QUESTION
I'm following the tutorial of the library go.js: https://www.youtube.com/watch?v=EyseUD_i6Dw&list=PLOiCuGu6tcUSvKsqFnemvGTfdT97wVLsX&index=3.
I reached this point without problems, but at this point I'm getting this error:

Answered 2022-Mar-17 at 12:10You have misspelled go.TextBlock
(you wrote go.textBlock

By the way, in 2.2 (which was released after those videos were made), GoJS has a new way of constructing objects that looks like this:
QUESTION
I'm trying to use GoJS to create some nodes using rounded rectangles and some text. This results in the following blurry rendering (at 100% zoom):
Not changing anything except opening the dev console (this acts like decreasing zoom it seems) results in the sharp image:
A similar look is achievable when zooming out to 80%. Is there any setting, ... I can adjust to get the crisp look at 100% zoom?
The same is true for the attribution text in the upper left corner:
...ANSWER
Answered 2022-Feb-21 at 01:00This might have to do with the pixel ratio, but it's not quite clear to me why.
You can query the pixel ratio GoJS uses by calling myDiagram.computePixelRatio()
in the console. This typically changes dynamically during drag operations.
You can customize the pixel ratio GoJS uses by setting it to a new function:
QUESTION
Is it possible to explicitly switch between dragging and linking modes in GoJS? I am trying to achieve a behavior similar to other diagram editors out there:
- Have 2 buttons in a toolbar outside of the diagram: an Link and a Hand.
- Clicking on Link button switches diagram into linking mode. Clicking any part of any node initiates LinkingTool on that node so it can be linked to another node. Node dragging is disabled.
- Clicking on Hand button switches diagram into dragging mode. Now mouse click on any node initiates DraggingTool, ResizingTool etc., anything but LinkingTool.
I believe I've seen such example but now cannot find it after couple hours of searching. An attempt to set diagram.toolManager.xxxTool.enabled to "false" in JavaScript does not seem to have any effect on tool activation behavior.
...ANSWER
Answered 2022-Feb-06 at 00:47I suspect your problem is just a typo, the property is isEnabled
, not enabled
.
For completeness: First you must set fromLinkable: true, toLinkable:true
(or at least one) on your Node or port to enable the linking tool. Then you can conditionally disable the tool via your button:
QUESTION
I was integrating gojs with react and was successfully able to integrated the nodes array and links array and was able to see the nodes in my page.
But the toughest thing , integrated ReactOverview (minimap) but i can see only small rectangle box on the page with no diagram in it.
Will share my code here
...ANSWER
Answered 2022-Jan-28 at 13:45The problem is that your component only renders once for the given props (any interactive diagram changes are handled internally by GoJS and React is oblivious to that). When it renders the first and only time, this.diagramRef.current
is still null
. You can see this if you log it in the render
method.
You need to use state to keep the "observed diagram" for the overview. Then when the overview component initializes, the diagram should be all set up and you can set the new state to cause re-render:
- Add the state with the value of the diagram you want to observe in the overview:

QUESTION
My application works fine with the tinylicious server, but I would like to consume routerlicious server without using deprecated experimental packages.
The server run in local docker container alfred run on port 3003)
My code to connect the client
...ANSWER
Answered 2021-Oct-29 at 23:57You're getting a 403 because your requests aren't authenticated (i.e. signed with a token that the Routerlicious service accepts). Tinylicious doesn't have auth, but Routerlicious does. The R11s auth model is very similar to the one used in Azure Fluid Relay, so the docs here are useful background:
https://docs.microsoft.com/azure/azure-fluid-relay/concepts/authentication-authorization
TL;DR summary of the auth model is that it's tenant-based; each tenant has a secret key that must be used to sign bearer tokens for the R11s service to accept the requests.
The R11s tenants are configured in the server/routerlicious/packages/routerlicious/config/config.json file here:
If you're using the R11s docker images, then you can use the default fluid
tenant ID with the tenant secret that's in the config file, along with InsecureTokenProvider. For example:

Can anyone give a help with this in PHP.
...ANSWER
Answered 2021-Oct-05 at 11:25For this type of problem, I can imagine that it's not easy to start off if you're learning programming. To solve this kind of problem in PHP, I would first convert the JSON to a PHP variable then build myself a dictionnary (kind of array with keys instead of contigus numerical indexes). This will help you have quick access to the data, typically to find the parents of a node entry.
You can also use recursion to get the parents of the parents, etc...
