Now that we've got you all excited, let's go through what you need to get started building with Aragon 😊
Note before starting: Windows is not officially supported by aragonCLI at the moment.
First off, we need to be sure we have the right version of Node.js installed to prevent errors.
To see which version of Node you have installed, from the command line run:
Next, we'll need what we call a web3 provider to actually sign and send transactions to the Ethereum (or another) blockchain.
For now in this section, to interact with the Aragon app we'll be using Metamask. If you haven't please proceed with the installation of Metamask.
Now install aragonCLI from the command line running:
npm i -g @aragon/cli
Again: It is recommended to have NVM installed so that you can switch to
Node v12.7 LTSto install the cli. At the moment the product isn't compatible with the later versions of node anymore.
If the installation takes a long time don't worry. It can happen, wait until the process is completed (sometimes it takes 30 min!).
aragon -vwhether the package has indeed installed.
If you're having trouble with this step, you should take a look at the installing aragonCLI section of the troubleshooting guide. If that doesn't fix things, please don't hesitate to reach out to us in the #dev-space channel off our Discord server.
The Aragon Builder plugin is a user-friendly tool for developing apps on top of Aragon. The plugin is automatically installed when using the boilerplate templates but we can suggest to install now with the following command:
npm i @aragon/buidler-aragon
In order to get up and running quickly, we’ll build our first DAO using some basic scaffolding. Just like real scaffolding in a construction site, when we talk about scaffolding in this context, we mean a simple prebuilt structure for your project, on top of which you can build the real one.
To create your first (scaffolded) DAO, from the command line run:
npx create-aragon-app first-dao.aragonpm.eth
Don't worry about fully understanding this line right now. Really. We'll cover that in the tutorial coming up. Right now, you just need to know that the scaffolding relies on some generated code, magically created by the
If you're unsure what the difference is between
npm, we recommend you read through this medium post and this stackoverflow post.
Now if you look at your terminal, you should see a five step process:
Cloning app template
Installing package dependencies
Created new application first-dao.aragonpm.eth in first-dao.
Once all 5 have ticks next to them, you should run the following:
cd first-dao, just moves us into the directory where the scaffolded app was created.
yarn start, sets up everything for us in the background so we can quickly live test our DAO.
If you've made it this far congrats 🤗. You've just created your first DAO! It’s running on your local network and as soon as it's ready it will open in your browser at localhost:3000!
Once your browser is open at the right address, you should see a screen that looks like the one below.
As you can see on the left, this DAO is made up of two Aragon apps:
- first-dao (Counter)
Right now, we're in the Home app. This app just displays a welcome message with no possible user interactions.
Click on first-dao to open up the (slightly) more interesting Counter app.
Right now the count is at 0. Let's increment it.
Note that incrementing the counter triggers a blockchain transaction that saves the new value to the chain. But before the transaction can be sent, we need to sign it (to prove it was us that really sent it).
Click on the + button, which opens a Metamask transaction and sign it. For help on how to sign a transaction on Metamask go through these steps:
After the transaction is completed, you should see Count: 1.
Done! We hope you enjoyed that 😊!
Now that you’ve built your first DAO, feel free to take a look at the docs. If you're interested in understanding things at a deeper level go ahead to this tutorial!
