Usage of linters/linting tools within Deno

Question

I am currently exploring Deno as proof-of-concept, and I am trying to find suitable way to setup linting within the project.

Here is part of the eslint configuration that I am thinking of setting up, but I do understand that this can cause more problems due to the differences between Node.JS and Deno:

parser: '@typescript-eslint/parser',
extends: [
  'eslint:recommended',
  'plugin:@typescript-eslint/eslint-recommended',
  'plugin:@typescript-eslint/recommended',
],

That being said, what are some of practices/methods to set up linting and formatting within Deno/ TypeScript projects?

I understand that deno lint is still a work in progress, and the lack of documentation is hindering me from adopting it at this moment.

Answer 1

This is the eslint config Deno uses, and works perfectly for std/ which uses Deno.
