Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to The sidebar now renders collection trees as virtualized flat rows, reducing resource use for large collections. Remaining test-helper issues can make navigation and tree assertions unreliable, potentially masking regressions in collection operations and virtualized sidebar behavior; these should be resolved before merge.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Use a virtualization-aware lookup for collection rows.
revealCollectionsTop(page) only resets the Virtuoso list to the top. It does not render collections outside the viewport and overscan range. If the requested collection is lower in the list, its row remains unmounted, so openRequest, openfolder, and openFolderRequest wait for a row that cannot be clicked and time out. Scroll [data-testid="sidebar-collections-scroller"] until the requested row mounts before clicking it in all three helpers.

💡 Result:
Based on available documentation and source code from the Bruno API client repository, there is no public or documented function named expandAllFolders or getCollectionTreeStructure as part of the core API [1][2][3][4]. The terms you are inquiring about appear to relate to internal project discussions or specific implementation patterns within the Bruno codebase: 1. expandAllFolders: This concept has been requested by the community as a feature to expand or collapse all folders in a collection [1]. While some users have proposed pull requests to implement this, the maintainers have indicated it is not currently a priority and have not accepted those changes, resulting in the feature remaining unavailable in the core application [1][5]. In the project's test suite, there is a helper function named expandFolder used for automated testing (via Playwright) to expand individual folders [2][6], but this is not a general-purpose API for end users. 2. getCollectionTreeStructure: There is no public function with this exact name in the Bruno API. The codebase uses internal utility functions related to managing tree paths, such as getTreePathFromCollectionToItem, which handles mapping the relationship between a collection and its items [3]. These are internal methods used for managing the application's internal state rather than exposed methods for users [2][3]. In summary, neither function exists as a public API or feature in Bruno; they are either requested features or internal implementation details [1][3].

Traverse the complete virtualized sidebar before rebuilding the tree.
The sidebar renders collection rows through Virtuoso, so allRows().all() snapshots only rows currently mounted in the DOM. expandAllFolders also stops after 200 clicks without checking for remaining collapsed folders. If traversal needs more than 200 clicks or rows are outside the viewport, getCollectionTreeStructure can omit items. Scroll through the virtualized list, await expansion state instead of using a fixed delay, and fail when traversal is incomplete.

Description
Virtualizes the collections sidebar so it renders only the rows currently in view instead of the entire nested tree.
It keeps render cost flat no matter how many collections, folders, requests, or examples exist.
Added the missing tests here #8891
Problem
The old sidebar rendered the collection tree recursively so every collection, folder, request, and example are mounted even though they are not in the viewport Rendering cost scaled with the total number of items, so large collections were slow and heavy.
Benefits After Refactor
Fix
Used virtuoso to virtualize the sidebar items. Since virtuoso works on flat data, we are flattening the sidebar nested data and feeds it to virtuoso. Now the rows which are currently visible on viewport are mounted and in the DOM. Also added a overlook scan to avoid a flicker on fast scroll.
This fixes problems with slow typing in Editors, codemirrors whenever user have large number of items in the sidebar.
Used four maps to store the data and for fast lookup
The object maps: itemsByUid / collectionsByUid: These map a uid to the live folder/app/request or collection object in the Redux store.
Rows are structural only, a row carries id, kind, depth, uids, sortName, parentName, but not the actual object. Since Rows are rebuilt on every flatten, and if each row embedded the full item object, then (a) rows would be fat, and (b) memoization would be hard.
The index maps: rowIndexByItemUid / rowIndexByCollectionUid: These map a uid to the row's position (its integer index in the rows array), and they exist for exactly one feature: scroll-to-active-tab.
Changes
utils/collections/flattenSidebarTree.js: This contains the functions to flat the sidebar nested items.flattenSidebarTree: This takes the nested sidebar items and returns a flat row containing all items.flattenCollection: Adds a collection and its visible children to the flat sidebar row list.walkChildren: Flattens the children of a collection or folder into sidebar rows.Sidebar/Collections/index.js: This used theflattenSidebarTreefunction and feed the flat rows toVirtuoso.It renders the rows using
SidebarRowcomponent.SidebarRow/index.jsx: This renders the items using theitemsByUid, collectionsByUidmaps. Based on the kind of row item it maps them to the right presentation componentCollectionRow, CollectionItemRow, EmptyCtaRow, ExampleItem, GitRemoteCollectionRow).slices/collections/index.js: Since Virtuoso unmounts offscreen rows, per-row "examples expanded" React state wouldn't survive a scroll. Added the toggleRequestExamples reducer and an examplesExpanded flag on the item so expansion state lives in the store and examples are emitted as their own flat rows.Test-side changes: the DOM is now flat, every helper and spec that relied on nesting (.locator('..'), #collection- descendant scoping) was rewritten to scope by data-collection-id/data-parent-name.Screenshots
