react-code-blocks/src/hooks/use-warning.ts

Modified Atlaskit's Code Block to support more languages (i.e graphql, reasonml, etc) and theme (i.e railscast, dracula, monokai, etc) code snippets!

const warningStack: { [key: string]: boolean } = {};

const useWarning = (message: string, component?: string) => {
  const tag = component ? ` [${component}]` : ' ';
  const log = `[Zeit UI]${tag}: ${message}`;

  if (typeof console === 'undefined') return;
  if (warningStack[log]) return;
  warningStack[log] = true;

  if (process.env.NODE_ENV !== 'production') {
    return console.error(log);
  }

  console.warn(log);
};

export default useWarning;
