ICP Development Environment with Azle and React

This template gives you everything you need to build a full-stack Web3 application on the Internet Computer. It includes a frontend built with Vite and React, and a backend written in JS/TS (Azle).

Get started with one click:

Locally:

Make sure you have you have the latest version of Docker (e.g. >25) and VS Code installed and running, then click the button below

In your browser:

In Gitpod

or GitHub Codespaces

🚀 Develop

When the editor opened, run the following commands to start a local ICP node and deploy the canister smart contract:

dfx start --clean # Start a local ICP node
# In a new terminal window:
dfx deploy # Deploy smart contract locally

The smart contract will be reachable under http://bkyz2-fmaaa-aaaaa-qaaaq-cai.localhost:4943. Call the smart contract using curl on the command line:

# contacts endpoint
curl http://bkyz2-fmaaa-aaaaa-qaaaq-cai.localhost:4943/contacts
# price-oracle endpoint
curl -X POST http://bkyz2-fmaaa-aaaaa-qaaaq-cai.localhost:4943/price-oracle -H 'content-type: application/json' -d '{"pair": "ICP-USD"}'

You can also use tools like Postman or HTTPie to interact with the smart contract. To redeploy the smart contract, run dfx deploy again.

When ready, run dfx deploy --ic to deploy your application to the ICP mainnet. The command will print a different canister URL for mainnet, ending in .raw.icp0.io. You can make calls to the smart contract on mainnet just like to the local one!

💡 Tips and Tricks

When developing remotely, navigating to the canister's frontend in the browser will not work. Use curl on the command line instead, or develop locally.
Note that you might need to disable CORS in your browser to make backend calls from localhost. For example, for Chrome, run open -n -a /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --args --user-data-dir="/tmp/chrome_dev_test" --disable-web-security to disable CORS.
If you get an error "Error: An error happened during communication with the replica: ... Connection refused", run dfx start --clean to start dfx.
