[2.2.3] - 2026-02-08

2.2.12

Patch Changes

  • #364 86baa02 Thanks @ofri-peretz! - Add the ecosystem and oxlint marks to the README logo row. Each plugin now leads with Interlace -> its ecosystem (node, nestjs, express, react, mongodb, postgresql, mysql, sqlite, prisma, drizzle, knex, typeorm, sequelize, lambda, vercel, jwt) -> oxlint -> ESLint; the generic quality plugins carry the row without an ecosystem mark. README-only change - no rule behaviour is affected. The patch bump is what carries the new README onto npm, which only refreshes a package README on publish.

2.2.11

Patch Changes

  • #358 1b8c0df Thanks @ofri-peretz! - Fix SDK peer declarations that npm silently ignored

    Seven plugins listed their target SDKs under peerDependenciesMeta with {"optional": true} but never declared them in peerDependencies. npm drops any peerDependenciesMeta entry that has no matching peerDependencies key, so the metadata was inert — these packages effectively declared no SDK peer at all. Nothing warned: the failure mode of a dependency you never declared is silence.

    Each SDK now appears in both maps, matching the shape eslint-plugin-pg and eslint-plugin-mongodb-security already use — a supported major range in peerDependencies, optional: true in peerDependenciesMeta:

    PluginSDKRange
    express-securityexpress^4.0.0 || ^5.0.0
    helmet^6.0.0 || ^7.0.0 || ^8.0.0

    class-validator^0.14.0 || ^0.15.0
    class-transformer^0.5.0
    react-featurestypescript>=4.8.4
    vercel-ai-securityai^4.0.0 || ^5.0.0 || ^6.0.0 || ^7.0.0

    Ranges were taken from each SDK's real release history, bounded below by the oldest major whose call shape the rules still match and above by the current major. cors, csurf, class-transformer and @aws-sdk/client-lambda have only ever shipped one usable major. The ai range spans v4 because require-max-steps deliberately accepts both the v4 maxSteps option and the v5+ stopWhen form. The two typescript entries reuse the >=4.8.4 bound @interlace/eslint-devkit already declares, since these are the same type-aware-graceful rules behind the same optional TS program.

    Every range admits the version this repo's __compatibility__ specs are actually tested against, so the declaration cannot drift from what CI proves.

    Nothing to migrate. Every entry stays optional, so no install adds a package or emits a warning when the SDK is absent. What changes is that a consumer on an unsupported major now gets a peer warning instead of nothing — which was the point of the metadata in the first place.

    • @interlace/eslint-devkit@1.7.0

2.2.10

Patch Changes

  • #338 dc25c81 Thanks @ofri-peretz! - Re-publish every package so npm carries the optimised artifact

    No source changed. This is a no-op patch whose entire purpose is to ship the artifact the current build already produces.

    Manifests. scripts and devDependencies are now stripped from every published package.json. Neither can do anything in a consumer’s node_modules — npm never runs one and never installs the other — but they shipped in all 27 manifests, cluttered the npm page, and were read by SCA tools scanning installed manifests. No package declares a lifecycle hook, so nothing observable changes. Every published package is bumped so this applies uniformly rather than to a subset.

    Tarballs. 20 packages were last published before the build pipeline changed and still ship AGENTS.md, CHANGELOG.md, JSDoc in the emitted .js, and the full generated .d.ts tree:

    eslint-plugin-drizzle-security52 kB19 kB−33 kB
    eslint-plugin-knex-security51 kB19 kB−32 kB
    eslint-plugin-modernization45 kB38 kB−7 kB

    Those 20 go from 3428 kB to 2169 kB — −36.7%. The remaining 7 were released after the pipeline change and only gain the manifest strip.

    A new check in scripts/check-published-artifacts.ts fails the build if scripts or devDependencies ever reappear in a published manifest, so the strip cannot silently regress.

    The dependency ranges did not need updating: every plugin pins @interlace/eslint-devkit with a caret that 1.6.0 satisfies, verified by a clean install of an unchanged plugin resolving devkit 1.6.0 with zero dependencies and no typescript in the tree.

    • @interlace/eslint-devkit@1.6.1

2.2.9

Patch Changes

  • #294 659f6dc Thanks @ofri-peretz! - Rewrite description and keywords on every published package for npm search discovery. npm ranks on name, description, and keywords, and the registry only picks up these fields at publish — so this is metadata-only and takes effect for each package on its next release.

    Descriptions now lead with the search phrase. Every one starts ESLint plugin for <the thing you'd search> instead of a brand-first or category-first framing, and names the concrete vulnerabilities the plugin actually detects. Three were corrected while doing so:

    • eslint-plugin-import-next claimed "100x faster no-cycle detection". No 100x measurement exists: CLAIMS.md records 3.1x end-to-end (8x in pure rule execution) on a 5,483-file React codebase, and the highest number in any benchmark result is 54.9x on the synthetic corpus. The description now states the real-codebase figure.
    • eslint-plugin-secure-coding claimed SQL injection, XSS and CSRF coverage — none of which are its rules. It now names what it does detect: LDAP, XPath, XXE, GraphQL and template injection, unsafe deserialization, ReDoS, missing authentication, and PII in logs.
    • eslint-plugin-secure-coding ("89 rules") and eslint-plugin-react-a11y ("37 rules") hard-coded rule counts that had drifted from reality. Counts are generated into interlace-numbers.json; hand-typed copies are removed rather than corrected.

    Keywords now match the vocabulary of the plugins that rank. eslint-plugin-security, eslint-plugin-jsx-a11y, eslint-plugin-n and eslint-plugin-import all carry the eslint / eslintplugin / eslint-plugin trio — six of our packages were missing eslintplugin, and every one now carries all three plus static-analysis, linting and code-quality. Security plugins add sast, appsec and vulnerability; node-security and secure-coding also carry nodesecurity, the exact keyword eslint-plugin-security ranks on. Each plugin gained the CWE identifiers and attack names for what it detects (cwe-78 command injection, cwe-22 path traversal, cwe-89 SQL injection, cwe-79 XSS, cwe-347 JWT algorithm confusion, cwe-352 CSRF, cwe-943 NoSQL injection), and node-security gained the crypto vocabulary it had been missing entirely despite absorbing the crypto rule set (crypto, cryptography, weak-hash, md5, sha1, timing-attack).

    No rule behavior, exports, or configuration changes.

  • Updated dependencies [e1cdf83, 659f6dc]:

    • @interlace/eslint-devkit@1.4.3

2.2.8

Patch Changes

  • #269 7028fe2 Thanks @ofri-peretz! - docs: dual-logo README header (Interlace mark + ESLint mark side by side) and closing Interlace footer — refreshes the README rendered on npmjs.com. No runtime changes.

  • Updated dependencies [7028fe2]:

    • @interlace/eslint-devkit@1.4.2

2.2.7

Patch Changes

  • #252 d67e395 Thanks @ofri-peretz! - Fix Codecov badge showing "unknown" — switch from flag to component URL format

2.2.6

Patch Changes

  • #225 34ff5a8 Thanks @ofri-peretz! - CI-only: pin all coverage thresholds at 100% (integration target, merges last).

2.2.5

Patch Changes

  • #213 391dbe6 Thanks @ofri-peretz! - Align every security rule's meta.docs.cvss to the CVSS its finding actually emits. The emitted machine-readable message sources its CVSS:x from CWE_MAPPING via formatLLMMessageenrichFromCWE, but the static meta.docs.cvss documentation field had drifted on 45 rules across these 7 plugins — e.g. no-hardcoded-credentials documented 9.5 while emitting CVSS:9.8 (the value the published article and SARIF/LLM consumers already read).

    This corrects the documentation metadata only — no emitted finding changes. Locked by security-cvss-docs-consistency.lock.test.ts (cross-plugin: every security rule's meta.docs.cvss must equal the CVSS it emits), the no-hardcoded-credentials rule lock (real ESLint Linter emission), and a devkit enrichFromCWE contract test pinning CWE-798 → 9.8.

    Follow-up (not in scope): 50 security rules document a CVSS that never appears in any emitted message (their messages carry no CWE), and several rules emit the generic CWE score where a rule-specific score may be warranted — both change emitted output and are separate decisions.

2.2.4

Patch Changes

  • #143 213cde1 Thanks @ofri-peretz! - fix(no-missing-null-checks): eliminate 53 false positives via three new narrowing patterns

    Rules that were recognized as null guards are now correctly identified as safe:

    1. Truthy if guardif (obj) { obj.prop } — direct truthy check proves non-null. Also covers chains: if (response) protects response.data.items.
    2. Short-circuit ANDobj && obj.prop — right side of && only runs when left is truthy.
    3. Ternary consequentobj ? obj.prop : fallback — truthy test guards the consequent.

    Also: bumped beforeAll timeout to 30 seconds in 7 compatibility test files (__compatibility__/*.spec.ts). Native-addon packages routinely exceed the previous 10-second default on a cold ESM load.
