Welcome to the world of decentralized applications! In this blog post, we will walk through the process of setting up an Angular-Truffle starter app, which allows you to write, compile, and deploy smart contracts on the Ethereum blockchain using Angular 4. Ready to dive in? Let’s get started!
Project Overview
This project is an Angular 4 application integrated with Truffle, a development environment for Ethereum. With this setup, you can interact with the Ethereum blockchain seamlessly. The project was created using Angular CLI, version 1.0.0.
Demo
Create a coin with an initial supply and send an amount to your Ethereum wallet address. Here’s a glimpse of what you’ll accomplish:
How to Use This Project
There are two main parts to get this project running smoothly. Let’s break it down:
Part 1: Setting Up the Project
- Clone the repository:
git clone https://github.com/Nikhil22/angular-truffle-starter-dapp.git
- Navigate to the project directory:
cd angular-truffle-starter-dapp
- Install dependencies:
npm install
Part 2: Running the Application
Make sure you have Angular CLI installed. For that, use:
npm install -g @angular/cli
If you’re new, install ganache-cli to run a local blockchain RPC server:
npm install -g ganache-cli
Now, run ganache-cli in a new terminal tab. You will also need to connect to an Ethereum client. A great tool for this is MetaMask. Be sure to set your MetaMask network to Localhost 8545 to avoid browser errors.
Executing Your Application
In your original terminal tab, run the following commands:
- Compile your contracts:
truffle compile
- Deploy contracts:
truffle migrate
- Serve the application:
ng serve
Now navigate to http://localhost:4200. The app will reload automatically if you make any changes.
Code Scaffolding and Building Your Project
You can create new components with:
ng generate component component-name
For building the project, use:
ng build
This will store the artifacts in the dist
directory. To prepare for production, use the -prod
flag.
Testing Your Application
To run unit tests, use:
ng test
For smart contract tests, use:
truffle test
End-to-end tests can be run with:
ng e2e
Before these tests, ensure the application is being served using ng serve
.
Troubleshooting Tips
- Make sure that your MetaMask is set to the right network, or you’ll encounter errors.
- If you face compilation issues, ensure all dependencies are correctly installed.
- Check the browser console for any errors to identify where things may have gone wrong.
