storybook-addon-versions

Install

npm i @tobiashochguertel/addon-versions

This addon allows you to navigate different versions of your components, if you have a setup that produces a different static Storybook build for each of your versions. As such, if you build a static Storybook and host it in, say, the following directory structure:

- static-storybook
|-- 0.0.1
|-- 0.0.2
|-- 0.1.2
|-- 0.2.5

the addon will allow you to navigate the various versions via the Versions panel:

Versions demo

Configuration

The addon attempts to get a list of available style guide versions from the root of your host. If they are found it will show a dropdown which then lets you navigate to the various versions, as such allowing users to see how a component may have changed over different versions.

Usage

Include the addon in your addons.js

import '@tobiashochguertel/addon-versions/register';

Create the Versions config at .storybook/storybook-config.json

{
  "storybook": {
    "versions": {
      "availableVersions": [
        "0.0.1",
        "0.0.2",
        "0.1.2",
        "0.2.5"
      ],
      "hostname": "localhost:8000",
      "localhost": "localhost:9001",
      "regex": "\/([^\/]+?)\/?$"
    }
  }
}

or without hostname property, to use the current hostname from the browser to generate the version links in the panel:

{
  "storybook": {
    "versions": {
      "availableVersions": [
        "0.0.1",
        "0.0.2",
        "0.1.2",
        "0.2.5"
      ],
      "regex": "\/([^\/]+?)\/?$"
    }
  }
}

Options

availableVersions: An array of available versions.
hostname: The hostname of where the static builds are. For now you need to add the path if you are expecting links to work in a local dev build but not in your normal hosted config.
localhost: Where the local dev build is, when running in dev mode
regex: This is for a regular expression that will extract the version number for your URL. This is dependant on the way you store the static storybook builds. The example above will work for the format http://localhost:port/<version>/ so for example, version 0.1.2 would be expected to be found like this http://mystorybook/0.1.2/.

Integration with CI/CD (gitlab)

  after_script:

    - test -d ./public && rm -rf ./public

The above code does the following steps:

creates an empty branch with the name gl-pages
deletes a checkout gl-pages branch: git show-ref -q --heads $PAGES_BRANCH && git branch -D $PAGES_BRANCH
checkout again the gl-pages branch from remote: git fetch origin $PAGES_BRANCH && git checkout -b $PAGES_BRANCH origin/$PAGES_BRANCH || echo "Pages branch not deployed yet."
creates a list of available Versions in the checkout gl-pages branch: test -d ./public && cd ./public && PAGES_VERSIONS=$(find . -type d -maxdepth 1 | sed '1d' | sed 's/\.\///') && cd ..
in the current branch, it checksout the head ref (detached head): git checkout $CI_COMMIT_SHA
removes the build directory, because we just need to build the new version: test -d ./public && rm -rf ./public
read out the current version of the project: CURRENT_VERSION=$(/usr/local/bin/dasel -f ./package.json --plain .version)
set the build dir-variable: BUILD_DIR="./public"
build the storybook: yarn build-storybook --quiet -o "$BUILD_DIR/$CURRENT_VERSION"
copy the addon configuration file storybook-config.json to the build-dir: cp .storybook/versioning/storybook-config.json "$BUILD_DIR/"
copy a index.html, which redirects to http://localhost/ to http://localhost/latest to the build-dir: cp .storybook/versioning/index.html "$BUILD_DIR/"
checkout gl-pages, we will endup with only the untracked files under ./public to be available: git checkout $PAGES_BRANCH
remove the latest symlink which came with the checkout from branch gl-pages: rm -f "$BUILD_DIR/latest"
create a symlink to the current version: cd $BUILD_DIR && ln -s "$CURRENT_VERSION" ./latest && cd ..
deletes the availableVersions array of the json file: /usr/local/bin/dasel delete -p json -f ./public/storybook-config.json ".storybook.versions.availableVersions"
the previous stored list of existing version get writen to the config: for PAGES_VERSION in $PAGES_VERSIONS; do /usr/local/bin/dasel put string -p json -f $BUILD_DIR/storybook-config.json -m ".storybook.versions.availableVersions.[]" "$PAGES_VERSION"; done
t.b.d. Add the current version also to the list
add the changes to the branch gl-pages: git add -A "$BUILD_DIR"
check if there are changes (because, otherwiese the pipeline fail with this step): git diff-index --quiet HEAD && echo "Nothing to commit..." || git commit --untracked-files=no -m "Add version $CURRENT_VERSION"
push the changes to the gl-pages repository via temporary-repository url wich includes also the credentials: git push $HTTPS_REMOTE gl-pages

HTTPS_REMOTE: https://gitlab-ci-token:${FUNCTIONAL_USER_TOKEN}@${CI_SERVER_HOST}/${CI_PROJECT_PATH}.git

Notes

This is a fork of https://github.com/panosvoudouris/storybook-addon-versions It appears that repo is now defunct and no longer maintained so I've forked it to continue maintenance (eg upgrade for latest storybook etc) and upgrades.
