If you want to test your project locally, you can use the following commands:
# Starts the replica, running in the background
dfx start --background
# Deploys your canisters to the replica and generates your candid interface
dfx deploy
Once the job completes, your application will be available at http://localhost:4943?canisterId={asset_canister_id}
.
Additionally, if you are making frontend changes, you can start a development server with
npm start
Which will start a server at http://localhost:8080
, proxying API requests to the replica at port 4943.
