An excercise in connecting NEAR blockchain and Arweave storage.
To run this project locally:
- Prerequisites: Make sure you've installed [Node.js] ≥ 12
- Install dependencies:
yarn install
- Run the local development server:
yarn dev
(seepackage.json
for a full list ofscripts
you can run withyarn
)
Now you'll have a local development environment backed by the NEAR TestNet!
Go ahead and play with the app and the code. As you make code changes, the app will automatically reload.
Every smart contract in NEAR has its [own associated account][NEAR accounts]. When you run yarn dev
, your smart contract gets deployed to the live NEAR TestNet with a throwaway account. When you're ready to make it permanent, here's how.
[near-cli] is a command line interface (CLI) for interacting with the NEAR blockchain. It was installed to the local node_modules
folder when you ran yarn install
, but for best ergonomics you may want to install it globally:
yarn install --global near-cli
Or, if you'd rather use the locally-installed version, you can prefix all near
commands with npx
Ensure that it's installed with near --version
(or npx near --version
)
Each account on NEAR can have at most one contract deployed to it. If you've already created an account such as your-name.testnet
, you can deploy your contract to arweave_tutorial.your-name.testnet
. Assuming you've already created an account on [NEAR Wallet], here's how to create arweave_tutorial.your-name.testnet
:
-
Authorize NEAR CLI, following the commands it gives you:
near login
-
Create a subaccount (replace
YOUR-NAME
below with your actual account name):near create-account arweave_tutorial.YOUR-NAME.testnet --masterAccount YOUR-NAME.testnet
Modify the line in src/config.js
that sets the account name of the contract. Set it to the account id you used above.
const CONTRACT_NAME = process.env.CONTRACT_NAME || 'arweave_tutorial.YOUR-NAME.testnet'
One command:
yarn deploy
As you can see in package.json
, this does two things:
- builds & deploys smart contract to NEAR TestNet
- builds & deploys frontend code to GitHub using [gh-pages]. This will only work if the project already has a repository set up on GitHub. Feel free to modify the
deploy
script inpackage.json
to deploy elsewhere.
