This project was bootstrapped with Create React App. It is to provide an example React application connecting to Deephaven and displaying a table of data.
- Start the server: Following instructions on GitHub to run deephaven-core with python: https://github.com/deephaven/deephaven-core/#run-deephaven.
- Install dependencies: Run
npm installto install all dependencies required. - Start the UI: Run
npm startto start up the UI. It should automatically open up at http://localhost:3000 and load up a table.
See the guide for how to set up core in Application Mode: https://deephaven.io/core/docs/how-to-guides/app-mode/
Once Deephaven is running, you can open a table with a specific name by adding the query param tableName, e.g. http://localhost:3000/?tableName=world
By default, this project assumes you are hosting Deephaven with Python on the default port at http://localhost:10000. If Deephaven is running on a different port/server, update the REACT_APP_CORE_API_URL environment variable to point to the correct server. See .env file for the default definition, and create-react-app docs for other ways to set this environment variable.
In the project directory, you can run:
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.
Launches the test runner in the interactive watch mode.
See the section about running tests for more information.
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.
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.
