## Repository: `BYK/superset`

**This is NOT Apache Superset** (the data exploration platform). This is **`superset`** — a small **JavaScript/Node.js library** by Burak Yigit Kaya that extends the ES6 `Set` class with functional methods like `map()`, `filter()`, `reduce()`, `union()`, `isSubsetOf()`, etc. Published on npm as `superset`.

### Structure Summary

| Aspect | Details |
|---|---|
| **Git remote** | `https://github.com/BYK/superset.git` |
| **Language** | JavaScript (Node.js ≥ 4.0.0) |
| **Monorepo?** | **No** — single-package repo. No `lerna.json`, `pnpm-workspace.yaml`, or `workspaces` field. |
| **Package manager** | **Yarn** (v1 classic — `yarn.lock` present at root, no `.yarnrc.yml`) |
| **Entry point** | `index.js` (305 lines, single-file library) |

### Dependency Files

| File | Purpose |
|---|---|
| `package.json` | Only file. ...

3: ## Summary
4: 
5: - **0 security advisories** (repo-level)
6: - **18 open Dependabot alerts** — all from stale `yarn.lock` referencing ancient transitive dependencies
7: - The devDependency modernization in `package.json` is **already done** in the working tree (uncommitted)
8: - The old `yarn.lock` is deleted but no `pnpm-lock.yaml` exists yet
9: 
10: ## Root Cause
11: 
12: All 18 alerts reference packages in the **stale `yarn.lock`** file. The working tree already has:
13: - ✅ `package.json` modernized (pnpm, eslint 9, c8, mocha 11, modern remark)
14: - ✅ `eslint.config.mjs` created (flat config replacing `.eslintrc.yml`)
15: - ✅ `.remarkrc.mjs` created (replacing `.remarkrc`)
16: - ✅ `test/superset.spec.js` updated (dirty-chai removed, assertions fixed)
17: - ✅ `.github/workflows/build.yml` updated (pnpm, Node ...

f5deefb fix: resolve all 18 Dependabot security alerts
4b61671 Bump lodash from 4.17.21 to 4.17.23 (#24)
4977b55 Bump semver from 5.4.1 to 5.7.2 (#22)

fix: resolve all 18 Dependabot security alerts

Nuke and rebuild all devDependencies with modern equivalents:

- Replace istanbul with c8 for V8-native code coverage
- Replace coveralls npm package with getsentry/codecov-action GH Action
- Replace eslint@2 with eslint@9 + @stylistic/eslint-plugin (flat config)
- Replace mocha@2 with mocha@11
- Replace chai@3 + dirty-chai with chai@4.5 (no plugin needed)
- Replace remark@4 with remark-cli@12 + modern lint presets
- Remove coveralls, dirty-chai, istanbul, eslint-plugin-markdown

Package manager migration:
- Switch from yarn v1 to pnpm@10.28 with pnpm-lock.yaml
- Add pnpm overrides for mocha transitive deps (serialize-javascript, diff)

CI modernization:
- Update Node test matrix from 10/12 to 20/22
- Update all GH Actions to v4
- Add pnpm/action-setup@v4 with caching
- Add dedicated coverage upload job with getsentry/codecov-action

Config migrations:
- .eslintrc.yml -> eslint.config.mjs (ESLint 9 flat config)
- .remarkrc -> ...
