By Northwoods Software for GoJS 2.1

This project provides a basic example of using GoJS in a React app. Check out the Intro page on using GoJS with React for more information.

It makes use of the gojs-react package to handle some boilerplate for setting up and tearing down a Diagram component.

When running the sample, try moving around nodes, editing text, relinking, undoing (Ctrl-Z), etc. within the diagram and you'll notice the changes are reflected in the inspector area. You'll also notice that changes made in the inspector are reflected in the diagram. If you use the React dev tools, you can inspect the React state and see it updated as changes happen.

For additional samples, see gojs-react-samples.

This project was bootstrapped with Create React App. It also uses immer to simplify state update operations.


Start by running npm install to install all necessary dependencies.

Available Scripts

In the project directory, you can run:

npm start

Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser.

The page will reload if you make edits.
You will also see any lint errors in the console.

npm run build

Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.

The build is minified and the filenames include the hashes.
Your app is ready to be deployed!

See the section about deployment for more information.

npm run eject

Note: this is a one-way operation. Once you eject, you can’t go back!

If you aren’t satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.

Instead, it will copy all the configuration files and the transitive dependencies (Webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.

You don’t have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
