Style Choices

This guide extends Airbnb's JS style with a few opinionated tweaks to make your life easier.

• arrow-parens has been loosened so simple expressions don't require parentheses
• comma-dangle is disabled
• import/no-extraneous-dependencies is disabled, this can stop you importing devDeps and types, etc
• import/no-unresolved is disabled, this should be a build time error, not a linting issue
• max-len has been bumped up to 140 characters. You could put a tweet on every line!
• no-plusplus has been disabled. Only needed to avoid insane edge cases.
• prefer-template is disabled

React

• react/jsx-filename-extension is disabled
• react/jsx-props-no-spreading is disabled, sometimes this is required
• react/require-default-props is disabled, sometimes undefined is fine
• react/jsx-one-expression-per-line is disabled. Makes "Hello {name}" invalid, come on.
• react/static-property-placement is disabled with typescript
• jsx-a11y/accessible-emoji is disabled, because come on, no one can be bothered

Typescript

• consistent-return disabled, this should be enforced by the typescript compiler
• spaced-comment modified to allow /// comments
