Summary

  • Update package.json with NPM metadata (@flagsmith/backstage-plugin)
  • Add release workflow with multiple triggers:
    • PR previews: Publishes @next tag with version like 0.1.0-pr.5.abc1234
    • GitHub Release: Publishes when creating a release via GitHub UI
    • Manual dispatch: Allows triggering patch/minor/major releases
  • Add NPM version badge to README
  • Extract PR comment script to scripts/comment-pr-preview.js for maintainability

Manual Setup Required (After Merge)

  1. Ensure @flagsmith NPM organization exists
  2. Create NPM automation token with publish permissions
  3. Add NPM_TOKEN secret to GitHub repository settings

Test plan

  • Verify workflow syntax is valid
  • After merge, configure NPM_TOKEN secret
  • Test manual release trigger with patch version

Closes #6423

- Update tsconfig.json with proper exclusions and type definitions
- Change build:all script to check if declaration files were generated
- This approach safely handles node_modules TypeScript errors while
  still failing if our source code has actual type errors

Replace complex shell script with simpler fallback:
- Run tsc (may show errors from node_modules)
- Fall back to checking if declaration files were generated
- This handles the react-markdown type errors gracefully

This method was a leftover from the old backend plugin architecture.

Implements #6421 - adds `/alpha` export path that uses Backstage's new
declarative frontend system while maintaining backward compatibility with
the existing legacy export.

Changes:
- Add `@backstage/frontend-plugin-api` dependency
- Create `src/alpha.ts` with new frontend system plugin using:
  - EntityContentBlueprint for FlagsTab
  - EntityCardBlueprint for FlagsmithOverviewCard and FlagsmithUsageCard
- Add exports and typesVersions configuration to package.json

Usage:
- Legacy: `import { flagsmithPlugin } from '@internal/plugin-flagsmith'`
- Alpha: `import flagsmithPlugin from '@internal/plugin-flagsmith/alpha'`

Consolidate alpha.ts into index.ts as the main plugin export.
The plugin now uses createFrontendPlugin with EntityContentBlueprint
and EntityCardBlueprint from the new Backstage frontend system.

Exports:
- default: flagsmithPlugin (new frontend system)
- flagsmithPlugin: named export for compatibility
- FlagsTab, FlagsmithOverviewCard, FlagsmithUsageCard: components

Remove the summary stats (X Enabled, Y Disabled) from the header as they
were based on default_enabled which doesn't reflect actual per-environment
status. A flag could be enabled in Production but disabled in Development,
making this count confusing. Following LaunchDarkly plugin pattern of
showing only project name and total flag count.
