Overview
A React component that manages and displays the collection of open editor tabs with add tab functionality.
Description
EditorTabs is a React component that serves as the tab bar for the code editor, displaying all open tabs and providing controls for tab management. It separates tabs into local tabs (custom SQL queries) and remote tabs (project files) and displays them with appropriate titles. The component includes a plus button to create new custom SQL tabs and implements intelligent tab replacement logic to avoid cluttering the tab bar when switching between files.
The component manages the lifecycle of editor tabs, automatically creating new tabs when files are selected and determining whether to replace the current tab or add a new one based on the tab's state. It implements smart tab replacement where unchanged remote file tabs are replaced when selecting a new file, while changed tabs are preserved. The component also handles persistent state for the last selected model, allowing the UI to restore the previously active model when returning to the editor.
Usage
Use this component as the tab bar at the top of the code editor to display and manage all open editor tabs. It automatically handles tab creation, selection, and lifecycle management based on user interactions and file selections.

Tab Management Logic
Tab Creation and Replacement
The component implements intelligent tab replacement:
const shouldReplaceTab =
isNotNil(tab) &&
tab.file instanceof ModelFile &&
isFalse(tab.file.isChanged) &&
tab.file.isRemote &&
isFalse(tabs.has(selectedFile))
if (shouldReplaceTab) {
replaceTab(tab, newTab)
} else {
addTab(newTab)
}
Tab Separation
Tabs are separated into two groups:
const [tabsLocal, tabsRemote] = useMemo(() => {
const local: EditorTab[] = []
const remote: EditorTab[] = []
tabs.forEach(tab => {
if (tab.file.isLocal) local.push(tab)
if (tab.file.isRemote) remote.push(tab)
})
return [local, remote]
}, [tabs])
- Local Tabs: Custom SQL queries numbered as "Custom SQL 1", "Custom SQL 2", etc.
- Remote Tabs: Project files displayed with their actual file names
Add Tab Button
The plus button creates new custom SQL tabs:
function addTabAndSelect(): void {
const tab = createTab()
addTab(tab)
selectTab(tab)
setSelectedFile(tab.file)
}
Last Selected Model
The component maintains state for the last selected model:
- Stores the last selected model when switching files
- Restores the last selected model when returning to the editor
- Helps preserve user context across navigation
