[dependabot]

Bumps @mermaid-js/layout-elk from 0.2.3 to 1.0.0.

Release notes

Sourced from @​mermaid-js/layout-elk's releases.

@​mermaid-js/layout-elk@​1.0.0

Major Changes

• #8213 33442fd Thanks @​aloisklink! - chore!: require ES2024, Safari 17.4+, Node.JS v22.12+

  Mermaid is now built to target Safari 17.4+ and ES2024. If you need to support older browsers, you may need to polyfill or transpile mermaid.

  Safari 17.4+ has been chosen as the floor, as unlike Firefox/Chrome, older iOS devices don't get major Safari updates.

  Node.JS v22.12+ is also declared as requirement in our package.json files, but as mermaid requires a browser, this is mainly so we can use dependencies that also declare a Node.JS v22.12+ requirement, without causing issues for users when running npm install.

Minor Changes

• #8152 d4bea0d Thanks @​knsv-bot! - feat: elk.preset picks a named combination of the options that decide where nodes end up.

  Three options settle node positions, and they sit in different phases of the layout: which layer a node lands in, where it goes within that layer, and which edges get reversed to make the graph acyclic. Choosing them well means knowing all three interact; preset names the combinations worth using.

  • default — network simplex layering, balanced Brandes-Koepf placement at the top level and inside subgraphs, and depth-first cycle breaking. Balanced placement centres branches and composite-state entries; depth-first breaking gives shorter back edges on graphs that loop.
  • legacy — reproduces what earlier versions actually rendered: Brandes-Koepf placement with ELK's own greedy cycle breaking.
  • modelOrder — as depthFirst, but breaks cycles by greedy model order, which disturbs declaration order least at the cost of longer back edges.
  • depthFirst — the previous default: network simplex layering and top-level placement, Brandes-Koepf placement inside subgraphs, NONE alignment, and depth-first cycle breaking.

  ---
  config:
    layout: elk
    elk:
      preset: legacy
  ---

  Setting layeringStrategy, nodePlacementStrategy, nodePlacementAlignment or cycleBreakingStrategy explicitly overrides the preset for that one option and leaves the rest in place, so a preset is a starting point rather than a lock.

  Node placement keeps BRANDES_KOEPF, but its alignment changes from NONE to BALANCED and cycle breaking from GREEDY to DEPTH_FIRST, so existing ELK diagrams will lay out differently. preset: legacy restores the previous behaviour, and is the single switch for it — this is the net change against the last release, measured from what shipped rather than from any intermediate state.

  Subgraph contents use BRANDES_KOEPF under every preset. For modelOrder and depthFirst that is deliberately not the root's strategy: network simplex inside a frame produced routes that left the subgraph on its bounding-box corner. The two sides are tuned independently, so nodePlacementStrategy set explicitly still applies to both.

  Note that legacy uses GREEDY cycle breaking rather than the GREEDY_MODEL_ORDER the schema previously advertised. That default was declared in the schema but never listed in the shipped defaults, so it reached ELK as undefined and ELK's own default applied — legacy reproduces what was rendered, not what was documented.

• #8152 1246a55 Thanks @​knsv-bot! - feat: draw line hops where ELK edges cross, controlled by elk.lineHops.

  Where two edges cross, the one that gives way is drawn with a small arc (or a visible gap) so it is clear which line passes over which. On by default; set elk.lineHops: false to draw plain crossings, or 'gap' to use gaps instead of arcs.
