8.0.3 breaks line rendering with d3-transition

[rookuu]

Describe the bug
When updating to 8.0.3, some edges do not render and the following error is produced.

ERROR TypeError: linkSelection.attr(...).transition is not a function

This happens if you have multiple versions of d3-selection installed. The d3-transition package is attaching itself to a different version than what ngx is using. In my opinion, ngx-graph should list the d3 dependencies as peer dependencies to avoid this issue. However, we were able to work around it by "pinning" a single version of d3-selection. This can be done with npm or yarn. Here's what we did in package.json to get npm to pin a version:

"overrides": {
    "d3-selection": "3.0.0"
}

You can list the version that ngx-graph specifies, but 3.0.0 seems to work fine.

Here's an issue filed for d3 that kind of talks about the problem:

d3/d3#3262

We are also facing similar issue in using 8.0.3 with angular 15. Thanks @neodescis for suggesting a workaround, but unfortunately it did not resolved the issue for us. Greatly appreciate any additional recommendations.

Same error here (Angular 14). Had to rollback to ngx 8.0.2...

Same error here (Angular 14). Had to rollback to ngx 8.0.2...

this solved the issue.. it works

Did also see that issue, got it fixed with
"d3-selection": "^1.2.0",
npm i --legacy-peer-deps as it might be the wrong dependency for d3-transition

[bsarkadi]

I've had this issue on 8.2.1. This happens because ngx-graph has
"d3-selection": "^1.3.2" with "d3-transition": "^3.0.1" in the dependencies, but d3-transition 3.0.1 requires d3-selection 3.0.0.
The d3-selection version should be bumped to 3.0.0.

Meanwhile this workaround solves the issue in your app's package.json:

"overrides": {
"d3-selection": "3.0.0"
},

@neodescis this solution works for me in Angular 16. Thank u.

i am facing with the same issue, this its part of my package.json with dependecies that i have installed.
I am running an angular project version 16.2.9.

"@swimlane/ngx-graph": "^8.2.3",
"d3": "^7.8.5",
"d3-scale": "^4.0.2",
"d3-scale-chromatic": "^3.0.0",
"d3-selection": "3.0.0",
"d3-shape": "3.2.0",
"@types/d3": "^7.4.3",
"@types/d3-dispatch": "^3.0.6",

You put "override" atribute in your JSON file?

en mi caso tengo angular 17 y me funciona tener la versión 8.0.2 de ngx y de d3-selection la versión 3.0.10

hi @Kr0san89 .
I have angular version 13 and "@swimlane/ngx-graph": "8.2.1" installed. I did added
"overrides": {
"d3-selection": "3.0.0"
}

But still only one edge is rendering.

Also if i install this dependency as you mentioned - "d3-selection": "^1.2.0",

i am getting dependency conflict related warnings for 'd3-selection'.

Can you please provide any neat solution for this ? Thanks !

you can use npm i --legacy-peer-deps to get it installed.
To get rid of the `--legacy-peer-deps``you can use overrides see https://docs.npmjs.com/cli/v10/configuring-npm/package-json#overrides

As i don't use this override any more i'm not 100% sure, but something like

"overrides": { "@swimlane/ngx-graph": { "d3-selection": "1.2.0" } }

Can you please provide any neat solution for this ?

I created a PR to get d3 dependencies right #513 but unfortunately the maintainers did not merge it yet

hope this helps you

[jaykumarc]

Hi @Kr0san89 . I tried your given suggestion of adding overrides but no luck. only this thing is working for me - adding "d3-selection": "^1.2.0" as part of dependency (which is just giving dependency conflict related npm warnings).
Thank you so much for your help !
I hope that your pull request gets merged as soon as possible.
