Creating Aleo app: React + JS + Leo tutorial

Hello, I am Nina! Welcome to the exciting world of Aleo, where we dive into deploying private applications using React, JavaScript, and the Leo programming language. Aleo empowers developers to create decentralized, privacy-focused apps, ensuring the security of user data in the ever-evolving digital landscape.

Advantages of Aleo app deployment:

1. Privacy-first approach: Aleo places user privacy at the forefront. Its use of zero-knowledge proofs ensures that sensitive info remains private, allowing developers to build apps that prioritize user confidentiality.
2. Decentralization: deploying on Aleo means embracing a decentralized model. Apps run on a network of nodes, reducing the risk of a single point of failure and enhancing overall system resilience.
3. Efficient WASM execution: Aleo leverages WebAssembly for efficient and secure execution of programs. This not only ensures optimal performance but also enhances the overall user experience.
4. Leo programming language: the Leo programming language, designed for writing private applications, simplifies the development process. Its statically typed nature adds an additional layer of security, minimizing the risk of runtime errors.
5. Faucet for seamless testing: Aleo provides a faucet for developers to easily obtain Aleo credits for testing purposes. This feature streamlines the development and testing process, making it hassle-free for developers.

React + JS + Leo tutorial:

1. Installation: begin by setting up the React + Javascript + Leo template. Follow the instructions on the installation page.

This not only installs the necessary modules but also initializes a local React application at http://localhost:5173.

2. Navigation:

• React app: src/App.jsx
• Leo program: helloworld folder

cd aleo-project
npm install
npm run install-leo
npm run dev

3. Execute helloworld.aleo. Visit http://localhost:5173, open the browser console, and hit “execute helloworld.aleo.” You should see a local execution output.

4. Deploying your program:

• Generate an Aleo account: leo account new
• Use the faucet to get Aleo credits:

Using an Aleo Discord faucet:

• Visit https://faucetgreenlist.snarkos.net/ to greenlist your address

• Go to ⁠⛲┃faucet channel in Aleo Discord

• Run a command: /sendcredits your address number of credits
• Example:/sendcredits aleo1abcd 5 to receive 5 Aleo testnet credits to address aleo1abcd

Please make sure to greenlist your address for each new faucet request. 1 request every 24 hours, a maximum of 15 credits per request.

Using SMS:

Also, you have the ability to receive Aleo Credits (available for users in the USA only)

In the opened window, follow the provided instructions. After completing the necessary steps, expect Aleo Credits to be credited to your wallet address within 10 minutes.

5. Deploying your program (contd.)

• Get your transaction ID from Discord.
• Decrypt your credits record: Aleo.tools/rest and Aleo.tools/record.
• Update the fee record in worker.js.
• Hit the deploy button!
