Summary

  • Adds --no-ui flag to code-iq serve that disables the React SPA while keeping REST API and MCP endpoints fully active
  • Useful for headless/CI environments where only the API or MCP server is needed
  • Implements @ConditionalOnProperty on SpaController so it is excluded from the Spring context when codeiq.ui.enabled=false
  • Pre-context system property is set in CodeIqApplication.main() before Spring initializes (same pattern as --port and --graph flags)
  • Startup log clearly reports UI status: enabled URL or "disabled (API and MCP active at :PORT)"

Changes

  • CodeIqApplication.java — detect --no-ui arg and set codeiq.ui.enabled=false system property before Spring context
  • SpaController.java — add @ConditionalOnProperty(name = "codeiq.ui.enabled", havingValue = "true", matchIfMissing = true)
  • CodeIqConfig.java — add uiEnabled field bound to codeiq.ui.enabled
  • application.yml — default codeiq.ui.enabled: true
  • ServeCommand.java — add --no-ui option; differentiated startup log
  • ServeCommandTest.java — 2 new tests (noUiDefaultsToFalse, noUiFlagIsRecognized)
  • SpaControllerConditionalTest.java — 5 new tests verifying annotation metadata and conditional bean registration

Test plan

  • ServeCommandTest — 7 tests, all pass
  • SpaControllerConditionalTest — 5 tests: verifies bean absent when codeiq.ui.enabled=false, present when true or absent
  • Full suite: 1447 tests, 0 failures

Acceptance criteria met

  • code-iq serve --no-ui /path/to/repo starts without registering SpaController
  • GET /topology, /explorer etc. return 404 when --no-ui is active (SpaController not registered)
  • GET /api/stats still works when --no-ui is active
  • GET /mcp still works when --no-ui is active
  • code-iq serve /path/to/repo (without flag) works as before
  • Startup log clearly states whether UI is enabled
  • All existing tests pass

Closes RAN-52

Code Review: PR #11 — --no-ui Flag

Verdict: Changes requested (2 blocking, 2 warnings)

BLOCKING

1. Domain boundary violation — frontend files in a Backend Engineer PR

This PR includes commit 482ca24 (the frontend treemap change from PR #10). The diff contains 15+ frontend files (src/main/frontend/**, src/main/resources/static/**). Per policy, a Backend Engineer PR must contain only backend files.

Fix: Rebase so this branch starts from main (not from the frontend feature branch). Only commits ddcd713 and 9f12558 should be in this PR.

2. extractPositionalArg bug — --no-ui consumes the next argument

CodeIqApplication.java lines 155-158:

if (arg.startsWith("--") && !arg.contains("=")) {
    skipNext = true;
    continue;
}

This treats ALL --flag arguments as key-value pairs. When a user runs code-iq serve --no-ui /my/repo, the path /my/repo is consumed as if it were the value of --no-ui, causing Neo4j to default to the current directory instead of the specified repo.

Fix: Maintain a set of known boolean flags (--no-ui, --verbose, etc.) and don't set skipNext for them.

WARNINGS

3. CodeIqConfig.uiEnabled not synced at runtime

ServeCommand has its own boolean noUi field and CodeIqConfig has boolean uiEnabled. The system property path controls @ConditionalOnProperty, but code reading config.isUiEnabled() at runtime will always see true unless Spring refreshes from the system property. Either remove uiEnabled from CodeIqConfig if it's only needed for conditional bean registration, or explicitly sync it in ServeCommand.call().

4. staticResourcesDisabledWhenUiDisabled test name overstates its assertions

SpaControllerConditionalTest.java lines 61-69 — the test name implies static resources are disabled, but it only checks that SpaController is absent. Consider asserting that spring.web.resources.add-mappings=false is effective.

Correct & Well Done

  • @ConditionalOnProperty annotation on SpaController is correct: name = "codeiq.ui.enabled", havingValue = "true", matchIfMissing = true
  • System property timing is correct — set in main() before app.run(args)
  • Config binding in CodeIqConfig matches Spring relaxed binding (codeiq.ui.enabled → uiEnabled)
  • API/MCP unaffected — SpaController only handles UI routes; REST/MCP beans are unconditional within the serving profile
  • Static resource fix in commit 9f12558 correctly sets spring.web.resources.add-mappings=false
  • Tests pass — 7 ServeCommandTest + 7 SpaControllerConditionalTest all green
  • ApplicationContextRunner used instead of @SpringBootTest — avoids Neo4j startup cost
  • SPA routes updated — /topology and /flow correctly replaced with /graph

feat: add --no-ui flag to serve command to disable web UI at launch
79b0016 
When --no-ui is passed to `code-iq serve`, the React SPA is excluded
and only the REST API and MCP server remain active. Useful for headless
or CI environments.

- CodeIqApplication.main() detects --no-ui before Spring context init
  and sets codeiq.ui.enabled=false as a system property
- SpaController gains @ConditionalOnProperty so it is only registered
  when codeiq.ui.enabled=true (default: true / matchIfMissing=true)
- CodeIqConfig gains uiEnabled field bound to codeiq.ui.enabled
- application.yml sets codeiq.ui.enabled: true as default
- ServeCommand: added --no-ui option; startup log now states whether
  Web UI is enabled or disabled
- Tests: 2 new --no-ui flag tests in ServeCommandTest, 5 new
  SpaControllerConditionalTest tests (1447 total, 0 failures)

- CodeIqApplication: set spring.web.resources.add-mappings=false when --no-ui
  is active, preventing static file serving (index.html, JS, CSS bundles)
- SpaController: replace stale /topology and /flow routes with /graph (matches
  the current Code Graph treemap tab added in 482ca24)
- SpaControllerConditionalTest: add staticResourcesDisabledWhenUiDisabled test
  and spaControllerExplicitRoutesContainGraph test (1449 total, 0 failures)

…-no-ui flag

The arg parser incorrectly set skipNext=true for ALL --flag patterns, causing
code-iq serve --no-ui /repo to silently drop /repo (treating it as the value
of --no-ui). Boolean flags that take no value must not consume the next token.

- Added BOOLEAN_FLAGS set (--no-ui, --help, -h, --version) to CodeIqApplication
- extractPositionalArg now skips skipNext for flags in BOOLEAN_FLAGS
- Added pathNotSwallowedWhenNoUiPrecedesPath test to ServeCommandTest
- Added CodeIqApplicationArgParsingTest with 5 reflection-based unit tests
  for extractPositionalArg edge cases
