@react-ddd/eslint-config

This package is a draconian eslint-config largely based on airbnb and airbnb-typescript. It does NOT use Prettier, instead relying on only one tool to handle code formatting.

Differences from airbnb and airbnb-typescript

react/function-component-definition

Use arrow functions for all components

react/jsx-props-no-spreading

Disable

react/require-default-props

Disable, as we use TypeScript and type the props

@typescript-eslint/comma-dangle

Only in .tsx files Ignore for generics, so that you can have a single unconstrained generic for components:

const GenericComponent<T,> = (...) => {}

@typescript-eslint/brace-style

Disable ignoring single line. ALL braces are required, no single line if's!

@typescript-eslint/consistent-type-imports

Force TypeScript 3.8 style type imports for all types

@typescript-eslint/no-unused-expressions

Error, except for short circuit and ternary

Testing specific rules

There are specific rules for *.spec.tsx? files to accomodate jest-gwt style testing:

    'error',
    {
      code: 100,
      ignoreUrls: true,
      ignoreRegExpLiterals: true,
      ignorePattern,
    },
  ],
