Step 5: Start the Development Server and Verify Setup
After configuring your project with necessary dependencies and adjusting the Webpack configuration for browser compatibility, the next step is to start your React app's development server. This will allow you to verify that your setup is correct and that your application is ready for development and interaction with the Eclipse Devnet.
Starting the Development Server
Open Your Project's Terminal:
Navigate to the terminal within Visual Studio Code or your preferred terminal application. Ensure you're in the root directory of your
nftminterfrontend
project.
Run the Development Server:
Execute the following command to start the development server:
Alternatively, if you have configured your project to use
react-app-rewired
for overriding the Webpack configuration without ejecting fromcreate-react-app
, make sure to run:This command compiles your application and serves it locally, usually opening your default web browser to
http://localhost:3000/
automatically, where you can view your running application.
Verifying Your Setup
Check Browser Console: Once your app is running in the browser, open the developer console (usually accessible with F12 or right-click > "Inspect" > "Console" tab). Look for any errors that might indicate issues with the Webpack configuration, missing dependencies, or other setup problems.
Test Blockchain Connectivity: If your app includes initial code to establish a connection to the Eclipse blockchain or interact with it, verify that these functionalities are working as expected. For example, you might have code to connect to the Eclipse blockchain's devnet and fetch the balance of a wallet address; ensure this executes without errors.
UI Rendering: Ensure that your application's UI renders correctly and that any React components related to Solana interactions (e.g., wallet connection buttons) are visible and functioning.
Troubleshooting
Module Not Found Errors: If you encounter errors related to missing modules or packages, double-check your
package.json
to ensure all necessary dependencies are listed and correctly installed withnpm install
.Blockchain Connection Issues: Ensure you're pointing to the correct RPC URL for the Eclipse blockchain's devnet and that your Solana wallet adapter setup is correctly configured for wallet connections.
Webpack Configuration Errors: If you run into issues related to the Webpack configuration, review your
webpack.config.js
file or the configuration overrides viareact-app-rewired
to ensure they match the instructions provided.
Next Steps
With your development server running and setup verified, you're ready to proceed with building out the front-end of your NFT minter application. This includes creating UI components for interacting with your smart contract, such as minting NFTs, and integrating wallet functionality for transactions on the Eclipse devnet.
Consider implementing features step-by-step, continually testing and verifying functionality through the development server to ensure a smooth development process.
Starting the development server and verifying your setup confirms that your project environment is correctly configured for developing a blockchain-enabled React application, setting the stage for further development and blockchain integration.
