What you'll learn:
[Description] Learn how to interact with the Ethereum blockchain from your front-end using Web3.js. This includes connecting to a provider, interacting with smart contracts, and reading data from the blockchain. - **Resources/Activities:** - Read the Web3.js documentation. - Create a simple dApp that retrieves the current block number from the blockchain. - Learn to connect to a local development network (Ganache) or a testnet (e.g., Goerli). - **Expected Outcomes:** - Understanding of how to use Web3.js to interact with the blockchain. - Ability to connect to a blockchain node and read data. - A simple dApp that displays blockchain data.
Personal Notes:
What you'll learn:
[Description] Learn how to interact with smart contracts deployed on the blockchain from your front-end. This involves calling contract functions, sending transactions, and handling events. - **Resources/Activities:** - Deploy a simple smart contract (e.g., a "Hello World" contract or a simple counter contract) to a testnet. - Write front-end code to interact with the deployed contract (e.g., call functions, send transactions). - Learn to handle contract events. - **Expected Outcomes:** - Ability to interact with deployed smart contracts from the front-end. - Understanding of how to call contract functions and send transactions. - Understanding of how to handle events emitted by smart contracts.
Personal Notes:
What you'll learn:
[Description] Use a front-end framework like React (most common), Vue.js, or Angular to build a basic user interface for your dApp. This improves structure and ease of development. - **Resources/Activities:** - Choose a framework (React is recommended for its popularity and ecosystem). - Follow a beginner-friendly tutorial for the chosen framework. - Create a UI for your existing dApp, allowing users to interact with your smart contract via the UI. - **Expected Outcomes:** - Basic understanding of your chosen front-end framework. - A functional UI for interacting with your smart contract. - Improved code organization and front-end development skills.
Personal Notes:
What you'll learn:
[Description] Learn basic testing practices for your dApp and consider security best practices. Explore potential next steps in your Web3 journey. - **Resources/Activities:** - Learn basic unit testing using tools like Mocha or Jest. - Research common security vulnerabilities in dApps (e.g., reentrancy attacks, front-running). - Explore advanced topics like decentralized storage (IPFS), different wallets, advanced dapp structures, or learn Solidity to build your own Smart Contracts. - **Expected Outcomes:** - Understanding of basic testing principles. - Awareness of common dApp security risks. - Knowledge of further learning paths.
