Dev3 Chainlink SDK

Dev3 Chainlink SDK is a fully open source Typescript SDK which enables any frontend developer to fetch the prices of various assets through Chainlink DataFeeds. Users can fetch price pairs, NFT floor price information & more...

Getting started

Install the SDK by typing in your npm project (Angular, React, vanilla npm, ...)

npm install dev3-chainlink-feeds

In your JavaScript or TypeScript file import the SDK with:

import { Dev3ChainlinkSDK } from 'dev3-chainlink-feeds'

Then import all the Price Feeds you want:

import { PriceFeedsETH } from 'dev3-chainlink-feeds'
import { PriceFeedsAVAX } from 'dev3-chainlink-feeds'
import { PriceFeedsBSC } from 'dev3-chainlink-feeds'

Initialize the SDK by calling:

const ethSDK = new Dev3ChainlinkSDK('https://rpc-node-url.xx', new PriceFeedsETH())
const avaxSDK = new Dev3ChainlinkSDK('https://avax-rpc-url.xx', new PriceFeedsAVAX())

And simply fetch a price pair by calling the price feeds functionality on the SDK:

ethSDK.getFromOracle(ethSDK.feeds.AAVE_ETH).then(res => { console.log(res) })

Modern development

Dev3 Chainlink SDK extracts all the pair contracts addresses for all networks that are compatible into code generated classes, so all modern editors will support full code autocomplete.

Reading data

The data is returned in the form of an RoundDataModel object:

export interface RoundDataModel {
    roundID: BigNumber;
    answer: BigNumber;
    formattedAnswer?: string;
    startedAt: BigNumber;
    updatedAt: BigNumber;
    answeredInRound: BigNumber;
    assetName?: string;
    dataFeedName?: string;
}
