Openchangelog

Openchangelog is an open source, self hostable Changelog Rendering Website. Changelogs are written in Markdown and can be integrated from different sources, e.g local or GitHub.

Configuration

You can configure your Changelog by adapting the config.yaml file.

Look & Feel

title: The title is displayed above all Changelog articles.

# config.yaml
page:
  title:

subtitle: The subtitle is displayed below the title.

# config.yaml
page:
  subtitle:

Logo: Your logo is displayed in the header.

# config.yaml
page:
  logo:
    src: # url to image
    width: # width of logo as string e.g. 70px
    height: # height of logo as string e.g 30px
    link: # optional link that the logo points to

Local Data Source

You can specify a local file path to a directory containing your Changelog Markdown files.

# config.yaml
local:
  filesPath: .testdata

Github Data Source

You can specify your repository and path to a directory inside the repo containing your Changelog Markdown files. You can authenticate via a Github App or Personal Access Token.

# config.yaml
github:
  owner: # gh username
  repo:
  path: # path inside repo
  auth:
    accessToken: # access token with a access to the specified repo
    # or
    appPrivateKey:
    appInstallationId:

Cache

You can configure a cache to improve latency and avoid hitting rate limits from e.g. Github.
Internally httpcache is used to cache the request to Github. You can choose between a memory, disk and s3.

# config.yaml
cache: 
  type: # disk, memory, s3
  disk: # used when type is disk
    location: # the file system location of the disk cache
    maxSize: # in bytes
  s3: # used when type is s3
    bucket: # the bucket url, env AWS_ACCESS_KEY_ID and AWS_SECRET_KEY are used as credentials

Writing Changelogs

Each new Changelog, e.g. from a new release, is written in a new Markdown file, this allows adding custom metadata for each article using the markdown Frontmatter.
All files are stored in the same directory, either local or in remote sources.

Filename Format

The ordering of the changelog files is important.
The displayed Articles in the UI are ordered by their filename in descending order. We recommend prefixing the file with the release version.

{version}.{title}.md
v0.0.1.darkmode.md
v0.0.2.i81n.md

Content Format

Changelogs are written in Markdown, we are compliant with CommonMark 0.31.2 (thanks to goldmark).
You can use the Frontmatter to specify additional info:

• title: Displayed as a bold title at the top of the Changelog Article.
• description: Displayed below the title.
• publishedAt: An ISO 8601 datetime that is diplayed next to the Changelog Article.
