
Fix @ts-ignore → removed entirely in codegen.ts (dotenv has types)
Add /* eslint-disable */ header to auto-generated graphql.ts
Replace any in types/index.d.ts plugin options with Record<string, unknown>
Replace any in utils.ts utility functions (isEmpty, isNil, omit) with unknown
Fix ErrorBoundary resetKeys prop type from any to unknown[] and remove redundant !! cast
Add explicit React.MouseEvent / React.ChangeEvent / Date[] types to event handler callbacks where juno-ui-components prop types resolve as any in CI but correctly locally
Add scoped eslint-disable comments for useAuth() from greenhouse-auth-provider and encodeV2/decodeV2 from juno-url-state-provider — these packages export error-typed values in CI due to type resolution differences; each disable has an explanatory comment
Apply lint fixes to the new RemediationModal component introduced by a concurrent main branch refactor (same patterns: useAuth() cast, void handleConfirm(), typed input callbacks)
Add 2 justified rule overrides in eslint.config.mjs: react-refresh/only-export-components (TanStack Router requires mixed exports in route files) and react-hooks/set-state-in-effect (intentional derived-state sync pattern)
Set reportUnusedDisableDirectives: "off" to suppress false-positive warnings for CI-only disables that are unused locally (where package types resolve correctly)
Exclude vite.config.ts, vitest.config.ts, vitest.setup.ts, and tailwind.config.ts from ESLint entirely (not included in tsconfig.json, causing parse errors in type-aware linting)

Review Guide

Changes are mechanical and fall into 6 categories — reviewers can approve categories 2–5 at a glance and focus attention on 1 and 6:

Config & setup (eslint.config.mjs, package.json, vite-react-ts.mjs) — the actual migration; the only part worth careful review
void navigate(...) (~10 files) — fire-and-forget navigate() calls marked void; no behaviour change
async removal (~8 test files) — loader: async () => → loader: () => and act(async → act( where there was no await; no behaviour change. Two Suspense tests keep await act(async () => {...}) with a scoped lint disable.
Promise boolean guards (ImageIssuesList, ImageVersionIssuesList) — {promise && ...} → {promise != null && ...}; no behaviour change
Type tightening (utils.ts ×2, ErrorBoundary, getTestRouter, types/index.d.ts, event handler annotations) — any replaced with concrete types or explicit casts with comments
Typed cache callbacks (IssuesDataRow, RemediatedIssueDataRow, RemediationHistoryPanel, RemediationModal) — queryClient.setQueriesData callbacks now use a local RemediationsCache type instead of any; verify the shape matches what's actually stored in the cache

Pull request overview

Migrates the Heureka app to the new shared vite-react-ts.mjs ESLint flat-config and updates the app codebase to satisfy stricter type-aware TypeScript lint rules introduced by the migration.

Changes:

Switch apps/heureka/eslint.config.mjs to use @cloudoperators/juno-config/eslint/vite-react-ts.mjs and replace legacy rule workarounds with targeted, justified overrides.
Apply mechanical lint fixes across the app (e.g., void navigate(...), remove unnecessary async, tighten types / remove any, adjust promise guards).
Update Heureka devDependencies/lockfile and add a changeset documenting the migration.

This config still extends @eslint/js's recommended rules, which reintroduces JavaScript rule sets into what is described (in the PR/epic) as a “pure TypeScript” ESLint config. If the goal is to avoid JS/TS rule mixing, drop the JS recommended config here and rely on the TypeScript-ESLint presets instead.

if the linter is right and the refreshKey is not needed good to clean this up
