We encourage other developers to join the project and contribute to making this library constantly better and more stable. If you are missing a feature, please create a feature request so we can discuss it and coordinate further development. To report a bug, please check existing issues first, and if found, leave a comment on the issue. Otherwise, file a bug or create a pull request with a proposed fix.
Submitting a Pull Request
This section explains how to submit a pull request.
- Login to your GitHub account and fork the
solacecommunity/angular-solace-message-client
repo. - Make your changes in a new Git branch. Name your branch in the form
issue/xxx
withxxx
as the related GitHub issue number. Before submitting the pull request, please make sure that you comply with our coding and commit guidelines. - Run the command
npm run before-push
to make sure that the project builds, passes all tests, and has no lint violations. Alternatively, you can also run the commands one by one, as following:npm run lint
Lints all project files.npm run build
Builds the project and related artifacts.npm run test:headless
Runs all unit tests.
- Commit your changes using a descriptive commit message that follows our commit guidelines.
- Before submitting the pull request, ensure to have rebased your branch based on the master branch as we stick to the rebase policy to keep the repository history linear.
- Push your branch to your fork on GitHub. In GitHub, send a pull request to
angular-solace-message-client:master
. - If we suggest changes, please amend your commit and force push it to your GitHub repository.
When we receive a pull request, we will carefully review it and suggest changes if necessary. This may require triage and several iterations. Therefore, we kindly ask you to discuss proposed changes with us in advance via the GitHub issue.
Development
Make sure to use Node.js version 22.11.0 for contributing to this library. We suggest using Node Version Manager if you need different Node.js versions for other projects.
For development, you can uncomment the section PATH-OVERRIDE-FOR-DEVELOPMENT
in tsconfig.json
. This allows running tests or serving applications without having to build dependent modules first.
The following is a summary of commands useful for development of angular-solace-message-client
. See file package.json
for a complete list of available NPM scripts.
-
npm run solace-message-client:lint
Lints the library. -
npm run solace-message-client:build
Builds the library. -
npm run solace-message-client:test
Runs unit tests.
-
npm run solace-message-client-testing-app:serve
ornpm run start
Serves the testing app (try me app) on http://localhost:4200.
Uncomment the sectionPATH-OVERRIDE-FOR-DEVELOPMENT
intsconfig.json
to have hot module reloading support. -
npm run solace-message-client-testing-app:build
Builds the testing app intodist
folder using the productive config. -
npm run solace-message-client-testing-app:lint
Lints the testing app.
-
npm run solace-message-client:typedoc
Generates the API documentation (TypeDoc) for the library. The output is written todist/solace-message-client-api
. -
npm run changelog
Generates the changelog based on the commit history. The output is written toCHANGELOG.md
, which will be included indocs/site/changelog/changelog.md
using the templatedocs/site/changelog/changelog.template.md
.
Code Formatting
To ensure consistency within our code base, please use the following formatting settings.
-
For IntelliJ IDEA
Import the code style settings of.editorconfig.intellij.xml
located in the project root. -
For other IDEs
Import the code style settings of.editorconfig
located in the project root.
Coding Guidelines
In additional to the linting rules, we have the following conventions:
- We believe in the Best practices for a clean and performant Angular application and the Angular Style Guide.
- We expect line endings to be Unix style (LF) only. We suggest that you set
core.autocrlf
tofalse
so that Git does not perform any automatic conversions on both, checkout and commit, respectively. If you cloned the repository withcore.autocrlf=true
, you either need to manually convert the line endings back toLF
or, which is the easier way, setcore.autocrlf
tofalse
and clone the repo anew.
git config --global core.autocrlf false
- Observable names are suffixed with the dollar sign (
$
) to indicate that it is anObservable
which we must subscribe to and unsubscribe from. - We use explicit
public
andprivate
visibility modifiers (except for constructors) to make the code more explicit. - We write each RxJS operator on a separate line, except when piping a single RxJS operator. Then, we write it on the same line as the pipe method.
- We avoid nested RxJS subscriptions.
- We document all public API methods, constants, functions, classes or interfaces.
- We structure the CSS selectors in CSS files similar to the structure of the companion HTML file and favor the direct descendant selector (
>
) over the non-restrictive descendant selector ( - When referencing CSS classes from within E2E tests, we always prefix them with
e2e-
. We never reference e2e prefixed CSS classes in stylesheets.
Commit Guidelines
We believe in a compact and well written Git commit history. Every commit should be a logically separated changeset. We use the commit messages to generate the changelog.
Each commit message consists of a header, a summary and a footer. The header has a special format that includes a type, an optional scope, and a subject, as following:
<type>(<scope>): <subject>
[optional summary]
[optional footer]
Type
feat
: new featurefix
: bug fixdocs
: changes to the documentationrefactor
: changes that neither fixes a bug nor adds a featureperf
: changes that improve performancetest
: adding missing tests, refactoring tests; no production code changechore
: other changes like formatting, updating the license, updating dependencies, removal of deprecations, etcci
: changes to our CI configuration files and scriptsrevert
: revert of a previous commitrelease
: publish a new release
Scope
The scope should be the name of the NPM package or application affected by the change.
solace-message-client
: If the change affects the@solace-community/angular-solace-message-client
NPM package.tryme
: If the change affects the test application.
Subject
The subject contains a succinct description of the change and follows the following rules:
- written in the imperative, present tense ("change" not "changed" nor "changes")
- starts with a lowercase letter
- has no punctuation at the end
Summary
The summary describes the change. You can include the motivation for the change and contrast this with previous behavior.
Footer
In the footer, reference the GitHub issue and optionally close it with the Closes
keyword, as following:
closes #xxx
And finally, add notes about breaking changes, if there are any. Breaking changes start with the keyword BREAKING CHANGE:
. The rest of the commit message is then used to describe the breaking change and should contain information about the migration.
BREAKING CHANGE: Removed deprecated API for ...
To migrate:
- do ...
- do ...
Deprecation Policy
You can deprecate API in any version. However, it will still be present in the next major release. Removal of deprecated API will occur only in a major release.
When deprecating API, mark it with the @deprecated
JSDoc comment tag and include the current library version. Optionally, you can also specify which API to use instead, as following:
/**
* @deprecated since version 2.0. Use {@link otherMethod} instead.
*/
function someMethod(): void {
}
Deployments
We have the following artifacts that are deployed from our GitHub Actions workflow when a release commit is merged into the master branch.
NPM Packages
We publish our packages to the NPM registry under the solace-community organization. Packages are published on behalf of the Solace collaborator user.
We have the following packages:
Versioning
We follow the same SemVer (Semantic Versioning) philosophy as Angular, with major versions being released at the same time as major versions of the Angular framework.
Major Version:
Major versions contain breaking changes.
Minor Version
Minor versions add new features or deprecate existing features without breaking changes.
Patch Level
Patch versions fix bugs or optimize existing features without breaking changes.
Release Checklist
This chapter describes the tasks to publish a new release to NPM.
- Update
/projects/solace-message-client/package.json
with the new version. - Run
npm run changelog
to generate the changelog. Then, review the generated changelog carefully and correct typos and formatting errors, if any. - Commit the changed files using the following commit message:
release(solace-message-client): vX.X.X
. ReplaceX.X.X
with the current version. Later, when merging the branch into the master branch, a commit message of this format triggers the release action in our GitHub Actions workflow. - Push the commit to the branch
release/X.X.X
and submit a pull request to the master branch. ReplaceX.X.X
with the current version. - When merged into the master branch, the release action in our GitHub Actions workflow does the following:
- Creates a Git release tag
- Publishes
@solace-community/angular-solace-message-client
package to NPM (https://www.npmjs.com/package/@solace-community/angular-solace-message-client) - Creates a release on GitHub (https://github.com/solacecommunity/angular-solace-message-client/releases)
- Deploys Testing Application (Try Me) to https://solacecommunity.github.io/angular-solace-message-client/tryme
- Publishes API Documentation (TypeDoc) to https://solacecommunity.github.io/angular-solace-message-client/api
