Readme
This module helps to initialize an ethers provider based on environment variables.
Install
npm i ethers-provider-init --save
Usage
Depending of the environment variables the provider might use:
- the default provider
ethers.provider.getDefaultProvider()
if no provider is configured - one of the currently available providers
- the fallback provider if more than one provider is configured.
const { getProvider } = require("ethers-provider-init");
const provider = getProvider();
// alternatively you can pass an object with the environment variables:
// const provider = getProvider({ CLOUDFLARE_ENABLED: "1" });
