Full Stack dApp Tutorial Series - Intro

Intro In this series, well build a simple dApp (decentralised application).   Well introduce all the different pieces of the tech stack and tools you can use to build a dApp.   The dApp will simply allow any user to issue a bounty in ETH Any user with an Ethereum account can Issue a bounty in ETH with the requirements Any user can submit a fulfillment of the bounty with evidence The bounty issuer can accept a fulfilment which would result in the fulfiller being paid out Prerequisites Youre a sof

Tools for dApp development

This article will introduce you to the relevant tools required for developing a simple dApp. We will introduce tools in the following areas: Smart Contract Programming Languages Web3 Libraries Development frameworks IDEs Development blockchains Ethereum Networks Wallets (Key Stores) SaaS / Cloud Infra Data Storage Smart Contract Programming Languages Because a smart contract is deployed on the blockchain in its bytecode form, any language that comes with an EVM compiler could be used to write a

Solidity - Your First Smart Contract

Solidity Basics

Tools for Working With Solidity

Recently a group of Blockchain enthusiasts at the co-working space I occasionally work from decided that it was time we stopped talking about Blockchain and actually learned how to create something based on it. We wanted to create a coin or token for the community to use internally, and whilst the project has stalled for now, I started investigating Ethereum in more depth, and the language it uses for creating smart contracts, Solidity . I will cover the language itself in more detail in the fut

Remix IDE - Your first smart contract

The easiest place to start writing smart contracts in Solidity in with the online Remix IDE. As its an online IDE, no installation or development environment setup is required, you can navigate to the site and get started! Remix also provides good tools for debugging, static analysis, and deployment all within the online environment. You can find the source code used in this tutorial in this GitHub repository. Before we get started, a quick reminder of what we are building: A dApp which allows a

Understanding smart contract compilation and deployment

As discussed earlier in the series, when developing dApps, and especially writing smart contracts, there are many repetitive tasks you will undertake. Such as compiling source code, generating ABIs, testing, and deployment. Development frameworks hide the complexity of these tasks and enable you as a developer to focus on developing your dApp/idea. Before we take a look at these frameworks such as truffle, embark and populous, we’re going to take a detour and have a look at the tasks performed a

Building With Truffle

Compiling, Testing, & Adding A Frontend With The Truffle Framework

Truffle: Smart Contract Compilation & Deployment

Intro Earlier in the series, we took a look at how to manually deploy and interact with our Bounties.sol smart contract on a local development blockchain. We also briefly touched on development frameworks which hide the complexity of these repetitive tasks and allow us to focus on developing dApps. This article will walk through the steps required to setup Truffle and use it to compile, deploy and interact with our Bounties.sol smart contract. You should see that this is a much easier process th

Truffle: Testing your smart contract

Earlier in the series, we took a look at how to setup Truffle and use it to compile, deploy and interact with our Bounties.sol smart contract. This article will walk through the steps required to write tests for our smart contract within the Truffle framework. Tests in Truffle projects can be written in Javascript or Solidity, however, this article will focus on the Javascript tests. Truffle uses the Mocha testing framework to provide an easy way to write tests in Javascript and uses Chai for as

Truffle: Adding a frontend with react box

Earlier in the series, we took a look at how to setup Truffle and use it to compile, deploy and interact with our Bounties.sol smart contract. This article will walk through the steps required to add a simple react.js front end to our Bounties dApp so that users can interact with our smart contract using their web browser. Source code for this tutorial can be found here. Truffle Box Truffle boxes are helpful boilerplate code, pre-configured to help you get up and running quickly developing your

Building With Populus

Compiling, & Testing With The Populus Framework

Populus: Smart contract compilation and deployment

Populus: Smart contract compilation and deployment Note: this guide outlines Populus as it stands right now and is a work in progress. As this guide was being written, support for Web3.py 4 has been introduced, and eth-tester support was added while ethtestrpc was removed (as of PR#474). Shortly after this, Piper Merriam (via ethereum/populus gitter) indicated that a new tool, called pytest-ethereum, is being prototyped and it is intended to be “a standalone replacement for alot of what populus

Populus: Testing your smart contract

Populus, the tester chain, and web3.py: Testing your smart contract This article breaks from the other DappSeries articles, and instead incorporates a set of Python tooling for your smart contract testing needs. A note on pending refactors to the Populus tool (a truncated list, per Piper Merriam): Change populus to use eth-tester for testing (currently using eth-testrpc) Remove need for project.json in project directory Removal of the Chain API entirely Removal of the scripts that setup local te

Deploying Your dApp

Deploying your application to the cloud

Deploying a full-stack dapp to Microsoft Azure

In the previous tutorials in this series we saw how to develop a full-stack blockchain dapp. In this tutorial, we learn how to deploy a dapp using Microsoft Workbench Blockchain. Deploy Blockchain Workbench Blockchain Workbench allows you to deploy a blockchain ledger along with a set of Azure services used to build a dapp. Once deployed, Blockchain Workbench provides access to client apps to create and manage users and blockchain applications. The following steps highlight on how to deploy bloc

Deploying Your dApp Frontend to Heroku

Deploying Your App to Heroku Earlier in the series, we deployed our Bounties.sol smart contract using Truffle, and added a react.js front end to interact with the contract through a web browser. In this tutorial we deploy our front-end application to Heroku. This tutorial uses the source code from the tutorial, Truffle: Adding a frontend with react box. You have to add a Procfile to the project, but no other changes are required. Heroku Heroku is a Platform-as-a-Service (PaaS) that enables devel

Deploying a full-stack dApp to Amazon EC2

Deploying a full-stack dApp to Amazon Elastic Cloud Computing (AWS-EC2) In the previous tutorials in this series, we saw how to develop a full-stack ethereum-based blockchain dApp. In this tutorial, we learn how to deploy the dApp to an Amazon web services (AWS) elastic cloud computing (EC2) instance. We also create a private ethereum blockchain node using kaleido and configure the dApp to work with this blockchain node. Prerequisites To complete this tutorial, you need a good understanding of t

Deploying a full-stack dApp to Google Cloud

In the previous tutorials in this series, we saw how to develop a full-stack ethereum-based blockchain dApp. In this tutorial, we learn how to deploy the dApp to two of Googles Cloud offerings, Firebase, and Cloud storage. Google Cloud is a suite of products similar to Amazons AWS, ranging from computation and databases to storage. Google Firebase is an abstraction and subset of Google Cloud, making it easier for developers to use Google Cloud infrastructure. For example, Firebase Functions is a
