| # install-graph |
|
|
| Author: Dmitriy Semenkevich (dimhold) |
|
|
| This dataset measures what is physically installed in `node_modules` for 5 real projects, walked on disk rather than read from a lock file. |
|
|
| Headline, from the repository: "In a working Angular front end, 532 of the 1,729 installed packages are second and third copies of a name already present. They take 52.2 MB and 7,904 files", 14.4% of everything in `node_modules`. Nothing in this dataset was generated by a model. |
|
|
| This is a mirror. The canonical home is the Zenodo record and the GitHub repository; criteria, limitations and full tables live there. |

| ## Files |
|
|
| | path | what it is | |
| |---|---| |
| | `out/projects.json` | one row per project: installed packages, distinct names, duplicate copies and bytes, depth | |
| | `out/results.json` | the joined analysis output | |
| | `out/packages-*.json` | every installed package per project with version, nesting, bytes and files | |
| | `out/all-names.txt` | the distinct package names across projects | |
|
|
| Files ending in `.jsonl` here are `.ndjson` in the GitHub repository, renamed so the viewer reads them; the content is unchanged. |
|
|
| ## How it was produced |
|
|
| `scan.mjs` walks `node_modules` on disk and `analyze.mjs` joins the scan with registry metadata. The counting rules and the disproof condition were committed before the first number (`CRITERIA.md` in the repository). Not mirrored here: `out/maintainers.jsonl`, the per package npm registry pull with the public account names of about 600 maintainers; it is third party registry metadata and stays in the GitHub repository. The scripts that turn these files into every number are in the GitHub repository. One of the 5 scanned projects is a private repository; its name is written as `cli-tool` everywhere, including `out/packages-cli-tool.json`. Its counts are unchanged. |
