g6R 0.6.5

g6R 0.6.5

New features

• Bumped the bundled AntV G6 engine from 5.0.49 to 5.1.1 (with @antv/g 6.x and @antv/g-svg 2.1.1, deduplicating g-lite so the SVG renderer works again instead of throwing Cannot read properties of undefined (reading 'fill') on a blank canvas). The bump improves create-edge assist-line tracking under zoom/pan (G6 now derives the cursor position via getCanvasByClient()), fixes a combo/layout element-type confusion that crashed the canvas renderer when a combo was added at runtime under g6R.layout_on_data_change (Cannot read properties of undefined (reading 'src')), and pulls in upstream APIs (hasNode()/hasEdge()/hasCombo(), nested self-loop edges, drag-element trigger config). The widget bundle is now a single self-contained g6.js (the split 185.js chunk was removed).

• New placement = "label-bottom" for ports. When a node has a bottom label (e.g. labelPlacement = "bottom"), an output port with this placement snaps to the bottom-centre of the label background instead of the node body; it falls back to a normal bottom-of-node port when there is no label.

• Default port radius increased from 4 to 6 so ports are easier to see and target.

• Calmer port hover. Hovering a port no longer grows it ~2.5x into a rotating dashed + glyph (which read as flickering noise). Ports now keep their size and show a soft expanding ripple ring (in the port colour) only while the cursor is over them; the ripple stops when the cursor leaves. Disable it per port with ripple = FALSE. Ports also gain a background-coloured ring so they read as set into a small hole punched through the node / label surface (override with the haloFill port style), and the default fill adapts to the graph theme. The large invisible hit-area is kept, so ports remain easy to grab.

• Port hover cursor is now a crosshair instead of a pointer, matching G6's native create-edge affordance ("draw an edge from here"). The crosshair and the hover ripple only appear when the graph actually has the create_edge() behavior, so ports don't advertise an interaction that isn't wired up.

• create_edge() now tolerates a small miss when grabbing a port. Previously an edge only started when pointer-down landed exactly on the (small) port glyph; a near-miss on the node body fell through to drag_element() and moved the node instead. Pointer-down now snaps to the nearest grabbable port within a tolerance proportional to the port radius, so a slight miss still starts an edge (#50).

Bug fixes

• create_edge(): the hidden rubber-band assist node now carries a transparent src, so it no longer crashes the canvas renderer with Cannot read properties of undefined (reading 'src') when the consumer maps every node to an image node via a fixed node type. The node stays hidden, so the pixel is never shown. The SVG renderer is unaffected.

• Fixed create_edge() overwriting a consumer-supplied drag_element() / drag_element_force() enable predicate. While drawing an edge from a port, create_edge() pauses node dragging and resumes it on drop. It previously resumed by hardcoding enable: true, which destroyed any custom enable function after the first edge creation (and toggled behaviors via an array, a no-op in current G6 where updateBehavior() matches a single key). The live enable of each drag behavior is now snapshotted (looked up by type, so a custom key still works) and restored verbatim on drop (#48).

• Fixed the create_edge() rubber-band (assist) edge not appearing while dragging when the graph had no edge options configured. The assist edge style read graph.options.edge.style.zIndex, which threw and aborted assist-edge creation; it is now read defensively and falls back to G6's default.

• Fixed create_edge() drops being silently canceled below 100% browser zoom. The minimum drag-distance threshold was measured in canvas units, which scale with browser/graph zoom; below 100% a real drag shrank under the threshold and the drop was treated as a click. Drag intent is now measured in client (screen) pixels, which are zoom-stable (#52).

• Fixed the old + port indicator reappearing on node selection. The legacy indicator was replaced by the hover ripple, but its shapes were still created and G6's setVisibility() cascade (fired on selection/update) flipped them back to visible. The dead indicator shapes (add-inner, add-plus) and their animation helpers are now removed entirely, leaving only the ripple ring.
