LemonMail DApp is an innovative, decentralized email service focused on security, using a blend of Ethereum contracts and IPFS to ensure that your communication remains private and tamper-proof. This guide will walk you through the steps needed to build and deploy this app while addressing common troubleshooting issues. Let’s dive in!

Step-by-Step Guide: Building the Application

To get started, you’ll want to follow these simple commands to build the LemonMail DApp:

• Open your terminal.
• Run the command to install necessary dependencies: npm install
• Prepare the application for production: npm run production
• Copy the built files for IPFS deployment: cp -r public/web/dist* public/Ipfs

Publishing the Application on IPFS

Once you’ve built the application, you’ll want to publish it on IPFS for others to access it easily. To do this, run the following command:

ipfs add -r public/Ipfs

If successful, you’ll receive a hash as confirmation, such as QmfJ856Hu6LCHo64eMrvnKPpqevAkB8aJ83o1cMrtt59KM. You can access your app using an IPFS gateway like https://ipfs.io/ipfs/QmfJ856Hu6LCHo64eMrvnKPpqevAkB8aJ83o1cMrtt59KM.

Understanding the Code: An Analogy

Think of the LemonMail DApp as a secure letter delivery service that doesn’t rely on a post office. Instead, it uses a network of private couriers (Ethereum and IPFS) to transport messages directly to the recipient without any risk of interception. Each courier uses a unique lock (public key encryption) that only the intended recipient has the key for, making it impossible for anyone else to access or tamper with the letters (messages). Just like you’d send a parcel without any oversight from a postal service, LemonMail ensures your messages are off-limits to even the developers!

Troubleshooting Tips

If you encounter any issues during the build or deployment process, consider the following troubleshooting ideas:

• Error During npm Installation: Make sure Node.js and npm are updated to their latest versions.
• IPFS Not Responding: Ensure that your IPFS daemon is running properly before trying to publish your files.
• Missing Kovan Ether: If you need Kovan Ether to test the DApp, contact the developers—we’re more than happy to assist you!
