vitorbal / routeChangeSaga.js
Created February 7, 2017 12:09
A Saga that allows you to describe route changes using the `meta.redirect` property of your action objects. FSA-compliant.
// A saga that looks for a route change request in every action. Example usage:
// export const selectConversation = ({ id }) => ({
// type: SELECT_CONVERSATION,
// payload: {
// conversationId: id,
// },
// meta: {
// redirect: {
// url: `inbox/${id}`, // <-- the saga will redirect to this url
// replace: true, // <-- if the route should be replaced or pushed on top of the history stack

Best practices for writing PropTypes for React Components (Work in Progress)

Best Practices for React PropTypes

  • Avoid using PropTypes.string for a prop that sets a type/variation, use PropTypes.oneOf(CONSTANT) instead:

Button.propTypes = {
    size: React.PropTypes.string
};

// Good:

jscodeshift transform to add metadata to all ESLint rules

jscodeshift transform to add metadata to all ESLint rules

This transform was created to programmatically add metadata to all ESLint rules (#5417).

here's a live example for the no-trailing-spaces rule.

Please note:

  • The rule mappings were initially created by scraping eslint.org/docs/rules using jsdom.
  • The scraping assumes all fixable rules are of fixable type whitespace. This is not true for 4 rules, which were fixed manually afterwards:
    • semi
  • no-extra-semi
