src/simulator/src/data/project.ts (1)
158-178: Refactor: Improve error handling and separation of concerns.The function mixes multiple responsibilities and lacks proper error handling for asynchronous operations.
Consider breaking down the function into smaller, focused functions:
async function confirmNewProject(verify: boolean): Promise<boolean> { if (!verify && !projectSaved && checkToSave()) { return confirmOption( 'What you like to start a new project? Any unsaved changes will be lost.' ) } return true } async function resetProjectState(): Promise<void> { await clearProject() localStorage.removeItem('recover') setProjectName(undefined) projectId = generateId() } async function navigateToNewProject(): Promise<void> { const baseUrl = window.location.origin !== 'null' ? window.location.origin : process.env.BASE_URL || 'http://localhost:4000' const url = new URL('/simulatorvue/', baseUrl) window.location.assign(url.toString()) } export async function newProject(verify: boolean): Promise<void> { try { const confirmed = await confirmNewProject(verify) if (!confirmed) return await resetProjectState() await navigateToNewProject() showMessage('New Project has been created!') } catch (error) { showError('Failed to create new project') throw error } }src/simulator/src/data/load.ts (1)

5-5: Consider using an enum for 'type' in 'Device' interfaceCurrently, the
typeproperty in theDeviceinterface is defined as a union of string literals'Input' | 'Output' | 'Memory'. Consider using an enum to define device types for better scalability and maintenance.Example:
enum DeviceType { Input = 'Input', Output = 'Output', Memory = 'Memory', } interface Device { type: DeviceType; // rest of the properties... }

43-248: Variable 'js' is defined but not usedThe constant
jsof typeCircuitis defined but not used within this file. This may lead to unused variable warnings and indicates potential dead code.If
jsis needed in future implementations, consider using it within this file. Otherwise, remove it to clean up the code.src/components/Panels/ElementsPanel/ElementsPanel.vue (2)
43-43: Display element names in search results for consistencyIn the search results, the element names are not displayed under the images. For consistency and better user experience, consider adding the element names similar to how it's done in the main panel.
Add the following code after the image tag in the search results section:
<div class="overflow-hidden text-nowrap position-relative"> <p class="d-inline-block">{{ element.name }}</p> </div>
81-81: Display element names in search categories for consistencyIn the expanded search categories, the element names are not displayed under the images. To maintain consistency across the UI, consider adding the element names.
Add the following code after the image tag in the search categories section:
<div class="overflow-hidden text-nowrap position-relative"> <p class="d-inline-block">{{ element.name }}</p> </div>

Security & Reliability: Improve URL handling.
The URL construction has potential issues:
- Hardcoded localhost URL could cause problems in different environments
- Direct string concatenation for URLs is error-prone
Consider this safer approach:
- const baseUrl = window.location.origin !== 'null' ? window.location.origin : 'http://localhost:4000'
- window.location.assign(`${baseUrl}/simulatorvue/`)
+ const baseUrl = window.location.origin !== 'null' ? window.location.origin : process.env.BASE_URL || 'http://localhost:4000'
+ const url = new URL('/simulatorvue/', baseUrl)
+ window.location.assign(url.toString())Committable suggestion skipped: line range outside the PR's diff.

Critical: Restore unsaved changes protection mechanism.
Commenting out the window.onbeforeunload handler removes critical user experience safeguards:
- Users can now lose unsaved work without warning
- The automatic recovery mechanism is disabled
- This contradicts standard web practices for handling unsaved changes
Consider this improved implementation:
- // window.onbeforeunload = async function () {
+ window.onbeforeunload = function (e: BeforeUnloadEvent) {
+ if (projectSaved || embed) return undefined
+
+ if (!checkToSave()) return undefined
+
+ // Modern browsers require us to set returnValue
+ const message = 'You have unsaved changes. Are you sure you want to leave?'
+ e.returnValue = message
+
+ // Asynchronously save recovery data
+ void (async () => {
+ const data = await generateSaveData('Untitled')
+ localStorage.setItem('recover', JSON.stringify(data))
+ })()
+
+ return message
+ }This implementation:
- Uses TypeScript types
- Follows modern browser standards
- Handles async operations correctly
- Preserves the recovery mechanism

Undefined reference to 'fixDirection'
The variable fixDirection is not defined or imported, but it's used in oppositeDirection[fixDirection[obj.direction]]. This will cause a runtime error.
Ensure that fixDirection is defined or imported before using it. If it's meant to be a method, consider calling it appropriately.

Undefined variable '__projectName'
The variable __projectName is used but not defined or imported in this file. This will lead to a runtime error when setProjectName(__projectName) is called.
Define or import __projectName before using it, or ensure it's available in the current scope.

Undefined variable 'embed'
The variable embed is used in the conditional statement but is not defined or imported in this file. This will cause a runtime error.
Define or import embed before using it, or check if it's intended to be a global variable accessible in this context.
