Mandatory Tasks (DO NOT REMOVE)

• I have self-reviewed the code (A decent size PR without self-review might be rejected).
• I have updated the developer docs if this PR makes changes that would require a documentation change. N/A
• I confirm automated tests are in place that prove my fix is effective or that my feature works.

How should this be tested?

Note for reviewers: The steps below require a locally reachable Postgres instance. The project's docker-compose.yml runs the database inside Docker , to connect from the host you will need to temporarily expose port 5432. This is a local only change and is not part of this PR.

In your local docker-compose.yml, add the following under the database service, run docker compose up -d database, then follow the steps below. Remove the port mapping when done.

database:
  ports:
    - "5432:5432"

1. In .env

   DATABASE_URL=postgresql://unicorn_user:magical_password@localhost:5432/calendso
   DATABASE_DIRECT_URL=postgresql://unicorn_user:magical_password@localhost:5432/calendso

2. Run docker-compose up -d database

3. cd into /scripts

4. Three modes are available

• --bookings <n> — number of bookings per event type (default: 100)
• --start-from <n> — start user index for many-users mode (default: 0), enables resuming an interrupted run
• --till-user <n> — end user index for many-users mode (default: 20)
• --mode many-bookings | many-users — replaces the previously commented-out createManyDifferentUsers call

Examples

• npx ts-node --transpile-only ./scripts/seed-performance-testing.ts
• npx ts-node --transpile-only ./scripts/seed-performance-testing.ts --bookings 50
• npx ts-node --transpile-only ./scripts/seed-performance-testing.ts --mode many-users --till-user 100
• npx ts-node --transpile-only ./scripts/seed-performance-testing.ts --mode many-users --start-from 500 --till-user 1000

📝 Walkthrough

Walkthrough

This pull request refactors the performance testing seed script to support CLI-driven configuration and programmatic test data generation. It adds dotenv integration and a parseArgs() function that validates the --mode flag (many-bookings or many-users), parses numeric parameters (--bookings, --start-from, --till-user), and enforces constraint validation. The script's booking data generation is refactored from hardcoded object arrays to map()-generated arrays for yoga and tennis classes. The execution flow is reorganized with a new main() dispatcher function that routes to the appropriate seeding routine based on parsed arguments and returns proper exit codes.

Inline comments:
In `@scripts/seed-performance-testing.ts`:
- Around line 34-40: parseNonNegativeInt currently uses parseInt which accepts
truncated/ambiguous inputs (e.g. "10abc", "3.5"); change it to strictly validate
the raw string before conversion: require raw (or fallback string) to match the
integer-regex /^[0-9]+$/ (reject empty/negative/decimal/trailing chars), then
parse with Number or parseInt and ensure Number.isFinite and >= 0. Update
parseNonNegativeInt to accept the flag name (already present) and produce the
same exit/error behavior for invalid inputs; this will harden CLI flags like
--bookings, --start-from, and --till-user against malformed values.
