@bloomreach/broccoli

Broccoli

This is a component library of all basic and common components across all bloomreach project apps. This will be primarily primitive components and possibly some specialized items as well.

Viewing Available Components

Visit the library storybook to view the latest available components.

Using library in a project

Install the following libraries to the project dependencies

npm i --save --save-exact @bloomreach/broccoli @bloomreach/banana-theme

Note:

The library @bloomreach/banana-theme is required only to bring fonts used by default in the global design system which is going to be used across all Bloomreach applications. Using it as a separate dependency in the end application is a temporary solution and will be changed in the near future by hiding inside @bloomreach/broccoli library.

Components

In case project settings are properly established, use the components in the application like so

import { <ComponentName> } from "@bloomreach/broccoli";

Styles & Fonts

Do the following steps to make styles and fonts available

• Import broccoli styles along with fonts by adding the following lines in the main application style file

  // main.scss
  
  @import '@bloomreach/banana-theme/css/fonts.css';
  @import '@bloomreach/broccoli/style.css';
  
  ...
  

• Additionally, set the font-family property to the root element using CSS custom properties available from the broccoli library

  // main.scss
  
  ...
  
  html, body {
    font-family: var(--broccoli-font-family-primary);
  }
  
  ...
  

The full list of available CSS custom properties will be available soon. Now just use the browser dev tools to see all available CSS custom properties. Filter them with the --broccoli- prefix to reduce the amount.

ATTENTION:

Please, avoid using --banana-... CSS custom properties as they are intended to be used inside the broccoli library itself.

Development

Prerequisites

• Node.js 18.x
• NPM 9.x

Install all dependencies

npm ci

Run the storybook

npm run start

After that, any changes in the source code will automatically be reflected in the storybook.

Branching types

To manage and automate complex release workflow based on multiple Git branches and distribution channels used the semantic-release library. Check the documentation for more details. The current setup is reduced and simplified as much as possible, however, it is flexible and might be extended in the future if needed.

The current branch types are explained below.

• The master branch - is a permanent branch, where releases happen for the latest versions. All versions from that branch will be published to the npm registry with a latest dist-tag;
• The next branch should be used when we want to develop an important feature, which is a breaking change. Considering the scope of this feature we want to make it available, at first, only to a limited amount of users in order to get feedback or run tests. Once we get that feedback we can make improvements and ultimately make the new feature available to all users by merging changes into the master branch; Releases from the next branch will be published to the npm registry with a next dist-tag;
• The maintenance branches (i.e. 2.x to maintain release v2). The maintenance branch is a type of branch that allows publishing releases with a semantic version on top of the codebase of an old release. This is useful when you need to provide fixes or features to users who cannot upgrade to the last version of the package;
• Feature branches (like feature/BR-XX-my-awesome-feature, fix/BR-XX-that-is-life) or any other kind of branch to commit small units of work that do not produce releases (until merged into one of the branches above). These branches are ignored from now on as they don’t have to trigger releases;

The following changes should be done to change or extend the current setup:

• Add a new release/maintenance/pre-release branch to the semantic-release configuration in ./.releaserc, check the documentation for more details;
• Update the Gitlab pipeline release job to allow running it with the new branch, check ./.gitlab-ci.yml;
• Verify that the new branch is marked as protected in the repository settings.

Find more examples of possible release workflows in the official semantic-release documentation.

Commit Message Format

To have an automated release process the git commit messages must follow the following format. This specification following Conventional Commits. It provides an easy set of rules for creating an explicit commit history. This convention dovetails with semantic version, by describing the features, fixes, and breaking changes made in commit messages.

Each commit message consists of a header, a body, and a footer.

<header>
<BLANK LINE>
<body>
<BLANK LINE>
<footer>

The header is mandatory and must conform to the Commit Message Header format.

The body is optional. When the body is present it must be at least 20 characters long and must conform to the Commit Message Body format.

The footer is optional. The Commit Message Footer format describes what the footer is used for and the structure it must have.

The commit contains the following structural elements:

• fix: a commit of the type fix patches a bug in your codebase (this correlates with PATCH in Semantic Versioning).
• feat: a commit of the type feat introduces a new feature to the codebase (this correlates with MINOR in Semantic Versioning).
• BREAKING CHANGE: a commit that has a footer BREAKING CHANGE:, or appends a ! after the type/scope, introduces a breaking API change (correlating with MAJOR in Semantic Versioning). A BREAKING CHANGE can be part of commits of any type.
• types other than fix: and feat: are allowed, see types.
• footers other than BREAKING CHANGE: may be provided and follow a convention similar to git trailer format.

Additional types are not mandated by the Conventional Commits specification, and have no implicit effect in Semantic Versioning (unless they include a BREAKING CHANGE).

Commit Message Header

<type>(<scope>): <short summary>
  │       │             │
  │       │             └─⫸ Summary in present tense. Not capitalized. No period at the end.
  │       │
  │       └─⫸ Commit Scope: Right now not used but will be expanded in the near future.
  │
  └─⫸ Commit Type: build|chore|ci|docs|feat|feature|fix|perf|refactor|style|test.

The <type> and <summary> fields are mandatory, the (<scope>) field is optional and not used now.

Type

Must be one of the following:

• build - changes that affect the build system or external dependencies; Hidden from the release notes;
• chore - changes which are not fit to the rest of the types. Hidden from the release notes;
• ci - changes to our CI configuration files and scripts. Hidden from the release notes;
• docs - documentation only changes. Hidden from the release notes;
• feat - a new feature. Appeared in the release notes under section Features;
• feature - the alias for the typefeat;
• fix - a bug fix. Appeared in the release notes under section Bug Fixes;
• perf - a code change that improves performance. Appeared in the release notes under section Performance Improvements;
• refactor - a code change that neither fixes a bug nor adds a feature. Hidden from the release notes;
• revert - revert of the previous changes. Appeared in the release notes under section Reverts;
• style - changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc). Hidden from the release notes;
• test - adding missing tests or correcting existing tests. Hidden from the release notes.

If the prefix is feat, fix, perf or revert, it will appear in the release notes. However if there is any BREAKING CHANGE, the commit will always appear in the changelog.

Other prefixes are up to your discretion. Suggested prefixes are build, ci, docs ,style, refactor, style, test and chore for non-changelog related tasks.

Scope

Not used currently.

Summary

Use the summary field to provide a succinct description of the change:

• use the imperative, present tense: "change" not "changed" nor "changes"
• don't capitalize the first letter
• no dot (.) at the end

Commit Message Body

Just as in the summary, use the imperative, present tense: "fix" not "fixed" nor "fixes".

Explain the motivation for the change in the commit message body. This commit message should explain why you are making the change. You can include a comparison of the previous behavior with the new behavior in order to illustrate the impact of the change.

Commit Message Footer

The footer can contain information about breaking changes and is also the place to reference Jira tickets, and other MRs that this commit closes or is related to.

For example:

BREAKING CHANGE: <breaking change summary>
<BLANK LINE>
<breaking change description + migration instructions>
<BLANK LINE>
<BLANK LINE>
<Closes|Fixes> BR-<issue number>

Breaking Change section should start with the phrase BREAKING CHANGE: followed by a summary of the breaking change, a blank line, and a detailed description of the breaking change that also includes migration instructions.

Similarly, a Deprecation section should start with DEPRECATED: followed by a short description of what is deprecated, a blank line, and a detailed description of the deprecation that also mentions the recommended update path.

Revert commits

If the commit reverts a previous commit, it should begin with revert: , followed by the header of the reverted commit.

The content of the commit message body should contain:

• information about the SHA of the commit being reverted in the following format: This reverts commit <SHA>,
• a clear description of the reason for reverting the commit message.

Testing

When adding changes for any component part of the library it is mandatory to have them covered by tests. These tests need to be meaningful and developed with extensive coverage in mind. By their nature components will be used in a wide variety of scenarios and so extensive coverage is crucial in order to avoid unpredictable results.

Unit tests

The Vitest unit test framework is used for the unit testing. The unit test files should end with *.spec.ts and place close to the component or module which is going to be tested.

Releasing

The release of the new version is going to be done automatically when the changes reach one of the release branches and commit messages contain one of the structural elements

The Gitlab pipeline runs all the checks and if the library is in good order:

• The release notes will be updated according commit messages history;
• The library version will be bumped;
• The new commit will be created with a version and changed release notes;
• The new git tag will be created in the repository;
• The new version of the library will be published to npm;

Only a few manual steps should be done after all:

• Announce in the slack channel #broccoli-component-library about new release :tada:;
• Mark the new version as released in the releases section in Jira once the ticket is merged and closed;
• Take a break and then pick up the next challenge :muscle:!
