If you wish to use the GoJS library for your private evaluation, you may do so only under the terms of the Evaluation License Agreement.
You can download the whole web site for this version of GoJS by saving and unzipping:
We also maintain a GitHub Repository of all libraries, documentation, samples, and extensions. This allows you to search through documentation and code online.
The contents of both the ZIP file and the GitHub repository are exactly what you find at the GoJS web site. Having everything downloaded to your development machine allows you to easily search the JavaScript code and to modify the samples for experimentation.
You can also download GoJS via Node package manager (npm):
$ npm install gojs --save.
Or download the GoJS library files via NuGet:
PM> Install-Package Northwoods.GoJS.
Or you can link to a CDN.
The GoJS library comes in both "debug" and "release" variations in the release directory:
We recommend that you use go-debug.js while doing your initial development --
it is more likely to signal errors or provide meaningful error messages than when using go.js.
Always remember to look at the console log to see if there are any error or warning messages.
After purchasing a license, you may deploy by acquiring a license key for your web site's domain. See Deployment for more discussion.
When upgrading to a newer version, please read the Change Log. In addition to getting new debug and release libraries, don't forget to use the latest TypeScript definition file, go.d.ts, that is also in the release directory.
