To activate your license and hide the watermark, you must set the go.Diagram.licenseKey property before creating any diagrams. javascript
// 1. Define your license key const myLicenseKey = "YOUR_LICENSE_KEY_HERE"; // 2. Initialize the diagram const $ = go.GraphObject.make; const diagram = $(go.Diagram, "myDiagramDiv", // Other diagram properties... ); // 3. Apply the license key diagram.licenseKey = myLicenseKey; Use code with caution. Best Practice: Setting the Key Globally
import * as go from 'gojs'; // 1. Set the license key immediately after importing GoJS // Replace the string below with your actual purchased key go.Diagram.licenseKey = "YOUR_COMMERCIAL_LICENSE_KEY_STRING_HERE"; // 2. Initialize your diagram as normal const myDiagram = new go.Diagram("myDiagramDiv", "undoManager.isEnabled": true, layout: new go.TreeLayout() ); // The canvas will now render seamlessly without any evaluation watermarks. Use code with caution. Why You Should Avoid Unofficial "Hacks"
Browsers frequently cache JavaScript files. If you recently added the license key but still see the watermark, clear your browser cache or test the application in an Incognito/Private window. Why You Should Avoid Technical Workarounds gojs remove watermark
If your project cannot afford a commercial GoJS license, or if you are building an open-source tool that cannot embed a proprietary paid key, your best path forward is to migrate to a fully open-source diagramming library.

Once your request is processed, Northwoods will generate a unique license key. Implementing it is straightforward. You must place the license key assignment loading the GoJS library but before creating your first diagram. To activate your license and hide the watermark,
If you have applied a valid license key but the watermark is still showing, check the following common issues:
It is important to acknowledge that a significant number of developers encountering this problem in their projects have attempted other approaches. Across platforms like CSDN, GitHub, Stack Overflow, and various programming forums, a common debate centers around removing the watermark by directly modifying the library's source code. The proliferation of technical guides on this topic suggests it is a subject of widespread interest, particularly among developers working on internal projects or in parts of the world where access to dollar-based payment systems is restricted.
Removing the GoJS watermark is an intentional step built into the library’s commercial lifecycle. To comply with software law and ensure application stability, always use a assigned to go.Diagram.licenseKey . For projects where licensing costs are prohibitive, choosing an open-source library from day one is the safest approach. If you are upgrading your architecture, let me know: Initialize the diagram const $ = go

It explicitly signals that the software is currently running under an evaluation or invalid license.
The go.Diagram.licenseKey property must be set before any go.GraphObject.make or new go.Diagram() calls occur. If a diagram initializes before the key is read, the watermark stays cached on that canvas.
