Incubed React Truffle Box

This box comes with everything you need to start using Incubed Client (IN3) from a react app. This is as barebones as it gets, so nothing stands in your way.

Installation

First ensure you are in a new and empty directory.

1. Run the unbox command via npx and skip to step 3. This will install all necessary dependencies. A Create-React-App is generated in the client directory.

   npx truffle unbox in3-react

2. Alternatively, you can install Truffle globally and run the unbox command.

   npm install -g truffle
   truffle unbox in3-react

3. For simplification, this truffle box initially does not have any Smart Contract. Because, in most cases, an IoT device will just read something from the Blockchain. So you can skip this step and the one after and go directly to step 5, except if you added later some Smart Contracts to your project.

   Run the development console.

   truffle develop

4. Compile and migrate the smart contracts. Note inside the development console we don't preface commands with truffle.

   compile
   migrate

5. In the client directory, we run the React app.

   // in another terminal (i.e. not in the truffle develop prompt)
   cd client
   npm run start

6. Truffle can run tests written in Solidity or JavaScript against your smart contracts. Note the command varies slightly if you're in or outside of the development console.

   // inside the development console.
   test
   
   // outside the development console..
   truffle test

7. Jest is included for testing React components.

   // ensure you are inside the client directory when running this
   // If you added some contracts, compile them before running Jest, or you may receive some file not found errors.
   npm run test

8. To build the application for production, use the build script. A production build will be in the client/build folder.

   // ensure you are inside the client directory when running this
   npm run build

FAQ

• How do I use this with the Ganache-CLI?

  It's as easy as modifying the config file! Check out our documentation on adding network configurations. Depending on the port you're using, you'll also need to update line 29 of client/src/utils/getWeb3.js.

• Where is my production build?

  The production build will be in the client/build folder after running npm run build in the client folder.

• Where can I find more documentation?

  This box is a marriage of Truffle, Incubed Client IN3 and a React setup created with create-react-app. Either one would be a great place to start!
