Functional Error Handling

A fail-fast module for idiomatic splitting error handling from successful continuation.

Installation

The easiest way is to keep fp-error-handling as a devDependency in your package.json.
``json
{
"devDependencies": {
"fp-error-handling": "1.0.0"
}
}
`

You can simple do it by:
`bash
npm install fp-error-handling --save-dev
`

Example

`javascript
var MongoClient = require('mongodb').MongoClient,
url = 'mongodb://localhost:27017/myproject';

MongoClient.connect(url, function(err, db) {
if(err) {
console.log(err);
return;
}

console.log("Connected correctly to server");

db.close();
});

`

... _becomes_ ...


`javascript
var MongoClient = require('mongodb').MongoClient,
url = 'mongodb://localhost:27017/myproject',
failFast = require('fp-error-handling');

MongoClient.connect(url, failFast(
function(err){
console.log(err);
},
function(db){
console.log("Connected correctly to server");
db.close();
}
));
`

Usage

* callback - (optional) the callback function that fp-error-handling` will split error handling for,
