try.catch v1.1.1
try.catch
Simple performant try-catch wrapper.
This utility is used in place of regular try/catch
blocks using a clean functional syntax. Execution is fully synchronous; this does not work with async methods
Instead of this
try {
// do something
}
catch (err) {
// handle errors
}
finally {
// finally do something
}
Do this
var Try = require('try.catch');
Try(function () {
// do something
})
.catch(function (err) {
// handle errors
})
.finally(function () {
// finally do something
});
It can also be used like this:
function doSomething (x, y) {
return this + x * y;
}
var result = Try(doSomething, 'test', 2, 3) // pass context and arguments to function
.catch(function (err) {
// err was thrown
}) // chain catch blocks
.catch(TypeError, function (err) { // catch errors conditionally
// TypeError was thrown
})
.finally(function (value, err) {
// finally do something
});
console.log(result.value); // return value of function if any
console.log(result.error); // error thrown if any
