promesify 0.0.2 • Public • Published 10 years ago Suppose you have some asynchronous callback-based API, which you want to use but you like promises. This is where promesify becomes handy. So lets say you have some API object
myApi = new SuperDuperApi ( ) ;
Now instead of doing this:
myApi . method1 ( function ( err ) {
if ( err ) return ;
myApi . method2 ( function ( err ) {
if ( err ) return ;
myApi . method3 ( function ( err ) {
} ) ;
} ) ;
} ) ;
thanks to promesify you can be a little smarter:
var Promesify = promesify ( {
methods : [ ' method1 ' , ' method2 ' , ' method3 ' , ]
} ) ;
myApi = new Promesify ( myApi ) ;
myApi . method1 ( ) . method2 ( ) . method3 ( ) . catch ( function ( err ) {
console . log ( ' something went wrong ' ) ;
} ) ;
