Package Exports

clean-obj

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (clean-obj) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Clean objects in javascript,deleting undefined and null properties of objects

Installation

npm install clean-obj

Basic Usage

cleanObj(obj [,strict]);

var cleanObj = require('clean-obj');

var obj = {
    setted : 'value',
    undf : undefined
};

obj = cleanObj(obj);
    
// Outputs { setted : 'value' }

Strict Mode

If strict mode is set to true it will delete properties that are null and undefined.

Default is false.

Example

var cleanObj = require('clean-obj');

var obj = {
    setted : 'value',
    undf : undefined,
    nullKey : null
};

obj = cleanObj(obj, true);
    
// Outputs { setted : 'value' }

Practical Application

Using express and mongoose (schema database)

If you want to get all possible values on req.body and filter the ones that weren't sent without getting some warnings or errors, you could do the following

Example of update method using mongoose (using model.findOne because of validation middlewares)

model.findOne({id : req.param('id')}, {}, function(err, doc) {
if(err) {
    res.json(resError(err));
} else {

    var obj = {
        email : req.body.email,
        password : req.body.password,
        role : req.body.role
    };
    
    obj = cleanObj(obj, true);

    deepExtend(doc, obj);
    
    doc.save(function(err) {
        if(err) {
            res.json(resFail(err));
        } else {
            res.json(resOkay());
        }
    });
}
});
