pathway

01. Connect to a Acala node

Our aim, is to connect to a Acala node using and RPC provider. We will build a set of simple Node applications. Hopefully this will become clear(er) as we continue on this pathway. Acala has built a library for us to easily interface, build, and connect.

We will need Node.js and based on your OS, install the appropriate distribution.

node -v
v14.16.1

Create a project folder, change directory, and initialise as such:

mkdir acala
cd acala
npm init -y

Upon completion of the above commands you'll find a package.json with the following entries:

{
  "name": "acala",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
  "license": "ISC"
}

Install packages dotenv, axios, polkadot, acala

npm install --save dotenv axios @polkadot/api @acala-network/api@beta

Upon completion of the above commands you'll find a package.json with the following entries:

{
  "name": "acala",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
