fp-error-handling

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.

{
  "devDependencies": {
    "fp-error-handling": "1.0.0"
  }
}

You can simple do it by:

npm install fp-error-handling --save-dev

Example

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 ...

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();
    }
));
