In order to send data from a browser to a Node Red http input node, Node Red has to be configured to reply to CORS requests from the browser:

1. Go to Node Red Toolchain (IBM Cloud -> Resource List -> Developer Tools -> NODERED....)
2. Open GIT Repo for Node Red
3. Edit bluemix-settings.js
4. after functionGlobalContext: { }, add

  // The following property can be used to configure cross-origin resource sharing
  // in the HTTP nodes.
  // See https://github.com/troygoode/node-cors#configuration-options for
  // details on its contents. The following is a basic permissive set of options:
  httpNodeCors: {
    origin: "*",
   methods: "GET,PUT,POST,DELETE"
  },

1. Create a new empty toolchain
2. Add the GitHub tool, configure with github credentials and project URL
3. Add a Delivery Pipeline tool
   • add a build stage, builder type npm
     add at the end of the build script add:
     npm install
npm run build
   • add a deploy stage, deployer type Cloud Foundry
     NOTE: change the -name: XXX-iot in the manifest.yml file to your IOT organization name -> this will be the first part of the application URL!!! replace the deploy script with:
     #!/bin/bash
cp -v Staticfile build &&
cp -v manifest.yml build &&
cd build &&
cf push -f manifest.yml

This project was bootstrapped with Create React App.

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.

You can learn more in the Create React App documentation.
