A simple app to illustrate basic features of the Flow Client Library (FCL). These include:
- User authentication and authorization
- Querying and mutating the Flow Blockchain
- User signing of messages (with onchain verification)
This project was bootstrapped with Create React App.
FCL has a mechanism that lets you configure various aspects of FCL.
./config.js
contains basic configuration information for FCL, such as what Access Node and wallet discovery endpoint to use (e.g. testnet or a local emulator).Configuration is
imported in ./root.js
(it's recommended you do as early in the life cycle as possible), and made available via the useConfig
hook.
- accessNode.api -- Api URL for the Flow Blockchain Access Node you want to be communicating with.
- discovery.wallet -- Points FCL at the Wallet or Wallet Discovery mechanism.
📣 Tip: It's recommend to replace these values with environment variables for easy deployments across different environments like development/production or Testnet/Mainnet.

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.
