    CircleCI Coverage Status semantic-release Commitizen friendly npm version

    fetch the changelog for an npm package from GitHub

    How it works

    Right now only packages hosted on GitHub are supported. npm-fetch-changelog will get the package info and repository URL from npm, then try to fetch the GitHub release for each relevant version tag. If no GitHub release is found it will fall back to trying to parse the package's or GitHub releases are way more reliable for this purpose though, so please use them!


    npm-fetch-changelog inevitably fails to find changelog entries for some packages/releases because many maintainers are not very detail-oriented about it (and don't choose to use excellent tools that would do the work for them, like semantic-release).

    However, I've also seen cases where some versions were never published to npm (for instance, at the time of writing, superagent version 5.0.0 was never published to npm, yet it does have a changelog entry). npm-fetch-changelog currently only displays changelog entries for published versions.

    API Tokens

    GitHub heavily rate limits public API requests, but allows more throughput for authenticated requests. If you set the GH_TOKEN environment variable to a personal access token, npm-fetch-changelog will use it when requesting GitHub releases.

    npm-fetch-changelog will also use the NPM_TOKEN environment variable or try to get the npm token from your ~/.npmrc, so that it can get information for private packages you request.

    You can also store one or both of these tokesn in ~/.config/npm-fetch-changelog.json:

      "githubToken": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
      "npmToken": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"


    npm i -g npm-fetch-changelog
    npm-fetch-changelog <package name>[@<range>]
    what-broke <package name>[@<range>]

    Prints changelog entries fetched from GitHub for each version released on npm in the given range.

    what-broke is just a shortcut for npm-fetch-changelog --no-minor.


    -r, --range

    semver version range to get changelog entries for, e.g. ^7.0.0 (defaults to > the version installed in the working directory, if it exists)

    You can also pass the range together with the package name (you might need to quote it):

    npm-fetch-changelog 'foo@>=2'


    output JSON instead of Markdown


    include prerelease versions


    exclude minor versions


    exclude patch versions (defaults to --no-minor)

    Node.js API

    (the CLI just uses this under the hood)

    import { fetchChangelog } from 'npm-fetch-changelog'
    async function fetchChangelog(
      package: string,
      options?: {
        include?: ?(((version: string) => boolean) | {
          range?: ?string,
          prerelease?: ?boolean,
          minor?: ?boolean,
          patch?: ?boolean,
    ): Promise<{[version: string]: {
      version: string,
      header: string,
      body?: string,
      date?: Date,
      error?: Error,


    npm i npm-fetch-changelog
