I'm working with a framework ('hardhat') that automatically requires a package ('ethers') but eslint keeps calling it out as undefined. Requiring 'ethers' is not a solution because it just breaks everything; but from what I understand, a way to add exceptions to the entire document is to place overrides in a comment block above the entire thing.
/*
eslint-disable jest/valid-expect
*/
const { expect } = require("chai");
const { txHist } = require("../scripts/utils.js");
describe("DStor", () => {
let DStor;
let deployer, user1, user2, user3, users; // eslint-disable-line no-unused-vars
beforeEach(async () => {
// Get ContractFactory and Signers
const DStorFactory = await ethers.getContractFactory("DStor"); // 'ethers' is highlighted with no-undef
...
I suspect the solution is to add another eslint-disable rule, but I don't know how to target the 'ethers' package with it. Anyone have any solutions?
Update: fixed by adding const { ethers } = require("hardhat");
Have a look at ESLint globals. Basically, you can declare a global value ethers in your ESLint configuration, and that will be treated as defined in all linted files.
For ESLint >= 7, if your configuration file is .eslintrc, add an entry like:
{
"globals": {
"ethers": "readonly"
}
}
For ESLint < 7, use "ethers": false instead.
