What is this?

This package exposes the names of popular packages on the public npm registry. The definition of the term popular here is the same as what npm itself calls high-impact. They classify packages as having a high impact on the ecosystem when a package meets one or more of the following conditions:

• download count of 1 000 000 or more per week
• depended on by 500 or more other packages

When should I use this?

Please use this for fun experiments when researching the npm registry.

Install

This package is ESM only. In Node.js (version 16+), install with npm:

npm install npm-high-impact

In browsers with esm.sh:

API

This package exports the identifiers npmHighImpact, npmTopDependents, and npmTopDownloads. There is no default export.

npmHighImpact

List of top package names (Array<string>).

Sorted by most downloaded first. Packages that don’t reach the download threshold but are depended on a lot are listed after that in order of dependents. Includes (unique) packages from npmTopDependents and npmTopDownloads.

npmTopDependents

List of package names that are depended on a lot (Array<string>).

Sorted by most dependents first.

npmTopDownloads

List of package names that are downloaded a lot (Array<string>).

Sorted by most downloaded first.

Data

👉 Note: not all of these packages are popular. There are some false-positives, such that download counts can be gamed.

Scripts

This repo includes several scripts to crawl different services.

All packages

node script/crawl-packages.js

Used to take a day but as this uses ecosyste.ms now it is very fast, 30min to 1h. Slightly less complete as actually using npm, but as npm is unusable, I’ll take it.

Top downloads

node script/build-top-dependent.js
node script/build-top-download.js
node script/build-top.js

These generate the JS files.

Types

This package is fully typed with TypeScript. It exports no additional types.

Compatibility

This package is at least compatible with all maintained versions of Node.js. As of now, that is Node.js 16+. It also works in Deno and modern browsers.
