@changesets/changelog-github

@changesets/changelog-github

A changelog generator for Changesets that links to GitHub commits, PRs, and authors.

Usage

The @changesets/changelog-github package requires a GITHUB_TOKEN with read:user and repo:status permissions. Add it to your repository's GitHub Action secrets and your .env file:

GITHUB_TOKEN=token_here

Then you can use it in the changelog option:

{
  "changelog": ["@changesets/changelog-github", { "repo": "owner/repo" }]
}

Options

repo

• Type: string
• Default: process.env.GITHUB_REPOSITORY

Specify the <org>/<repo> slug of your GitHub repository. If you intend to run this locally, specify the option explicitly or set the GITHUB_REPOSITORY environment variable.

When running in GitHub Actions, GITHUB_REPOSITORY is automatically set, so you can omit this option if you are only running in GitHub Actions.

disableThanks

• Type: boolean
• Default: false

Set true to drop the "Thanks [@user]!" attribution from each line.

It is recommended to not set "disableThanks": true when using the template option as the {authors} token would return an empty string, which could lead to unexpected results.

template

• Type: string
• Experimental

Experimental. The template option and its token syntax may change in any release, including a patch. If you rely on it, pin the exact @changesets/changelog-github version.

This option allows you to customize the format that should be used for the generation of a single changelog line. For example, the default template generates this Markdown:

- [#123](https://github.com/<org>/<repo>/pull/123) [`a1b2c3d`](https://github.com/<org>/<repo>/commit/a1b2c3d4e5f6a7b8c9d0e1f2a3b4c5d6e7f8a9b0) Thanks [@ghost](https://github.com/ghost)! - fix the thing

Each piece of information can be dynamically represented with tokens. The above example can be represented as:

\n\n- {pull} {commit} Thanks {authors}! - {summary}

Tokens

The template option supports these tokens.

Token	Description	Example
{summary}	The first line of the changeset Markdown content.	fix the thing
{ref}	Link to either the PR or commit (if the changes were pushed directly). Wrapped in parenthesis.	([#123](url))
{pull}	Link to the PR if available.	[#123](url)
{commit}	Link to the commit.	[`abc1234`](url)
{authors}	Link to the GitHub user profile of the main author of the commit (and PR).	[@ghost](url)

If a token is used and its data is absent, the token will generate an empty string. The continuation lines of a multi-line summary are also always appended below the template, indented by two spaces.

Examples:

template	Generated Markdown
"\n\n- {pull} {commit} Thanks {authors}! - {summary}"	\n\n- [#123](url) [`abc1234`](url) Thanks [@ghost](url)! - fix the thing
"\n\n- {summary} {ref}"	\n\n- fix the thing ([#123](url)) or - fix the thing ([`abc1234`](url))
"\n\n- {summary} (thanks {authors}!)"	\n\n- fix the thing (thanks [@ghost](url)!)
"\n\n- {summary} {pull}"	\n\n- fix the thing [#123](url)
