Fixes #1638

What changes did you make and why did you make them?

• Added scripts to /backend/package.json for running the cloneOrSyncCollectionsgs.js and clearDevCollections.js scripts with various flags.
• The scripts accept the --mock flag and flags for each supported collection:
  • For cloneOrSyncCollectionsgs.js: --projects, --recurring-events
  • For clearDevCollections.js: --projects, --recurring-events, --events, --checkins
• This makes it easier and more consistent to run these scripts from the command line or via yarn, and helps with developer productivity and onboarding.

Usage Guide

1. Change to the backend directory:

cd backend

2. Use --mock to preview what will happen (no data will be changed):

# clearDevCollections
yarn clearDevCollections --projects --mock
yarn clearDevCollections --recurring-events --mock
yarn clearDevCollections --all --mock

# cloneOrSyncCollectionsgs
yarn cloneOrSyncCollectionsgs --projects --mock
yarn cloneOrSyncCollectionsgs --recurring-events --mock

3. Confirm the output is satisfactory.

4. Remove --mock to run the operation on the live DEV database:

# clearDevCollections
yarn clearDevCollections --projects
yarn clearDevCollections --recurring-events
yarn clearDevCollections --all

# cloneOrSyncCollectionsgs
yarn cloneOrSyncCollectionsgs --projects
yarn cloneOrSyncCollectionsgs --recurring-events

Tip: Always use --mock first to verify what will be deleted or cloned before running the actual operation.

• --initial Initial clone (insertMany, skip duplicates)
• --mock Only print what would be written, do not write

Example Commands

Preview what would be deleted from all collections (no data is changed):

# clearDevCollections
cd backend
yarn clearDevCollections --all --mock

Actually clear the 'projects' collection:

# clearDevCollections
cd backend
yarn clearDevCollections --projects

Clone projects and recurring events from PROD to DEV (mock mode):

# cloneOrSyncCollectionsgs
cd backend
yarn cloneOrSyncCollectionsgs --projects --mock
yarn cloneOrSyncCollectionsgs --recurring-events --mock

Clone only recurring events (real operation):

# cloneOrSyncCollectionsgs
cd backend
yarn cloneOrSyncCollectionsgs --recurring-events
