eslint-config

Breaking: Drop official support for Node.js version 12

Breaking: Enable rule @typescript-eslint/explicit-member-accessibility.

Breaking: Enable rule @typescript-eslint/no-use-before-define for classes, variables, enums, and typedefs but not for functions which are safely hoisted and type references which are also effectively hoisted.

Feature: Set env.es2021 to true

Feature: Commit the result of eslint --print-config for each .eslintrc file.

Breaking: Enable @typescript-eslint/no-shadow and disable the associated base rule to work around a bug where all enums are reported as shadowing https://stackoverflow.com/a/63961972/2793540.

Split out separate node.eslintrc.json and react.eslintrc.json configurations to avoid spurious errors when using with Node.js. Keep the main .eslintrc.json as a combination of the two.

• Potentially breaking: Upgrade dependencies. Require TypeScript >=4.0.

• Breaking: Enable rule @typescript-eslint/no-explicit-any. Use unknown instead.

• Feature: Disable no-useless-constructor which incorrectly identifies things like:

class Foo {
   constructor(public readonly bar: string) {}
}

• Breaking: Enable explicit-module-boundary-types https://github.com/typescript-eslint/typescript-eslint/blob/main/packages/eslint-plugin/docs/rules/explicit-module-boundary-types.md . Previously this was a warning. Now it's an error.
