dagre.layout() options not taken into account

[loicknuchel]

Hi,

I'm integrating dagre into https://github.com/azimuttapp/azimutt (an ERD tool) and it looks like when I change options in the dagre.layout function, I still get the same result 😅
I followed the https://github.com/dagrejs/dagre/wiki#an-example-layout, here is my code:

const g = new dagre.graphlib.Graph()
g.setGraph({})
g.setDefaultEdgeLabel(() => ({}))
nodes.forEach(n => g.setNode(n.id, {width: n.size.width, height: n.size.height}))
edges.forEach(e => g.setEdge(e.src, e.ref))
dagre.layout(g, {rankdir: 'LR', nodesep: 20, edgesep: 0, ranksep: 20}) // these options don't change anything, tried LR, TB, BT... rankdir and more :/
app.gotAutoLayout(g.nodes().map(id => {
    const node = g.node(id)
    return {id, size: {width: node.width, height: node.height}, pos: {left: node.x, top: node.y}}
}))

Any idea why?

Also, is there a way to "freeze" existing nodes? When I'm adding a new entity (in my ERD), I want to get a good position for it but not change anything else. Is it possible with dagre?

Thanks!
