atry v0.0.1

atry - async try

Asynchronous try-catch based on Node.JS domain module.

• atry(runningFunction, [arg1, [arg2, ...]])

• .catch(errorHandler) - Catches both synchronous and asynchronous exceptions

   atry(function() {
     setTimeout(function() {
       throw new Error("Got error");
     }, 10);
   }).catch(function(err) {
     console.log("Got error", err);
   });

• .ignoreCatch(errorHandler) - Ignores both synchronous and asynchronous exceptions

   atry(function() {
     setTimeout(function() {
       throw new Error("Got error");
     }, 10);
   }).ignoreCatch(); // ignore exceptions

• atry.bind(bindFunction).catch(catchFunction) - Returns function that will be exception safe

     fs.readFile('someFile', atry.intercept(function(err, data) {
       if(err) throw err; // this will be caught below
       console.log("Got data");
     }).catch(function(err) {
       console.log("got error during file reading", err);
     }));

• atry.intercept(bindFunction).catch(catchFunction) - Returns function that will be exception safe and its first argument will be handled as if it is err.

     fs.readFile('someFile', atry.intercept(function(data) {
       console.log("Got data");
     }).catch(function(err) {
       console.log("got error during file reading", err);
     }));
