chore: migrate to ESLint 10 flat config#59
Merged
Conversation
Replaces .eslintrc.js with eslint.config.mjs, preserving every rule and severity from the legacy config. Toolchain bumps required by the migration: - eslint 8.57 -> 10.x - @typescript-eslint/eslint-plugin + parser 6.x -> 8.x - eslint-plugin-jest 27 -> 29 - eslint-config-prettier 9 -> 10 - eslint-plugin-import (ESLint 9 max) replaced by eslint-plugin-import-x, registered under the same "import" rule namespace Closes #35 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Supersedes the Dependabot PR, which could not rebase after the lockfile regeneration in #59. TypeScript 6.0 required two tsconfig.spec.json fixes: - module 'commonjs' + moduleResolution 'node': the legacy node10 resolution was removed in TS 6; switched to module 'node20' (matching the jsii 6-generated tsconfig). - baseUrl: hard-deprecated in TS 6 (TS5101); removed, with the paths alias made explicitly relative. - types: TS 6 no longer auto-includes @types packages under this setup; declared ['jest', 'node'] explicitly. Previously ts-jest swallowed the TS5101 config error and silently compiled without types. Verified: tsc -p tsconfig.spec.json clean, 34/34 tests, jsii build clean, lint clean.

Migrates the lint setup from legacy
.eslintrc.jsto flat config (eslint.config.mjs), preserving every rule and severity 1:1.Toolchain changes
importrule namespace, so all rule names and anyeslint-disablecomments keep working unchanged.typescript-eslintmeta package (flat-config API),@eslint/js,globals.The lockfile was regenerated from scratch (the incremental upgrade hit ERESOLVE against the old tree), hence the large lock diff.
Verification
npm run lint: 0 errors (13 pre-existing warnings, same severities as before)npm run build(jsii): cleannpm test: 34/34npm run format:check: cleanCloses #35. Dependabot should auto-resolve #9, #14, and #16 once this merges. This also unblocks re-testing #13 (TS 6), since typescript-eslint 8.60 supports TypeScript <6.1.
