New Features

• --dashboard lists the largest code files. The Project section now ranks files by lines, with their tokens and size, next to the largest formats — the files worth splitting, beside the most complex ones further down. Only code is ranked: a lockfile, a changelog or a long HTML page is often the longest file in a repository and nothing anyone would refactor, so prose, data and markup files are left out, as they are from the complexity list. --summary-top sets the rows, and the json, markdown and html reporters carry the same list (project.largestFiles in jscpd-dashboard.json, an added key). See fixtures/dashboard-demo. (#​1086)

• basta now detects which frameworks a project uses. A framework runs files that nothing imports: a router's pages, a runtime's plugin directories, handlers it finds by convention. basta used to know three such cases, hard-coded: Nuxt, Nitro and WXT. It now reads them from a list of about fifty definitions built into the binary, frameworks.yaml. The list covers Next.js, Nuxt, Nitro, WXT, Plasmo, Remix, React Router, SvelteKit, Astro, SolidStart, TanStack Start, Qwik City, Gatsby, RedwoodJS, Angular, NestJS, AdonisJS, Sails, @fastify/autoload, Strapi, Medusa, Ember, Quasar, React Native, Expo, Cloudflare Workers, Vercel, Netlify, Serverless, Trigger.dev, Docusaurus, VitePress, Eleventy, Storybook, Histoire, Jest, Vitest, Mocha, AVA, Playwright, Cypress, Cucumber, Prisma, Knex, Sequelize, TypeORM, Hardhat and Create React App.

  • A framework counts as present when basta finds any one of three things: its config file, its package among the package.json dependencies, or its section in package.json. basta checks every directory that holds scanned files, so each package of a monorepo is treated as its own project.
  • Several frameworks can apply at once, and each one keeps its own files alive. A Next.js application with Storybook, Vitest and Prisma counts as four.
  • The files and directories a framework loads are matched relative to the directory where the framework was found. basta also reads the framework's config for the settings that move directories: srcDir, entrypointsDir, appDirectory, sourceRoot in nest-cli.json, and imports: false.
  • The console report lists what was detected, for example Frameworks: next (apps/web), vitest. Both basta and jscpd --dead-code print it.
  • New basta flags: --list-frameworks prints the list. --framework <name> treats a framework as present, which helps when the scan starts below its package.json. --no-frameworks turns detection off. --frameworks-config <file> loads your own definitions, in YAML or JSON, in the same shape as the built-in list. basta also picks up basta.frameworks.{yaml,yml,json} from the working directory. Your definitions can add a framework basta does not know, or replace a built-in one that has the same name. If the file fails to load, basta stops with an error, because running without it would report as dead the very files the definitions protect.
  • A definition can also list the names its framework looks up in your code, under globals. The built-in list has getServerSideProps, generateMetadata and the route segment config for Next; loader, action and meta for Remix and React Router; load, actions, prerender and the hooks for SvelteKit; getStaticPaths for Astro; the Gatsby Node, browser and SSR APIs; the lifecycle methods of Angular and Nest; onRequest* for Cloudflare Pages Functions; handler for Netlify and Serverless functions; and more. basta treats a declaration with such a name as used. It never reports it, including under --include-entry-exports and as an unused member, and everything the declaration calls stays reachable.
  • A plain name in globals applies to every file of the project. The { names, files } form limits names to the files the framework reads them from, so loader counts for Remix under the app directory and is an ordinary name everywhere else. This also fixes a React Router route named from routes.ts. basta reaches that file through a string, so it is not an entry point, and its loader used to be reported as an unused export.
  • Nitro now follows srcDir and treats tasks/ as loaded by the framework.
  • See fixtures/dead-code-demo. (#​1087)

• .jscpd.json can hold dead-code settings in a section of their own. The deadCode key (also spelled dead-code or basta) used to be a boolean that turned the mode on. It can now also be an object with these keys: enabled, categories, minConfidence, minLines, entry, ignore, includeTests, includeEntryExports, threshold, and the framework settings frameworks (definitions written inline, in the shape of frameworks.yaml), frameworksConfig, framework and noFrameworks.

  • The object only supplies settings. It turns the mode on only when it says "enabled": true, so you can keep clone settings and dead-code settings in one file and choose the run on the command line. "deadCode": true still works as the switch.
  • A flag wins over the section. The section wins over the older top-level keys (minConfidence, entry, deadCodeCategories, …), which still work.
  • minLines and threshold exist only inside the section, because the top-level keys with those names are about clones. The top-level minLines is the smallest clone to report and is never applied to a dead-code run. The top-level threshold is a limit for duplicated lines. A dead-code run still falls back to it when the section sets no threshold, as before.
  • A misspelled key inside the section is reported by name.
  • jscpd --dead-code and --dashboard now also pick up basta.frameworks.{yaml,yml,json} from the working directory.
  • The standalone basta binary reads the same section from the same file. It has a new -c, --config <file> flag. Without it, basta looks in the working directory for .jscpd.json, .config/jscpd.json or package.json. Both tools give the same result when you start them in the same directory.
  • See fixtures/dead-code-demo. (#​1087)

Fixes

We ran basta next to knip and fallow on 55 repositories: the GitHub trending lists for JavaScript, TypeScript, Vue, Svelte and Astro, plus the source code of Nuxt, Next.js, Svelte, Gatsby and Astro. The run found these problems in basta, all fixed in [#​1087](#​1087:

• --dead-code was very slow on projects with many path aliases. basta tested every import against every alias in the project, and it did the slow check first: comparing the importer's path with the directory of the config that declared the alias, one path segment at a time. A monorepo with 150 packages, each listing a few hundred paths, took 198 s (ever-gauzy). Next.js took 83 s. basta now checks first whether the alias pattern matches the import at all, which fails on the first character for almost every alias. The same two projects now take 3.3 s and 4.4 s, and the findings are byte for byte the same.
• A catch-all alias made every package import slow. With "*": ["./*", "../../node_modules/*"], an import of react went through the resolver from every file, and each miss built and hashed about twenty candidate paths. The module index can now tell in two lookups whether a path could name any module, under any extension or as a directory index, and the answer is exact. LibreChat went from 4.0 s to 0.86 s with identical findings.
• Vite's '@': '/src' alias was read as the root of the file system. In a Vite alias target a leading / means the project root, as it does in a URL, and many projects write the alias that way. basta lost every @/ import in such a project and reported its components as unused files at 95% confidence. MoeKoeMusic went from 55 unused files to 0.
• require(`./x`) with backticks was ignored. A template literal with nothing interpolated is as static as a quoted string, and Gatsby writes every string that way. Gatsby went from 584 unused files to 352.
• An arrow function in a Svelte or Astro attribute broke parsing. In <script on:load={() => { … }} src=…>, basta took the > of => for the end of the tag and passed the rest of the attribute to the JavaScript parser as the component's script. The file failed to parse, and everything it imports was reported as unused. cobalt went from 37 unused files to 8.
• Django migrations and management commands were reported as unused files. So were admin.py, apps.py, template tags, and the modules that settings name by dotted path. Django, Alembic and Scrapy are now in the framework list, detected by manage.py, alembic.ini and scrapy.cfg. AdventureLog went from 144 unused Python files to 6.
• A file named only by a path string without an extension is no longer reported at full confidence. resolve(distDir, 'runtime/handlers/island') is how a framework registers a file it loads itself. It is not an import, and basta does not treat it as one. But a file whose own path ends the same way now gets a new reason, path-appears-in-string ("its path appears in a string literal"), which costs 40 points. That puts the file under the default threshold of 60, and it still shows up with --min-confidence 0. Nuxt went from 83 unused files to 46. The reason is a new possible value of reasons in the JSON report.
• --dead-code read a WXT browser extension as almost entirely dead (#​1082): the framework's entrypoints/ directory — background, content scripts, popup pages — was not recognized as entry points, and its @/~ → srcDir, @@/~~ → root aliases live only in the generated .wxt/tsconfig.json, which no repository commits, so the whole tree dangled and cascaded (Tencent/BrowserSkill: 27.9% "unused", 115 unused files — now 0.4% and 5). A wxt.config.* now marks the entrypoints and auto-import directories as entries, honoring srcDir, entrypointsDir and imports: false, and declares the conventional aliases, the same way nuxt.config.* roots Nuxt's directories and svelte.config.* supplies $lib. (#​1083)
• Markup, stylesheet and template files (HTML, XML, SVG, CSS, Handlebars, …) were assigned a complexity, counting words like if, for or a media query's and as branches — an HTML page could top the "Most complex files" list. These formats now have complexity 0, like prose and data files already did, and are therefore no longer counted as code by the health score: an all-markup project reports "no code files" instead of being scored on its markup. Component formats (Vue, Svelte, Astro) still count in full through their script blocks. The markup block of a component file (tokenized as html) is now also excluded from the duplication share, matching the css/scss blocks that already were. (#​1081) (#​1084)
