✔️Use different Google Cloud projects if you need separate quotas for each API key.
✔️ Monitor usage in Google Cloud Console → APIs & Services → Dashboard.
✔️ Restrict API keys to specific apps or IPs for security.
A Google Cloud project is created inside a Google Cloud account.
A single Gmail account (Google account) can own or manage multiple projects.
You can create multiple projects under the same Gmail, each with its own API keys and quotas.
Each project has its own separate billing, quotas, and API keys (unless they share the same billing account).
Getting Started with Create React App
This project was bootstrapped with Create React App.
npx create-react-app react19-cra
Create a New React App with TypeScript
Run the following command:
npx create-react-app react19-cra --template typescript
What happens here?
• npx ensures you're using the latest Create React App version.
• react19-cra is your project folder name.
• --template typescript sets up TypeScript instead of JavaScript

Publish React component to npm registry as library
npm install --save-dev tsup typescript
Use tools like rollup or tsup to bundle your code.
Option: Use tsup (easier and faster)
Add a tsup.config.ts
Build script in package.json
"build": "tsup"
npm install -D @swc/core
tsup uses SWC (a fast JS/TS compiler) to support ES5
Available Scripts
In the project directory, you can run:
$3
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.
$3
Launches the test runner in the interactive watch mode.\
See the section about running tests for more information.
$3
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.
