This project was generated with Angular CLI.
To ensure your work follows the expected structure, ensure you are using the correct Angular CLI commands as you create new libraries, modules, and components.
Most of the modules in this library are intended to be published and consumed by third parties, specifically in support of the GSA IAE Modernization project.
The grouping folders under the libs folder divide libraries by scope. Packages that are intended to be published live under the packages folder. As other scopes are needed for internal development to house feature, utilities, or data-access modules for documentation or other purposes, new scope directories may be added.
New publishable libraries should only be created with consent from the team. These libraries should be created within the libs/packages
directory. Each publishable package should provide the following tags:
Any updates to the documentation site should first be created as a library in the libs/sam-design-system-site
directory. Depending on the type of library, create it in the appropriate subdirectory using the Angular CLI schematics to ensure consistency with the project's structure.
All libraries should share the scope:sam-design-system-site
and platform:web
tags. Add whichever type
tag of ui, data-access, utility, or feature
that is appropriate.
Finally, import the module into the sam-design-system-site
and configure the application appropriately.
Publishing happens in a few steps. From a high level,
npm version <major | minor | patch>
This step updates the main package.json version in the root directory. It also runs through each library in the angular.json projects
property and updates their package.json with the
version from the root package.json.
Finally, this script git commits the changes and creates a tag with the version number.
git push origin master
&& git push --tags
For now, this step must be run manually after the versions have been updated locally. This syncs the local changes with the remote repository.
On Github, draft a new release and write release notes. Github-release-notes (gren) can be used to assist in this.
npm run publish:libs
Note: Run npm run publish:libs -- --dry-run
to get a dry-run and not publish
Since the tarballs for the published libraries will be generated from the source code on the local machine, it is imperative that the branch on your local machine is in sync with the approved release code before publishing the library.
Once the local branch is in sync with the release branch, run the publish script. This finds each publishable library in the angular.json and publishes its code.
You can now run npm run release:patch
, npm run release:minor
, or npm run release:major
, but be careful. It will run the versioning script, add a commit and tag, push to github, run gren
to generate a release on github with notes based on PRs, then run gren
again to generate a changelog, commit it, and push it up to github.
All that executes on whatever branch you are on, and when you run it, you want to be on master. If something happens, you'll have to manually rollback 3 commits, delete the git tag, and delete the release.
Once all that is done, you still have to manually run the npm run publish:libs
script to build, pack, and publish them to npmjs. If y'all are confident, you can also add && npm run publish:libs
onto the end of the npm run release
script (for each type), and that will do everything in one step.
Note:
I'd recommend keeping them separate for awhile and getting the team comfortable with what's happening before you try that though.
In order to run the above, you need to have gren
installed and configured globally on your local machine. This requires add the npm package and also updating your path with an environment variable for gren to use.
The link to gren is here.
There is some additional configuration required to make it work smoothly.
First, you will also need to create a personal access token with repo
scope for your github account.
Under the Github profile, go to Settings -> Developer Settings -> Personal Access Tokens -> Generate New Token and then provide that to the environment variable to use gren.
Second, you need to add the repo information to package.json. This is already done on this project, but that keeps you from having to update gren
with the repo info on each push.
Run ng serve --project=myapp
for a dev server. Navigate to http://localhost:4200/
. The app will automatically reload if you change any of the source files.
Run ng generate component component-name --project=myapp
to generate a new component. You can also use ng generate directive|pipe|service|class|guard|interface|enum|module
.
Run ng build --project=myapp
to build the project. The build artifacts will be stored in the dist/
directory. Use the --prod
flag for a production build.
Run ng test
to execute the unit tests via Karma.
Run ng e2e
to execute the end-to-end tests via Protractor.
Before running the tests make sure you are serving the app via ng serve
.
Run ng build project-name
to initially output a build of the project. This will be stored in dist/
directory.
Navigate to the built project - cd dist/libs/project-name
Run npm link
(Mac users might need to run with sudo command)
Navigate back to root directory - cd ../../../
Run ng build --watch
- This will watch for any changes to the project and update the build in dist directory
On application side, from the same directory where the application's package.json is placed, run npm link @gsa-sam/project-name
.
Start up your application - Now any changes made to the project should initiate a reload and be reflected on the application.
