Chainlink Starter

A starter project for deploying a chainlink node and making requests to it

This project is inspired by airnode-starter and aims to help people who are new to chainlink to get some first hand experience. It is a demo for "Running a Chainlink Node" from the official chainlink doc. I have fun setting it up and it helps me better understand how the system works. I hope it will be the same for you!

Setup

On local testnet

1. Clone this repo
2. Install docker
3. Run the following script

# in the project root folder
./local-setup.sh

If everyhing goes well, you can visit http://localhost:6688 and enter the default credential to login. The credential is

account: user@test.com
password: password

(The credential is stored in credential/.api)

You will see an example job added in the job page.

On Rinkeby testnet

Before proceeding, make sure you follow the instructions and successfully setup the chianlink infrastructure on aws.

1. Clone this repo
2. Install docker
3. Replace the endpoint in /env/.env.linknode with your own
4. Go to Infura, create an account and get Rinkeby provider URL(one for https, one for websocket)
5. Create/Replace both URL in your /env/.env.provider file with the URL you got from Infura

# it should look something like this
PROVIDER_HTTP_URL=https://rinkeby.infura.io/v3/{YOUR_KEY}
PROVIDER_WS_URL=wss://rinkeby.infura.io/ws/v3/{YOUR_KEY}

6. Run the following script

# in the project root folder
./rinkeby-cloud-setup.sh

Note: The script will ask you to fund the generated wallet, you can get some free ethers from https://faucet.rinkeby.io

Make request

On local testnet

# in the project root folder
docker run --env NODE_ENV='local' --net=host -v $(pwd):/chainlink-dev/ -it chainlink-local-dev \
node scripts/make-request.js

On Rinkeby testnet

# in the project root folder
docker run --env NODE_ENV='rinkeby' --net=host -v $(pwd):/chainlink-dev/ -it chainlink-local-dev \
node scripts/make-request.js
