In `@index.html`:
- Around line 97-111: The three select elements (priority-1, priority-2,
priority-3) currently allow duplicate categories; implement client-side logic to
enforce unique selections by listening for change events on these IDs and either
(a) disable the selected option value in the other two selects or (b) rebuild
their option lists to exclude already-chosen values, and also validate on form
submission to prevent duplicates; update the event handlers to re-enable options
when a selection is changed and ensure initial state handles defaults.
In `@README.md`:
- Line 64: Typo: the README sentence contains "assits" instead of "assists";
update the sentence fragment "we created a website that assits the passenger..."
to use the correct spelling "assists" so it reads "we created a website that
assists the passenger..." (keep the rest of the sentence unchanged).
- Line 7: The repository is missing the referenced .env.example file; add a new
.env.example file to the repo that lists all required environment variables (at
minimum JWT_SECRET, PORT, DB_PATH) with placeholder/example values and brief
comments, so developers can copy it to .env as instructed in README; ensure the
filename matches exactly ".env.example" and include any other env keys used by
startup code (search for usages of process.env.JWT_SECRET, process.env.PORT,
process.env.DB_PATH, etc.) to document them in the example file.
In `@script9.js`:
- Around line 25-46: The apiRequest function currently re-throws any exception
from fetch/raw network failures without a consistent shape, so callers that read
err.status/err.body get undefined; modify apiRequest to normalize all errors
into a consistent object (e.g., { status: 0, body: <error message or original
error> } for network/fetch exceptions) and still preserve HTTP error objects
thrown when res.ok is false; specifically update the catch block in apiRequest
(which wraps fetch/API_BASE) to detect when no Response was received and throw a
normalized error with status and body properties (and include the original error
under a field like cause) so callers that check err.status/err.body behave
deterministically.
- Around line 383-389: The code builds HTML via string interpolation into the
listHtml constant using it.destination which allows XSS; sanitize or escape the
destination before inserting into the template (or avoid innerHTML by creating
DOM nodes). Modify the mapping that produces listHtml (the arrow function that
builds the template string) to escape dangerous characters in it.destination (or
use a helper escapeHtml function) and ensure the resulting string is safe when
assigned to innerHTML, keeping viewItinerary("${it.id}") unchanged but ensure id
is also validated/escaped if used in HTML context.
- Around line 67-97: The code currently treats any 401 in the initial login flow
as "user not found" and auto-attempts registration; change this to avoid
misfires by either (A) checking the server error payload (err.body?.error?.code
or err.body?.error?.message) and only invoking the registration branch when the
error explicitly indicates user-not-found, or (B) removing the automatic
registration branch entirely and instead surface a clear UI pathway to call
apiRequest('/auth/register', 'POST', ...) from an explicit registration action;
update the catch block around the initial login (the try/catch that references
apiRequest, authToken, localStorage, currentUser,
document.getElementById('display-username'), and showSection) so it no longer
attempts registration on every 401 unless the error body proves the user is
missing.
- Around line 349-376: renderItinerary currently injects server-provided fields
directly into a template string assigned to container.innerHTML (e.g.,
i.morning.place, i.e., i.evening.type, i.afternoon.place), which is an XSS
vector; change the implementation to build DOM nodes and set user data with
textContent (or run a proper sanitizer) instead of string
interpolation—specifically, stop using container.innerHTML += dayHTML, create
the outer day element (matching the structure in dayHTML), fill titles and
place/type values via element.textContent for i.day, i.morning.type,
i.morning.place, i.afternoon.type, i.afternoon.place, i.evening.type,
i.evening.place, and append the element to container to eliminate executing any
HTML in server data.
In `@src/config.js`:
- Line 9: The current jwtSecret fallback ('change_this_in_production') is
insecure: update the config logic that builds jwtSecret so that if
process.env.NODE_ENV === 'production' and process.env.JWT_SECRET is falsy the
app throws an Error (or exits) with a clear message instead of silently using
the hardcoded default; keep a non-production fallback only for dev/test. Modify
the jwtSecret assignment in src/config.js to validate process.env.JWT_SECRET and
raise an error in production, and ensure any code that imports this config
(jwtSecret) will fail fast on startup when misconfigured.
In `@src/db/index.js`:
- Around line 11-17: The current getDb() caches the raw open() promise in
dbPromise so if open() rejects the rejected promise is permanently stored;
change getDb() to assign dbPromise = open(...) then await it inside a try/catch
(use await dbPromise), and on catch reset dbPromise = null before rethrowing the
error so subsequent calls will retry; reference the getDb function, the
dbPromise variable, and the open(...) call when making the change.
In `@src/db/init.js`:
- Around line 15-24: Add a FOREIGN KEY constraint to the itineraries table
creation so itineraries.user_id references users(id) (e.g., ALTER the CREATE
TABLE itineraries statement to include "FOREIGN KEY(user_id) REFERENCES
users(id) ON DELETE CASCADE" or equivalent) to prevent orphaned rows, and enable
SQLite foreign key enforcement by executing PRAGMA foreign_keys = ON after
opening the DB in the getDb function (where dbPromise is created) in
src/db/index.js so the constraint is enforced at runtime.
In `@src/index.js`:
- Line 28: The current call app.use(express.static(process.cwd())) exposes the
entire project root (including .env, DB, config and source); change the static
middleware to serve only a dedicated public assets directory (e.g., replace the
express.static(process.cwd()) usage in your server bootstrap where app.use(...)
is called with a static serve pointing to a single public folder), move all
frontend assets (index.html, scripts, styles) into that folder, and ensure
sensitive files (env, DB, config) are excluded from served content and not
located under that public directory.
In `@src/middleware/errorHandler.js`:
- Around line 3-11: The errorHandler middleware currently returns err.message
for all errors which can leak internals for 5xx responses; update errorHandler
to always log the full error via logger.error(err) but when computing the JSON
response use a generic message (e.g., "Internal Server Error") if err.status is
500 or >=500 (or if err.expose is false), and only include err.message for
client/expected errors (status < 500 or an explicit expose flag). Keep using the
existing symbols errorHandler, logger.error(err), err.status, and
res.status(...).json(...) so the change simply selects the response message
based on err.status/err.expose while preserving full logging.
In `@src/routes/auth.js`:
- Line 43: The code uses the blocking bcrypt.compareSync call (const ok =
bcrypt.compareSync(password, row.password)); replace it with the non-blocking
async bcrypt.compare: make the enclosing handler function async (or return a
Promise), await bcrypt.compare(password, row.password), and handle errors;
update the variable 'ok' to receive the awaited result and proceed with the same
success/failure flow (including early returns) so the event loop is not blocked.
- Line 19: Replace the blocking bcrypt.hashSync call with the asynchronous
bcrypt.hash in the auth route: make the route handler async (or return a
Promise), call await bcrypt.hash(password, 10) instead of
bcrypt.hashSync(password, 10), and handle errors with try/catch so failures to
hash are caught and logged/responded to rather than crashing the request; update
any references to the synchronous "hashed" assignment accordingly (e.g., where
"hashed" is used to create the user or compare later).
In `@src/routes/itineraries.js`:
- Around line 8-12: The priorities array in createSchema currently allows any
three strings, causing generateItineraryItems to receive invalid keys and
produce generic placeholders; update createSchema's priorities validation to
restrict values to the known activity categories used by generateItineraryItems
(e.g., "Food Spots", "Tourist Spots", "Shopping" — or whatever exact category
strings generateItineraryItems expects) by replacing Joi.string() with
Joi.string().valid(...) inside the priorities array schema while keeping
.length(3). Ensure the valid list matches the keys used in
generateItineraryItems so invalid submissions are rejected.
In `@src/server.js`:
- Around line 13-16: app.listen's bind errors are emitted on the returned server
object, not thrown into the surrounding try/catch; change the call to capture
the server handle (e.g., const server = app.listen(port, () => {
logger.info(...); })) and attach an error listener on that handle
(server.on('error', err => { logger.error('Server failed to start', err); handle
specific cases like err.code === 'EADDRINUSE' and exit or retry as appropriate
})), ensuring you log the real error details rather than relying only on the
callback.
In `@style9.css`:
- Around line 107-117: The .page-section transition won't run because switching
from display: none to display: flex prevents CSS transitions; update the
approach so the element stays in layout and only visibility/opacity/transform
change: keep .page-section as display: flex (or block) always, change the
inactive state to visibility: hidden; pointer-events: none; opacity: 0;
transform: translateY(20px); and have .page-section.active set visibility:
visible; pointer-events: auto; opacity: 1; transform: translateY(0) so the
opacity/transform transitions run; alternatively, if you must toggle display,
modify the JavaScript that adds .page-section.active (or sets display) to first
set display: flex, then add .active on the next animation frame (using
requestAnimationFrame or a minimal setTimeout) so the transition can start.

Priority dropdowns allow duplicate selections.
All three <select> elements share the same options and can independently be set to the same value (e.g., "Food Spots" for all three priorities). This would produce a broken itinerary with only one category. Add client-side validation or dynamically filter chosen values from subsequent dropdowns.

apiRequest does not handle network failures distinctly from HTTP errors.
When fetch itself throws (e.g., network offline, DNS failure), the catch block re-throws an error without status or body properties. Callers that inspect err.status (line 70) will see undefined, potentially triggering unintended auto-registration. Consider normalizing the error shape.

Auto-register on 401 misfires when the password is wrong for an existing user.
The backend returns 401 for both "user not found" and "wrong password". This code interprets any 401 as "user not found" and attempts registration, which then fails with a 409 ("Username already exists"), producing a confusing error. Either differentiate the server's 401 responses or remove the auto-register behavior and provide explicit register/login flows.

Priorities are not validated against known activity categories.
The priorities array accepts any 3 strings, but generateItineraryItems uses them as keys to look up city data (e.g., "Food Spots", "Tourist Spots", "Shopping"). If a user submits arbitrary strings, every activity falls back to the generic "${activityType} near ${destination}" placeholder. Consider adding .valid() to constrain allowed values:

In `@src/routes/itineraries.js` around lines 8 - 12, The priorities array in
createSchema currently allows any three strings, causing generateItineraryItems
to receive invalid keys and produce generic placeholders; update createSchema's
priorities validation to restrict values to the known activity categories used
by generateItineraryItems (e.g., "Food Spots", "Tourist Spots", "Shopping" — or
whatever exact category strings generateItineraryItems expects) by replacing
Joi.string() with Joi.string().valid(...) inside the priorities array schema
while keeping .length(3). Ensure the valid list matches the keys used in
generateItineraryItems so invalid submissions are rejected.

Port-in-use errors won't be caught by the try/catch.
app.listen() is callback-based; bind errors (e.g., EADDRINUSE) are emitted as 'error' events on the returned server object, not thrown into the surrounding try/catch. Consider capturing the server handle and attaching an error listener.

- app.listen(port, () => {
+ const server = app.listen(port, () => {
logger.info(`Server listening on port ${port}`);
console.log(`Server listening on port ${port}`);

In `@src/server.js` around lines 13 - 16, app.listen's bind errors are emitted on
the returned server object, not thrown into the surrounding try/catch; change
the call to capture the server handle (e.g., const server = app.listen(port, ()
=> { logger.info(...); })) and attach an error listener on that handle
(server.on('error', err => { logger.error('Server failed to start', err); handle
specific cases like err.code === 'EADDRINUSE' and exit or retry as appropriate
})), ensuring you log the real error details rather than relying only on the
callback.

Page transition animation won't work due to display: none → display: flex toggle.
CSS transitions on opacity and transform do not fire when display changes from none to flex, because the element is not in the layout to begin with. The page will just snap into view without the intended fade/slide.
A common fix is to separate the display toggle from the animation trigger — e.g., set display: flex first, then add the active class on the next frame (via requestAnimationFrame or a minimal setTimeout in JS), or use visibility/pointer-events instead of display: none.

In `@style9.css` around lines 107 - 117, The .page-section transition won't run
because switching from display: none to display: flex prevents CSS transitions;
update the approach so the element stays in layout and only
visibility/opacity/transform change: keep .page-section as display: flex (or
block) always, change the inactive state to visibility: hidden; pointer-events:
none; opacity: 0; transform: translateY(20px); and have .page-section.active set
visibility: visible; pointer-events: auto; opacity: 1; transform: translateY(0)
so the opacity/transform transitions run; alternatively, if you must toggle
display, modify the JavaScript that adds .page-section.active (or sets display)
to first set display: flex, then add .active on the next animation frame (using
requestAnimationFrame or a minimal setTimeout) so the transition can start.
