Feature/dynamic services

Summary

Adds dynamic service count selection to the project scaffolding flow. Previously, the number of services was hardcoded to 5, which limited flexibility.
Closes #145.

Type of Change

• Bug fix
• Feature
• Chore / Refactor
• Docs
• Tests
• CI / Build

Motivation / Context

Currently, the CLI scaffolding process assumes there are always five services. This limits users who may want fewer or more services. This change makes the CLI prompt for the desired number of services before asking for the tech stack of each service, improving flexibility and usability.

Approach

• Added a new prompt asking the user: “How many services would you like to create?”
• Dynamically iterated over the number provided to ask for the tech stack of each service.
• Removed the hardcoded limit of 5 services in scaffoldMonorepo() logic.
• Ensured compatibility with existing templates and service generation flow.

CLI Impact

New prompt added — now asks for service count before individual tech stack inputs.
✅ Backward compatible (defaults to 5 if not specified in non-interactive mode).

Before:

node bin/index.js demo --services node --no-install --yes
# Always created 5 services

After:

node bin/index.js demo --services node --no-install --yes
# Prompts:
# How many services would you like to create? → 3
# Then asks tech stack for each of the 3 services

Generated Output Impact

• Updated generated structure to reflect dynamic number of service folders.
• Example: if user selects 3 services → creates /services/service1, /service2, /service3.
• Docker Compose and defaultPorts mapping dynamically adjusted to number of services.

Tests

Describe test coverage:

• Added new test(s) for variable service count.
• Updated existing scaffold tests.
• Manually smoke-tested locally.

Smoke test command:

node bin/index.js demo --services node --no-install --yes

Result: ✅ Successful generation with variable service counts (1–10 tested).

Screenshots / Logs (Optional)

✔ How many services would you like to create? 3
✔ Select tech stack for service #1: node
✔ Select tech stack for service #2: python
✔ Select tech stack for service #3: go
✨ Successfully created monorepo with 3 services!

Docs

Checklist

• Code follows existing style (chalk usage, emoji prefixes, exit codes).
• No large asset additions outside templates/.
• Default ports handled dynamically.
• New prompt validated for numeric input.
• Git history clean and rebased.
• Minimal dependencies added.
