TypeScript boa-core O Examples

Example #1

File: handler.ts Project: bouzuya/b-o-a

 const handler = (action$: O<A<any>>, options: any): O<A<any>> => {
   const is = (action: A<any>): boolean => action.type === typeT;
   const other$: O<A<any>> = action$
     .filter(action => !is(action));
   const target$: O<A<T>> = action$
     .filter(is);
   const result$: O<A<U>> = dispatch(target$)
     .filter(a => !!a)
     .share();
   return O.merge(result$, other$);
 };

Example #2

File: init.ts Project: bouzuya/rally-rxjs

 return (action$: O<A<any>>, _: any): O<A<any>> => {
   return O.merge(
     action$,
     action$.first().map(() => {
       runServer(serverOptions, expressHandler);
       return; // return undefined
     })
   )
     .filter(a => !!a) // remove undefined
     .share();
 };

Example #3

File: handler.ts Project: bouzuya/b-o-a

const init = (options: XXXOptions): XXXResponse => {
  const { fs, tActionType, uActionType } = options;
  const typeT = tActionType ? tActionType : tActionTypeDefault;
  const typeU = uActionType ? uActionType : uActionTypeDefault;

  const dispatch = (action$: O<A<T>>): O<A<U>> => {
    return action$
      .map(({ data }) => fs[data.name](data.params))
      .map(data => ({ type: typeU, data }));
  };

  const handler = (action$: O<A<any>>, options: any): O<A<any>> => {
    const is = (action: A<any>): boolean => action.type === typeT;
    const other$: O<A<any>> = action$
      .filter(action => !is(action));
    const target$: O<A<T>> = action$
      .filter(is);
    const result$: O<A<U>> = dispatch(target$)
      .filter(a => !!a)
      .share();
    return O.merge(result$, other$);
  };

  return { handler };
};
